Abstract

The present invention provides a service function chain orchestration method for operation-level function parallelism and self-adaptive resource allocation, which relates to the technical field of communication, including: obtaining the service function chain SFC topology of the target source server node in the virtualized network to be optimized; Set up the virtual network function parallelism relational table, perform function-level parallel processing and operation-level parallel processing on the network functions in the SFC topology, and obtain the reorganized SFC topology; based on the reorganized SFC topology and the preset adaptive resource allocation algorithm, Determine the corresponding resource allocation strategy for the target source server node. The method of the present invention starts from the perspective of SFC, and according to the preset virtual network function parallelism relationship table, the network functions in the SFC topology are parallelized at the function level and at the operation level, and the reorganized SFC topology is compared with the traditional serial SFC topology. The ratio can effectively reduce the total delay loss and improve throughput.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a service function chain orchestration method for operation-level function parallelism and self-adaptive resource allocation. Background technique [0002] In the existing technology, the service function chain (Service Function Chain, SFC) is combined with the network function virtualization (Network Functions Virtualization, NFV) technology, and the virtual network function (Virtual Network Function, VNF) is used as the network function instance node in the SFC , realizing flexible deployment of service functions, flexible scheduling of transmission paths, and also making service types more diverse, adapting to the rapid update of current user needs. [0003] However, while NFV improves the flexibility of SFC, it also reduces performance. The processing performance of existing VNFs is generally weaker than that of proprietary hardware, resulting in more delay loss, and th...
