method and apparatus for implementing a service servicequalitätstests

摘要

An apparatus and method for determining the QoS of a communication system. In one embodiment a service verification equipment device (SVE) is placed into the communications link between the wide area network and the transmitting customer premise and an SVE is placed into the communications link between the wide area network and the receiving customer premise. The transmitting SVE inserts a test cell into the customer's data stream over communications link which informs the receiving SVE that a test is commencing. After a predetermined number of customer data cells are sent, the transmitting SVE inserts a termination cell into the communications link at the end of the test. The receiving SVE then compiles data related to the QoS of the communications link and that data is analyzed to determine the QoS.
