A load balancing priority method for combining virtualized network functions

Abstract

The present invention belongs to the technical field of computer communication, and in particular relates to a virtualized network function combination method with load balancing priority. The method includes: the control center periodically updates the remaining resources of each network node and the distribution information of network function instances; transform it into a network policy; combine perception information and network policy to select candidate network function instances, and form vectors from large to small according to the remaining resources of the node where they are located; extract the first function instance in each vector Make a combination, calculate the performance parameters of the combination, and judge whether it meets the business request; if the judgment result is "satisfied", then it is determined that the combination provides services, configures the parameters of the selected function instance, and sends the flow table to its The connected SDN switch; if the judgment result is "not satisfied", the contribution degree of each function instance is calculated based on the multidimensional performance parameters of the function instance, and the function instance with the lowest contribution degree is replaced by the next function instance in the vector.

Description

technical field [0001] The invention belongs to the technical field of computer communication, in particular to a virtualized network function combination method with load balancing priority. Background technique [0002] In order to enhance the functionality and security features of the network, a large number of network applications such as firewalls, IDS, and NAT are deployed in the network, and these network applications are generally deployed in the form of dedicated hardware devices. The privacy, closure, and non-scalability of network equipment lead to high management costs, complex management processes, and waste of equipment resources. It is urgent to establish a new network function deployment architecture to achieve flexible, scalable, low-cost, and high-efficiency networks. Function. [0003] Network function virtualization proposes the idea of ​​implementing the above-mentioned network applications in the form of running software on commercial servers, and has ...
