Software-Defined Networking (SDN) is the HOT topic in the IT industry. There’s a new meetup group dedicated to the topic of SDN and Network Virtualization. Nicknamed “NVIRTERS”, they offer a great resource for learning more about SDN and networking in general. Tech talks, workshops, hackathons – and more!
Software-Defined Networking. SDN. It’s the buzz right now, promising a new model for networking that decouples the embedded value in networking devices and allows new capabilities to be easily deployed. There are a lot of things that have to happen to make SDN a reality. First, current networking product vendors need to embrace this new model. While they will never fully open their boxes and allow the control plane to be fully decoupled, it’s a given that SDN is going to force fundamental changes. Second, merchant silicon (not necessarily “commodity” hardware) is needed to allow more programmability of physical network devices. Third, standards for both northbound and southbound interfaces need to mature to allow reusability of networking applications and services. And finally, scalable and resilient applications need to be developed. Sounds like a pretty tall order… but the tide has shifted and the industry is moving to SDN. So everybody needs to get ready for new business and operational models that can take advantage of the underlying technological advancements. Read all »
Software-Defined Networking (SDN) is a shockwave through the networking industry. Robert Keahey recently presented key SDN trends and capabilities at the IEEE Smart Tech: Metro Area Workshop in Santa Clara, CA, and again at the IEEE Consultants’ Network of Silicon Valley.
Cloud computing is one of the most disruptive business and technology innovations we’ve seen over the past decade. Second only, maybe, to virtualization. Interestingly enough, both of these innovations have their origins rooted in technologies that surfaced much earlier than we think, with virtualization dating all the way back to the 80’s, and cloud computing growing out of the utility infrastructure model that entered the scene in the early 2000’s. So what have we learned from this past experience? Read all »
