and receiving an open flow instruction, determining a corresponding server and an open flow port on the server based on a channel ID in the open flow instruction, and storing the mapping relation among the channel ID, a server IP of the server and open flow port information of the open flow port to the media information management module.
Specifically, before the packet is grabbed by the media stream data, an open stream instruction is received, wherein the open stream instruction includes two conditions, and in one condition, the open stream instruction is submitted by an application user, and a channel corresponding to the open stream instruction is in an open stream state when the packet is grabbed by the packet grabbing user; in another case, the packet-capturing user submits the packet-capturing instruction, that is, when the packet-capturing user needs to capture the packet, the channel needing to capture the packet is found to be in a non-open state, and at this time, the packet-capturing user needs to submit the packet-capturing instruction so that the channel needing to capture the packet is in an open state.
It will be appreciated that there may be one or more streaming servers. The streaming command generally includes a channel ID, after receiving the streaming command, in a case that there are multiple streaming servers, the channel ID in the streaming command needs to be matched with a corresponding server and an streaming port on the server for the channel based on a load condition of the server, and after the server and the streaming port are matched, a mapping relationship among the channel ID, a server IP of the matched server and streaming port information of the matched streaming port is stored in the media information management module.
