BALANCEFLOW:CONTROLLER LOAD BALANCING FOR OPENFLOW NETWORKS
In the discussion about Future Internet,Software-Defined Networking (SDN),enabled by OpenFlow,is currently seen as one of the most promising paradigm.While the availability and scalability concerns rises as a single controller could be alleviated by using replicate or distributed controllers,there lacks a flexible mechanism to allow controller load balancing.This paper proposes BalanceFlow,a controller load balancing architecture for OpenFlow networks.By utilizing CONTROLLER X action extension for OpenFlow switches and cross-controller communication,one of the controllers,called super controller,can flexibly tune the flow-requests handled by each controller,without introducing unacceptable propagation latencies.Experiments based on real topology show that BalanceFlow can adjust the load of each controller dynamically.
