摘要: 提出了一种基于OSPF路由协议的拥塞控制策略。利用OSPF协议的链路状态更新报文(LSA)中的空闲位,增加路由器的拥塞状态和流量状态的描述,随LSA报文的传播将路由器的拥塞情况告知其他路由器,利用OSPF的快速收敛及时得知网络拥塞状况并进行早期的拥塞避免。仿真模拟表明,该方案能够控制网络拥塞,减小延迟,达到网络负载平衡。

Abstract: A design method of congestion control strategy is presented based on OSPF protocol. Making use of the free bits of link state advertisements of OSPF protocol, it gives notify other router about the congestion status and traffic status to avoid network congestion. It utilizes fast convergence of OSPF to know network congestion status and avoids congestion early. The simulation indicates that the method can control network congestion and reduce delay for getting network load balancing.
