OptIPuter Optical Architecture Themes

• The OptIPuter Shapes Itself to Meet the Precise
  Needs of the Application Requirements vs. Todays
  Environments in which the Application must be
  Compromised to Conform to Infrastructure
  Restrictions
• The OptIPuter Enables the Creation of Dynamic
  Virtual Computers Instantiations, Releasing
  Resources after Use
• Resources Include Optical Networking Components
• Dynamic Lightpaths Supported by Next Generation
  Optical Networks
• For the OptIPuter, the Network is No Longer a
  Network, but a Large Scale, Distributed System
  Bus
• An Optical Backplane Based on Dynamically
  Provisioned Datapaths, Including Lightpaths
• Also, the OptIPuter Uniquely Addresses the Needs
  of Extremely Large Scale Sustained Data Flows
  Even Those Exhibiting Dynamic Unpredictable
  Behaviors
• Achieving These Goals Requires New Architecture,
  Methods and New Technologies at All Levels L1
