Abstract:
A method, a server and a system for calculating bandwidth of UDP-based streaming media network transmission. The method includes: dividing video frame data to be sent into a plurality of sub-video frame packets, sending a sub-video frame packet with a preset serial number to a client, and receiving a response message sent by the client, wherein the response message includes a first serial number and a second serial number; sending a sub-video frame packet corresponding to the first serial number to the client, and determining whether the client has received all sub-video frame packets of the video frame data; if so, accurately calculating the actual bandwidth of the current network based on the sending start time of the first sub-video frame packet of the video frame data, the sending end time of the last sub-video frame packet of the video frame data and the size of the video frame data, which provides a basis for the self-adaption of the encoding rate.

Claim (Index 4):
The method for calculating bandwidth of UDP-based streaming media network transmission of  claim 2 , wherein sending the sub-video frame packet corresponding to the first serial number associated with the retransmission count to the client if the retransmission count is greater than a preset retransmission threshold, comprises:\n determining whether the number of sub-video frame packets which have been sent to the client but for which response messages comprising second serial numbers have not been received reaches a preset number threshold; if the number of sub-video frame packets which have been sent to the client but for which response messages comprising second serial numbers have not been received reaches the preset number threshold, selecting, from a sending buffer, a sub-video frame packet whose retransmission count is greater than the preset retransmission threshold according to a preset strategy, and sending the sub-video frame packet to the client; if the number of sub-video frame packets which have been sent to the client but for which response messages comprising second serial numbers have not been received does not reach the preset number threshold, sending a sub-video frame packet, selected from the sending buffer, whose retransmission count is greater than the preset retransmission threshold, and sending new sub-video frame packets and accumulating the count of sub-video frame packets which have been sent to the client but for which response messages comprising second serial numbers have not been received based on the number of the new sub-video frame packets.
