Celebrations and Struggles at NFV #8

Celebrations and Struggles at NFV #8

By Ron Breault I’ve attended every ETSI NFV Plenary session since April of 2013 – that’s seven in total – and I’d venture to say that the recently concluded NFV #8 was the most raucous to date! To be fair, this wasn’t just any plenary; this was the session in which the first phase of NFV was formally wrapped up…
RIP OVDK: High-Performance Virtual Switching Available Now in Commercial Telecom Platform

RIP OVDK: High-Performance Virtual Switching Available Now in Commercial Telecom Platform

By Charlie Ashton Intel recently announced that they have discontinued the OVDK virtual switch (SDNCentral article here). This prompted questions from service providers and Telecom Equipment Manufacturers (TEMs) who need high-performance, Carrier Grade vSwitch solutions for deployment in commercial networks as part of their Network Functions Virtualization (NFV) infrastructure. There is life after OVDK and no reason for concern. In…
Gremlin Free Zone

Gremlin Free Zone

By Ron Breault I recently conducted a live demo of our Wind River Titanium Server product during one of SDNCentral's DemoFridays.  This was a great way to reach a wide and highly relevant audience (and save time traveling to several dozen customer sites).  How appropriate too that we were using cloud technologies and wide area networking to show case an…
NFV in Action: Where to see Titanium Server before the end of the year

NFV in Action: Where to see Titanium Server before the end of the year

By Jeff Gowan The telecom industry is eagerly working towards NFV. With NFV, by taking advantage of a virtualized environment, carriers can easily and rapidly introduce new services while reducing costs. At every step, maintaining carrier grade reliability is absolutely essential. Wind River Titanium Server is the industry’s first fully integrated and feature complete NFV software platform, and is the…
How Do We Minimize Downtime in NFV?

How Do We Minimize Downtime in NFV?

By Charlie Ashton At the recent SDN and OpenFlow World Congress in Dusseldorf, I was invited to give a talk about the cost of downtime in telecom networks and how this financial impact might be affected by NFV. This seemed to be a topic of wide interest, at least within the NFV-focused audience at the event. So in this post, I’ll summarize some…
ETSI NFV Proof of Concept #22

ETSI NFV Proof of Concept #22

By Ron Breault I recently returned from a hectic week at the 2014 SDN & OpenFlow World Congress in Düsseldorf, Germany.  This show has grown to become one of the biggest events in the NFV industry, having increased in attendance by over 50% since 2013.  With an impressive 1300 participants registered this year, the show had representatives from most of…
Wanted: Virtual Switching without Compromise

Wanted: Virtual Switching without Compromise

By Charlie Ashton At the recent Intel Developer Forum in San Francisco, there was lots of discussion about the tradeoffs associated with various approaches to virtual switching. In this post, we’ll outline the pros and cons of the most common solutions and show that it’s possible to meet aggressive performance targets without compromising on critical system-level features. Virtual switching is…
What’s the Real Cost of Network Downtime?

What’s the Real Cost of Network Downtime?

By Charlie Ashton When networks go down, even for a brief moment, thousands of dollars are in jeopardy. Can service providers afford sacrificing carrier-grade reliability and risk facing downtime? I've been examining the technical requirements for carrier-grade reliability in telecom networks quite a bit in recent weeks. One recent blog post discussed the differences between "high availability" and "carrier grade," while a subsequent…
How Virtual Switch Performance Improves Service Provider OPEX

How Virtual Switch Performance Improves Service Provider OPEX

By Charlie Ashton This post will explain how increasing the performance of the virtual switch in an NFV platform causes very significant improvements in service provider opex. We’ll show an example that illustrates a 6.7x increase in the number of subscribers supported per server, while explaining how greater improvements are possible in other use cases. When the concepts for network functions virtualization (NFV) were first…
NFV on Mars?!

NFV on Mars?!

By Ron Breault What does Wind River’s network functions virtualization (NFV) platform, the Wind River Carrier Grade Communications Server have in common with NASA’s Mars Rover and Boeing’s 787 Dreamliner? If you guessed “two occurrences of letter R,” you get a point for being quick off the mark, but there’s more…a whole lot more to it than that! The full…
