摘    要: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.

关 键 词:开放最短路径优先  链路状态广播刷新机制  流量控制  流量调节  控制功能  刷新机制  control  function  traffic  意义  指导  路由协议  链路状态  算法  预期  调整  变化  发生  网络状况  显示  试验  模拟  避免拥塞  递减

Abstract: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 mecha- nism 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.
Keywords:OSPF(open shortest path first)  LSA(link state advertisement))refresh mechanism  traffic control
