Precisely Control Routing Convergence by Adjusting Parameters Based on Network State

A large number of technologies have proved the possibility of fast convergence. However the most difficult part is not guarantee the convergence speed but how to control it properly. In this paper, we proposed a scheme to configure parameters of routing protocol based on the real-time network state evaluation. The goal is to adjust the pace of routing convergence according to the different importance of fault network units. We attempt to adjust the pace of routing convergence based on real-time state of network. All basic functions are closely integrated with the network state. The main contribution of our work is to control the convergence speed properly, which is also the biggest difference with other survivability technologies.
