A service function chain deployment method, device, electronic equipment and storage medium

Abstract

The invention discloses a service function chain deployment method, device, electronic equipment and storage medium, which are used to solve the technical problem that the existing VNF placement method cannot take into account both reliability and overhead cost. The present invention includes: initializing bottom layer network topology information and service function chain SFC request; according to said initialization bottom layer network topology information and said SFC request, taking reliability and overhead cost weighted difference maximization as the optimization goal, establishing a deployment cost optimization model; Solve the deployment cost optimization model according to the preset improved simulated annealing algorithm, generate an SFC deployment plan with an optimal weighted difference; generate an initial path set according to the underlying network topology information and the SFC deployment plan, and start from the initial path set The target path is determined in the path set, and an optimal SFC deployment scheme is output based on the mapping relationship of the preset resource equipment of the target path.

Description

technical field [0001] The present invention relates to the technical field of mobile edge computing, and in particular, to a service function chain deployment method, device, electronic device 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 require the deployment of various specialized network middleware. However, this brings up many problems. For example, the network upgrade requires huge costs, the network framework lacks flexibility, poor manageability, and 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 network function virtualization (NFV), virtual network functions (VNFs) are combined in a certain logical order according ...
