Abstract

The present invention provides a multi-type VNF deployment method based on betweenness centrality, which relates to the technical field of communication, and includes: first obtaining a plurality of virtual network function VNFs to be deployed, and performing all VNFs according to the traffic change rate of each VNF Sort in descending order to obtain the VNF sequence; then use the preset betweenness centrality formula to calculate the betweenness centrality of each server node, and sort all the server nodes in descending order according to the betweenness centrality to obtain the server node sequence; finally follow the preset deployment method Deploy all VNFs to each server node. In the present invention, by deploying the VNF with a large traffic change rate on the server node with high betweenness centrality, the VNF with a large traffic change rate can be closer to the source nodes of different service flows, so that the service flow can be kept low in the network. Stream speed transmission, so as to achieve the purpose of reducing the bandwidth occupation of multiple service streams.

Description

Technical field [0001] The present invention relates to the field of communication technologies, in particular, to a plurality of VNF deployment methods based on intermediary center. Background technique [0002] VNF (Virtual Network Function, Virtual Network Function) Deployment refers to the logical network service diagram described based on SFC (ServiceFunction Chain, Business Chain), using a specific deployment algorithm, or using the characteristics of the logical network service diagram and the underlying physical network diagram Map the logical network service is valid to the bottom network. The existing VNF deployment methods mainly include the following categories: random deployment methods, shortest SFC path deployment methods, and VNF deployment algorithms based on specific targets. [0003] Due to the three types of VNF deployment methods, the random deployment method and the shortest SFC path deployment method, the bandwidth changes from VNF processing traffic are ig...
