Appl. No.:

11/618906

Inventors:

Thomas Anderson - Imperial MO, US
Paritosh Bajpay - Edison NJ, US
Roberta Bienfait - Norcross GA, US
Mojgan Dardashti - Holmdel NJ, US

Assignee:

AT&T Intellectual Property II, L.P. - Reno NV

International Classification:

H04J 1/16

US Classification:

370252, 370241, 370242, 725108, 709224, 714100

Abstract:

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.

International Classification:

H04J 3/14
H04L 12/26
G06F 15/173

US Classification:

370218, 370242, 370250, 709224

Abstract:

According to one method for identifying and resolving a silent failure in a telecommunications network, performance data associated with data traffic passing through a network element in the telecommunications network is collected. A determination is made whether the performance data has fallen below a threshold to identify the silent failure at the network element. The silent failure fails to trigger an alarm included on the network element. Responsive to determining that the performance data is below the threshold and thereby identifying the silent failure at the network element, troubleshooting rules may be retrieved. The silent failure is resolved based on the performance data and the troubleshooting rules.

International Classification:

H04L 12/24

US Classification:

370237, 370235

Abstract:

A method and apparatus for addressing a congestion condition in a communication network are disclosed. For example, the method receives an alert for at least one of: a trunk or a Permanent Virtual Circuit (PVC), where the trunk or the PVC is associated with a route. The method determines whether the alert is associated with a congestion condition by determining whether a trunk utilization has exceeded a first predetermined threshold for the trunk or for the at least one trunk supporting the PVC. The method then rebuilds the route if the first predetermined threshold is exceeded for the trunk or for the at least one trunk supporting said PVC.

International Classification:

H04J 1/16

US Classification:

370242, 370252, 370216, 725105, 709232

Abstract:

A method and system for providing automated diagnostics of networks using multiple physical channels are disclosed. For example, the method receives a ticket indicating a problem and attempts to identify at least one physical channel of the network that is a potential cause of the problem. The method runs at least one diagnostic test on the identified physical channel and reports a result of said diagnostic test.

Appl. No.:

11/618909

Inventors:

Paritosh Bajpay - Edison NJ, US
Monowar Hossain - Middletown NJ, US
Mark Hunt - Plano TX, US

International Classification:

G01R 31/08

US Classification:

370248

Abstract:

A method and apparatus for providing trouble isolation for a Permanent Virtual Circuit (PVC) on packet networks are disclosed. For example, the method receives an alert or a ticket for a Permanent Virtual Circuit (PVC) down or a PVC degraded and starts a correlation window for said PVC and port alert or ticket. The method then gathers a plurality of port and PVC alerts for a duration of said correlation window and determines whether or not a port down or a port degraded alert is received along with a PVC down or a PVC degraded alert in said correlation window for one or more ports associated with said PVC.

Assignee:

AT&T INTELLECTUAL PROPERTY I, L.P. - Reno NV

International Classification:

H04L 29/04

US Classification:

370468

Abstract:

A system that incorporates teachings of the present disclosure may include, for example, a system having a controller to monitor in a communication system bandwidth utilization by CPE, detect bandwidth utilization by the CPE that exceeds a bandwidth utilization limit, reconfigure a portion of the communication system to accommodate the increase in bandwidth utilization by the CPE, and generate a mitigation plan directed to a user of the CPE to address the increased bandwidth utilization by the CPE. Other embodiments are disclosed.
