In one of many possible embodiments, a system includes a first reference node and a second reference node communicatively coupled to the first reference node by at least one network path, the reference nodes being configured to support transmission of a packet flow between one another over the network path. Each of the reference nodes is configured to count data packets received, the data packets being associated with the packet flow, and to latch a count of a number of the data packets received. The system includes a monitoring protocol configured to request the reference nodes to latch the respective counts. The monitoring protocol is further configured to retrieve the respective counts from the reference nodes and use the counts to determine a packet delivery measurement associated with the transmission of the packet flow between the reference nodes. |
