Abstract: A network device implementing the subject system for end to end flow control may include at least one processor circuit that may be configured to detect that congestion is being experienced by at least one queue of a port and identify another network device that is transmitting downstream traffic being queued at the at least one queue of the port that is at least partially causing the congestion. The at least one processor circuit may be further configured to generate an end to end flow control message that comprises an identifier of the port, the end to end flow control message indicating that the downstream traffic should be flow controlled at the another network device. The at least one processor circuit may be further configured to transmit, out-of-band and through at least one intermediary network device, the end to end flow control message to the another network device.
