Most of my work on past projects have been reported in my papers. 
Here are pointers to projects I worked on that, for one reason or another, never got
published.

*[http://blizzard.cs.uwaterloo.ca/keshav/home/Projects/real The REAL network simulator]. I no longer maintain REAL. However, REAL begat ns, which begat ns2, so its spirit lives on.

* At AT&T Bell Laboratores, I worked on a [http://blizzard.cs.uwaterloo.ca/keshav/home/Projects/native.html  native-mode ATM network protocol stack]. Like ATM, this project is defunct.

*While at Cornell, I worked with the CRUSADE group to get high-speed network access to Ithaca. We formed [http://blizzard.cs.uwaterloo.ca/keshav/home/Projects/chug.html CHUG] or Cornell High-Speed User's Group. Our technology supplier, Hybrid systems, went belly up, so that was the end of that.

*Also at Cornell, I worked on redoing the CS website. I put together a set of [http://blizzard.cs.uwaterloo.ca/keshav/home/Projects/req.html requirements] for a departmental website that still seems relevant. This led to the redesigned site, that is still in use with little change.
