Abstract: Disclosed is a method of determining, by a network manager, a failure in a ring communications network, including determining a plurality of ring segments within different services of a plurality of services using the ring communications network, determining that there are two or more link failures in the ring communications network, determining the ring segments where the two or more link failures are located, and indicating an interruption of one of the services when the two or more failed links are on different ring segments.

Abstract: Disclosed is a method of identifying service topologies in a network, including determining a group of network devices having a same traffic identifier and indicating each network device of the group as not processed, selecting a first network device that is indicated as not processed in the group, indicating the selected first network device as partially processed, and associating the first network device with a service container identifier, identifying, for each port of the selected first network device, at least another network device in the group indicated as not processed connected to the first network device or a termination point, wherein the identified another network device is identified as partially processed and associated with the service container identifier, repeating step (c) for each identified another network device until only termination points are reached, wherein the identified another network device becomes the first network device in step (c), and when any network devices in the group of

Abstract: According to at least one embodiment of the invention, a protocol for managing redundant signaling links to form a reliable signaling connection is provided. The protocol has an initialization phase, in which the availability of signaling links is determined and an available signaling link is selected and activated, followed by an operational phase in which the activated link is used for sending signaling messages for a higher-level protocol. During the operational phase both links are monitored for availability using a query and reply technique. Should either link fail, a status message is sent to the remaining available link along with an activity switchover being performed, as required, depending on whether the failed link was the active link.

Abstract: Various exemplary embodiments relate to a method and related network node including one or more of the following: displaying, by the network management system, a first representation of a synchronization topology, wherein the synchronization topology includes a set of network elements and a set of peers; receiving a selection of at least one selected network element of the set of network elements; identifying at least one identified peer of the set of peers associated with the at least one selected network element; adding the at least one identified peer of the set of peers to a first synchronization group; and displaying a second representation of the synchronization topology, wherein the second representation includes a representation of the first synchronization group.
