Fred Douglis is the Department Head of the Distributed Systems Research Department in AT&T Labs -- Research. His research interests include the World-Wide Web, load sharing, mobile computing, and file systems.



Web Caching and Performance

With Ramón Cáceres, Anja Feldmann, Gideon Glass, and Michael Rabinovich, he has been working on web cache performance issues. See ``Web Proxy Caching: The Devil is in the Details .'' Workshop on Internet Server Performance, June 1998. Also see a revised and extended version, submitted for publication. I just submitted a position paper on Resource Updates on the Web to the W3C Workshop on Web Characterization .

HTTP Deltas and Compression

With Gaurav Banga, Anja Feldmann, Bala Krishnamurthy, Jeff Mogul (Digital Western Research Lab), and Misha Rabinovich, he has been looking into methods to improve WWW performance via delta-encoding or compression. This has led to prototype implementation of delta-encoding and a more recent trace-driven study of potential benefits that appeared in Sigcomm'97.

AIDE

The AT&T Internet Difference Engine (AIDE) is a tool that ``remembers'' HTTP pages for users and then highlights changes to subsequent versions of the page. An article on AIDE appeared in World Wide Web, January 1998. The HtmlDiff component of AIDE is now available for noncommercial use.

Teaching

[PUCS] He taught distributed computing at Princeton University in the fall of 1996. Lecture notes from that course are available and may be used, with acknowledgement, for noncommercial purposes.

Recruiting

He is a recruiter for U.C. Berkeley Computer Science.

Professional Activities

[IEEE Computer Society] Douglis is the chair of the IEEE Computer Society's Technical Committee on Operating Systems through December, 1998. He's chair of a new Task Force on Internetworking (TFIW), which will hopefully become a technical committee in November 1998. He coauthored a column for Computer's Technical Activities Forum, which might appear in November or December 1998. He's on the steering committee for TCOS's HOTOS conference, of which he was general chair back in 1994, the TFIW/TCOS WMCSA'99 mobile computing workshop, and several other events currently being organized. He is a Senior Member of the IEEE.

[www8] He is a program subcommittee chair for the 8th International World Wide Web Conference (1999). He was also on the program committee for the 7th International World Wide Web Conference (1998). When he went to Australia, the only thing he had time for outside the conference was to make a new friend. (One of them needs to go on a diet.)

The USENIX Association He will be the program chair for the Second USENIX Symposium on Internetwork Technologies and Systems, in 1999. He was also the program chair for the 1998 USENIX Technical Conference.

[WWW Journal] He is on the editorial board of World Wide Web, and is the guest editor for a special issue on World Wide Web Characterization and Performance Evaluation, to appear in 1999.

He was on the program committee for a Workshop on Internet Server Performance, which was held in conjunction with Sigmetrics98, and will be on the program committee for WISP'99 (also in conjunction with Sigmetrics99). Some time ago, he was on the program committees for ICDCS-14 and the 4th Symposium on Experiences with Distributed and Multiprocessor Systems.
