The Future Internet
Requirements
Be worthy of our society’s trust Even for managing and operating critical infrastructures
Provide a bridge between physical and virtual worlds Via instrumented and managed sensorized physical environment
Support pervasive computing From wireless devices to supercomputers From wireless channels to all optical light-paths
Enable further innovations in S&E research Seamless access to networked instruments, supercomputers, storage, etc.
Create a social world in which we would want to live

What is Different This Time?
Clean-slate approach To overcome Internet ossification Research not constrained by the features of the current
Internet
A comprehensive coordinated effort Ability to try different approaches (We do not have a
preconceived idea of what they are)
Ability to experiment at scale With real users and applications
Broadnets 2006 510/4/2006
Present: Opaque OEO Optical Networks
Issues:
Doesn’t scale in power or footprint
Expensive OEO interfaces
Static, opex intensive

Dynamic Optical Circuit Switched (DOCS) Networks
Optical circuit switch reduces power consumption—switch wavelengths rather than switching bits.
Smaller, simpler than optical packet switching.

Dynamic Optical Circuit Switched (DOCS) Network Example
Broadnets 2006 810/4/2006
What is needed for a DOCS network?
Optical switches
DWDM mux/demux (Integrated with switch?)
Control plane
Synchronization between control plane and optics

Silicon Evanescent Photonics Integrated Circuit Technology
An approach to integrate passive optical components with active photonic components (lasers, amplifiers, modulators) and electronics.
Mode remains in Silicon
Amplification and modulation in III-V

Issues
Control plane must be simple to allow low latency and high switching granularity Complex control plane would most likely result in large latency
Integration must be simple, low loss, inexpensive Standardized production
Manufacturing must be capable of high volume, minimal handling Drive cost down
Optical Performance Monitoring Electrically switched networks have spoiled us – we have access to all kinds
of performance data Can a set of performance data be defined that can be monitored optically?
