Method and apparatus for providing automated diagnostics of networks using multiple virtual circuits
Patent number: 7817570Abstract: A method and system for providing automated diagnostics of networks using multiple virtual circuits are disclosed. For example, the method receives a ticket indicating a problem. The method then determines if the problem is associated with a configuration mismatch and determines if the problem is associated with at least one physical channel supporting a plurality of virtual circuits. The method then verifies status of each of the plurality of virtual circuits if the problem is not associated with the configuration mismatch or the at least one physical channel. The method then reports a result of verifying the status of each of the plurality of virtual circuits.Type: GrantFiled: December 31, 2006Date of Patent: October 19, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Thomas Anderson, Paritosh Bajpay, Roberta Bienfait, Mojgan Dardashti, Mark Hunt, Jackson Liu, Zhiqiang Qian, Michael John Zinnikas -
Patent number: 7818283Abstract: A business process automation system architecture is used to isolate problems in a virtual private network access network. Codified rules and a rules based program are used to determine all equipment from a customer premises equipment to a VPN core access point equipment on a VPN access path and that is associated with a failure. The codified rules also govern the gathering of information on the equipment including determining whether the equipment supports automated diagnostics and the communication protocols used. Extended PING testing is done on the equipment and a status of the extended PING test, link status, line protocol status, and existing loop status is determined. Further testing is automatically run based on the codified rules and the status. The failure is then isolated to the CPE, a local exchange carrier, or a network provider.Type: GrantFiled: December 22, 2005Date of Patent: October 19, 2010Assignee: AT&T Corp.Inventors: Paritosh Bajpay, Roberta A.

Patent number: 7688951Abstract: Problems are proactively analyzed and responded to as they are detected in a virtual private network (VPN) access path rather than waiting for a user to manually report the problem. When a problem is automatically detected, such as a failure causing degraded performance, an alarm may be generated. The alarm proactively triggers rules-based analysis procedures and isolation testing to diagnose problem in a VPN access path. Based on the testing and analysis, a comprehensive trouble ticket may be generated that is customized with specific alarm information allowing for increased efficiency in problem isolation and saving significant time and resources in resolving the problem.Type: GrantFiled: December 22, 2005Date of Patent: March 30, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Paritosh Bajpay, Roberta A.

Publication number: 20090157903Abstract: Systems and techniques for managing and acting on trouble reports. A system comprising a plurality of subsystems maintains a central exchange for mediating problem referrals and resolutions between subsystems. A subsystem receives a trouble report and creates a trouble ticket in its native format. To refer the trouble ticket or a problem, the referral information, is translated to a generic format of the exchange. Appropriate problems are referred to subsystems, translating problem information into the native format of a receiving subsystem. Information generated by a receiving subsystem in its native format, including cause and root cause information for the problem, is translated to the generic format of the central exchange, and used to update the trouble ticket. After the central exchange has finished with the trouble ticket, the ticket is translated to the native format of its originating subsystem and further steps are taken by the originating subsystem as appropriate.Type: ApplicationFiled: December 18, 2007Publication date: June 18, 2009Inventors: Stanford Lewis, Mojgan Dardashti, Sridar Seetharaman
