摘要： A source node receives related frames of data to be transmitted from the source node to a destination node and places the frames in a queue. The queue is associated with a communication path over which the related frames are to be transmitted to the destination node. An interface that couples the source node to the communication path receives an indication directed to the source node of traffic congestion in the communication path. In response, the source node controls the rate at which the related frames of data are transferred from the queue to a transmit buffer accessible to the interface, in order to relieve the traffic congestion in the communication path.

摘要： According to one embodiment of the invention, a method comprises measuring traffic congestion experienced by a message transmitted from a source device, and if the measured traffic congestion exceeds a threshold limit, altering at least one bit within a Layer 2 (L2) header of the message. This bit alteration is subsequently used to determine when to notify a source of the message that the message experienced traffic congestion.

摘要： A node uses a two dimensional array of transmit queues to store frames to be transmitted from the node to another node. The size of the array is governed by the number of directions to which the other node may forward frames once received from the node, and the number of priorities that may be associated with the frames. The transmit queues are distinguished from each other based on direction and priority. A transmitter transmits frames dequeued from the transmit queues to the other node. Control logic that controls the transmit queues receives an indication from the other node whether the other node is experiencing traffic congestion in any of the directions and the priority of frames at or below which the control logic is to control the dequeuing of frames from transmit queues corresponding to the directions in which the other node is experiencing traffic congestion.
