Service function chain deployment method and system based on delay optimization orchestration algorithm

The invention provides a service function chain deployment method and system based on a delay optimization orchestration algorithm, and belongs to the technical field of communication. An index of a maximum schedulable continuous VNF number MSN is introduced, a genetic algorithm is combined, the VNF optimization deployment model is solved, and an optimal current to-be-deployed VNF is obtained; after the MSN value calculated according to the current VNF to be deployed is obtained, the host node with the maximum MSN value is selected as a target host, and MSN hosts behind the current VNF are deployed to the target host until the SFC is deployed completely. According to the method, an SFC arrangement model in a containerized environment is constructed, SFC arrangement is modeled into a multi-objective optimization problem, and the approximation property of network topology on a containerized NFV platform is analyzed; according to the method, each SFC request is processed in a staged decision mode, a physical hos
