A method (200, 400), comprising: identifying (202, 402) a flow of packets at each of a first location and a second location in a network, the packets in the flow having at least a common source address and destination address; counting (204, 404) the packets, in the flow, at each of the first location and the second location to provide a first packet count and a second packet count, respectively, the first packet count being counted using a first device and the second packet count being counted using a second device; identifying (206, 406) a trigger packet, in the flow, at the first location using the first device and at the second location using the second device, the trigger packet being identified by comparing first information, included in the trigger packet, to second information defined by a filter, the first information, included in the trigger packet, including at least one of an identifier of the trigger packet, a sequence number of the trigger packet, or a checksum of the trigger packet, the second information, defined by the filter, including two or more of a packet identifier value, a sequence number value, or a checksum value, and the first device and the second device being configured to use the filter; and latching (208, 408) the first packet count and the second packet count upon identifying the trigger packet at each of the first location and the second location, respectively, to obtain a latched first packet count and a latched second packet count corresponding to same packets in the flow, packet loss, between the first location and the second location, being measured using the latched first packet count and the latched second packet count; wherein the trigger packet has at least a common source address and destination address with the other packets in the flow. identifying (202, 402) a flow of packets at each of a first location and a second location in a network, the packets in the flow having at least a common source address and destination address; counting (204, 404) the packets, in the flow, at each of the first location and the second location to provide a first packet count and a second packet count, respectively, the first packet count being counted using a first device and the second packet count being counted using a second device; the first packet count being counted using a first device and the second packet count being counted using a second device; identifying (206, 406) a trigger packet, in the flow, at the first location using the first device and at the second location using the second device, the trigger packet being identified by comparing first information, included in the trigger packet, to second information defined by a filter, the first information, included in the trigger packet, including at least one of an identifier of the trigger packet, a sequence number of the trigger packet, or a checksum of the trigger packet, the second information, defined by the filter, including two or more of a packet identifier value, a sequence number value, or a checksum value, and the first device and the second device being configured to use the filter; and the trigger packet being identified by comparing first information, included in the trigger packet, to second information defined by a filter, the first information, included in the trigger packet, including at least one of an identifier of the trigger packet, a sequence number of the trigger packet, or a checksum of the trigger packet, the second information, defined by the filter, including two or more of a packet identifier value, a sequence number value, or a checksum value, and the first device and the second device being configured to use the filter; and latching (208, 408) the first packet count and the second packet count upon identifying the trigger packet at each of the first location and the second location, respectively, to obtain a latched first packet count and a latched second packet count corresponding to same packets in the flow, packet loss, between the first location and the second location, being measured using the latched first packet count and the latched second packet count; wherein the trigger packet has at least a common source address and destination address with the other packets in the flow. packet loss, between the first location and the second location, being measured using the latched first packet count and the latched second packet count; wherein the trigger packet has at least a common source address and destination address with the other packets in the flow.
