  • Method and apparatus for clearing a large number of connections in an ATM network
    Patent number: 7415025
    Abstract: A method for clearing a plural number of connections from each of two connected nodes by clearing the first connection from the first node, generating a single first message from the first node to the second node identifying the connections, clearing the connections from the second node in response to the receipt of the first message, and generating a second message from the second node to the first node identifying the connections cleared by the second node in response to the second node receiving the first message. Furthermore, a node having circuits for generating and interpreting each of the two messages, and maintaining a database of connection status. Further, each of the two message types that signal a clearing of a plurality of inter-nodal connections.

  • Technique for managing heavy signaling traffic that is directed to a particular signaling control unit
    Patent number: 7298753
    Abstract: A method is described that involves sending a positive imposter response as a consequence of a status request message having been received. The status request message refers to a network connection. The status request message was sent to the networking system to ask the networking system to inquire into the status of the network connection.

  • Method to exchange resource capability information across network peers
    Patent number: 7269169
    Abstract: A method and apparatus to exchange resource capability information between two network peers. The signaling protocol is used to encapsulate resource capability information as a datagram within a user-definable data protocol data unit. In an ATM network using the SSCOP signaling protocol, the UD PDU may be used as a transport mechanism for resource capability information that cannot be exchanged via the ILMI protocol. VPI/VCI range information for a partitioned link may be encapsulated as a datagram within the UD PDU and exchange between nodes via the SSCOP. SSCOP UD PDU datagrams may be used in accordance with the present invention to exchange resource capability information between nodes. Alternatively, SSCOP UD PDU datagrams may be used to validate information exchanged via the ILMI protocol.
