VMware wants to be the VMware of Networking « IT 2.0
By Massimo, on April 17th, 2012 There have been a lot of discussions lately about SDN (Software Defined Networking). Arguably SDN may mean a lot of different things to a lot of different people. If you ask the like of Facebook, Google and academic researchers they will probably tell you that SDN is all about gaining full visibility (and control) on how packets flow on the network. People and organizations that are closer to the commercial world may tell you that SDN is all about creating an abstraction layer (virtualization anyone?) in the network – from layer 2 all the way to layer 7. I’d like to focus on the latter definition of SDN. A few weeks ago Cisco’s Lauren Cooney asked a question on twitter on the line of “how would you define SDN?”. Look at the picture. SDN purists may very well argue that this PDF was not including important aspects of SDN such as self-service capabilities and a proper API to access these functionalities. Massimo.
