Patent number: 9450779Abstract: A method for discovering a link between an entry-exit device of a computer network and a customer edge device is disclosed. The customer edge device includes an address and the entry/exit point device includes a routing table. Interfaces with the routing table and addresses of the computer network related to the entry/exit point device are obtained. Either a routing protocol or the routing table is used to obtain routing information. The routing information is compared to a selected address to find a match. The routing information the matches the selected address represents the address of the customer edge device.Type: GrantFiled: May 10, 2010Date of Patent: September 20, 2016Assignee: Hewlett Packard Enterprise Development LPInventors: Sumanth Narasappa, Venkatesh Mahalingam, Kotilingareddy Bhavanam

Patent number: 9438511Abstract: Provided is a method of identifying a Label-switched Path (LSP) associated with a Multi Protocol Label Switching (MPLS) service in a network. An MPLS service is identified in a network and logical neighbors of the MPLS service are determined. For each logical neighbor of the MPLS service, an LSP label is identified. Based on the LSP label, a unique out segment of the LSP associated with the Multi Protocol Label Switching (MPLS) service is identified.Type: GrantFiled: February 7, 2013Date of Patent: September 6, 2016Assignee: Hewlett Packard Enterprise Development LPInventors: Ullas Vasthare Veerappagowda, Akash Deep, Kotilingareddy Bhavanam, Muthukumar Suriyanarayanan, Kashinath Nallapeta Satyanarayana Setty, Chetna Bhagat

Patent number: 9143408Abstract: 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.Type: GrantFiled: July 30, 2012Date of Patent: September 22, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Kotilingareddy Bhavanam, Swamy Jagannadha Mandavilli, Venkatesh Mahalingam, Muthukumar Suriyanarayanan, Anuradha Venkataraman

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
