Abstract
In this paper, we propose the alternative LSP allocation for MPLS networks required more confidence. In the first place, we must classify the user traffics by the QoS parameter. We assigned altermative LSPs on realtime traffics and then allocated alternative LSPs of non-realtime traffics. The proposed algorithm can provide more confidential alternative LSP by priority method for relatively high cost realtime traffic error. And the proposed algorithm can improve the shortage of network resources what is occured by using a few links when altermative LSPs are setup. The validity of the proposed algorithm has been justified in performance by analysis through simulation results using the program tool and comparison with conventional methods. Also, that improves 9% more than existing method in the recovery ratio-one is 89%, the other is 98%, respectively.
