Real time mesh measurement system stream latency and jitter measurements
First Claim
1. A method of measuring system latency and latency jitter regarding packets of information from sources to destinations, comprising the steps of:
- 1) time-stamping packets of information that pass through a plurality of locations between sources and destinations of packets, said time-stamping with a real-time clock set to a universal standard; and
2) analyzing the time-stamped packets to determine latency and latency jitter as said packets traverse from sources to destinations.

Abstract
A method is described for measuring system latency and latency jitter on a near real-time basis regarding packets of information moving from sources to destination. The method for measuring system latency and latency jitter includes time-stamping packets of information as they pass through a plurality of locations between the source and destination of these packets, with the time-stamping being performed by real-time clocks set to a universal standard. The time-stamped packets are analyzed to determine latency and latency jitter. The measurements of system latency and latency jitter can be performed based upon packet types so as to obtain accurate information concerning different types of business bandwidths associated with an observed network.
