What is OpenFlow? OpenFlow is a programmable network protocol designed to manage and direct traffic among routers and switches from various vendors. It separates the programming of routers and ...

SDN has great potential, but OpenFlow was initially limited by its dependence on expensive memory devices. New ASICs have changed all that ...

With a new industry organization to promote it, routing protocol OpenFlow is about to give users unprecedented ease of control over the way their networks operate.

So what is OpenFlow? In 1984, a team of engineers from Phoenix Technologies worked to replicate the BIOS of the IBM Personal Computer. The result was the PC clone, which commoditized and opened ...

Impact of TCAMs on SDN and OpenFlow performance is critical and we introduce critical TCAM concepts that every SDN practitioner must know.

An OpenFlow-like approach to networking was not really possible until recently, not just because the idea is novel, but because network hardware was not capable enough to handle traffic in this way.

Exploring the concept called the "OpenFlow Microcontroller" where an OpenFlow controller runs in its own VM, isolated from embedded software.

2011 has been an exciting year for Openflow and software defined networking (SDN). Continuing my informal series on Openflow, I recently got the chance to have a conversation with Nicira CTO ...

Some say OpenFlow and software-defined networking are more useful to huge data center-driven companies and network operators than to the enterprise As most participants at the inaugural Open ...
