METHOD FOR SELECTING LEADER CONTROLLER NODE IN DECENTRALIZED SOFTWARE-DEFINED NETWORK

摘要

The present invention relates to a method for selecting a leader controller in a distributed software defined network, the method comprising: calculating a stability value for the mobility of each of a plurality of controller nodes; generating a two-layer virtual loop in and out of a plurality of domains based on the calculated stability value; and synchronizing information about each node in and out of a plurality of domains based on the two-layer virtual loop.
