description A network device comprises time measurement units configured to measure receipt times and transmit times of packets received/transmitted via network interfaces. One or more memories store configuration information that indicates certain network interface pairs and/or certain packet flows that are enabled for latency measurement. A packet processor includes a latency monitoring trigger unit configured to select, using the configuration information, packets that are forwarded between the certain network interface pairs and/or that belong to the certain packet flows for latency monitoring. One or more latency measurement units determine respective latencies for packets selected by the latency monitoring trigger unit using respective receipt times and respective transmit times for the packets selected by the latency monitoring trigger unit, calculates latency statistics for the certain network interface pairs and/or the certain packet flows using the respective latencies, and stores the latency statistics in the one or more memories.
