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 interworking device is provided that affords an interface between a point-to-point (P2P) environment and a local access network (LAN) environment. The interworking device comprises a P2P frame transceiver adapted to communicate with a P2P host utilizing P2P frames formatted in accordance with a P2P protocol. A LAN frame transceiver is adapted to communicate, over a LAN environment, with a LAN host utilizing LAN frames formatted in accordance with a LAN protocol. The P2P and LAN frames include client traffic having client level network layer (NL) information associated with a common predefined client level network layer protocol. A data forwarding module utilizes the NL information to map the client traffic from at least one of i) the P2P frames into the LAN environment and ii) the LAN frames into the P2P environment.

Abstract: In accordance with one aspect of the present invention, a network topology management system is provided for managing distribution of network topology information between nodes within a network that performs a distributed source routing protocol. The system includes, nodes distributed throughout a network, that are interconnected by node-to-node links, each of which is described by associated link state information. The system includes a control module that is joined to the nodes and that receives the link state information from each node. The control module records the link state information in master routing tables to form an overall topology map of the network. The control module stores predetermined policy statements that define a manner in which the link state information should be distributed between the nodes. The control module creates abridged routing tables by modifying the link state information based on the predetermined policy statements.

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.
