Abstract
The present invention relates to a data transfer method and a system in a computer network to which are connected a number of computers, more specifically to a data transfer method of stream data continuous in time series and a system for it. The present invention makes a request for change of rate from the client 470 in correspondence to the state of vacancy of said receiving buffer 412, and changes the send rate on the server 400 based on that request for change of rate. This prevents any overflow of stream data from the receiving buffer 412. Furthermore, based on the re-transfer request issued from the client 470 in correspondence to the loss of stream data received by said packet receiving means 410, the storing means on the server 400 sends out data corresponding to the lost data concerned. This makes it possible to compensate for the loss in case of occurrence of any data loss.
