OpenFlow Supports IPv6 Flows

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. Now, newer OpenFlow versions have IPv6 capabilities and more vendors are deploying products that use the newer OpenFlow versions. This article goes over the IPv6 functions within the OpenFlow protocol and describes how these are being used.
