Protecting dynamic multicast session in optical networks
- Abstract
Recent advances in wavelength division Multiplexing (WDM) technology are expected to facilitate bandwidth –intensive multicast applications. However, a single fiber (bundle) cut on such a networks can disrupt the transmission of information to several destination nodes on a light tree based multicast session. Thus, it is imperative to protect multicast session. A shared path protection algorithm for dynamic multicast sessions (SPP-DM) is proposed in this paper. It enables a present protection path to share wavelengths with already built protection paths as well as the sharing between working paths. We first study the problem of protecting a single tree, find a link-based approach to protect it, and then extend the approach to the Dynamic case, where multicast connection requests come in sequence. The simulation with the topology of the ARPA Network shows that SPP-DM performs better in blocking probability than the algorithm proposed in [1], called an Optimal path-pair-based shared disjoint paths (OPP-SDP) algorithm, which has been showed in [1] to be more efficient than other existing algorithms.
