Problems solved by technology

[0003] The current business chain resource scheduling algorithms include Round Robin (polling), Least Load (minimum load) and Random (random), which are generally relatively simple and do not fully use resources. The foldback problem causes a waste of link bandwidth resources between servers

Abstract

The invention discloses a service chain resource scheduling method and device. The method includes: obtaining service chain requirement information of the user, wherein the service chain requirement information includes required function network elements and the passing order of required function network elements; determining all feasible paths according to the passing sequence of required function network elements; obtaining all feasible paths The length of the path and the number of users received by the path; according to the path length of all feasible paths and the number of users received by the path, select the user's business chain path from all feasible paths. By considering multiple resource optimizations, the present invention optimizes the use of the three resources of virtual machine CPU, virtual machine memory, and inter-server link bandwidth, and performs load balancing from the perspective of the entire path, thereby realizing a better service chain Path Selection.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a service chain resource scheduling method and device. Background technique [0002] The service chain is a hot application scenario of NFV (Network Function Virtualization, network function virtualization) technology. At present, the business chain networking mode is relatively flexible - there are serial, star and hybrid. Due to the strong correlation between service chain deployment and topology, different networking methods will lead to different service chain deployment methods. Service chain resource scheduling involves many factors: whether the functional network element is preset in advance or the configuration is temporarily triggered by the customer; when multiple devices run the same functional network element, which device should be selected to serve the user, etc. [0003] The current business chain resource scheduling algorithms include Round Robin (polling), Lea...
