  • OpenFlow Supports IPv6 Flows

    By Scott Hogg | 01 August, 2014 10:25

    OpenFlow is a Software-Defined Networking (SDN) protocol used for southbound communications from an SDN controller to and from a network device. OpenFlow is the protocol used to inform the topology of network switches on which flows should be added to their flow tables and advise switches how they should handle traffic flows that are not in the current flow tables. Initially, OpenFlow did not have any definition for handling IPv6 communications.

This article goes over the IPv6 functions within the OpenFlow protocol and describes how these are being used.
