Q&A: Mukaddim Pathan, Principal End-to-End Architecture & Technology Practices at Telstra

Telecoms.com periodically invites third parties to share their views on the industry’s most pressing issues. In this article Network Virtualization Asia spoke to Mukaddim Pathan, Principal End-to-End Architecture & Technology Practices at Telstra about the role of Autonomous Continuous/Continuous Deployment in virtualization roll-outs.

Network Virtualization Asia (NVA): Can you start by telling us a bit about the network virtualization space in Australia at the moment? 

Mukaddim Pathan (MP): Alike the rest of the global industry, the Telecommunications companies in Australia are focusing on developing their capabilities in the area of virtualization. In particular, the focus has been on transforming the network, as SDN/NFV technology paradigm gets maturity to provide the same level of Telco-grade performance, resiliency, disaster recovery, and failover capabilities.

In order to reduce the unit cost of delivery, whilst maintaining a lean and modern operational model, service providers are consistently relying on virtualization technologies. Furthermore, with an increasing use of virtualization across the technology stack, we often see the rise of multi-cloud, multi-tenancy environments.

NVA: With that in mind, what are Telstra currently doing in the space to advance it? 

MP: Telstra has a dedicated Network Evolution 2020 (NE2020) program, which has a strong focus on Agile ways of working, and is underpinned by virtualization, automation, orchestration, data and standards-based API.

As mentioned, “Network Function Virtualization infrastructure” (NFVi) is an essential part of the NE2020 program, as it helps us to deliver a low cost, open standards network cloud ecosystem, at scale, and to support the transformation of Telstra’s network.

Furthermore, NFV & SDN enable the transition of hardware appliance centric functions to software centric tenants on centrally engineered platform/ecosystem. Cloud-enabling our infrastructure by adopting SDN/NFV throughout the network includes a number of key initiatives that are currently being undertaken:

  • Virtualization of existing/new network functions with the introduction of resource and service orchestration.
  • Automated VNF On-boarding and lifecycle management of virtual network services.
  • Make services available through standards-based APIs and provisioned through Infra as a Code and containerized solutions.
  • Automate delivery/operational aspects for various network services using a home grown end-to-end Continuous Integration and Continuous Deployment (CI/CD) platform for build/configuration management, test management, release management, and inventory management.

NVA: How are VNFs being introduced into the network today? Why do you think they are so important for progress in the industry?

MP: Telstra has been working with partners to progressively introduce VNFs in our network. Whilst the industry is still maturing in establishing best practices in VNF packaging and automated VNF onboarding solutions, it is important for service providers to set guidelines to the partners on the way VNFs are prepared and provided to them.

As an industry leader, Telstra has developed automated onboarding process for VNFs and established workflows using an integrated CI/CD platform, which has led to efficient onboarding of VNFs, potentially reducing the lead time from months to days.

Whilst VNF onboarding focuses on providing a common user experience and standards-based framework to on-board and life cycle manage workloads in a multi-cloud / multi-VIM NFVi environment, it leverages end-to-end CI/CD and automation capabilities for workload evaluation, packaging, certification and deployment of various network functions.

NVA: And, how do things like Automation and CICD practices come into play with this? 

MP: Automation and CI/CD practices are key in managing and evolving virtualized infrastructure within the service provider’s environment. As the network becomes software centric, it is important that these practices are leveraged for ensure seamless maintenance and management (device, configuration etc) of network elements.

At Telstra we have deployed a modular, scalable, extensible and centralized CI/CD and automation platform that provides fully integrated and ready to use capabilities and tools as a shared service across Networks by consolidating and standardizing multiple functionalities (including but not limited to pipeline management, configuration management, repositories, test management, artefact management etc) and toolsets.

A flexible and re-usable test automation enablement layer is added for various network/IT services that converges the test automation process through a single channel. It allows seamless integration of test tools with the agile management layer and exposed to various consumers by Restful APIs.

NVA: With all these advancements, how do you think operators fit into the virtualization space today? What is their role?

MP: The role of service providers in the virtualization space is key, as NFV & SDN enable the “softwarisation” of the network and assist transition of network functions onto a centrally engineered platform/ecosystem. NFV/SDN and evolution to a software defined network should be a foundational tenant for a service provider’s growth strategy, and they can influence this space by:

  • Adopting template driven and modular architecture for highly configurable and extensible solution (enabling multi cloud support)
  • Promoting containerised and Microservices driven approach for distribution and scalability
  • Supporting automated deployment of virtual network overlay including Vlinks, subnets etc. using simplified tools.
  • Enabling automated deployment network functions and virtualized infrastructure as code

NVA: Can you tell us about your upcoming talk at Network Virtualization Asia? What attracted you to the event, and can you reveal a little about what you will be discussing?

MP: In my talk, I’ll discuss how the operators are relying on Automation and Continuous Integration/Continuous Deployment (CICD) practices, as Virtual Network Functions (VNFs) are introduced within the network, yet operators have the need to manage the existing physical infrastructure. It will be linked to Telstra’s NE2020 architecture, whereby we have deployed an abstraction layer to enable underlying technology domains to conduct orchestration, exposing relevant network services for consumption. One specific example I would cover is how VFNs are onboarded onto the network, configured, and lifecycle managed using the software engineering practices, and orchestrated via the stated network abstraction layer.

Virtualization and Automation are key technology themes that are being leveraged in the way we develop solutions to meet Telstra’s long-term objectives of growth and cost reduction. As we focus on our efficiency and productivity targets, industry knowledge and relevant practical applications will be key. It is important that we keep ourselves up-to-date on the industry trends by actively participating in major global events such as Network Virtualization & SDN Asia.

For me, it is the premier event in the APAC region, which focuses on SDN, NFV and automation topics that are highly relevant to us. Crucially, by participating in this event, I’m able to connect with global Telco peers and share knowledge on the emerging topics such as SDN/NFV, Edge Computing, Automation and 5G, as well as learn from peers and apply their findings in the service provider context.

 

Dr. Mukaddim Pathan heads up the End-to-End Architecture & Technology Practices group for Networks & IT within Telstra, the largest Telecommunications company in Australia. At Telstra, his key responsibility is to deliver architecture and technical solutions towards Telstra 2022 (T22) outcomes, specifically focusing on network abstraction, edge computing, automation, and 5G use cases.

AT&T gets Microsoft and IBM to help with its cloud homework

US telco AT&T has decided it’s time to raise its cloud game and so has entered into strategic partnerships with Microsoft and IBM.

The Microsoft deal focuses on non-network applications and enables AT&T’s broader strategy of migrating most non-network workloads to the public cloud by 2024. The rationale for this is fairly standard: by moving a bunch of stuff to the public cloud AT&T will be able to better focus on its core competences, but let’s see how that plays out.

IBM will be helping AT&T Business Solutions to better provide solutions to businesses. The consulting side will modernize its software and bring it into the IBM cloud, where they will use Red Hat’s platform to manage it all. In return IBM will make AT&T Business its main SDN partner and general networking best mate.

“AT&T and Microsoft are among the most committed companies to fostering technology that serves people,” said John Donovan, CEO of AT&T. “By working together on common efforts around 5G, the cloud, and AI, we will accelerate the speed of innovation and impact for our customers and our communities.”

“AT&T is at the forefront of defining how advances in technology, including 5G and edge computing, will transform every aspect of work and life,” said Satya Nadella, CEO of Microsoft. “The world’s leading companies run on our cloud, and we are delighted that AT&T chose Microsoft to accelerate its innovation. Together, we will apply the power of Azure and Microsoft 365 to transform the way AT&T’s workforce collaborates and to shape the future of media and communications for people everywhere.”

“In AT&T Business, we’re constantly evolving to better serve business customers around the globe by securely connecting them to the digital capabilities they need,” said Thaddeus Arroyo, CEO of AT&T Business. “This includes optimizing our core operations and modernizing our internal business applications to accelerate innovation. Through our collaboration with IBM, we’re adopting open, flexible, cloud technologies, that will ultimately help accelerate our business leadership.”

“Building on IBM’s 20-year relationship with AT&T, today’s agreement is another major step forward in delivering flexibility to AT&T Business so it can provide IBM and its customers with innovative services at a faster pace than ever before,” said Arvind Krishna, SVP, Cloud and Cognitive Software at IBM. “We are proud to collaborate with AT&T Business, provide the scale and performance of our global footprint of cloud data centers, and deliver a common environment on which they can build once and deploy in any one of the appropriate footprints to be faster and more agile.”

Talking of the US cloud scene, the Department of Defense is reportedly looking for someone to provide some kind of Skynet-style ‘war cloud’ in return for chucking them $10 billion of public cash. Formally known as the Joint Enterprise Defense Infrastructure (yes, JEDI), this is designed to secure military and classified information in the event of some kind of catastrophic attach, contribute to cyber warfare efforts and enable the dissemination of military intelligence to the field.

It looks like the gig will be awarded to just one provider, which had led to much jostling for position among the US cloud players. The latest word on the street is that either AWS or Microsoft will get the work, which has prompted considerable moaning from IBM and Oracle and reported concern from President Trump, prompted by politicians apparently repaying their lobbying cash. Here’s a good summary of all that from Subverse.

Q&A with Rupesh Chokshi – Assistant Vice President, Edge Solutions Product Marketing Management, AT&T Business

Telecoms.com periodically invites third parties to share their views on the industry’s most pressing issues. Rupesh Chokshi is a leader in technology with a strategic focus for growth in global technology and telecommunications. He currently leads the product marketing team within Edge Solutions for AT&T Business which focuses on product management, strategy and business development, and is transforming services and networks using software-defined networking (SDN), network function virtualization (NFV) and SD-WAN technologies.

To help determine the state of virtualization today, Light Reading spoke with Rupesh Chokshi – Assistance Vice President, Edge Solutions Product Marketing Management at AT&T Business – and one of the industry leading experts presenting at this years’ Network Virtualization & SDN Americas event in September.

Light Reading (LR): How has network virtualization evolved in the last three years?

Rupesh Chokshi (RC): AT&T has been in the business of delivering software-centric services for several years, and we’ve seen adoption from businesses looking to update their infrastructures, increase their agility and transform their businesses. Networks are almost unrecognizable from what they used to be – data traffic on our mobile network grew more than 470,000% since 2007, and video traffic increased over 75% in the last year. Given the new network demands, companies need to adapt by changing the way they manage networks.

We took a unique approach with our infrastructure ability by using software-defined network (SDN) and network function virtualization (NFV) with our own network, meeting our goal of 65% virtualized network by 2018 and setting us up to achieve our goal of 75% virtualization by 2020. At the same time we started using SDN and NFV in our own network, we utilized SDN to deliver AT&T’s first SDN service, AT&T Switched Ethernet Service with Network on Demand (ASEoD). This allowed thousands of customers to provision and manage their network in a fraction of the time it took in the past, and now enables them to scale bandwidth on demand to meet their business’ seasonality.

ASEoD was only the first of a series of solutions we are creating to address shifting network needs. Three years ago, we introduced our first global software-based solution, AT&T FlexWareSM, which uses both SDN and NFV to increase business agility by simplifying the process for dynamically adding and managing network functions.

LR: What technology developments are you most excited about for in the future?

RC: The work we did up to this point to deliver SDN within our network and for our customers set us up for the next generation of wireless technology, 5G. As the first SDN-enabled wireless technology, and the first wireless network born in the cloud, 5G will ultimately enable new use cases that take advantage of network slicing, the ability to support a high number of IoT devices and greater low-latency edge compute capabilities.

In addition, we are collaborating with VMWare SD-WAN by VeloCloud to implement 5G capabilities into our software-defined wide area networking (SD-WAN). This will give business new levels of control over their networks and is key for companies looking to use SD-WAN with a high-speed, low-latency 5G network as their primary or secondary WAN connection type.

LR: How can businesses move forward with virtualization today?

RC: Today, businesses need to make sense of data faster and more efficiently than ever before, which is driving businesses to evaluate how they use their network for all applications, and to find ways to maximize their resources. One-way companies can do this and move forward with virtualization is through AT&T’s comprehensive SD-WAN portfolio. AT&T’s SD-WAN technology supports this new way of working by letting companies define policies based on individual business needs using centralized software-based control.

LR: How can businesses determine the business benefits and ROI of virtualization today?

RC: Businesses can determine the business benefits of virtualization through cost savings, application-level visibility and near real-time analytics.

Potential cost savings is one of the key benefits of SD-WAN that is touted by technology suppliers and service providers alike. In our experience, it is during the process of fleshing out the technical details of the solution and how to best integrate it into their network that enterprises begin to fully appreciate where those cost benefits may come from, as well as understanding other benefits or features that may also be important to them. Keep in mind the importance of considering potential cost savings in the context of total cost of ownership, not just looking at the relative cost of the CPE vs. the cost of the network access.

Additionally, SD-WAN technology can provide more application-level visibility and control on a per site basis, and these capabilities go far to help customers assess and experience the benefits of the performance of their network access and transport.

SD-WAN also enables customers to access analytics in near real time or on a historical basis for bandwidth consumption and application visibility. This is instrumental in setting KPIs and measuring ROI and planning for future network growth.

LR: What virtualization strategies should businesses be focusing on?

RC: Businesses need to adopt efficient, high-performing networks to take advantage of the newest technology and bandwidth needs. Automation is a great example of this. As businesses require more bandwidth, we need to provide more elegant solutions in order for them to take full advantage of more ubiquitous, high-speed broadband.

Additionally, while digital transformation is top of mind for businesses of all sizes and in every industry, dynamic SD-WAN is still in a relatively early stage of growth and adoption. And for others, MPLS and IPsec remain important options. Hybrid WAN designs will continue to be popular as customers utilize multiple technologies (MPLS, IPSec, SD-WAN) for optimal results.

LR: How can businesses build these technologies into their long-term business models?

RC: We live in a digital economy, and AT&T provides fundamental platforms for businesses to grow, differentiate and innovate. We work with businesses of all sizes to help transform their long-term business models through technology solutions delivered in the form of a managed service. Customers come to us because of our expertise, breadth and depth of capabilities, global scale and innovation in areas such as software defined networking, network function virtualization, mobility, IoT and SD-WAN.

As businesses grow, they need to think about their overall networking health. And how they can use their networks to meet all their business objectives. Key considerations in bringing that to life include:

  • Holistic solutions that can combine SD-WAN functionality with network services from AT&T or other providers, virtualized CPE, wired and wireless LAN, security, voice over IP and much more;
  • Reduced operational expense and less need for in-house expertise with a managed solution that handles all aspects of the end-to-end solution design and setup;
  • Global deployment options that remove the headaches of onsite installation and support in countries around the world; and
  • Flexible SD-WAN policy management where the customer can choose to set and update application level policies themselves or rely on AT&T experts to manage this for them.

BT looks to Juniper to trim the network bloat

BT has opted for Juniper Networks to deliver its Network Cloud infrastructure initiative, paving the way for BT’s Network Cloud roll-out.

The platform itself is designed to offer BT a number of different upgrades to its current position, including improvements to converged fixed and mobile services rollout to consumers and businesses, faster time-to-market for network services and improved voice and video deliverability and scalability.

The initiative will hope to roll BT’s networks including 5G, Wi-Fi and fixed-line into one virtualised service, a common framework which can be shared across all BT offices nationally and globally. Moving into the single framework will also help BT deliver cost efficiency saving, a key component of recent strategies to make the telco into a leaner machine.

Aside from the EE component of the business, BT has been one of the more sluggish players in the telco space, with the spreadsheets bearing the brunt. If BT is to make the most of up-coming connectivity evolutions, IOT and 5G for example, the business needs to be in a fitter position. This initiative is one of the strands of this plan.

“This move to a single cloud-driven network infrastructure will enable BT to offer a wider range of services, faster and more efficiently to customers in the UK and around the world,” said Neil McRae, Chief Architect at BT. “Being able to integrate seamlessly with other partners and solutions and aligning with our roadmap to an automated and programmable network is also important.”

“By leveraging the ‘beach-front property’ it has in central offices around the globe, BT can optimize the business value that 5G’s bandwidth and connectivity brings,” said Bikash Koley, CTO at Juniper Networks. “The move to an integrated telco cloud platform brings always-on reliability, along with enhanced automation capabilities, to help improve business continuity and increase time-to-market while doing so in a cost-effective manner.”

For Juniper, the bean-counters will be happy with the win, with numerous services being undertaken across different aspects of the network. Contrail Networking will be used for dynamic end-to-end networking policy and control for telco cloud workloads, AppFormix will run the cloud operations management suite, while the QFX Series also features.

The reality of mobile SD-WAN – the missing link for enterprise 5G?

Telecoms.com periodically invites third parties to share their views on the industry’s most pressing issues. This is the second of a two piece series in which Simon Pamplin, EMEA Technical Sales Director for Silver Peak, looks at some of the enterprise benefits of the latest generations of wireless networking technology.

This is the second of a two-part article series that explores SD-WAN and the future of networking in the 5G era. The first looked at how established 4G LTE connectivity, partnered with software-defined WANs (SD-WANs), have contributed to changing the way users connect to applications, particularly for ‘on-the-go’ requirements and in hard to reach locations.

5G: forging the new ultra-high speed, hyperconnected world

Following the 5G spectrum auction in the UK back in April of 2018, telecommunications providers are now racing to roll out the fifth generation of mobile wireless technology to meet today’s explosive bandwidth and network connectivity demands. 5G is poised to revolutionise several industries by bringing significantly faster connections, shorter delays and increased connectivity for users. It will aid the expansion of IoT, creating a virtual network of ultra-high-speed connections across multiple devices.

According to Gartner, two thirds of large organisations have plans to deploy 5G by 2020. However, a full end-to-end deployment will take many more years. The firm also projects that the lack of readiness of communications service providers to meet enterprise demands in time will be a major issue.

Looking at the near term, service providers have to provide means to enable use cases – such us IoT communications, enhanced mobile broadband, fixed wireless access along with high-performance edge analytics – without having the benefit of an end-to-end 5G network. This is all while contending with sky high user expectations.

SD-WAN is one of those enabling technologies that will help service providers to deliver a higher quality of network experience that is tailored to the customer’s needs, while managing the transition to a complete end-to-end 5G infrastructure for delivery.

5G: on the edge

According to Gartner, the number of IoT devices is set to rise to more than 20 billion by 2020. IoT connectivity across more and more devices will drive the processing of high volumes of data at high speed – one of the core promises of 5G. This influx of data must be ingested and processed both in real time, and as close to the source as possible, ultimately driving the need for edge computing.

While 5G provides higher bandwidth, it is more limited in range. It is anticipated that 5G networks will be powered by hundreds of thousands of small cells. Denser networks of cells will make it more difficult for operators to operate, manage and maintain. As such, the optimisation of these networks will be key to deliver the best possible network performance and maintain the highest quality of experience to end users.

The emergence of 5G will not only change end users’ expectations when it comes to always-on connectivity and low latency, it will also transform the way enterprises manage their networks. Strong demands on real-time network monitoring across transport connectivity and traffic management optimisation will drive the need for automation.

SD-WAN can hold the 5G ends together but what features will be most valuable?

SD-WAN connects users to applications securely and directly using any combination of underlying transport, including MPLS, 4G LTE and internet. As companies roll out 5G in the UK, businesses with SD-WANs deployed on the network will have the ability to transition key parts or locations over to the latest high-speed, high-performance connectivity.

An SD-WAN platform that enables automation will help service providers to easily connect to and integrate across all the different compute edges required to optimise the traffic and management of 5G cells. This will enable a seamless transition towards a full 5G infrastructure by managing any transport available across the edge, leveraging 5G transport for those critical applications that require zero latency and higher speeds.

To guarantee the highest quality of experience for users, service providers need to evaluate SD-WAN vendors. The best vendors and solutions will be those that are able to offer advanced features. One of these is granular, intelligent application-driven routing. In Layman’s terms, this means the SD-WAN can automatically prioritise high-bandwidth, or business critical, traffic (like video streaming) to a 5G cell and manage failovers, while lower bandwidth traffic is routed to another transport available (such as LTE or broadband internet).

Moreover, centralised orchestration and management capabilities can facilitate easier operation, management and maintenance of edges and 5G cells by intelligently rerouting traffic during cell provisioning or upgrades. It also enables faster policy-based provisioning of WAN services to support any device – a must for IoT.

With business around the world ramping up cyber defences, an SD-WAN that also unifies security features with business intent networking is more favourable. These enable the centralised enforcement of granular, application-driven security policies by identifying, classifying and automatically steering traffic to the right security services without compromising either performance or cost.

Enterprises expect the best quality of service (QoS) that applications demand and SD-WAN solutions with virtual WAN overlays can allow for a more efficient and flexible allocation of network resources. Similarly, 5G networks rely on network slicing, where each slice receives a unique set of optimised resources and network topology. By using both technologies together, service providers can steer mission-critical traffic to the 5G network, where it can be isolated to a particular slice depending on the specific application requirements.

Lastly, as SD-WAN continues to evolve, emerging technologies will be incorporated to further enhance the user experience. Today, SD-WAN solutions that utilise machine learning separate themselves from the crowd. These can automatically adapt to varying network conditions in real time and provide optimal routing to the edges and the 5G small cells.

5G & SD-WAN: powering forward-thinking businesses

The adoption of 5G and edge computing will drive higher expectations from end users and enterprises for an always-on, high performing network and applications. The initial success of 5G deployments will demand an automated, self-driving wide area network foundation with underlay intelligence that delivers the highest quality of experience for users, such as the one offered by SD-WAN. Additionally, advanced business-driven SD-WAN platforms will empower service providers with ways to accelerate new revenue streams from 5G-enabled managed services rather than just as a transport connection.

With over 20 years’ experience in enterprise IT, Simon has worked for IP, SAN and hyper-convergent companies and is driven by new technology and the business benefits it can bring.

The reality of mobile SD-WAN – what 4G LTE made possible

Telecoms.com periodically invites third parties to share their views on the industry’s most pressing issues. This is the first of a two piece series in which Simon Pamplin, EMEA Technical Sales Director for Silver Peak, looks at some of the enterprise benefits of the latest generations of wireless networking technology.

5G, also known as the fifth generation of mobile wireless technology, is one of the hottest topics in wireless circles today. Indeed, you can’t throw a stone without hitting a plethora of titles, potential use cases and detailed explanations about 5G. While telecommunications providers are in a heated competition to roll out 5G, it is important to reflect on current 4G LTE (long term evolution) business solutions as a preview of what has been learned and what’s possible.

At the same time, the enterprise has experienced its own networking revolution. As cloud computing has become the norm, and more applications and services have migrated for enterprise convenience and flexibility, IT departments have realised that traditional wide area network (WAN) architectures – utilising multiprotocol label switching (MPLS) circuits and conventional routers – cannot keep up. As such, to achieve the highest levels of application performance and security, many organisations have turned to software-defined WAN (SD-WAN), the networking technology that connects users directly and securely to applications using any underlying transport, including 4G and broadband internet.

SD-WAN enables enterprises to shift to a business-first networking model, where the network enables the business, rather than the business conforming to the constraints of existing WAN approaches. Instead of being a constraint, the WAN becomes a business accelerant that is fully automated and continuous, giving every application the resources it truly needs, while delivering 10 times the bandwidth for the same budget – ultimately achieving the highest quality of experience to users and IT alike.

This is part one of a two-part article series that will explore the effect of 4G and 5G on enterprise networking, as well as the SD-WAN journey through the evolution of these wireless technologies.

Mobile SD-WAN is a reality

4G LTE commercialisation is continuing to expand. According to the GSM (Groupe Spéciale Mobile) Association, 710 operators have rolled out 4G LTE in 217 countries, reaching 83 percent of the world’s population. The evolution of 4G is transforming the mobile industry and is setting the stage for the advent of 5G.

Mobile connectivity is increasingly integrated with SD-WAN, along with MPLS and broadband WAN services today. The reason being is that 4G LTE represents a very attractive transport alternative, as a backup or even an active member of the WAN transport mix to connect users to critical business applications. In some cases, 4G LTE might be the only choice in locations where fixed lines are not available or reachable. Furthermore, an SD-WAN can optimise 4G LTE connectivity, and bring new levels of performance and availability to mobile-based business use cases by bonding multiple 4G LTE connections to deliver the highest levels of network and application performance.

Increasing application performance and availability with 4G LTE

Best in class SD-WAN solutions enable customers to incorporate one or more low-cost 4G LTE services into the WAN transport mix. Indeed, all the capabilities of the SD-WAN platform – including packet-based link bonding, dynamic path control, and path conditioning – can be supported across multiple LTE links. This ensures always-consistent, always-available application performance even in the event of an outage or degraded service.

With an advanced business-driven SD-WAN edge platform, IT can also incorporate sophisticated network address translator (NAT) traversal technology to eliminate the requirement for provisioning the LTE service with extra-cost static IP addresses. Holistic solutions offer management software that enables the prioritisation of LTE bandwidth usage based on branch and application requirements – active-active or backup-only. This kind of solution is ideally suited toward retail point-of-sale and other deployment use cases where always-available WAN connectivity is critical for the business.

Mobile SD-WAN: innovative connectivity solutions to real world problems

An example of an innovative mobile SD-WAN service is swyMed’s DOT Telemedicine Backpack, powered by an SD-WAN hardware platform. This integrated telemedicine solution enables emergency services first responders to connect to doctors and communicate patient vital statistics using real-time video anywhere, anytime, thereby greatly improving and expediting care for emergency patients. Using a lifesaving backpack provisioned with two LTE services from different carriers, the SD-WAN can continuously monitor the underlying 4G LTE services for packet loss, latency and jitter. In the case of transport failure or brownout, the SD-WAN automatically initiates a sub-second failover so that voice, video and data connections continue without interruption over the remaining active 4G service. By bonding the two LTE links together with the SD-WAN, swyMed can achieve an aggregate signal quality in excess of 90 percent, bringing mobile telemedicine to areas that would have been impossible in the past due to poor signal strength.

Prepare for the 5G future

The adoption of 4G LTE is already a reality. As well as evangelising SD-WAN to end-users, service providers have a vital and value-added role in the design, installation, deployment, repair, and ongoing monitoring of managed SD-WAN services. Indeed, service providers are already taking advantage of the distinct benefits of SD-WAN to offer managed SD-WAN services that leverage flexible and mobile 4G LTE to their customers.

As the race for the 5G gains momentum in the UK – with it expected to be available in multiple cities this year – service providers will no doubt look for ways to drive new revenue streams to capitalise on their initial investments. The next article of this two-part series will discuss the rise of 5G, and how SD-WAN will help service providers to transition from 4G to 5G, as well as enable the monetisation of a new wave of managed 5G services.

Q&A with Sunil Lingayat, Chief of Cyber Strategy and Technology at T-Mobile

Sunil Lingayat leads the cybersecurity strategy architecture and cybersecurity technology functions for T-Mobile and is responsible for driving next generation cyber strategies and capabilities and positioning products and services into an effective cyber resilience posture. The Big 5G Event team interviewed Sunil ahead of the event to gain a sneak peek of what we can expect at our upcoming conference.

What are the unique security requirements for 5G networks?

At a high level there are two primary reasons that are driving unique security requirements for 5G networks.  First is the use of COTS technologies and open architectures, distributed architectures, disaggregation at various layers of the stack, open service-based architecture (HTTP2/JSON), etc.  Second the exponential growth in number of devices (e.g. IoT), higher business value use cases, need for privacy-by-design, need for Safety, Low latency, order of magnitude higher throughout, etc.  Both of these aspects lead to (a) increased attack surface, (2) susceptible to a broader and established attacks and exploits, and higher tier threat actors, and more importantly (3) traditional security architectures and controls will not work, etc ….all contributing to unique security requirements for 5G in comparison to earlier networks – such as requirement for use case driven security, layered security, security automation, and cyber resilience.

What will be the unique security considerations for specialized 5G use cases?

As per ITU, 5G is expected to support three different families of use cases with somewhat conflicting requirements on a couple of dimensions such as latency, integrity, etc.  These are driving the need for slicing or network of networks architecture.  Within each use case type, there is also the dimension of privacy.  Some use cases requiring very stringent privacy e.g., HIPPA.  Whereas some use cases integrity and latency are critical.  It is important that security controls are geared towards each use case.  One size fits all will not work as it will make services very expensive, fragile, and in effect non-operational.

How can a dynamic security architecture be ensured for each network slice?

Software-defined security (SDS) becomes very important for achieving dynamic security. Security orchestration integrated with service orchestration is essential. Security function virtualization is another approach aligned with the VNF and NFVi architectures. All of this need automation at scale from the very beginning in the architecture.  Machine Learning and AI have to be incorporated and fine-tuned for “whitelist” security model and behaviour monitoring.

How can service providers adequately support NFV/SDN security requirements

Virtualization is not new as a technology.  Much innovation and lessons learned in the cloud industry.  Cyber 2.0 cyber resilience design principles like Autonomic security, least privilege, privilege escalation, dynamic alignment, dynamic positioning, etc have to be designed in. Adoption of de-perimeterized security strategy and architecture is crucial so security is not tied to the perimeter or zone.  Security has to be dynamic.  In fact, SDN/NFV can be effectively used to enhance traditional static (host and network-based) security positively and make 5G services cyber-resilient.

Ericsson and Intel partner for 5G cloud platform

Ericsson and Intel have announced a new partnership which is aimed at aligning the Swedes efforts for software-defined infrastructure with Intel’s Rack Scale Design.

The resulting hardware management platform will be designed for telcos targeting 5G, NFV, and distributed cloud. In theory, the pair aims to create a common managed hardware pool for all workloads that dynamically scales. It’s the scalable and affordable dream telcos have been promised for years.

The duo has said the new tie-up will allow telcos to take advantage of multi-vendor hardware options, Ericsson’s end-to-end software solutions, and Intel’s latest architectural solutions.

“We have long history of successful collaboration with Intel. Lars Mårtensson, Head of Cloud & NFV infrastructure for Digital Services at Ericsson. “This new collaboration will focus on software in addition to hardware and we see it to be truly transformative for service providers’ ability to successfully deploy open cloud and NFV infrastructure, from centralized data-centres to the edge. Intel’s and Ericsson’s joint efforts significantly strengthens the competitiveness and roadmap of the Ericsson Software Defined Infrastructure offering.”

“5G will be transformative, accelerating today’s applications and triggering a wave of new usages and edge-based innovation,” said Sandra Rivera, SVP of the Network Platform Group at Intel. “Our infrastructure manageability collaboration with Ericsson will help communications service providers remove deployment barriers, reduce costs, and deliver new 5G and edge services with cloudlike speed on a flexible, programmable and intelligent network.”

As part of the tie up, the Ericsson SDI Manager software and Intel RSD reference software will be converged, though the pair reiterated full backward compatibility would be maintained for existing customers. Any new solutions developed moving forwards will be subsequent Ericsson hardware platforms, as well as Intel’s server products which are sold through third-parties and in other industry segments.

Are you ready to look at 6G?

We can hear the groans already, but we’re going to do it anyway. Let’s have a look at what 6G could possibly contribute to the connected economy.

Such is our desire for progress, we haven’t even launched 5G but the best and brightest around are already considering what 6G will bring to the world. It does kind of make sense though, to avoid the dreaded staggering of download speeds and the horrific appearance of buffering symbols, the industry has to look far beyond the horizon.

If you consider the uphill struggle it has been to get 5G to this point, and we haven’t even launched glorious ‘G’ properly, how long will it take before we get to 6G? Or perhaps a better question is how long before we actually need it?

“5G will not be able to handle the number of ‘things’ which are connected to the network in a couple of years’ time,” said Scott Petty, CTO of Vodafone UK. “We need to start thinking about 6G now and we have people who are participating in the standards groups already.”

This is perhaps the issue which we are facing in the future; the sheer volume of ‘things’ which will be connected to the internet. As Petty points out, 5G is about being bigger, badder and leaner. Download speeds will be faster, reliability will be better, and latency will be almost none existent, but the weight of ‘things’ will almost certainly have an impact. Today’s networks haven’t been built with this in mind.

Trying to find consensus on the growth of IOT is somewhat of a difficult task, such is the variety of predictions. Everyone predicts the same thing, the number of devices will grow in an extra-ordinary fashion, but the figures vary by billions.

Using Ericsson’s latest mobility report, the team is estimating cellular IoT connections will reach 4.1 billion in 2024, of which 2.7 billion will be in North East Asia. This is a huge number and growth will only accelerate year-on-year. But here is thing, we’re basing these judgments on what we know today; the number of IOT devices will be more dependent on new products, services and business models which will appear when the right people have the 5G tools to play around with. Who knows what the growth could actually be?

IOT Growth

Another aspect to consider is the emergence of new devices. As it stands, current IOT devices deliver such a minor slice of the total cellular traffic around the world its not much of a consideration, however with new usecases and products for areas such as traffic safety, automated vehicles, drones and industrial automation, the status quo will change. As IOT becomes more commonplace and complicated, data demands might well increase, adding to network strain.

Petty suggests this will be the massive gamechanger for the communications industry over the next few years and will define the case for 6G. But, who knows what the killer usecase will be for 5G, or what needs will actually push the case for the next evolution of networks. That said, more efficient use of the spectrum is almost certainly going to be one of the parameters. According to Petty, this will help with the tsunami of things but there is a lot of new science which will have to be considered.

Then again, 6G might not be measured under the same requirements as today…

Sooner or later the industry will have to stop selling itself under the ‘bigger, badder, faster’ mantra, as speeds will become irrelevant. If you have a strong and stable 4G connection today, there isn’t much you can’t do. Few applications or videos that are available to the consumer require 5G to function properly, something which telco marketers will have to adapt to in the coming years as they try to convince customers to upgrade to 5G contracts.

4G and arguably todays vision of 5G has always been about making the pipe bigger and faster, because those were the demands of the telcos trying to meet the demands of the consumer. 6G might be measured under different KPIs, for example, energy efficiency.

According to Alan Carlton, Managing Director of InterDigital’s European business, the drive towards more speed and more data is mainly self-imposed. The next ‘G’ can be defined as what the industry wants it to be. The telcos would have to think of other ways to sell connectivity services to the consumer, but they will have to do that sooner or later.

The great thing about 5G is that we are barely scratching the surface of what is capable. “We’re not even at 5.0G yet,” said Carlton. “And this is part of the confusion.”

What 5G is nowadays is essentially LTE-A Pro. We’re talking about 256-QAM and Massive MIMO but that is not really a different conversation. With Release 16 on the horizon and future standards groups working on topics such virtualisation, MMwave and total cost of ownership, future phases of 5G will promise so much more.

The next step for Carlton is not necessarily making everything faster, or more reliable or lower latency, but the next ‘G’ could be all about ditching the wires. Fibre is an inflexible commodity, and while it might be fantastic, why do we need it? Why shouldn’t the next vision of connectivity be one where we don’t have any wires at all?

Carlton’s approach to the future of connectivity is somewhat different to the norm. This is an industry which is fascinated by the pipes themselves and delivering services faster, but these working groups and standards bodies are driving change for the benefit of the industry. It doesn’t necessarily have to be about making something faster, so you can charge more, just a change to the status quo which benefits the industry.

Coming back to the energy efficiency idea, this is certainly something which has been suggested elsewhere. IEEE has been running a series of conferences in California addressing this very issue, as delivering 1000X more data is naturally going to consume more energy to start with. It probably won’t be 1000X more expensive, but it is incredibly difficult to predict what future energy consumption needs will be. Small cells do not consume as much energy as traditional sites, but there will need to be a lot more of them to meet demand. There are a lot of different elements to consider here (for example environment or spectrum frequency), but again, this is a bit of an unknown.

Perhaps this is an area where governments will start to wade in? Especially in the European and North American markets which are more sensitive to environmental impacts (excluding the seemingly blind Trump).

Echoing Petty’s point from earlier, we don’t necessarily know the specifics of how the telco industry is going to be stressed and strained in six- or seven-years’ time. These changes will form the catalyst for change, evolving from 5G to 6G, and it might well be a desire for more energy efficient solutions or it might well be a world free of wires.

Moving across the North Sea, 6G has already captured the attention of those in the Nordics.

Back in April 2018, the Academy of Finland announced the launch of ‘6Genesis’, an eight-year research programme to drive the industry towards 6G. Here, the study groups will start to explore technologies and services which are impossible to deliver in today’s world, and much of this will revolve around artificial intelligence.

Just across the border in Sweden, these new technologies are capturing the attention of Ericsson. According to Magnus Frodigh, Head of Ericsson Research, areas like Quantum computing, artificial intelligence and edge computing are all making huge leaps forward, something which will only be increased with improved connectivity. These are the areas which will define the next generation, and what can be achieved in the long-run.

“One of the new things to think about is the combination of unlimited connectivity as a resource, combined with low latency, more powerful computing,” said Frodigh. “No-one really knows how this is going to play out, but this might help define the next generation of mobile.”

Of course, predicting 6G might be pretty simple. In a couple of years’ time, perhaps we will all be walking around with augmented reality glasses on while holographic pods replace our TVs. If such usecases exist, perhaps the old ‘bigger, badder, faster’ mantra of the telco industry will be called upon once again. One group which is counting on this is EU-funded Terranova, which is currently working on solutions to allow network connection in the terahertz range, providing speeds of up to 400 Gbps.

Another area to consider is the idea of edge computing and the pervasiveness of artificial intelligence. According to Carlton (InterDigital), AI will be every in the future with intelligence embedded in almost every device. This is the vision of the intelligent economy, but for AI to work as promised, latency will have to be so much lower than we can even consider delivering today. This is another demand of future connectivity, but without it the intelligent economy will be nothing more than a shade of what has been promised.

And of course, the more intelligence you put on or in devices, the greater the strain on the components. Eventually more processing power will be moved off the devices and into the cloud, building the case for distributed computing and self-learning algorithms hosted on the edge. It is another aspect which will have to be considered, and arguably 5G could satisfy some of these demands, but who knows how quickly and broadly this field will accelerate.

Artificial intelligence and the intelligent economy have the potential to become a catalyst for change, forcing us to completely rethink how networks are designed, built and upgraded. We don’t know for sure yet, but most would assume the AI demands of the next couple of years will strain the network in the same way video has stressed 4G.

Who knows what 6G has in store for us, but here’s to hoping 5G isn’t an over-hyped dud.
