This paper proposes a set of novel distributed algorithms on top of m-D irregular mesh overlay to achieve the short delay and low network resource consumption end host multicast services. Our end host multicast fully utilizes the advantages of m-D irregular mesh to construct a two-layer architecture. Compared to previous approaches, the novelty and contribution of our end host multicast include: 1. cluster formation that partitions the group members into different clusters in the lower layer; 2. cluster core selection that selects a core who has the minimum sum of overlay hops to all other cluster members for each cluster ; 3. weighted shortest path tree construction that constructs the shortest multicast trees with the minimum number of paths to propagate the multicast traffic; 4. distributed multicast routing directs the multicast messages to be efficiently distributed along the two-layer multicast architecture in parallel without a global control. Simulation results show that our end host multicast can distributively achieves the short delay and low network resource consumption multicast services as compared with some well-know end host multicast systems.
