Abstract: This disclosure provides methods and systems for reducing congestion in RoCEv2 networks. The method is configured to operate large-scale in data centers on traffic flowing from a sender node to a receiver node. The method described has three stages: a fast start stage, a transition stage, and a regulation stage. In the fast start stage, the sender sends data to the receiver at a fast initial rate. This may continue until the receiver observes a congestion event. When this happens, the sender reduces the data transfer rate as the method enters the transition stage. From a reduced rate, the method enters the regulation stage, where the rate is increased using a combination of a feedback control loop and an additive increase multiplicative decrease (AIMD) algorithm.

Abstract: A network device, including ports that receive/send data packets from/to a network, receives data packets of multiple traffic flows, and populates a queue in memory with the data packets. The network device periodically updates a fair rate for the multiple traffic flows to converge a length of the queue to a reference length. Specifically, the network device determines a length of the queue, a change in the length from a previous length, and a deviation of the length from the reference length. The network device detects an increase in the change in length above a threshold that is based on the reference length. If the increase is not above the threshold, the network device derives the fair rate from a previous fair rate using proportional integral control. The network device identifies elephant flows among the multiple traffic flows, and sends the fair rate to a source of each elephant flow.

In some examples, latency is based on a measured roundtrip time and a baseline roundtrip time.
