Abstract
Multiple SDN controllers architecture has been proposed to improve scalability and to avoid single point of failure. In order to resolve consistent network state among SDN multi-controllers, an efficient consensus mechanism to synchronize the control state of each controller is required. Raft is a consensus algorithm used in the OpenDayLight (ODL) Clustering. However, Raft algorithm may suffer from the leader election timeout and the system loading may fall on a certain controller. Thus, we propose a High Performance Paxos-based Consensus algorithm (HPPC) and implement it in the ODL Clustering to maintain a consistent global network state. The proposed HPPC simplifies the original Paxos protocols and guarantees that execution among interference commands when committing the client requests simultaneously. Since HPPC has no leader and every controller can commit requests concurrently, it has lower average consensus time than Raft. Meanwhile, experiment results show that HPPC is 25.2% faster at retrieving data and 66.3% faster at storing data via REST API comparing with Raft.
