摘要： A method, system and diagnostic tool for diagnosing a problem in CSPF and non-CSPF MPLS networks, including problems with LDP tunnels. This includes one or more of the following: hopping from network element to network element; determining whether an LSP between elements is operational; determining whether the hop was strict or loose; evaluating whether there is an existing path between the elements; finding and remembering an IGP link between the elements; recognizing whether the LSP is an FRR LSP; diagnosing a cause of the LSP between the elements being down; and altering a display of a topology map of the network to indicate the cause of the problem.

摘要： A method and system for managing the distribution of multicast content are provided. The method involves creating a list of multicast group addresses to be made available to user units supported by a group of nodes. The list is distributed to all of the nodes in the group of nodes. Filters are created to limit the multicast content that each user unit can receive. The filters are created by referencing the list of multicast addresses previously created. The filters are distributed to the appropriate nodes and applied on customer ports.

摘要： A method of interacting with a managed data network entity is provided. The method includes a sequence of steps. A change in the operational state of the managed data network entity is detected. A CLI dictionary entry is retrieved form a CLI dictionary associated with the data network entity. Based on the retrieved CLI dictionary entry, CLI commands are extracted therefrom to configure the managed data network entity to reflect the detected change in the operational state. A CLI command sequence is built from the extracted CLI commands. Each CLI command in the command sequence is sent to the managed data network entity for execution. CLI command responses are monitored. Based on a successful execution of CLI commands send, subsequent CLI commands in the CLI command sequence are sent for execution. The solution provides automated configuration management of data network entities from different vendors when SNMP is not a viable option. The automation eliminates manual CLI command entry in providing network management and service provisioning solutions, provides support for multi-vendor equipment by processing multiple CLI command vocabulary and grammar specifications in the CLI command dictionary. The solution reduces data network entity management costs, downtime, and training time for analysts. The advantages are derived from the ability to add CLI commands to the CLI dictionary providing support for new types of data network entities with human readable code greatly improving the development and maintenance of the network management and service provisioning solution.

摘要： An embodiment of the present invention provides a method for network management that allows the configuration of IP links in one step, via a GUI form, even though the management protocols available at the two end links (routers) may differ. According to one embodiment, the method comprises gathering information from the user, validating this information, and then sending this information to the appropriate router(s). According to one embodiment, the method enables a user to specify various configurations when provisioning an IP link, for example, the type of IP link (Point-to-Point, Point-to-IP, or Point-to-Subnet), the numbering type (Numbered or Unnumbered), the application type (MPLS and/or IP Forwarding), and the sub-layer interfaces to be used (Packet Over Sonet, Asynchronous Transfer Mode, GigEthernet, and others). In addition, according to one embodiment, the method allows the IP link to be associated to existing router interface(s), or the interfaces can be created as part of the IP link creation process.

摘要： In one embodiment, the present invention sends SNMP queries to sets and/or ranges of IP numbers to determine whether a network device exists at each IP number and whether the network device has IP forwarding capabilities. The set of IP numbers searched may be specified by specifying ranges or subnets or by providing a list of discrete IP numbers. When a new network device with IP forwarding capabilities is discovered, that network device is added to a list of discovered network devices. The list is displayed to the network manager. In one embodiment, in addition to discovering newly added devices via IP number polling, the invention also discovers newly added devices from SNMP messages (“traps”) broadcast by a newly added device. In one embodiment, each network device discovered as a result of a SNMP trap is added to the newly discovered device list.

摘要： A method and human-machine interface for backbone Virtual Local Area Network (VLAN) provisioning in bridged networking environments are provided. The method includes steps of provisioning backbone VLAN support on every backbone data transport trunk and by extension of every stackable data trunk port in the associated data transport network. The human-machine interface enables an operator to expediently effect VLAN provisioning abstracting the intricacies of the data transport network over which VLAN services are provisioned. Advantages are derived from backbone VLAN provisioning independent of an underlying in-use active spanning-tree topology. In particular backbone VLANs are provisioned over spanning-tree stand-by designated backbone data transport trunk links and therefore preprovisioned in the case of spanning-tree re-configuration. Customer VLANs are mapped onto backbone VLANs ensuring data traffic differentiation, and providing standard VLAN identifier portability. Operator VLAN provisioning tasks are lessened via provisions for the selection of all backbone/stackable data transport trunk links/ports in the data transport network in effecting VLAN identifier associations therebetween.

摘要： The present invention comprises a method and apparatus for automatic discovery of logical links between network devices. In one embodiment, the present invention comprises part of a network management system (“NM”) that manages a discrete set of network devices. The NM sends SNMP queries to individual network devices managed by the NM to obtain interface configuration data for each of the network interfaces of the device. The information requested includes destination information (“next hop” or “neighbor” IP address) for data packets sent from the interface. The NM checks to see whether a logical link corresponding to the received configuration information already exists in a logical link database maintained by the NM. If such a link exists the NM checks to see if the existing information for the link is valid. If the existing link data is valid, no change is made. If the existing information is not valid, or if no corresponding link is found in the link database, the NM creates a new link corresponding to the new configuration information. In one or more embodiments, the NM displays a graphical view of the discovered IP links on a graphical network map.

摘要： Routing path calculation apparatus and methods are disclosed. Calculation of routing paths within different routing areas of a communication system is handled by respective routing path calculation devices. Multiple devices may be requested to perform respective routing path calculations for segments of a routing path between endpoints in different routing areas. Recalculations may be requested from the same or different devices in the event of a change in a routing area that affects a segment of a routing path. A routing path calculation device, whether or not in this type of distributed routing path calculation system, may determine whether a previously configured path exists between an intermediate node of a calculated routing path, and take the previously configured path into account in calculating the routing path if it is determined that a previously configured path exists. The previously configured path may be an Interior Gateway Protocol (IGP) shortcut, for example.
