Abstract: A method for managing identifiers can include receiving, in an identifier management system, a request for an identifier in a computing system. The method can also include verifying availability of the identifier. The method can further include returning an affirmative response to a requesting party.

Abstract: An inter-provider virtual provider network path is identified by identifying a provider network provider edge router having a provider edge interface serving, obtaining routing information from the provider edge router, identifying, from the routing information, a remote customer edge interface of a customer edge router connected to the provider edge router by an intermediate service provider, and identifying the path and associated links between the identified provider edge interface and the identified remote customer edge interface.

Abstract: Systems, methods, and machine-readable and executable instructions are provided for customer edge device problem identification. Customer edge device problem identification can include obtaining a status of a connection between a provider edge (PE) device and a customer edge (CE) device. Customer edge device problem identification can also include determining whether the status of the connection is non-normal. Customer edge device problem identification can include sending an internet control message protocol (ICMP) echo request to the CE device in response to the status of the connection being non-normal. Customer edge device problem identification can include receiving an ICMP echo response from the CE device. Customer edge device problem identification can also include identifying a simple network management protocol (SNMP) problem that is associated with the CE device based upon the receipt of the ICMP echo response.

Abstract: A programmed hardware network configuration file repository indexer is configured with a network-configuration-specific index-operation rule set. In another example, a network-configuration-specific index-operation rule set can be used in generating an index to a network configuration file repository. In the latter example, the index and the index-operation rule set is used in searching the network configuration file repository.

Abstract: Embodiments of the present invention provide a method of providing network information, comprising determining one or more pseudowires between nodes in a network; grouping the pseudowires, according to information associated with each pseudowire and one or more predetermined criteria, into one or more groups each representing a virtual private network (VPN); providing a graphical user interface (GUI) displaying information associated with at least one pseudowire participating in the virtual private network.

Abstract: Presented is a method and system for determining network topology of a Virtual Private Network (VPN) in a Wide Area Network (WAN). The method includes obtaining a list of CE (customer edge) routers in a network, obtaining a list of prefixes advertised by each CE router, iterating, for each prefix, the list of prefixes advertised by all CE routers, verifying, in case a potential hub CE router already exists, whether the second CE router and the potential hub CE router are same, marking, in case a potential hub CE router does not exist, the second CE router as the potential hub CE router, and marking, if there exists a potential hub CE router that advertises every other prefix in the network, the potential hub CE router as hub site and other CE routers as spoke sites.

Abstract: Presented is a method and system of determining network topology of a virtual private network in Multi Protocol Label Switching (MPLS) based Virtual Private Networks (MPLS/VPNs). The method includes obtaining VPN routing and forwarding (VRF) details of at least one virtual private network, determining any variations in network configuration and determining, from said network configuration variations, network topology of the at least one virtual private network.

Abstract: Presented is a method and system for deriving the path of a traffic engineering tunnel in a network using Multi Protocol Label Switching, MPLS, traffic engineering and a Management Information Base, MIB, describing managed objects of the network. The method comprises: obtaining node connectivity information from the MIB; obtaining network connectivity information from a network node manager; and deriving tunnel path information based on the node connectivity information and the network connectivity information.

Abstract: Network topology data or data indicating a topology of a network, is analyzed and refined by merging portions of the data and removing false data from the network topology data. For example, network topology data is processed by evaluating interface data, deleting erroneous data from the network topology data based on the evaluating, and merging data in the network topology data based on the evaluating.
