Claim:
A method for communication, comprising: sending communication packets over a network from a first network interface; receiving in the first network interface a notification, which originates from a second network interface and indicates a network congestion encountered by one or more of the packets; identifying a network address of the second network interface by extracting a source address from the notification; and responsively to the notification, regulating a transmission rate of subsequent packets that are addressed to the network address, irrespective of a transport service instance on which the subsequent packets are sent from the first network interface, wherein the notification indicates that the network congestion is encountered by the packets sent on a first transport service instance in the first network interface, and wherein regulating the transmission rate comprises controlling the transmission rate of one or more subsequent packets that are addressed to the network address and are sent on a second transport service instance in the first network interface, different from the first transport service instance.
