Abstract
Network communication is carried out by sending packets from a source network interface toward a destination network interface, receiving one of the packets in an intermediate switch of the network, determining that the intermediate switch is experiencing network congestion, generating in the intermediate switch a congestion notification packet for the received packet, and transmitting the congestion notification packet from the intermediate switch to the source network interface via the network. The received packet is forwarded from the intermediate switch toward the destination network interface. The source network interface may modify a rate of packet transmission responsively to the congestion notification packet.
