S DN中一种基于多级流表的功能组合方法
A Function Co mposition Method of Software-Defined Network Based on Multiple Tables
摘要
Abstract
Network applications in Software-Defined Network (SDN)are always required to implement several func-tions to meet the network service demands,but how to arrange the function modules running on SDN controller to achieve multiple function packet processing is a problem to be solved.To compose the network functions,we introduced parallel and sequential composition schemes based on multiple tables;secondly,we put forward functional composition algorithms that can adapt with any multiple-table openflow switches;finally,we devised and implemented a Ryu-based control module which is used to do the function composition.Experimental results show that the method can reduce the storage cost and processing delay effectively compared with the existing schemes.关键词
