摘要： A method for optimizing an established call routed across a network from an originating exchange to a destination exchange over a first connection path. The first connection path features a path metric of interest, such as administrative weight. A second connection path is identified which features an improved path metric, the path is made operative and the call is directed over the second connection path. Thereafter, the first connection path may be dismantled. The second connection path is preferably identified by signalling a call set-up message over the network, wherein the message incorporates a reporting field and each transiting exchange propagating the message updates the reporting field until it specifies the path metric of the replacement connection path traversed by the call set-up message. A connect message incorporating the reporting field back is signalled back to the originating exchange from the destination exchange. If the reporting field specifies an improved path metric the replacement connection path is then identified; otherwise the process may be repeated until such time as the second path is found. Alternatively, if the call set-up message includes a desired connection path metric value and the network is configured to clear back the call set-up message to the originating exchange in the event it is unable to identify any connection path to the destination exchange satisfying the desired path metric, the replacement connection path may be automatically accepted.

摘要： There is provided a method and apparatus for the ordered release of connections from a network entity in a signalling communications network upon the detection of the failure of a signalling link or a port corresponding to such connections. A priority indicator is associated with each of the connections. Each priority indicator is selected from a priority hierarchy having several priority levels which varies from highest priority to lowest priority. Upon detection of the failure of a signalling link or port, every connection associated with the failed signalling link or port is released. The release of the connections takes place at the network entity in a sequence which corresponds to the priority hierarchy. A method and device are also provided for the ordered release of connections carried on a logical truck having a variable capacity, for example an IMA trunk, upon the detection of a reduction in capacity. The IMA trunk may be provided on several physical links. A priority indicator and traffic rate are associated with each of the connections carried on the IMA trunk. Upon detection of the reduction in bandwidth, a group of connections having an aggregate traffic rate corresponding to the reduced capacity of the IMA trunk is selected and the connections of the group are released in a sequence corresponding to the priority hierarchy.

摘要： A method and apparatus for controlling multicast group subscriptions in a multicast distribution circuit is presented. When a router included in the multicast circuit receives notification to terminate support of a particular multicast group (group leave request), data flow with respect to that multicast group is initially maintained on the communication link coupling the router to the hosts. Queries are issued to hosts on the communication link to determine whether continued support of the particular group is desired by any hosts coupled to the communication link. If, while waiting for a positive response to the queries issued, a request to join an additional multicast group is received, bandwidth availability on the communication link is examined to determine if adequate bandwidth is available for supporting the newly requested group addition. If adequate bandwidth is available, the newly requested group is added to those groups supported on the communication link. However, if adequate bandwidth for support of the newly requested group is not available, one or more groups that are pending termination (group specific queries have been issued for these groups) are selected for early termination in order to make enough bandwidth available to support the newly requested group addition. The selection criteria utilized to determine the groups to be terminated may be based on a variety of parameters.

摘要： There is provided a method and apparatus for establishing a connection across a connection oriented network to enable communication between an originating network element and a destination network node. The originating network element is connected to source network node in the connection oriented network by a source communications channel which is addressable in the connection oriented network. The connection oriented network has a signalling infrastructure employing a network signalling protocol for establishing connections within the connection oriented network. A connection establishment request message is generated for requesting the establishment of the connection between the originating network element and the destination network node and includes information identifying the source and destination communications channels. A proxy connection establishment request message is sent from a network controlling element to the connection oriented network over a proxy signalling link provided therebetween. The proxy connection establishment request message is received at the connection oriented network and the channel identifying information is extracted from the proxy connection establishment request message. A network connection establishment request message according to the network signalling protocol is then generated and sent over the signalling infrastructure to establish a path between the source network node and the destination network node. The path is connected to the communications channel identified in the proxy connection establishment request message, thereby establishing the connection between the originating network element and the destination network node.

摘要： A method of converting a permanent connection, such as a PVC, into a signalled permanent connection, such as an S-PVC, in a connection-orientated network, such as an ATM network, without service disruptions. The method includes the steps of: (a) establishing signalling links between each network node along the path of the permanent connection; (b) providing information to identify the cross-connections along the path; (c) incorporating the cross-connect identification information in a call set-up message; (d) signalling the call set-up message along the path from a source network node to a destination network node; and (e) associating the cross-connection of each node along the path with the appropriate signalling links in order to form the signalled permanent connection. The cross-connect identification information may be a unique call identifier for the permanent connection, in circumstances where the call identifier is associated with the permanent connection cross-connections prior to Step (d). Alternatively, the cross-connect identification information may be a permanent connection path definition specifying each cross-connection is the path. A similar method for converting a signalled permanent connection into a permanent connection is also disclosed.

摘要： A method of re-establishing a communications connection in a network element, a network element and a switched connection communications network are provided. The communications connection is re-established after a failure occurs affecting the communications connection. The network element is a network element in a switched connection communications network over which the communications connection is provisioned in a source-to-destination bearer path. The bearer path includes a cross-connection in the first-mentioned network element. The cross-connection is associated with the communications connection prior to the failure at a time when the communications connection is provisioned. The method includes the steps of: (a) delaying release of the cross-connection following the failure and (b) during the delayed release, determining whether the cross-connection remains operable notwithstanding the failure and, if so, re-associating the operable cross-connection with the communications connection to thereby re-establish same over at least that portion of the bearer path which includes the cross-connection.
