Abstract: Each node of a telecommunications network determines a connection type attributes available for each signal type supported by the node. Each signal type represents a different connection routing layer within the telecommunications network. Adaptation costs involved in traversing from one connection routing layer to another connection routing layer in the node are calculated. The connection type attributes and adaptation costs are included in a link state advertisement broadcasted by each node in the telecommunications network. A route calculation is performed for a desired signal to determine a route through the telecommunications network for the signal. The route calculation takes into account the various connection type attributes, availability, and adaptation costs in determining the shortest route for the signal through the telecommunications network.

Abstract: An apparatus which enables first and second signaling networks to communicate with one another via one or more proxies. Each respective proxy can edit a received message and translate an included address to an address associated with a receiving signaling network.

Abstract: A method and system are provided for verifying connectivity between monitoring points (MPs) within a network. The method comprises assigning, to each monitoring point, a unique MP ID and a unique sender MP ID and a unique receiver MP ID. Each sender MP ID uniquely identifying a sender MP from which a corresponding MP will receive valid monitoring messages. Each receiver MP ID uniquely identifying a receiver MP to which the corresponding MP transmits a valid monitoring message. The method further includes transmitting the monitoring messages MP ID in a unidirectional monitor cycle through the MPs, where each monitoring message includes a sender MP ID and a receiver MP ID. The method determines connectivity at each MP based on the sender and receiver MP IDs in a monitoring message received at the MP. Optionally, the method and system may report, from a monitoring point, a loss of connectivity when no valid monitoring message is received at the monitoring point for a predetermined number of monitor intervals.
