Label diversion protocol (LDP) is a signal controlling protocol based on the multiple protocol label exchanging system. How to perform path switching is a key issue in the extended LDP protocol(includes p2mp-ldp and mp2mp-ldp). In the case of route flapping, Path switching may cause unnecessary waste of resources. The resource loss rate can be used as an important indicator in many network protocols.Therefore, this paper firstly uses the extended LDP protocol to perform path switching scenarios on route flapping, then abstracts the path switching strategy into a generic modell, exploring the resource loss rate caused by the path switching strategy on the general model.Then,A delay switching strategy is proposed on the general model to prove the feasibility of the delay switching strategy by reducing the resource loss rate. At last, this paper compare normal switching and delayed switching strategies, prove the practicability of the technology through the application on the quagga platform. The delay switching strategy presented in this paper is not only applicable to the LDP protocol, but also to other complex network protocols. |
