Claim Text:
1. A method, comprising: transmitting a latency packet via a network test device to at least one remote node in a communication network; generating, via tile network test device a first timestamp associated with transmission of the latency packet; receiving the latency packet at the network test device, the latency packet being reflected from the at least one remote node; generating a second timestamp associated with receiving the latency packet at the network test device; receiving a third timestamp and a fourth time stamp at the network test device, the third timestamp being associated with receipt of the latency packet by the at least one remote node and the fourth time stamp being associated with transmission of the latency packet to the network test device by the at least remote one node, wherein the third and fourth timestamps are transmitted by the at least one remote node in one or more packets different from the latency packet, wherein the third and fourth timestamps are recorded and then transmitted by the at least one remote node in one or more data packets different from the latency packet; and determining a network latency of the communication network via the network test device based on a difference between the second timestamp and the first timestamp and a difference between tile fourth timestamp and the third timestamp.
