Abstract:

In order to solve the problems which may be arised when the routing policy of control plane is updated in in-band mode, an update mechanism based on the destination oriented routing was proposed. The mechanism divides the update policy into subclasses based on the different destinations, and also separates the uplink routing from downlink routing based on the destination. A unified update algorithm was presented for the updating of both uplink and downlink of controlling traffic. Experiment shows that the proposed mechanism shows more efficient both in the computation time and in updating time, but some extra flow entries may be needed.

Key words: software defined networking, in-band control, network policy update, network management
