Abstract: Communication system management apparatus, methods, and interfaces are disclosed. A group of objects that are associated with different types of communication system components in a representation of a communication system are configured in a group. A further representation of the objects of the group is provided, and includes an indication of component operational status for one or more communication system components respectively associated with one or more of the objects of the group. The further representation of the objects of the group may also or instead provide access to the objects of the group, so that information associated with the objects may be more easily displayed, for example. The communication system representation and the group representation are provided in a Graphical User Interface (GUI) in some embodiments.

Abstract: A method for monitoring a point-to-multipoint unidirectional multicast connection via exchange of OAM messages is presented. The method includes retrieving the connection record of the multicast connection from a network management system repository and determining common parent path points between the root and a selected path branch endpoint. In turning on content conveyance monitoring for a termination other than the root, the termination specific uncommon portion of the transport path is segmented if necessary, OAM compliant managed path segments are identified, and OAM configuration commands to turn on OAM functionality are issued only to uncommon path segment endpoints.

Abstract: Methods and systems for communication network element configuration and connection rerouting are disclosed. For a communication network connection between network elements, one of which supports a local connection rerouting function to detect a loss of continuity on the connection based on continuity check signals and to reroute the connection responsive to the detection and another of which does not support the local connection rerouting function, the non-supporting network element is configured to send continuity check signals to the supporting network element over the connection, and the local connection rerouting function is enabled at the supporting network element. The supporting network element then monitors the connection to detect loss of continuity and reroutes the connection responsive to the detection.

Abstract: A network management and administration system provisioning data links in an optical networking environment is provided. The network management and administration system makes use of connectivity information in establishing and monitoring data links. The connectivity information includes data link termination specifications. Data link termination specifications include port and channel specifications. Each port may have a channelized or an unchannelized configuration. A virtual channel having a data transport capacity substantially equal to that of a corresponding unchannelized port is defined therefor. The advantages include a standardized, concise and comprehensive provisioning and presentation of data links.
