Abstract

To obtain the partial information of network's resources, which indicates what fraction of each link's bandwidth, is currently used by working paths, and is used by protection paths, is feasible in IP over WDM networks using Multi-Protocol Label Switching (MPLS) technology. Based upon this partial information scenario, this paper proposes a new integrated dynamic routing algorithm of path-based protection design for IP over WDM networks. For working paths selection, the algorithm makes a tradeoff between the routing costs and the corresponding routing path length. While for protection paths, a tradeoff between the sharing of the protection paths and the associated routing path length is made. We find that the developed routing scheme is beneficial to achieve a good link load balancing. Simulation results show that the developed algorithm performs well in terms of performance metrics such as the number of rejected requests and the network link load balancing.
