In this paper, a multi-tree construction algorithm based on overlay service network is proposed, which is tailored toward support of multi-channel live media delivery. The multiple source-specific trees are built to deliver the multiple sources respectively on shared overlay network resources. Unlike the legacy schemes, the construction of trees is not from the view of a single tree, but considering the shared overlay nodes by multiple trees holistically. The relativity of the different tree sessions is well considered. From the simulation results, a better- balanced performance is achieved among different sessions. Moreover, the proposed method makes it possible for the overlay service provider to gain a better control of the multiple sessions, and provides service differentiation on overlay service network.
