Embodiment Construction
[0054]The streaming media server only needs to send data out, so it only needs to deploy the sending management module, while other nodes need to receive data and send data to downstream sub-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, and coordinates each parent node to jointly provide streaming media data for the child node.
[0055] In each round, the sending management module sends the data assigned to it in a GOP for each child node in turn, and piggybacks the priority MAP and data possession status MAP in the first packet of each GOP. After sending a GOP data for each child node, receive whether there is a new message, these messages include "new child node join message", "exit channel message" and "reallocate transmission ratio message" and so o...
