US Patent:

8284685, Oct 9, 2012
Filed:

Nov 12, 2008
Appl. No.:

12/269500
Inventors:

Paritosh Bajpay - Edison NJ, US
Shiu Chong - Fair Haven NJ, US
Olivier Daude - Nice, FR
David Lu - Morganville NJ, US
John Mayr - Raleigh NC, US
Anand Singh - Marlboro NJ, US
Sarma Tanuku - Freehold NJ, US
Assignee:

AT&T Intellectual Property I, L.P. - Atlanta GA
International Classification:

G01R 31/08
US Classification:

370252
Abstract:

A method and apparatus for managing a virtual private network are disclosed. For example, the method collects performance data for at least one parameter from a plurality of customer edge routers and a plurality of provider edge routers associated with the virtual private network. The method correlates the performance data for identifying one or more performance exceptions based on a threshold for each of the at least one parameter, and performs a trending analysis using the one or more performance exceptions to predict a potential problem that will impact the virtual private network.

Filed:

Jan 3, 1991
Appl. No.:

7/637244
Inventors:

James D. Askew - Ellenwood GA
Chin-Wang Chao - Lincroft NJ
David R. Cochran - Easton PA
Peter M. Dollard - Highlands NJ
Hossein Eslambolchi - Freehold NJ

Assignee:

AT&T Bell Laboratories - Murray Hill NJ
International Classification:

H04J 116
US Classification:

370 16
Abstract:

A restoration system is provided for enhancing the reliability of a telecommunications network such that particular traffic which is disrupted by, for example, a faulty link, may be quickly rerouted via an alternate route established "on the fly". In particular, each node and link forming the network is monitored, and in the event that such monitoring detects a faulty link or node then a central controller is notified. The controller is arranged to locate spare capacity and establish an alternate route, in which the continuity of the alternate route is confirmed before the disrupted traffic is transferred thereto.
