Appl. No.:

10/892072

Assignee:

Verizon Services Corp. - Arlington VA

International Classification:

H04J 14/08

US Classification:

398 45, 398 98

Abstract:

A system for performing testing and analysis of a DWDM optical switch in a computer controlled, automated manner for switches from multiple vendors is described. The introduction of automation of the testing configuration and the extensive use of protocol adaptation to provide a consistent user interface for the test apparatus across multiple vendor implementations through the use of programmable adapter modules facilitates systematic and efficient testing. Proper functionality of a given optical switch implementation, quantification of a system's parameters and determination of switching performance measures can be obtained. Capabilities are built into the analysis engine for the determination of Service Level Agreement (SLA) parameters that can be provided for the optical layer or as input to calculations of SLA at higher-level protocols. The automated apparatus provides an efficient tool for evaluating and comparing DWDM optical switching devices, e. g. , devices from different manufactures, which use different switch control protocols.

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.

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.

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.

International Classification:

H04N 7/10
H04N 7/025

US Classification:

725 32, 725 34

Abstract:

A device receives a request for an advertisement from a set-top box (STB) displaying television content in a high definition format, and provides, to the STB, the advertisement in a standard definition format, where the high definition format includes a resolution higher than a resolution of the standard definition format. The device also determines whether the STB converts the advertisement from the standard definition format to the high definition format. When the STB fails to convert the advertisement from the standard definition format to the high definition format, the device generates a first error code and instructs the STB to continue to display the television content, without interruption, in the high definition format.
