Service chain deployment method and device for cloud-side collaborative Internet of Things

Abstract

The invention provides a service chain deployment method and device for a cloud edge collaborative Internet of Things. The method comprises the following steps: obtaining a first construction scheme of a service chain SFC according to a preset arrangement sequence and a preset dependency relationship of VNFs in the SFC, and determining the VNFs with parallel function requirements in the SFC according to the service types of the VNFs, parallel processing is carried out on a part of VNFs in the SFC to form a second construction scheme; merging partial virtual nodes in the second construction schemes of the plurality of different SFCs to obtain a comprehensive construction scheme; and establishing a service chain deployment optimization model of the comprehensive construction scheme, obtaining a deployment scheme of each virtual node and each virtual link in the comprehensive construction scheme according to an optimal solution of the service chain deployment optimization model, and deploying each virtual node and each virtual link on the cloud edge collaborative network according to the deployment scheme. According to the invention, the service chain time delay is reduced, and the quality, reliability and stability of the network are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a service chain deployment method and device for cloud-edge collaborative Internet of Things. Background technique [0002] With the development of 5G and cloud computing, the data on the edge side increases rapidly and needs to be transmitted to the data center network for processing. Although the traditional cloud-centric computing model of the central network can support these services with its powerful computing capabilities and abundant resources, it will cause a huge load on the core network and bring a large end-to-end time to the business. delay. In order to meet this challenge, MEC (Mobile edge computing, mobile edge computing) technology was proposed to reduce the overall delay by providing computing power at the edge of the network. However, the limited resources and computing power of edge servers cannot completely replace the role of cloud computing....
