A method, a device, and a non-transitory storage medium are described in which congestion control service is provided. The congestion control service may include determining whether congestion exists relative to packets and a queue of a network device. The congestion control service may include estimating a communication metric value when congestion exists. A differentiated service field of an Internet Protocol header of each packet is used to carry a portion of the communication metric value. The congestion control service transmits the packets, which include the communication metric value, to an end device. The end device may use the communication metric value to adjust a transmission rate of subsequently transmitted packets.

Communication of congestion information to end devices

A device can receive, from a user device, a transmission control protocol (TCP) synchronize (SYN) packet associated with a request to establish a TCP connection with a server device. The device can prevent a first TCP connection from being established between the device and the user device based on the TCP SYN packet. The device can cause a second TCP connection to be established between the device and the server device based on the TCP SYN packet and after preventing the first TCP connection from being established. The device can cause a third TCP connection to be established between the device and the user device after causing the second TCP connection to be established. The device can transfer network traffic between the user device and the server device based on the second TCP connection and the third TCP connection.
