• The implementation is lambdas (unprotected).
• Installed shelf capacity and common equipment
  permits expansion of up to 16 lambdas through
  deployment of additional OCLD, and OCI modules.
• A fully expanded OM5200 system is capable of
  supporting 64 lambdas (unprotected) over the same
  4-fiber span.

OMNInet Key Themes and Issues

• A Key Goal Is Enhancing Service Layer
  Abstractions and Enabling Direct Manipulation of
  Core Optical Resources
• Major Improvements Over Centralized Control of
  Core Resources Via High Distributed Control
• Decentralization Applications Can Directly
  Control Lightpaths
• Advanced Dynamic Lightpath Provisioning Based on
  Controllable, Deterministic Optical Networks
• Increased Integration Between Edge and Core
  Infrastructure
• Agile Solid State Components (e.g, CMOS-Based,
  PIC-Based)
• Availability of Cost-Effective Fiber and DWDM
  Equipment Provides for Highly Disruptive
  Price/Capability Ratios
• Ref-- iGRID2005

OMNInet Key Research Issues

• Research Basic Should Be Oriented Toward
  Difficult Fundamental Problems vs Specific
  Implementation Issues
• Research Must Be Oriented to Long Term Objectives
  
• Large Scale Research Testbeds Are Required To
  Investigate Grand Challenges of Advanced
  Networking
• Research Environments Must Allow for Multiple,
  Different Experimental Approaches
• Prototypes Are Key Resources
• Research Projects Supporting Interdisciplinary
  Methods for Enabling Applications with Advanced
  Research Infrastructures Are Important
• Communications Infrastructure Research Funding is
  Required
