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.
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).
OF-DPA’s design, which comes with complementary software and an API library, is meant to enable network virtualization use cases on top of Broadcom’sStrataXGS line of Ethernet switches.
What is OpenFlow? OpenFlow is a programmable network protocol designed to manage and direct traffic among routers and switches from various vendors.
