Abstract :
In order to guarantee the reliable real-time video transmission of overlay multicast network (OMN), a layered multicast tree with three-level is proposed based on NICE protocol to manage multicast service nodes. This solution can improve the data-transmitting efficiency, and minimize the redundant packets in OMN. Also, for the reliable video transmission in bandwidth-limited links of OMN, a QoS algorithm is analyzed by discarding the redundant frames of the video sequences according to the detected network condition. Finally, the performance test verifies the validity of proposed layered multicast tree for reliable video transmission.
