Multisource and multipath supported data transmission management method

The invention provides a multisource and multipath supported data transmission management method. The method mainly comprises the steps of establishing MS-MPTCP connection between a source device and terminals and adding sub-source devices to the MS-MPTCP connection, wherein the sub-source devices carry out data communication with a source or the terminals through utilization of the MS-MPTCP connection based on a plurality of paths; and receiving data from the source or the terminals by sub-sources, allocating transmission paths to data packets by the sub-source devices according to sizes of data packets and transmission delay of each path, and allocating transmission bandwidths to the terminals according to receiving windows of the terminals and the bandwidth of each path. According to the method, demands of multisource and multipath cooperation for path congestion sensing and path allocation scheduling can be satisfied; the paths can be flexibly allocated to the terminals; the congested windows of the termi
