The invention discloses a method, a device and a system for controlling network congestion, and solves the problem that network congestion cannot be prevented according to real-time changes of network bandwidth. The technical scheme of the method, the device and the system for controlling network congestion is as follows: when a first timer meets a preset interval sent by detection, a first detection message is sent to an objective terminal; a first response message corresponding to the first detection message returned by the objective terminal is received; receiving time of the first response message is acquired; when a second timer meets a preset monitoring interval, current time is acquired; a time difference between the current time and the time when the receiving time of the first response message is finally received by the current time is taken as a corresponding response time; and according to the relation of the corresponding response time and a preset response time difference value, the sending rate of data is adjusted. The method, the device and the system for controlling network congestion are applied to the communication field.
