摘要： The invention provides a system and method of a selecting an egress connection from egress connections at a node for a call being established in a network along a path being associated with the node. Each connection has sufficient bandwidth to carry the call and terminates at a same destination point in said path. The system and method comprise utilizing at least a bandwidth load balance value for each connection in a set of the connections to select the egress connection from the set. An administrative factor score may be used to further define members of the set.

摘要： A method and system for improving call routing in a PNNI network using crankback messaging. A destination logical group node (LGN) blocked crankback procedure is used by entry border nodes, in the event of a failed connection attempt, to instruct preceding routing capable nodes to route the connection over another link. If the entry border node is in the lowest level peer group a Succeeding End Blocked (SEB) crankback message is sent to the preceding routing-capable node. If the entry border node is not in the lowest level peer group, a destination LGN blocked crankback message is sent to the preceding routing-capable node wherein the message has special information to signal the routing node that the link into the destination LGN is blocked.

摘要： Communication network connection failure protection methods and systems are disclosed. Control information is communicated in a communication network, and causes network elements of the communication network to establish connection monitoring for respective segments of the network connection. Connection monitoring information which is communicated on the segments allows failures such as loss of continuity to be detected and reported. Responsive to an indication of a failure on a segment, the segment on which the failure occurred is identified, and the network connection can be rerouted around that segment.

摘要： There is provided a method of forwarding a traffic flow in a communications network having at least one network node for which network traffic is selectively prevented from transiting the network node. The method includes the step of selecting a specified category of network traffic that is to be prevented from transiting the network node. The method also includes the step of determining a path within the network for forwarding the traffic flow, whereby the network node is excluded for transit in establishing the path where the traffic flow is identified with the specified category of network traffic.

摘要： A system and method are provided for securely establishing Layer-3 SVCs or SPVCs across an ATM network. An originating multiservice switch that generates the connection setup message for the Layer-3 connection includes security information within the setup message, such as a Closed User Group Interlock Code. When the destination multiservice switch receives the setup message, it extracts the embedded security information and compares it with stored security information corresponding to the connection. The correspondence may be determined from the destination user. If the embedded security information matches the stored security information, the destination multiservice switch allows the connection to be established.

摘要： Apparatus and method are provided for dynamically establishing lawful interception taps within connection-oriented communication networks. Taps are established automatically upon establishment of a main connection by embedding collection identifier information within connection setup messages as a new form of information element. The collection identifier information includes information enabling a tap function within an interception node to establish a connection, such as an SPVC or an SVC, to a monitoring station. The collection identifier information may include any of a forward direction ATM address, a backward direction ATM address for use in bi-directional communications, a forward direction end point and a backward direction end point for use in establishing SPVC tap connections, and a connection identifier for use in establishing SVC tap connections. Tap connections can be established either during or after establishment of the main connection.
