What role will edge computing play in telecom networks that are quickly becoming more virtualized and software-centric, and what challenges does multi-access edge computing present for service assurance? Network and service assurance needs are evolving rapidly, as more applications — both network functions that support...

Introduction Software-defined networking (SDN) offers the promise of increased agility, programmability, and revenue services opportunities. While SDN has been widely deployed in the data center and enterprise environments, and many service provider deployments are underway, I think the best is yet to come. According to...

  The increasing virtualization of telecom networks offers the promise of faster launches of new services. But are back-end business and operational systems ready to support the flexibility and rapid services launches that SDN/NFV is supposed to provide? Now that operators are past their first steps toward...

Virtualization and software-defined networks have been the industry’s pre-occupation for almost a decade. It’s all part of a journey toward the deployment of 5G, which will be our next focus for the coming decade. Along the way, one of the key dimensions of the...

Nokia frame deals cover RAN, transport, NFV, SDN and services Nokia came out of the China International Import Expo in Shanghai this week with more than $2 billion worth of deals in place with the country's three mobile operators--China Mobile, China Telecom and China Unicom....

  As service providers transform their networks from traditional, physical infrastructure to a more dynamic, virtual one, they face new challenges in delivering high service quality across an increasingly complex hybrid network. Service assurance tools and processes have always been instrumental in helping achieve service excellence,...

EXFO's sales up, profits down EXFO reported a quarter that its CEO described as disappointing, but promised that 2019 will be a year of renewed focus on execution by the test company, which has had a number of recent acquisitions. Sales for the company's fiscal...

Dissecting a poignant phrase coined at this week’s SDN NFV World Congress On day one of this year’s SDN NFV World Congress in The Hague, I was intrigued by a phrase used in the keynote: ‘fake virtualization’. The speaker, Jehanne Savi, Executive Leader, All-IP & On-Demand...

Offloading traffic at the edge holds the key to making the economics of 5G service delivery tenable. From keeping video traffic local to enabling ultra-low latency operations for autonomous vehicle operations, the ability to provision virtual network elements at the edge and then manage...

  Network functions virtualization (NFV) and software-defined network (SDN) are spearheading the shift toward virtualization, with multi-access edge computing (MEC) serving as a way to alleviate some of the cloud’s workload. As manufacturers look to MEC to enable various smart devices, NFV and SDN are...

Download the latest edition of NI’s Wireless Research Handbook, which includes research examples from around the world and across a wide range of advanced wireless research topics. This comprehensive look at next-generation wireless systems will offer you a more in-depth view of how prototyping...

The ideas around Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), each in their own right, have been around in the industry for many years. They have garnered significant interest in the marketplace as methods to break the vertical market stranglehold that vendors have...

CableLabs, Aricent collaborated on the platform built on the Kubernetes and Docker container model Cable research organization CableLabs and design and engineering company Aricent have been collaborating on an open-source network function virtualization platform aimed at enabling a cloud-native environment for lab and development work...

  The move to Internet Protocol Version 6 addresses has been underway for a number of years, as the world exhausted the supply of IPv4 internet addresses. The momentum in software-defined networking and the internet of things is driving faster adoption of IPv6 -- and...

Trends include growing dependence on remote access, increased bandwidth demand and difficulty in troubleshooting Enterprise IT teams face substantial challenges in successfully managing hybrid networks, according to Viavi Solutions's newly released 2018 State of the Network report. For the second year in a row, IT...

InterDigital and Orange demoed a service-based architectural approach to the 5G control plane 5G, as it continues to develop and be built out, is envisioned as a flexible connectivity medium that trades off proprietary equipment for a cloud-native architecture supported by low-cost, white box server...

Quo vadis SDN in provider networks? With its promise of network simplification and new revenue streams, software-defined networking has certainly captured the interest of service providers. At its core, this technology is about disaggregating physical network functions from software control, creating an ecosystem of open...

  As communications service providers (CSPs) continue to transition their networks to a virtualized environment, for the next several years, they’ll be operating their legacy physical network in tandem. The resulting hybrid network environment demands higher efficiency and interoperability in the provisioning and deployment of...

  The first 5G networks may be commercially ready by the end of this year. Mobile subscribers are within sniffing distance of lightning-fast 5G, a truly exciting prospect after years of build-up, speculation, discussion and…yes…some hype. 5G will open up use cases and business revenue...

Flexibility, scalability, time-to-market key drivers of SDN adoption Software-defined networking (SDN) provides the management and orchestration tools needed to operate increasingly complex and increasingly virtualized networks. For operators, SDN creates efficiencies related to both spectral and network resource allocation, as well as related to level...

In this installment of Network Slicing 101, we’ll examine the basics of network virtualization as applied to network slicing. When we hear about network slicing, one of the most common attributes associated with the concept is the notion that the slices will need to be...

Computer vision is powering advances in automotive, medical, consumer, and agriculture markets. Because the world of computer vision coupled with machine learning evolves so quickly, teams need a way to design and verify an algorithm while the specifications and requirements evolve without starting over...

The need for interoperability Network interoperability has become increasingly important in the telecommunications industry with the emergence network functions virtualization (NFV) and software-defined network (SDN). These sorts of technologies have freed customers from vendor lock-in by replacing proprietary hardware with open source software, which allow...
