Example Embodiment
[0054]The streaming media server only needs to send data to the outside, so only the sending management module needs to be deployed, while other nodes need to receive data and send data to the downstream child nodes, so both the sending management module and the receiving management module need to be deployed. The receiving management module deployed on the child node acts as a scheduler, and sends a scheduling command to the sending management module deployed on the parent node, coordinating each parent node to jointly provide streaming media data for the child node.
[0055] In each round, the sending management module sends the data allocated to the transmission in a GOP to each child node in turn, and piggybacks the priority MAP and the data ownership MAP in the first packet of each GOP. After sending a GOP data for each child node, receive whether there are new messages, these messages include "new child node join message", "exit channel message" and "redistribute transmis...
