International Classification:

H04M 1/24
H04M 3/08
H04M 3/22

US Classification:

379 903, 379 1505, 379 2203, 379 33

Abstract:

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.

US Classification:

705 26, 705 27, 705 80

Abstract:

A method for identifying high-risk orders associated with a customer that includes the steps of: receiving an order that includes a customer number, an order type and a plurality of entries; identifying a customer contract based on the order type and the customer number, the customer contract having a plurality of terms that correspond to the entries; comparing the entries to corresponding terms using rules; and identifying a high-risk order containing at least one error from the comparison. The method can also include assigning a result code or a result text to the order, which corresponds to the errors that are identified, and changing the rule set by adding or removing rules.

International Classification:

H04J 1/16

US Classification:

370216

Abstract:

Certain exemplary embodiments can provide a method that can comprise automatically rendering information indicative of a cause of a failure in a Virtual Private Network (VPN) that comprises one or more routers that utilize Virtual Routing and Forwarding (VRF) tables to route traffic via the VPN. The cause of the failure can be automatically determined.

International Classification:

G06F 17/30

US Classification:

707 10, 707204, 707E17005

Abstract:

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.

International Classification:

G06F 11/00

US Classification:

370250

Abstract:

Embodiments of the present invention are directed to diagnosing problems in a dual stack network supporting Internet Protocol Version Six (IPV6). Inventoried information can be retrieved from an inventory system in response to a problem associated the dual stack network. It can be determined whether a mismatch exists between live customer address information associated with a customer edge router and the inventoried information. A notification can be generated in response to determining whether a mismatch exists. The notification includes information representing a cause of the problem and resolution of the problem.
