Aiming at the problems of heterogeneity and degree constraint of node in application layer multicast,this paper proposes a resource uniform distribution scheme based on multiple description coding.The uniform distribution of sub-descriptions among nodes is achieved with distributed algorithm in terms of the cited time and the numbers of copy.The request set is acquired by weighted selection algorithm,then the load of nodes is balanced.Simulation results demonstrate that the scheme can lower the impact of nodes departure,and it has high scalability and robustness.
