A Directed-Multicast Routing Approach with Path Replication in Content Addressable Network

In order to improve the efficiency of routing and resource location under large scale failure of Content Addressable Network, a directed-multicast routing approach is proposed to solve the backtrack problem of the traditional greedy approach. Possessing the advantages of directed routing approach and multicast, this new approach also has an extending coefficient to increase its feasibility. Meanwhile, we explore a new replication approach that we term Path Replication. Combining with Path Replication, the directed-multicast routing approach is more efficient in routing process. The efficiency of directed-multicast routing was proved in the simulations on PlanetSim.
