具有流量控制功能的OSPF-SA刷新机制

OSPF-LSA refresh mechanism with traffic control function

分析几种改进的刷新机制,在随机刷新机制的基础上提出流控随机刷新机制。该机制采用慢启动、加速递减等技术对刷新时发送的LSA数量进行控制,以达到根据网络流量调节LSA发送数量、避免拥塞的目的。经模拟实试验显示,当网络状况发生变化时,LSA的发送数量也随之进行调整,达到了预期目的。该算法对于其他链路状态路由协议也具有一定的指导意义。

This paper analyzed these refresh mechanisms, which pointed that the lack of traffic control. The number of sending LSA was not adjusted following the traffic of network ,which resulted in network congestion. Put forward a new refresh mechanism based randomized refresh, which used the technology of slow-start, multiplicative decrease and congestion avoidance for control the LSA traffic. Tests show that , when the state of netwotk is changed , the number of LSA is changed following by it. The way can be used in other link state route protocol, such as IS-IS.
