CENIC/NLR Optical Networks Winter 2006 Joint Techs Workshop February 7, 2006 Chris Costa CENIC

Agenda Provide overview of CENIC and NLR’s Optical Networks. Define the tools and processes used to support these networks. Identify some of the challenges in supporting large optical networks.

CENIC Optical Backbone DWDM Long Haul systems Supports up to 80 channels in C-Band Utilizes Cisco and ONS platforms Supports CalREN Multi- tiered routed backbone Provides dedicated lambdas for researchers

National Lambda Rail DWDM Long Haul / Extended Long Haul systems Utilizes Cisco 15808/15454 Platforms Provides dedicated 10GE/OC192 P2P circuits

Network Management Systems Individual NE provisioning tools –Cisco Transport Controller (CTC) provisioning/troubleshooting –Cisco Wavelength Director (CWD) provisioning/troubleshooting Centralized NMS. Overview of all NE’s in the topology, across multiple spans in the network. –CTM - Cisco Transport Manager Inventory Management Fault Management Performance Management Configuration Management

Performance Management Performance Monitoring Reports –Real time and trend analysis reports –Provides Forward Error Correction Statistics

Commissioning Data Reports Provides detailed analysis of optical parameters –Run prior to and after maintenances and service interruptions

Optical Spectrum Analyzer Isolate specific wavelengths across a composite signal Identify bad filters / broken transmitters / bad connections

Challenges NE connectivity during fiber cuts –complex routed solutions Hybrid Management systems –Utilize CTM and CTC/CWD to provision and troubleshoot –Alarm correlation NMS Upgrades to support new hardware Documentation –Keeping provisioning data up to date Deploying test equipment Configuration History –Audit Trail
