Evaluating Nokia's VNFs: Part 2

Whether a network function is deployed on a dedicated hardware platform or as a virtual network function (VNF), communications service providers (CSPs) need to be sure they are going to get a certain level of performance at real-world operational scale: "Carrier grade" is not optional -- it's a must have.

So as CSPs start to introduce VNFs into their next-generation network rollout plans, one of the main questions they'll be asking as their vendor partners offer virtual alternatives to traditional bespoke boxes is -- can VNFs achieve carrier-grade performance levels?

That's why Light Reading's independent test lab partner, EANTC, has focused on performance and scalability during its recent evaluations of a number of Nokia VNFs.

Earlier this year, Light Reading published a test result report following EANTC's evaluation of Nokia's Virtualized Service Router (VSR) and Virtualized Mobile Gateway (VMG): They key takeaway from that set of tests was that Nokia has a set of VNFs that not only passed EANTC's exacting tests, but passed with flying colors across a variety of scenarios. (See Validating Nokia's IP Routing & Mobile Gateway VNFs and EANTC Tests Nokia IP Routing & Mobile Gateway VNFs for Real World Deployment.)

Now the EANTC team has revisited Nokia's labs in Mountain View, California, to test two more of the vendor's VNFs, both of both of which run on Nokia's VSR.

The virtual Broadband Network Gateway (VSR-BNG), which plays an important role in subscriber management and the delivery of multimedia services to residential broadband users, and virtualized Application Assurance (VSR-AA), which performs a number of deep packet inspection (DPI)-related tasks, were both put through their paces to see if they could stand up to the production network performance and scalability standards expected by CSPs.

As you'll see on the following pages -- which provide a detailed explanation of the tests, how they were set up and the outcomes -- the VSR-BNG and VSR-AA met the brief in terms of throughput, subscriber load, redundancy (in multiple potential downtime scenarios) and feature functionality.

The key takeaway is that CSPs can be confident that these VNFs are ready to move out of the lab and proof of concept setup and into the network as part of a next generation, cloud-oriented transformation: Network functions virtualization is ready for prime time.

The following pages tell the story of the multiple tests undertaken by the EANTC team:

Those network diagrams
Your network diagrams are atrocious. Seriously, they hurt my eyes. Please use a decent icon set.

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
