Security is weak
Availability/Reliability is an issue
Instrumentation is weak
Predictability is weak
Manageability is an issue
Our Critical Infrastructures Cannot Rely on it!
Mobility is not well supported
Sensing is not well supported
Scalability is an issue
Persistent problems not solvable by incremental
improvements to the current Internet
New Paradigms may prove more powerful, providing
the basis for a superior Future Internet

Reasonable Representation of the Internet’s Complexity
A Nationwide Optical Network ~ 200 Universities
Clusters for Processing/Storage
Wireless Access Networks
• Mobility, Location Awareness
– Sensor Networks
– Connected to a large number of User Communities
• Partnerships to Extend GENI within the US
– Add Technologies and Users
• Federation to Extend GENI on a Global Scale

- share resources to support many simultaneous experiments
GENI Design Principles
• Physical network ‘substrate’
– building block components
– elements / nodes / links / subnets
• Software control & management framework
– knits building blocks together
– allows many parallel experiments (slices)
– creates arbitrary logical topologies (virtualization)
• Programmable for ‘Clean Slate’ research
• Instrumented for accurate analysis
• Flexible and Phased Design
– Support Technology Introduction during GENI Lifetime

Still in the Formative Stages
‘GENI Science Plan’ under revision
GENI Facility ‘Conceptual Design’ almost complete
Next stage looking to broaden participation
– Look for ideas from interested parties
– Stronger coupling with ‘Physical Layer’ Communities
• Optical Networking
• Wireless Networking
– Stronger coupling with Internet Applications
– Social and Behavioral Issues
– Economic issues

GENI and Optical Networking
• Clearly differentiate three areas:
– The GENI Facility
– Optical Networking Research for the Future Internet
– Optical Technologies that will impact the Future Internet
• Developed externally, included into GENI when mature
The GENI Facility will allow research into
Optical Networking and allow the inclusion of
new Optical Technologies as they mature
during the GENI lifecycle
Optical Networking Research
• Tight Integration of Physical Layer with Higher Layers
• Provide a Dynamic Optical Networking Plane
– Dynamic Optical Switching/Routing
• Fiber Switching
• Wavelength Switching (WDM)
• Sub-Wavelength Switching - O/E/O, Optical Burst/Packet Switching?
• ‘All’ Optical Networking
– Combines Transmission Issues with Optical Switching/Routing
• Data Rates/Modulation Formats effect Network Design
– Feed Information to Higher Layers (conditions)
• New Optical Networking Paradigms?
– Non-SONET/SDH? Non-Telecom? e.g. Multicast, rate adaptive…
• Control Plane and Management
• Quantum Key Distribution - at Network scale
Physical Technologies
• Computing
• Storage
ECONOMICALLY
(no cost scaling!)
• Communications
2 to 3 Orders of Magnitude
Scaling Required
Processing, Capacity, Routing/Switching
From tera to peta (exa?) (flops, byte, bps)
Access Technologies, Mobility
Sensor / Display (I/O) Technologies
Optical Device Technologies
• Photonic Integration - KEY to Economic Scaling
– Very dense and inexpensive O/E/O
– High Functionality PICs: Optical Switching, Routing, …
– Silicon photonics
• Integration with CMOS, Manufacturing Infrastructure Sharing
• Microstructured Optical Fibers
– Customizable optical properties (transmission/all optical networks)
• Will a new technology cause a fundamental paradigm shift?
GOAL: Flexible GENI design; supports
introduction of New Technologies as they mature
