PERFORMANCE MEASUREMENT DEVICE FOR A TELECOMMUNICATIONS PATH

摘要

A device (PMD) and a method for measuring the performances characteristics of a communication path of a telecommunication packet switching network (ATM) by transmitting test packets through this path while other life traffic is operating. The test packets are life data communication packets of the life traffic and of which the communication data has been replaced by performance measurement data. No traffic of test packets is thereby added to the existing life traffic and the latter is not disturbed by the measurements.
