Abstract
Disclosed is a method for SFC deployment and migration based on VNF-dependent components, which pertains to the field of communication technologies. The method jointly optimizes SFC deployment and migration policies with consideration of VNF-dependent component migration, and is used for addressing mobile user service provisioning issues. The method is based on a mobile terminal user initiating a service request information to an SDN controller, which analyzes, based on the service request information, user demand types and resource requirements thereof, including bandwidth resources, computing resources, storage resources, delay requirements, and the like, and the SDN controller, in combination with a network topology structure, resource status of an edge server, and network operation conditions, optimizes the deployment and migration of the SFCs using deep reinforcement learning technology. In the present disclosure, the interactions among VNF-dependent component migration, SFC deployment, and SFC migration decisions are comprehensively considered to efficiently provide mobile services.
