Overlay multicast tree is widely used to support large-scale real-time multimedia applications. The scalability and the robustness are two key issues in the overlay structure design. In this paper, we propose a Degree pre-reserved hierarchical tree for multimedia multicast, called DTree. It organizes the overlay tree in two hierarchies, and combines application-level multicast with IP multicast to achieve a low delay data delivery. A Degree pre-reserved mechanism is designed in DTree, which greatly shortens the time to resume the data flow, and achieve a fast recovery. Our simulation results show that DTree has a better delivery performance, compared with other overlay tree. It is quite responsive to the changes in the tree, and almost 3 times faster than other recovery strategies in some cases.
