Software defined networking (SDN) is taking the IT industry by storm and is proving to be a very intriguing addition to the networking world. The technology first caught our attention nearly a year ago when companies like VMware and Cisco started acquiring companies like Nicira and Insieme for millions and even billions of dollars as they set foot into the SDN race. We figured if VMware was willing to invest billions to get into the SDN field then it must be worth taking a look at so we’ve been keeping tabs on the SDN field ever since.
Software defined networking is an emerging paradigm in computer networking that allows a logically centralized software program to control the behavior of an entire network. A network administrator can shape traffic from a centralized control console without having to touch individual switches. This control makes it possible for operators to specify more complex tasks that involve integrating many disjoint network functions (e.g., security, resource control, prioritization) into a single control framework, allowing network operators to create more sophisticated policies, and making network configurations easier to configure, manage, troubleshoot, and debug. Essentially, this allows the administrator to use less expensive, commodity switches and have more control over network traffic flow than ever before.
