The invention discloses a network congestion control method combining an active mode and a passive mode. The method comprises the following steps that a sending end divides a data stream into a plurality of data packet chains; the sending end directly injects the speculated data packet chains into the network in sequence according to the data packet granularity; a router in the network counts accumulated queuing time and updates the accumulated queuing time; the router checks whether the accumulated queuing time of the speculation data packet exceeds a preset threshold value or not, and if not, the speculation data packet is normally transmitted; after the speculation data packet arrives at the receiving end, the speculation data packet is absorbed from the priority buffer queue to be processed; after receiving the authorization message returned by the receiving end, the sending end activates the subsequent data packet chain, and when the receiving end receives the last data packet ofone stream, the sending e
