Abstract

A channel performance monitoring system for an optical network is provided which comprises measuring means for measuring the Signal to Noise Ratio (SNR), bit error rate (BER) and power level of a signal at selected points in the network; and a network management system, including comparing means to compare data from the measuring means with known data relating to the network, and processing means to process data from the comparing means to determine channel performance information. The invention provides intelligence within a network management system (NMS) to enable an optical channel to be set up automatically across an existing all-optical network infrastructure and ensure that it conforms to an agreed performance specification. Where non-compliance is identified corrective action can be applied either automatically and problem reports issued or, alternatively, the circuit is flagged as non routable, again with appropriate reports. Corrective action may be in the form of changes to the circuit configuration of operating conditions (within accepted profiles), by invoking protection switching or by other means.
