Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that the embodiments described in the present invention are only the link deployment process in the network slice deployment, not the entire deployment process of the network slice, and the premise of the link deployment is the deployment result of known nodes. According to the embodiments of the present invention, all other embodiments of the present invention realized by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. In the following description, the technologies irrelevant to the present invention are only briefly explained or directly skipped.

[0025] In the existing technology, the network slice link deployment stra...

Abstract

The invention discloses a network slice link deployment method and device. The method comprises the following steps: acquiring a topological structure of a physical infrastructure network; acquiring attributes of VNFs in network slices on physical infrastructure; and selecting the VNFs that need to be mutually connected in the network slices according to the attributes of the VNFs, and calculatingconnection routes between the VNFs based on the maximum forwarding times of routing equipment. The method and device disclosed by the invention has the advantages that during network slice link deployment, both route transmission and loads of links and the routing equipment are considered, so that the technical effects of an overall load balance and reasonably improved network slice service reliability are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for deploying network slicing links. Background technique [0002] With the rapid development of communication technology, in order to meet the differentiated needs of many applications, network slicing, as an emerging solution, enables it to segment multiple isolated end-to-end logical networks in a physical infrastructure. , to provide customized services for different business scenarios. This technical advantage makes network slicing occupy an important position in 5G network technology. [0003] In a 5G communication network based on Software Defined Network (SDN, Software Defined Network) / Network Function Virtualization (NFV, Network Functions Virtualization), how to effectively deploy network slicing is a problem that must be solved before large-scale commercialization of 5G networks. In the process of network slicing deployment, the mapping relationsh...
