The modern data center is going through an unprecedented transformation, as customers attempt to deploy new applications in a highly virtualized, cloud-based environment.  What is clear is that traditional networks are not suited to handling the traffic patterns and volumes created by these more agile cloud-computing environments.  What we also know is that centralizing network intelligence through software-defined networking (SDN) has emerged as the preferred approach to solving the Big Data / network bottleneck conundrum.

Today the IBM System Networking released a series of technical papers that further support and underline industry standards unfolding around SDN and OpenFlow, a protocol developed at Stanford University offering an open-standards approach to SDN. 

Both IBM and NEC are strong supporters of industry standards within the data center network, and we’re pleased to endorse the series of technical briefs known as Open Datacenter Interoperable Network (ODIN).  In addition to OpenFlow, the IBM papers will cover other standards such as IEEE 802.1Qbg and FCoE. 

Casimer DeCusatis, Ph.D., an IBM Distinguished Engineer, wrote the ODIN on SDN architecture.  In it, he points to the logical view of the SDN architecture, using a diagram developed by members of the Open Networking Foundation (ONF).  NEC was a founding member at ONF, and participated in developing this view of SDN.  We strongly support IBM in their discussions around this standardized network architecture, depicted here. 

You can read the full texts of IBM ODIN papers at on the IBM System Networking website.   You can also follow Casimer DeCusatis on his blog  or on Twitter for further updates.  And, of course, you can read and learn more about ProgrammableFlow at www.necam.com/pflow.  In January, NEC announced its SDN collaboration with IBM.
