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
