Patent number: 8737235Abstract: A real-time network-analysis system comprises a network appliance and a plurality of management devices. The network appliance continuously monitors an object network and synthesizes a current network image comprising contemporaneous indicators of connectivity, occupancy, and performance of the object network. A management-client device may gain access to the network image for timely control and for use in producing long-term network-evolution plans. To enable the creation of a real-time network image, optimized topology synthesis algorithms are devised to minimize the computational effort. The real-time network-analysis system is adapted for use with an object network employing a variety of routing protocols, such as link-state protocols, and network-management protocols, such as the Simple-Network-Management protocol.Type: GrantFiled: December 11, 2009Date of Patent: May 27, 2014Assignee: Cavesson Software LLCInventors: Biswajit Nandy, Nabil Seddigh, Rupinder Singh Makkar, Peter Steven Pieda

Patent number: 8125927Abstract: Methods and apparatus for topology discovery of a network having heterogeneous network devices are disclosed. A network appliance communicates with the network devices to acquire device descriptors and characterize the network devices accordingly. Topology discovery is based on device characteristics, media-access data, and encoded connectivity patterns, where each connectivity pattern is defined by devices of specific device types and respective media-access data. A topology deduction module of the network appliance synthesizes a network image starting with unconnected devices and progressively incorporating detected connectivity patterns.Type: GrantFiled: June 18, 2009Date of Patent: February 28, 2012Assignee: Solana Networks Inc.Inventors: Biswajit Nandy, Nabil Seddigh, Sabeel Ansari, Kevin Wong, Rupinder Singh Makkar

Patent number: 7557689Abstract: An alert system for a communications network has a plurality of client devices and a plurality of alert servers each adapted to provide alerts to a respective subset of the client devices to provide scalability. Users at the client devices subscribe to receive alerts by selecting a scope of distribution of alerts. The selection involves selecting a type of alert to receive, a level of severity of alerts to receive, and a geographic scope. In response to receiving a request to issue an alert, an alert server notifies the other alert servers of the alert. Each alert server determines which client devices of the respective subset of client devices are to receive the alert. Each alert server then sends an alert message to its client devices that are to receive the alert.Type: GrantFiled: November 20, 2006Date of Patent: July 7, 2009Assignee: Solana Networks Inc.Inventors: Nabil Seddigh, Biswajit Nandy, Rupinder Singh Makkar, Donald William Arthur Bennett
