Service function chain deployment method and device, electronic equipment and storage medium

Abstract

The invention discloses a service function chain deployment method and device, electronic equipment and a storage medium, which are used for solving the technical problem that reliability and overhead cost cannot be considered at the same time in the existing VNF placement method. The method comprises the following steps: initializing bottom-layer network topology information and a service function chain SFC request; establishing a deployment cost optimization model by taking reliability and overhead cost weighted difference maximization as an optimization target according to the initialized underlying network topology information and the SFC request; solving the deployment cost optimization model according to a preset improved simulated annealing algorithm, and generating an SFC deployment scheme with an optimal weighted difference; and generating an initial path set according to the bottom-layer network topology information and the SFC deployment scheme, determining a target path from the initial path set, and outputting an optimal SFC deployment scheme based on a mapping relationship of preset resource equipment of the target path.

Description

technical field [0001] The present invention relates to the technical field of mobile edge computing, in particular to a service function chain deployment method, device, electronic equipment and storage medium. Background technique [0002] Current mobile edge computing networks have certain limitations. Network operators need to use dedicated network equipment to provide different network access, routing, and computing functions. Therefore, most existing networks need to deploy various specialized network middleware. However, this poses many problems. For example, network upgrades require huge costs, the network framework lacks flexibility, poor manageability, poor scalability, etc., which may not meet the requirements of future high-speed communication and low-latency mobile edge computing. In a network environment based on virtual function virtualization (NFV), virtual network functions (virtual network function, VNF) are combined in a certain logical order according ...
