US Patent:

7336617, Feb 26, 2008

Filed:

Aug 1, 2003

Appl. No.:

10/632613

Inventors:

Stephen S. Liu - Acton MA, US

Assignee:

Verizon Laboratories Inc. - Waltham MA

International Classification:

H04J 1/16
H04J 3/16

US Classification:

370252, 370465

Abstract:

Method and apparatus for tracking, recording and distributing link state characteristics over communications networks. The invention allows network operators to efficiently define, track, store and disseminate link state characteristics using a bit-field-encoded resource record that is capable of representing many more link state characteristics than the bit-mask-encoded records used in existing systems. As a result, the present invention, when used in conjunction with standard routing and network maintenance algorithms, provides a much more efficient method than existing systems provide, for performing sophisticated networking tasks, such as handling complicated information transmission requests, setting up and tearing down network paths, and making dynamic routing decisions.

Appl. No.:

11/616084

Inventors:

Stephen Shyan-Shiang Liu - Acton MA, US

Assignee:

Verizon Patent and Licensing Inc. - Basking Ridge NJ

International Classification:

G06F 15/173

US Classification:

709223

Abstract:

A device receives a traffic fencing (TF) function for a network, and provides a TF attribute, based on the received TF function, over a link of the network to enable activation of a TF rule of a link state routing (LSR) algorithm used by the network to implement the TF function for the network.

International Classification:

H04L 12/56
H04B 10/20

US Classification:

3703952, 37039551, 370907, 398 58

Abstract:

The present disclosure relates to systems and methods for providing bandwidth-on-demand telecommunications services over next-generation optical transport networks (NG-OTN). One embodiment of a system providing bandwidth-on-demand services includes a next-generation optical transport network (NG-OTN) having an intelligent control plane (ICP) and new-generation synchronous optical network (NG-SONET) capabilities. A next-generation operation support subsystem (NG-OSS) is communicatively coupled to the NG-OTN. The NG-OTN and the NG-OSS are configured to provide the bandwidth-on-demand services.

International Classification:

H04J 3/16

US Classification:

370468, 370255, 370477

Abstract:

Policy-based, on-demand provisioning of optical transport bandwidth is disclosed. In one of many possible embodiments, a system is provided for policy-based, on-demand provisioning of optical transport bandwidth. The system includes a layer-specific operation support subsystem (OSS) configured to manage network elements that form a sub-network over an optical transport network. The optical transport network provides bandwidth-on-demand provisioning capabilities. The layer-specific OSS includes one or more predefined bandwidth provisioning policies. The layer-specific OSS is configured to selectively request on-demand provisioning of bandwidth on the sub-network based on the predefined bandwidth provisioning policies.

International Classification:

G01R 31/08
H04L 12/56

US Classification:

370216, 370252, 370401, 714 2

Abstract:

Systems and methods are provided to implement a full-time protection mechanism and a new class of service offerings based on mechanisms to achieve an ‘always protected’ type of transport service for a networking environment where there may be multiple failures or synchronized attacks. This suite of services may utilize intelligent control plane technology in the optical transport network to support an ‘always on’ protection capability.
