Abstract
An optical network and method for managing a service across an optical network over a dedicated circuit between first and second service termination points include generating a service performance report message (PRM) at each service termination point. Each service PRM has service-specific information related to a performance of the service as determined by the service termination point generating that service PRM. Each service PRM identifies the service to which the service-specific information in that service PRM pertains. Each service termination point transmits the service PRM generated by that service termination point across the optical network over the dedicated circuit to the other service termination point through a service management channel of an optical transport facility. Either of the first and second service termination points is accessed to evaluate an end-to-end performance of the service based on a comparison of the service PRM generated by the first service termination point with the service PRM generated by the second service termination point.
