SYSTEM AND METHOD FOR OUT-OF-LINE REAL-TIME IN-SERVICE PERFORMANCE MEASUREMENT

摘要

A system for out-of-line testing of performance of a network, comprising a multiplexer at an input to the network; a demultiplexer at an output from the network; said multiplexer further comprising a traffic generator to insert synthetic traffic, and a first switch to accept an incoming customer traffic stream and join said incoming customer traffic stream with a synthetic traffic stream to form a total traffic stream, said total traffic stream fed to said input to said network; and said demultiplexer comprising a second switch to receive said total traffic stream from said output of said network, and separate said total traffic stream into the synthetic traffic stream and the customer traffic stream, and a traffic analyzer to analyze said separated synthetic traffic stream.

1. A system for out-of-line testing of performance of a network, comprising
a multiplexer at an input to the network; a demultiplexer at an output from the network; said multiplexer further comprising
a traffic generator to insert synthetic traffic, anda first switch to accept an incoming customer traffic stream and join said incoming customer traffic stream with said inserted synthetic traffic stream to form a total traffic stream,said total traffic stream fed to said input to said network; and said demultiplexer comprising
a second switch to receive said total traffic stream from said output of said network, and separate said total traffic stream into the synthetic traffic stream and the customer traffic stream, anda traffic analyzer to analyze said separated synthetic traffic stream.
