Patent ID: 7260627

Claim:
A method of measuring system latency and latency jitter regarding packets of information from sources to destinations, comprising: 1) as the packets of information pass through a plurality of locations formed by components of a network, said locations between sources and destinations of said packets, generating time-stamps at said locations distinct from said packets of information, each time-stamp identifying the packet of information, including time-stamp information based on a real-time clock set to a universal standard; and 2) analyzing at each of the said plurality of locations the time-stamps generated at the plurality of locations in order to determine component latency and latency jitter as said packets traverse from sources to destinations; and 3) applying said analysis of the time-stamps for a plurality of sources and a plurality of destinations on a real-time basis so as to determine a real-time multiple end-to-end latency and latency jitter representing a real-time mesh view of latency and latency jitter regarding the network.
