The examples of the present invention provides a multi-source transmission system of an IM file, which includes a sender IM terminal and a receiver IM terminal which are connected with each other through a network and exchange data; the receiver IM terminal is configured to search for replicas of a file according to file information sent by the sender IM terminal, and when at least one replica is searched out, receive the file from at least two file sources by using a multi-source mode, wherein the at least two file sources comprise the sender IM terminal and a file source of the at least one replica. In the examples of the present invention, conventional P2SP system is used to search for the replicas, and the file with a replica is received by using the multi-source transmission mode, thereby improving the speed of file transmission and bandwidth utilization ratio. |
