iCAIR’s Optical Metro Network Initiative
(OMNI)
• Goal: Create Reference Model: Design and Develop Optimal Optical
Metro Network, Using Leading Edge Architectures and Technologies
• Initiated in November 1999, Announced at CANARIE Workshop Nov.
2000
• Research and Development
• Early Implementations and Trials (“Crash and Burn” Testbeds- eg
OMNInet currently a “concept” - vs Production)
• OMNInet partners, include EVL, ANL MCS, CANARIE
• New Architectures and Protocols
• Very High-Performance, Large-Scale Metro Opt Networks
• Hybrid Systems
• Advanced Photonics, Dynamic Switching, Wavelength Routing
• Next Generation OMN Management Systems Performance &
Measurement Tools

Next Generation Metro Optical Nets
• New Optimal, Open Architectures for Multi-Functional
Optical Metro Networks
• IETF considerations as well as ITU
• IP-Based Control Plane within OptNet
• Allows for More Optimal Architecture:
–
–
–
–
–
High-Performance Core - Less Reliance on SONET
Complexity Pushed to Edge - Smart Ingress Systems
Gateways and Interfaces to Traditional Systems, eg, ATM, SONET
Gateways and Interfaces to Supplemental Tributary Systems
GE, 10GE, Wireless BB, etc
• Designed for Expandability, Scalability, Flexibility,
Customization at Edge, Dynamic Provisioning, Efficient
Management, Cost Effectiveness

Fiber Builds as Construction Projects
Cost-Efficient Approaches
Hardened, All Weather, Physical Infrastructure
Leveraging Rights of Way
Minimize Street Demolition/ Trenching via Use of Existing Structures
= Lowers Costs by 50%
Vaults, Conduits, Tunnels, etc.
Existing City Infrastructure
New Infrastructure Foundations for Fiber
Partnerships with Other Infrastructure Developers, eg. Transportation,
Sewer, Utilities, etc.

Future-Proof Fiber Builds
Accelerate Decline in Cost of Fiber and Access
Ensure Ubiquitous, Inexpensive Fiber - Commodity Fiber
Cost-Effective Deployments, eg, Tunnel Robots
Condominium Fiber
Dark Fiber/Dimly Lit Fiber
DWDM Fiber
SMF-28 vs MM vs Leaf vs MetroCore
Alternative Types of Metro Fiber, eg, Support for ZDF and CWDM
New Types of Fiber, eg, “Plastic Fiber” “Wireless Fiber”

Optical Component Issues
• Core Backbone Architectural Orientation Toward Digital
Communications vs Traditional Connection-Oriented, Circuit
Switching, eg IP-Based Control Planes within OptNet
• Minimalization (Elimination over Time) of Traditional SONET (eg,
Reduction of Complexity Cost, and Inefficiency - 50% Not Utilized)
• Introduction of Emerging Technologies within Optical Core
• New DWDM Techniques, Static Bandwidth Lightpath OCX
• Incremental Wavelength Provisioning, New Types of Framing
• Lightwave Mesh Architecture and Technology
