Patent number: 9729426Abstract: A method and system that takes advantage of processes that are efficient for determining the topology of small to medium size networks to determine individual network topologies for such networks, and then merges these individual topologies into a consolidated topology for the entire network. Each of the processes that determines the topology of the smaller networks provides the determined network topology, as well as a list of factors that may be relevant in the determination of how the given topology might be attached to any other given topology, such as the identification of a node that is not included in the given topology, or other indications of external connections. The merging process is configured to substantially restrict its analysis to these factors, thereby limiting the extent, and therefore the time consumed, by this stitching and merging process.Type: GrantFiled: January 9, 2014Date of Patent: August 8, 2017Assignee: RIVERBED TECHNOLOGY, INC.Inventors: Raghavendra B.

Patent number: 9087299Abstract: The connectivity information provided by a variety of inference engines is integrated to provide a set of inferred links within a network. A consolidation is performed among inference engines that operate at a base level of connectivity detail to create a model of the network at this base level. The connectivity information provided by inference engines at each subsequent higher level of connectivity abstraction is then overlaid on the base level connectivity. By separately consolidating the connectivity information at each level of abstraction, the rules for dealing with conflicts can be simplified and/or better focused to resolve the conflict. By assuming that the more detailed lower level information is likely to be more accurate, rules can be developed to modify the connectivity models produced by the higher level techniques to conform to the lower level connectivity details while still maintaining the integrity of the higher level connectivity models.Type: GrantFiled: April 23, 2014Date of Patent: July 21, 2015Assignee: RIVERBED TECHNOLOGY, INC.Inventors: Raghavendra B.

Patent number: 8948049Abstract: Networks and devices may communicate with each other using virtual connections. In one embodiment, a computer-implemented model is generated and includes a representation of the path of a virtual connection. The path of a virtual connection, such as an IP tunnel, is traced between its source and destination. The physical connection corresponding to such IP tunnels are found by tracing through the device configuration and routing tables at routers in the network. The path between the source and destination devices is traced until the path is terminated at the destination device, or at an interface to an external network. If the path ends at an external network, the path is traced from the destination device toward the source device until a corresponding interface to the external network is reached.Type: GrantFiled: April 23, 2012Date of Patent: February 3, 2015Assignee: Riverbed Technology, Inc.Inventors: James Mark Shaw, Raghavendra B.

Patent number: 8165038Abstract: The physical connection corresponding to IP tunnels in a network are found by tracing through the device configuration and routing tables at the routers in the network to determine the outbound interface associated with each tunnel endpoint, and then inferring a likely return interface associated with the opposite tunnel endpoint. Having determined the physical devices at the source and destination of each tunnel, the physical path between these source and destination devices is traced from the source toward the destination until the path is terminated at the destination device, or at an interface to an external network. If the path ends at an external network, the path is traced from the destination device toward the source device until a corresponding interface to the external network is reached.Type: GrantFiled: August 14, 2008Date of Patent: April 24, 2012Assignee: OPNET Technologies, Inc.Inventors: James Mark Shaw, Raghavendra B.
