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.

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： A method and apparatus for establishing a test connection to verify the ability to automatically re-establish control plane connections, if necessary, in a PNNI network. Certain routing features such as restricted transit feature and policy based routing features or the current stat of the network itself can limit access to nodes and links between nodes. If these features are implemented in a network or the network state changes after a control plane connection has been established, then these changed conditions will not affect the current connection but may prevent the re-establishment of the connection if it is unintentionally dropped. According to the invention a test connection is periodically set-up through the network and if the test connection fails an alarm or other notice is given. This allows for preventative action to be taken in order to avoid disruption to the network.

摘要： A system and method are provided for a multi-endpoint SPVC, the multi-endpoint SPVC providing redundancy. A primary SPVC is established through a first source node. An intermate communication channel (ICC) is established between the first source node and a second source node. If the primary SPVC fails, the second source node learns of this via the ICC and establishes an alternate SPVC. If the first source node fails, the second source node learns of this failure without having to be explicitly told. The second source node learns of the failure of the first source node when poll messages are no longer received over the ICC as indicated by expiry of a timer. In such an event, the second source node attempts to establish an alternate SPVC. Finite state machines are provided on each source node to monitor the status of each other. Command messages, in the form of Generic Application Transport information elements, are provided by which the finite state machines can communicate over the ICC.

摘要： The invention enables an LSP or embedded LSPs to be mapped directly to an SPVC and carried over the ATM network. A unidirectional SPVC is established by associating it to a particular ingress LSP at the SPVC source endpoint on a multi-service switch, and to an egress LSP on the SPVC destination endpoint on another multi-service switch. The information necessary to establish the SPVC is appended in the SPVC setup message and includes LSP specific information such as the far end router ID and LSP label information, be it transport label or the full label stack. The information in the modified setup message is then used by the destination endpoint to find and connect the SPVC to the correct LSP. Incoming traffic from the LSP is switched to the SPVC at the source endpoint. The SPVC carries this traffic through the ATM network, and then the traffic is switched to the egress LSP when it emerges from the ATM network at the destination endpoint.

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 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： A method and apparatus are provided for protecting a connection during implementation of an Active Connection Modify request. Before initiating the ACM request, an alternate connection between the source node and the destination node of the connection are established using Domain-Based Rerouting. The alternate connection may be established in conformance either with the traffic parameters of the existing connection or with the new traffic parameters specified in the ACM request. If the connection along the original connection is to be torn as a result of lost ACM signaling messages, the connection is first switched to the alternate connection in a hitless manner. If the alternate connection is established in conformance with the new traffic parameters, and the ACM request can not be implemented along the original connection, due for example to resource shortage along the original connection, then the connection is switched to the alternate connection in a hitless manner. In this way, connections are protected in the event of lost ACM messages resulting from signal congestion, and the ACM may be implemented even in the event of resource shortage along the original connection.
摘要翻译：提供了一种用于在实现活动连接修改请求期间保护连接的方法和装置。在启动ACM请求之前，使用基于域的重新路由建立连接的源节点和目标节点之间的备用连接。备用连接可以与现有连接的流量参数或ACM请求中指定的新流量参数一致地建立。如果原始连接的连接由于ACM信令消息丢失而被破坏，则连接首先以无中断的方式切换到备用连接。如果根据新的流量参数建立替代连接，并且ACM请求不能沿着原始连接实现，例如由于原始连接的资源短缺，则连接被切换到无连接的备用连接方式。以这种方式，在由信号拥塞引起的ACM消息丢失的情况下，连接被保护，并且即使在沿着原始连接的资源短缺的情况下也可以实现ACM。

摘要： A method for policy-based routing of calls between nodes in a network, comprising: entering policy constraint indices for selected addresses in respective entries of an address translation table, the address translation table for accessing by a first node of the network to selectively translate attributes of calls based on respective addresses prior to transmission over the network to a second node, the policy constraint indices pointing to respective policy constraints for routing calls between the first and second nodes; receiving a call at the first node, the call including an address; accessing the address translation table using the address to determine whether the call requires assignment of a policy constraint by presence of an entry for the address in the address translation table and by presence of a policy constraint index in the entry; and, if the call requires assignment of a policy constraint, identifying a policy constraint with the policy constraint index, assigning the policy constraint to the call, and routing the call between the first and second nodes in accordance with the policy constraint.
