1. A method of network congestion control, comprising:
sending, by a transmit end device, forward probe packets to a destination device at a preset initialized rate, wherein some or all of the forward probe packets arrive at the destination device after being forwarded by an intermediate device in a network by using a reserved bandwidth of an egress port of the intermediate device;
receiving return probe packets returned by the destination device, wherein the return probe packets correspond to the forward probe packets received by the destination device; and
determining a data packet sending rate based on the received return probe packets, and sending a data packet at the data packet sending rate, wherein the data packet arrives at the destination device after being forwarded by the intermediate device by using a link bandwidth other than the reserved bandwidth of the egress port of the intermediate device.
