A directional multicast routing algorithm based on path redundancy in content addressable network

Abstract:

To improve the resource positioning rate and routing efficiency in the content addressable network,a directional multicast routing algorithm based on path redundancy is put forward.Integrating the advantages of the directional and broadcasting routing algorithms,the new algorithm employs the extending coefficient to enlarge the dimensions of the CAN logical space.Meanwhile,the positioning efficiency of the new algorithm is increased by combining the directional multicast routing algorithm with the probability path redundancy.The effectiveness of the algorithm is proved in the simulation.
