SND APPARATUS AND METHOD FOR SWITCH MIGRATION ACHIEVING BALANCED LOAD DISTRIBUTION IN DISTRIBUTED SDN CONTROLLER

摘要

Disclosed are a switch migration apparatus and method for load balancing of a distributed SDN controller, and a switch migration method for load balancing of a distributed SDN controller according to an embodiment of the present application includes (a) a plurality of controllers and a plurality of switches Defining the structure of a reinforcement learning-based model for establishing a switch migration policy for a distributed software-defined networking (SDN) system, (b) migrating at least one of the plurality of switches to the plurality of controllers Learning the reinforcement learning-based model based on the change information of the load of each of the plurality of controllers, and (c) based on the reinforcement learning-based model, the switch so that the load of each of the plurality of controllers is evenly distributed It may include determining a migration policy.
