Claim 4:
5. 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 SFC parallel problem in step (2) is specifically described as follows:
The serial SFCs which work independently without affecting other VNFs are converted into parallel SFCs; since the VNFs in the SFCs is applied to each data packet flow necessarily according to a specific order, the VNFs form a dependency relationship; the method stipulates that in a case that one VNF fvμ is before another VNF fv+1μ, fv+1μ depends on fvμ, denoted as fvμ<fv+1μ;
to process the data packets in parallel, two functions of copying and merging are required; when one data packet enters, the copying function will copy and send the data packet to the VNFs capable of being processed in parallel; and after the data packet is processed, the copied data packet is merged by the merging function, and the copying and merging of the data packet will cause additional resource consumption and delay.
