A network operating system NOS for an agile optical network with a plurality of mesh interconnected switching nodes, manages the network using an object-oriented network information model. The model is common to all applications requiring the data stored in the network managed information base. The core model can be expanded for serving specific application areas. The NOS is organized in layers, at the optical module level, connection level and network level. A distributed topology server DTS organizes the physical, logical and topological data defining all network entities as managed objects MO and topology objects TO for constructing a complete network view. The network information model associates a network element NE information model, specified by managed objects MO and a topological information model, specified by topology objects TO. The MOs are abstract specific NE data that define network implementation details and do not include any topological data, while the TOs abstract specific topological data for defining a trail established within the network, and do not include any NE data. The models are associated in a minimal number of points to construct the model of a trial in response to a connection request.

An automatically configurable network monitoring system includes a network monitoring communications protocol used for communications between a network monitoring client executing on a routing node (100) being monitored and a network monitoring server executing on a network monitoring processor (106). According to the network monitoring communications protocol, the network monitoring client broadcasts a network monitoring service request message to the network monitoring servers. The service request message identifies a signaling link for which network monitoring service is being requested. The network monitoring servers provisioned to the requested provide network monitoring service respond affirmatively and thereby automatically grant network monitoring service. The network monitoring system may be completely probeless or, alternatively, used in conjunction with probe-based network monitoring devices.
