Abstract
Methods, systems, and computer-readable media for measuring packet delays are provided. An input port of a network device is tapped to duplicate an input packet stream having a first packet. An output port of the network device is tapped to duplicate an output packet stream including the first packet. The duplicated input packet stream and the duplicated output packet stream is transmitted to a programmable device. The first packet in the first input packet stream is matched to the first packet in the first output packet stream. An arrival time and a departure time for the first packet is measured. The difference between the departure time of the first packet and the arrival time of the first packet is determined and the value is reported to an external collector.
