Winter 2006 Joint Techs WorkshopFebruary 7, 2006
Chris CostaCENIC
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 15808 and
15454 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)• 15454 provisioning/troubleshooting
– Cisco Wavelength Director (CWD)• 15808 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
