Incorporating Optics into Internet Routers |
Objective
We anticipate that optical technology will be used more and more in Internet
routers - for switch fabrics, serial links, chip-to-chip communications, backplanes
etc. The goal of our work is to explore the problems faced when building a
very high capacity Internet router, and to identify the best use of optical
technology to solve these problems.
Summary
The Optical Router (OR) project is a proposed collaborative research work
in the Electrical Engineering Department
at Stanford University. OR brings together
researchers with interests that range from photonic devices to network switch
design. The initial team working on this project includes Profs. Mark Horowitz, Nick McKeown,
David Miller, and Olav Solgaard,
and their students.
The goal of this project is to motivate interesting research problems, and
in particular those resulting from the combination of several fields involved
in the design of such a router. Interesting fields of research include switch
architecture, linecard design, packet look-up, clock recovery, optical fabric
speed, tunable filters, tunable switches, switch control, link electronics
and packaging.
A more detailed introduction is available. It frames
the project, and describes more thoroughly the router architecture that will
be used. If you are interested in joining this project, please feel free to
contact one of the four professors listed above.
