Filed:

Jul 15, 2004

Appl. No.:

10/892072

Inventors:

James E. Sylvester - McLean VA, US
Gaston S. Ormazabal - New York NY, US

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.

International Classification:

H04L 12/24

US Classification:

370468

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.
