Appl. No.:

10/817192

Inventors:

Swamy Mandavilli - Fort Collins CO, US
Philip A. Flocken - Fort Collins CO, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06T 15/00

US Classification:

345773, 345419, 345473, 345751

Abstract:

A method and system for maintaining persistence of graphical markups created within a collaboration environment that associates graphical markups with the camera position is presented. The collaboration tool provides utilities to allow saving the graphical markups to the user's local disk, saving the graphical markups into a PDM system (either locally or remotely), and saving the entire collaboration session including graphical markups, notes, action items, etc. , When saved to persistent storage, all the camera positions and all graphical markups associated with them are stored in the markup file. The saved markups/session can later be reloaded from the user's local disk or a PDM system as appropriate. When a session is loaded into the collaboration session, all of the camera positions and associated graphical markups from the saved session are then accessible, allowing simple viewing of the results of the session, continuation-of-work, or asynchronous collaboration. After a markup file is loaded the contents are accessible to all the members of the current collaboration session.

International Classification:

H04L 12/28

US Classification:

370392, 370252, 370254, 370401

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.

H04J 3/14

US Classification:

370245, 370241, 370243, 370244

Abstract:

In an embodiment, a network service provider (NSP) operates a provider network to provide VPN services to its customers. A VPN links various customer sites allowing customers to send data between these sites over the NSP network. Each site network includes a customer edge router (CE) while the provider network includes a plurality of provider edge routers (PEs) to communicate with the CEs. The PEs include virtual routing address (VRFs), and the PEs and CEs include interfaces (IFs). A database stores information related to the relationships between the network components (e. g. , VPNs, PEs, CEs, VRFs, IFs, etc. ), and a management software package (MSP) has access to the database. When a fault occurs, the MSP, based on collected information and information in the database, determines the impacted network components. Other features include classifying the seriousness of the network's faults and representing different faults by a color scheme.

International Classification:

H04L 12/28
G06F 15/177

US Classification:

370254, 709220

Abstract:

A topology or connectivity of a computer network is discovered by identifying interface addresses in an address table of a node in the network, comparing prefixes of the interface addresses with prefixes in an address prefix table of the node, and associating subnets in the network with interfaces corresponding to the interface addresses, based on the comparing.

US Classification:

709224, 709223

Abstract:

In an exemplary embodiment, a method for managing a network includes monitoring a network using an interior gateway protocol to detect change in the network, and determining effects of the detected network change on Multi Protocol Label Switching paths in the network. For example, the MPLS paths can be the same as IGP best paths. An exemplary embodiment includes managing a Multi Protocol Label Switching network by discovering edge routers in the Multi Protocol Label Switching network, determining possible combinations of Multi Protocol Label Switching path end points based on services provided within the network, selecting discovered edge routers for observation, based on the determined possible combinations, monitoring the selected edge routers, and determining status of Multi Protocol Label Switching paths in the network based on the monitoring.

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.
