Abstract
A method for communication includes transmitting a sequence of outgoing data blocks from a network node over a communication link to a peer node, and receiving incoming data blocks from the peer node. A control field is added in a predefined location in each of the outgoing data blocks in the sequence by the network node. In at least a first subset of the outgoing data blocks in the sequence, the control field contains error control information, which is capable of causing the peer node to retransmit one or more of the incoming data blocks to the network node, while in at least a second subset of the outgoing data blocks in the sequence, disjoint from the first subset, the control field contains a flow control instruction, configured to cause the peer node to alter a rate of transmission of the incoming data blocks over the link.
