摘要
针对网络效率低、移植性和可控性差,设计一种替换策略决定交换机的替换顺序,并利用软件定义网络(SDN)技术将传统交换机更换为支持OpenFlow(OF)协议的交换机,分流数据流量,降低了网络拥塞。仿真结果表明,与随机替换策略相比,该策略提高了可控链路数量和节省了链路空间。
A replacement method is designed to solve the problem of inefficiency,lacking of transplanting and uncontrollable of the network by using software designed network（SDN）.The traditional switch is transformed into OpenFlow switch.Thus it ensures the full utilization of link and reduces the possibility of congestion.The simulation result shows that compared with the random method,the number of alternative path is increased and the link capacity is saved.
