Abstract

The invention provides a service function chain arrangement method for operation-level function parallelization and adaptive resource allocation, which relates to the technical field of communication and comprises the following steps: acquiring a service function chain SFC topology of a target source server node in a virtualized network to be optimized; performing function-level parallel processing and operation-level parallel processing on network functions in the SFC topology based on a preset virtual network function parallelism relation table to obtain a recombined SFC topology; and determining a corresponding resource allocation strategy for the target source server node based on the recombined SFC topology and a preset adaptive resource allocation algorithm. According to the method, from the perspective of the SFC, the network functions in the SFC topology are subjected to function-level parallelism and operation-level parallelism according to the preset virtual network function parallelism relation table, and compared with the traditional serial SFC topology, the recombined SFC topology can effectively reduce the total delay loss and improve the throughput.

Description

Technical field [0001] The present invention relates to the technical field of communications, in particular, to a service function chain burying method for operational stage function parallel and adaptive resource allocation. Background technique [0002] In the prior art, the Service Function Chain, SFC) is combined with network function virtualization, NFV. Virtual Network Function, VNF) is used as a network function instance node in SFC. Really, the flexibility of service functions, the flexibility scheduling of the transmission path, also makes the service type more and more fast updates to the current user needs. [0003] However, the NFV improves SFC flexibility while also brings performance weakening. The performance of the existing VNF is generally weaker than proprietary hardware, producing more time delay, and the time delay consumption of VNF will also The length of the SFC is raised, and it has a great impact on the overall performance of the system, which is difficu...
