A file transmission method and system. The method includes steps of: establishing at least two connections to a receive end, each connection including at least one send window (S101); dividing a to-be-sent file into at least two data blocks, filling a corresponding data block in a send window of each connection, and sending the data block to the receive end by using the send window (S102); acquiring acknowledgement information returned, after the receive end receives the data block, by the receive end, the acknowledgement information including data block information received this time and data block information that the receive end expects to receive (S103); and clearing, according to the acknowledgement information, a send window corresponding to the data block information that is received this time by using the connection, filling, in the cleared send window, a data block that the receive end expects to receive, and sending the data block to the receive end by using the send window (S104). Utilization of bandwidth is improved and a file transmission time is reduced by means of multi-connection and multi-window concurrency and proper data block distribution. |
