Claim:
1. A method for generating a one-way latency profile in a network comprising: transmitting a plurality of pre-synchronization messages between a requester node comprising a first clock and a responder node comprising a second clock; calculating, using a pre-synchronization data set contained in one of said pre-synchronization message, a pre-synchronization offset value between said first clock and said second clock; transmitting a plurality of measuring messages comprising a sending time between said requester node and said responder node; recording, by said responder node, said sending time and a receiving time of each of said measuring messages; transmitting a plurality of post-synchronization messages between said requester node and said responder node; calculating, using a post-synchronization data set contained in one of said post-synchronization message, a post-synchronization offset value between said first clock and said second clock; interpolating said sending and receiving times of said measuring messages with said pre-synchronization offset value and said post-synchronization offset value to create a plurality of latency measurements, and generating said one-way latency profile from said plurality of latency measurements.
