Abstract: In one implementation, an input queue switch provides latency fairness across multiple input ports and multiple output ports. In one embodiment, each input port maintains a virtual output queue for each associate output port. The virtual output queues across multiple inputs are aggregated for each specific output port. The sum of the lengths of the virtual output queues is compared to a threshold, and based on the comparison, feedback may be generated to control the operation of the input port for subsequent packets. The feedback may instruct the input port to stop buffering or drop packets destined for the output port with the sum of the lengths of the virtual output queues associated to the specific output port that exceeds the threshold. In another embodiment, each packet has an arrival timestamp, and a virtual output queue having the oldest timestamp is selected first to dequeue.

Abstract: In a method of measuring packet loss, a flow of packets is identified at first and second locations in a network. The packets in the flow are counted at each of the first and second locations to provide first and second packet counts, respectively. When a trigger packet in the flow is identified at each of the first and second locations, the first and second packet counts are latched to provide latched first and second packet counts corresponding to same packets in the flow. The latched first and second packet counts are compared to measure packet loss between the first and second locations.
