Abstract:

To meet the requirements for the simulation and performance evaluation of multi path inter domain routing protocols, a Click and NS2 based dedicated multi path inter domain routing simulator, named MIRS, is designed and implemented. MIRS is built by embedding the Click modular software router into the NS2 simulator. The source code with MIRS may run under a simulator as well as on existent actual systems with minor modifications, thereby efficiently shortening the period of experiment and evaluation. Moreover, MIRS can improve the accuracy of simulations by accurately describing the traffic forwarding behavior of multi path routers.  Simulation was conducted with a network topology as well as the real network topology of Shandong University respectively. The results not only indicate that multi path routing has a greater advantage in improving network performance than singlepath routing, but also show that MIRS is a useful and effective tool for evaluating multipath routing protocols.

Key words: multi-path inter-domain routing； simulator； Click； NS2
