METHOD AND APPARATUS FOR MONITORING LATENCY, JITTER, PACKET THROUGHPUT AND PACKET LOSS RATIO BETWEEN TWO POINTS ON A NETWORK

摘要

A system (200) for testing a segment (212) of a data-packet-network (201) has a first probe (203) connected substantially at one end of the segment; a second probe (206) connected substantially at the opposite end of the segment from the location of the first probe; and a process application (304, 306) distributed to each probe. The first and second probes collect data from data packets as they pass and time stamp this data to form first and second records (302, 303) of the individual packets, wherein the first record (302) is located in the first probe and the second record (303) is located in the second probe, whereupon the second-formed records of each packet are compared with the first records of each packet for record matching, time-stamp comparison, and test result processing.
