GENI Substrate Working Group

This is the GENI Substrate Working Group wiki. Please contribute! Joe Evans and Kristin Rauschenbach are the working group chairs. John Jacob is the working group system engineer. To find out what the Substrate working group does, browse these pages and read the working group charter. If you have comments or suggestions on the charter, please send them to the substrate-wg mailing list. If you have comments or suggestions about these pages, feel free to log in and improve their content. To view past archives of the mailing list, see the mailman archive or the nabble archive.

Substrate-WG Announcements

When you subscribe to a GENI working group mailing list (such as substrate-wg), you also get a wiki account that uses the same username and password. You should get an email letting you know when the wiki account is created, which allows you to login and start contributing. The "login" link is at the top of this page. The login works for all GENI working group pages.

Substrate-WG Contents

We are working on a complete list of GENI resources. Please contribute.

Some GENI topics overlap the intersts of more than one working group. Here's the substrate group's table of what information we'd like to exchange with other working groups to help clarify substrate design issues. We'd like to see other working group members review and add to the Common Interests table.

Substrate-WG Background

The substrate working group was formed in early October 2007. Prior to that time, the GENI planning group generated a series of documents that provide some background on the GENI substrate. While these GENI Design Documents (GDD) may not reflect the most up-to-date "GENI thinking", they do convey important GENI concepts and principles from a number of different perspectives. GDD's may be downloaded at References to substrate can be found in most all of the GDDs, however, the following documents are particularly relevant to substrate activities:

  • Tom Anderson, Larry Peterson, Scott Shenker, Jonathan Turner, "Overcoming the Internet Impasse Through Virtualization," GENI Design Document 05-01, April 2005.
  • Daniel J. Blumenthal, John E. Bowers, Craig Partridge (Eds), "Report of NSF Workshop on Mapping a Future for Optical Networking and Communications," GENI Design Document 05-03, July 2005.
  • Larry Peterson (Ed), "GENI Design Principles," GENI Design Document 06-08, GENI Planning Group, March 2006 (updated August 2006).
  • Joe Evans, Dipankar Raychaudhuri, Sanjoy Paul, "Overview of Wireless, Mobile and Sensor Networks in GENI," GENI Design Document 06-14, Wireless Working Group, September 2006.
  • Jennifer Rexford (Ed), "GENI Backbone Run-Time Software for Experimenters," GENI Design Document 06-36, Backbone Working Group, November 2006.

Background information is also available in the presentations made at the Substrate Working Group meeting held at the first Geni Engineering Conference, the presentation and audio from the session may be downloaded at
