An apparatus and a method for managing network flow congestion are provided. The method for managing network flow congestion includes: receiving a plurality of packets; identifying whether each packet belongs to a predetermined protocol; distinguishing a plurality of connections of the packets belonged to the predetermined protocol; monitoring a buffer usage of each different connections; and performing a congestion check procedure on the currently monitored connection. In the congestion check procedure, when the buffer usage of the currently monitored connection exceeds a threshold, a congestion processing procedure is triggered.

A network congestion notification method and network node are provided in a network system. The network node receives a remote direct memory access (RDMA) packet, where the RDMA packet carries a source queue pair number corresponding to a transmit end and a destination queue pair number corresponding to a receive end. The network node generates a congestion notification packet when detecting network congestion, where a destination queue pair number of the congestion notification packet is the source queue pair number. Then the network node sends the congestion notification packet to the transmit end so that the transmit end may decrease a sending rate of a data flow to which the first data packet belongs.

Examples described herein relate to a network agent, when operational, to: receive a packet, determine transmit rate-related information for a sender network device based at least on operational and telemetry information accumulated in the received packet, and transmit the transmit rate-related information to the sender network device. In some examples, the network agent includes a network device coupled to a server, a server, or a network device. In some examples, the operational and telemetry information comprises: telemetry information generated by at least one network device in a path from the sender network device to the network agent.

A device, communication system, and method are provided. In one example, a system for routing traffic is described that includes a plurality of ports to facilitate communication over a network. The system also includes a controller to selectively activate or deactivate ports of the system based on queue depths and additional information to improve power efficiency of the system.
