2OptIPuter 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
