Abstract: A system, method, apparatus and mechanisms for detecting traps triggered by Label Switch Path (LSP) interface events, determining the corresponding event characteristics, associating the detected traps with a bitmap marker indicative of their respective event characteristics, and bundling together bitmaps having common markers to provide thereby respective bundles of common logger events adapted for bulk transmission to a management system.

Abstract: A capability is provided for switching between primary and standby multicast trees on a network egress node of a multicast network. The network egress node includes a first MPLS LABEL Record including a first tree identifier of the first multicast tree, a second MPLS LABEL Record including a second tree identifier of the second multicast tree, and a MULTICAST Record including a plurality of primary tree identifiers and a plurality of standby tree identifiers. The MPLS LABEL Records include parameters, respectively, where the values of the parameters are indicative of respective packet processing rules to be applied for determining whether to accept or discard packets. When the parameter of an MPLS LABEL Record is set to a first value, a determination as to whether to accept or discard a packet received via the associated multicast tree is performed by comparing the tree identifier of the MPLS LABEL Record only to primary tree identifiers of the MULTICAST Record.

Abstract: An embodiment of the invention provides a method and apparatus for restoring a connection in a network. The connection is typically a sub network connection (SNC). In an embodiment, a failed line in a link connecting a first node and a second node is detected, where the failed line is associated with a sub network connection (SNC). The sub network connection (SNC) is then mapped to an alternate line in the link. The first node will change cross connections in a switch fabric in the first node, while the second node will change cross connections in a switch fabric in the second node, so that both nodes can transmit data on the selected alternate line, in order to restore the SNC.

Abstract: A switch of a network. The switch includes a topology database having configuration information. The switch includes a mechanism for sending the configuration information from the topology database to the network and for receiving configuration information from the network and storing it in the topology database. A telecommunications system. A method for operating a telecommunications network.

Abstract: Lines within an aggregated link extending between network elements in a communications system are monitored for faults. Once a fault is detected on a particular line carrying a control channel, an alternative line is selected and control channel is transmitted on the alternative line. Once a control channel is received at a remote end on a new line, the control channel is reassigned to that line. In an alternative embodiment, the control channel is split into separate channels carrying routing and signaling information, respectively. The separate routing and signaling channels are carried by separate lines, but can be reassigned to other lines in response to a fault. Further, the routing information can be carried by multiple lines in an alternating pattern such as a round robin fashion.
