ABSTRACT:
A method and system for monitoring a first virtual circuit in an asynchronous transmission mode (ATM) network comprises the steps of establishing in the network a second virtual circuit with the same path and QoS parameters as the first virtual circuit, and monitoring the first virtual circuit by determining the QoS parameters of the second virtual circuit. Specifically, a monitoring station determines the QoS parameters of the second virtual circuit by inserting monitoring information in cells transmitted and received on the second virtual circuit. The monitoring station inserts the monitoring information immediately before transmitting each cell and immediately after receiving each cell. Furthermore, the monitoring station compares the QoS parameters of the second virtual circuit with the QoS parameters of the first virtual circuit to determine network alarm information.
