Classification: CPC H  G  Y | IPC G  H

Claim 1:
2. The efficient parallelization and deployment method of a multi-objective service function chain based on a CPU+DPU platform according to claim 1, wherein the heterogeneous computing architecture in step (1) is composed of an orchestrator and a server, the orchestrator comprises an SFC deployment algorithm module, a resource management module and a driver module;
the server comprises a CPU, a DPU and a bus for connecting the CPU and the DPU;
the orchestrator is responsible for managing and deploying the arrived SFC, and the server composed of a heterogeneous computing structure is responsible for sequentially processing VNFs in different SFCs according to the deployment strategy conveyed by the orchestrator; wherein a specific task of the orchestrator comprises: receiving an SFC request from a network operator, and running the SFC deployment algorithm to determine which SFCs are accepted and how to place these SFCs; and
for different situations of different requests, the method respectively invokes the parallel strategy, the VNF topological order strategy and the DPU processing strategy so as to obtain an optimal deployment scheme of each request, then a resource management module is invoked to manage resources, and finally, a driver module is invoked to transmit the deployment scheme to a server for placement, and the server completes the deployment of the SFC by using the CPU or the DPU respectively according to the deployment scheme.
