For this post I met up with DartPoints CTO Satya Baddipudi to discuss where best to locate virtual functions, when NFV will hit the mainstream and how a software approach to service chaining can replace the “conga line” of devices. Prayson: Satya, could you start off by telling me a little about your company's role in the NFV transformation? Satya: At DartPoints we had been taking a cautiously optimistic view of the NFV technology, and now we’re moving to be one of the early adopters. Most of our deployments are greenfield, which is a little different from the other ISPs and CSPs. This enables us to be receptive to new technologies and innovations, wherever it ...

As always, PTC in Hawaii was a great event to kick off the year. It looks like 2016 will be a crucial time for software-defined networking (SDN) and network functions virtualization (NFV) and this was reflected in the program for PTC'16. There were three SDN/NFV-focused sessions (compared with only one last year), including the panel discussion that I took part in. It turned out to be a fascinating and very lively roundtable debate chaired by Joe Weinman, author of Cloudonomics and Digital Disciplines. Along with panellists from Ciena and BTI Systems, I discussed the implications of SDN/NFV for cloud and network service providers. Here’s a few of the main points I took from our debate ...

For many years, network engineers had a dream. Their vision was that one day a network's operations and management would be driven by its applications. Today, with software-defined networking (SDN), that dream is finally becoming reality. ADVA Optical Networking recently played a key role in a major European multi-layer multi-vendor SDN field trial that was proof of this. The demonstration highlighted some of the key achievements of the past few months. As well as use cases like traffic optimization and multi-layer re-routing following cable breaks, the most significant breakthrough was the utilization of an SDN architecture in real-world production networks. Juniper Networks and ADVA Optical Networking had already demonstrated packet optical multi-layer coordination at SDN OpenFlow World Congress in Düsseldorf, Germany in October 2015. In that showcase ...

2015 was a big year for network functions virtualization (NFV). In recent months, the technology has made a lot of progress in its journey from the blackboard to real world implementation. We've seen NFV move from theoretical discussion to lab testing and public demonstrations. Now, as it stands ready to take its next step from demo to deployment, here's my forecast for the top five NFV trends in 2016. 1) We’ll See Major Progress in the NFV Technology Lifecycle - Leading communication service providers (CSPs) will start to make more solid commitments to NFV. Those who haven’t already done so will begin to run major projects to explore how NFV can be used to improve network efficiency by reducing hardware diversity and increasing the level of automation. Service providers with existing data centers will favor central hosting of virtualized network functions, while edge NFV will be the entry strategy for CSPs that have focused on connectivity services so far ...
