校园专网中基于SDN的路径选择与带宽保障策略
PATH DETERMINATION AND BANDWIDTH GUARANTEE STRATEGY BASED ON SDN IN CAMPUS NETWORK
摘要
Abstract
Important businesses in private campus network need sufficient bandwidth to guarantee their quality of service.Simply setting port queue ignores the possibility of total bandwidth requirement exceeding the link capacity,and OPPBG(OpenFlow-Based Path-Planning with Bandwidth Guarantee)algorithm cannot distinguish multiple businesses. In view of this, we proposed a path determination and bandwidth guarantee strategy based on SDN(Software Defined Networking).The algorithm first deleted the link that did not meet the bandwidth requirement and then obtained the best path through the path selection process.Finally, the switch port queue was set for each service for scheduling and forwarding along the path.The experimental results showed that the bandwidth requirements of each important business were satisfied.This algorithm effectively improved the service quality of the private network and prevented important services from interfering with existing flow and future flow and improved network performance and robustness.关键词
