Patent number: 8929225Abstract: 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.Type: GrantFiled: December 7, 2012Date of Patent: January 6, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Swamy Jagannadha Mandavilli, Anuradha Venkataraman, Kotilingareddy Bhavanam, Muthukumar Suriyanarayanan, Venkatesh Mahalingam

Publication number: 20130238629Abstract: 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.Type: ApplicationFiled: March 8, 2012Publication date: September 12, 2013Inventors: Ram Kumar Kosuri, Swamy Jagannadha Mandavilli, Murali Mohan Dingari

Patent number: 8144624Abstract: 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.Type: GrantFiled: October 22, 2009Date of Patent: March 27, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Srikanth Natarajan, Swamy Jagannadha Mandavilli, Lawrence M. Besaw, Anuradha Venkataraman

Patent number: 8000265Abstract: 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.Type: GrantFiled: June 12, 2009Date of Patent: August 16, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Kotilingareddy Bhavanam, Muthukumar Suriyanarayanan, Swamy Jagannadha Mandavilli

Patent number: 7424021Abstract: 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.Type: GrantFiled: January 31, 2003Date of Patent: September 9, 2008Assignee: Hewlett-Packard Development Company, L.P.Inventors: Gabriel Brandon Wechter, Swamy Jagannadha Mandavilli, Zhiqiang Wang
