Abstract

This paper proposed an optimized mapping algorithm for service function chain based on improved sparrow search algorithm to realize the low-cost and efficient deployment of service chain in 5G network scenario. It coded the composition schemes and the mapping schemes of service requests together by a double-layer coding method in the mapping process, and then used an improved sparrow search algorithm to obtain the service function chain deployment scheme of the request and calculated the mapping weight. When there were multiple request types in the same time slice, it sorted all service function chains according to the mapping weight, and mapped the requests that had high weight as priority, so as to reduce the delay overhead and improve the utilization of node computing resources and link resources. Simulation results show that the algorithm can effectively reduce deployment overhead and improve resource utilization.
