OpenFlow Supports IPv6 Flows

Scott Hogg | Aug. 1, 2014
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.

Learning More:

A great place to learn more about OpenFlow is at the Open Networking Summit.  This year's event was in March 2014 and next year's event is June 15-18, 2015 in Santa Clara, CA, USA.  However, if your organization is not a member of the Open Networking Foundation (ONF), then you might not have access.

Network World also puts on their Open Network Exchange (ONX) Conference.  This year's event was in May in Chicago.  Hopefully there is another event like this next year.

If you want to learn more about IPv6 and how it is used with OpenFlow, SDN, cloud systems, security, the Internet of Things (IoT), then you should consider attending the 7th annual 2014 North American IPv6 Summit.  This premier IPv6 event is being held in Denver, CO, USA September 23-25.  This even is put on by the Rocky Mountain IPv6 Task Force (RMv6TF) and the other IPv6 task forces in North America.  More information on this year's conference and past materials on IPv6 is available for free at
