Abstract: 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.

Abstract: 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.

Abstract: A network management system, and a method of, centrally provisioning a full transport LSP mesh and a full targeted LDP signaling session mesh in support of VPN services provisioning are provided. A network management system repository tracks Provider Edge nodes (PE) having label switch router functionality, transport LSP meshes and targeted LDP session meshes. The method includes selecting PE nodes for inclusion in a node group, identifying PE node pairs, and issuing commands to paired PE nodes to commission managed transport LSPs and targeted LDP signaling sessions.

Abstract: A method of automatic discovery of existing Virtual Local Area Network (VLAN) configuration in a bridged network is provided. The method includes steps of: reconciling a data transport infrastructure in a data transport network; reconciling data transport node configurations; gathering nodal VLAN configurations from all data transport nodes; correlating the data transport infrastructure information, node configuration information and nodal VLAN configurations; and extracting network-wide provisioned VLAN configuration subject to discrepancies. A VLAN auto-discovery application tool having human-machine interface is also provided. The VLAN auto-discovery application tool is operable to initiate the VLAN auto-discovery process and to display the discovered VLAN configuration. The VLAN auto-discovery human-machine interface also is adapted to display a VLAN-specific provisioning status.

Abstract: The present invention comprises a method and apparatus for automatic discovery of network devices with data forwarding capabilities. 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 (identified by its IP number and SNMP description field) is added to a list of discovered network devices. The list is displayed to the network manager, who has the option of selecting none, one, or more than one of the network devices on the network device list for management by the network manager's network management system.
