Successor based Flow Failover in Open Flow Networks

The failure of links in software defined networks based on Open Flow will result in the need to converge on a new topology which will be the same at layer 2 or 3 since open flow seems to merge the control and data planes resulting in unified logical topologies. Since Open Flow utilizes flow tables the concept of feasible successors can be applied to flow tables by inserting alternate paths as less preferred flow entries. The use of successor routes will result in no need to contact a controller on link failures.
