摘要:

在OSPF网络中提出一种基于本地的路由震荡避免机制,该机制通过分析网络当前状态的变化,自适应地调节Hello定时器的值,从而大大减少了链路震荡引起的路由震荡。通过SSFNET仿真验证了本机制不仅比现有基于全网的其他机制占用了更少的网络资源,而且增加了网络的稳定性和可靠性。

Abstract:

A dynamic adaptive route flap suppression mechanism based on OSPF network was proposed. This algorithm tuned the hello timer locally according the changes of network state and eliminated route flap which was caused by link flap. SSFNET establishes an analytical model to investigate that our approach not only achieves better performance and consumes less resources than network-wide methods, but also improves network stability and reliability.

Key words: link flap, route flap, network stability, Hello timer
