摘要

软件定义网络（SDN）通过转发与控制分离，借助控制面的集中化实现网络的灵活性和开放性.控制器部署是SDN部署运行的基础和前提.针对层次型多中心SDN的控制器部署问题，该文采用多层

路划分方法实现大规模SDN网络的区域划分，将传统的SDN多控制器直接部署转化为区域划分和域内控制器部署，同时通过减少图划分的域间割边数以降低SDN跨域流数量以提高流表构建效率.通过实验验证，较其他传统方法，该文提出的层次型多中心控制器部署方法可有效减少网络通信代价，降低流表构建代价.

Abstract

Software defined networking(SDN) is a style of computer networking that separates the control plane from the data plane

shifting the control plane to a centralized controller in order to achieve network flexibility and openness.The controller placement is a key prerequisite to successful SDN.The current study examines the hierarchically distributed control plane controller placement problem

utilizing a multi-level

-way switch partition algorithm to divide large scale network topology.We also fix the traditional SDN controller placement problem

changing zoning and intra-domain controller placement by reducing the edge-cut in order to lower the number of inter-domain flows.Simulation results show that the multi-level

-way switch partition algorithm can effectively re

duce control flow overhead and flow set-up time

compared with the other traditional algorithms.
