What is SDN? I hear so much about it!December 10, 2012
There has been a lot of buzz of a new concept emerging in the network community– software defined networking (SDN). SDN is glamorized as the network’s latest push towards a more streamlined and cost-efficient solution compared to the physical infrastructure currently dominating the floors of IT departments. Promoters are trumpeting this advancement as an innovation marvel; much like virtualization was to servers. In fact, a key component of SDN is bringing networks to a virtual environment. Despite the hype of SDN giving it much notability, many are still confused about the underlying concept of SDN, the possible complications, and the business value of having an SDN network.

SDN is essentially a network architecture where the management, mapping, and control of traffic flow is removed from network devices, and centralized in the network. This separation is said to increase performance, network visibility, and simplicity given it is constructed correctly. However, given SDN’s infancy, a sufficient number of use cases and proof-of-concepts have yet to emerge in the SDN space, leaving organizations wondering if there is any revenue generating or cost saving opportunities. How can they make a sound decision on SDN? It may be too early to make a final decision, but they can start crafting the case and investigate the early movers in the SDN space.
Be prepared to see a shift in networking paradigms because of SDN: hardware to software, physical to virtual, propriety to commodity. Naturally, this will throw off traditional networking staff from their game. But, do not worry, current SDN solutions are still in “Version 1” and future versions may see solutions become friendlier to traditional network practices and concepts. With the attention it is getting from the media and established network leaders, SDN technologies will likely (and hopefully) evolve to mainstream deployment states.
Realize SDN is here. Understand where it came from and how it can help your business. Remember to wait for the SDN space to settle and mature before implementing SDN in your organization. After all, you wouldn’t want your child driving your multi-million dollar car.This entry was posted in Infrastructure, What's New in Research and tagged abstraction, API, Application, architecture, Brocade, Cariden, cisco, commoditization, control plane, controller, data plane, DDoS, decouple, hp, ibm, Infrastructure, interoperability, Juniper, layer 2, layer 3, microsoft, network, network architect, Open Networking Foundation, OpenFlow, OSI, physical, router, SDN, software defined networking, stack, standards, switch, traffic flow, utilization, virtual, virtualization, VMWare.
