In an OpenFlow network, the various control plane functions of an L2 switch — Spanning Tree Protocol, MAC address learning, etc. — are determined by server software rather than switch firmware.

An SDN research paper points toward what could become OpenFlow 2.0, a protocol that's given more leeway for changing the underlying switches. OpenFlow 2.0 Could Bring New Flexibility to Switches - SDx ...

An OpenFlow 1.2 compliant switch could match on IP protocol number (Ethernet type 0x86dd = IPv6), IPv6 source/destination address, traffic class, flow label, and ICMPv6 types/codes.

Create a reference LibOF, which provides a reference implementation of each version of the OpenFlow protocol that was usable in clients (switches & vSwitches) and servers (controllers & applications).

The combination of open source software and commodity hardware holds the potential for unprecedented efficiency and operational agility but, despite the success of Web-scale giants like Google and Fac ...

Controllers talk to the switches via the OpenFlow protocol and impose policies on flows. The controller could set up paths through the network optimized for specific characteristics, such as speed ...
