Variable QoS from Shared Web Caches: User-Centered Design and Value-Sensitive Replacement

by Terence Kelly, Sugih Jamin, and Jeffrey K. MacKie-Mason, University of Michigan
MIT Workshop on Internet Service Quality Economics, 2-3 December 1999, Cambridge, MA
12 November 1999, PostScript (published version), 14 pages.
This will eventually appear as a chapter in the MIT Press book, Internet Services [ISBN 0-262-13448-9]. However this book has taken aeons to publish. As of September 2005, it is listed in both MIT Press and Amazon as "September 2004." The publicity blurb about "clarifying the issues for a post-Internet bubble age" is particularly entertaining, considering that the entire contents of the book were finalized years before the bubble burst.

Biased Replacement Policies for Web Caches: Differential Quality-of-Service and Aggregate User Value

by Terence Kelly, Yee Man Chan, Sugih Jamin, and Jeffrey K. MacKie-Mason, University of Michigan
Fourth International Web Caching Workshop, San Diego, California, 31 March - 2 April 1999.
24 March 1999, PostScript (published version), 10 pages.
We present a simple generalization of least-frequently-used (LFU) replacement that is sensitive to varying levels of server valuation for cache hits. Through trace-driven simulation we show that our algorithm delivers a reasonable QoS relationship: higher byte hit rates for servers that value hits more. We furthermore demonstrate that our algorithm delivers higher aggregate value to servers than LRU or LFU.

Presentations

Market-Oriented Data Distribution for Information System Survivability

RAND Corporation, Santa Monica, California
1 September 1998, Handouts, compressed PostScript, 5 pages
This talk reviews the use and misuse of markets in the military, and suggests that automated software markets embedded within military information systems might enhance survivability by enabling large-scale data replication and by providing dynamic resource allocation. The talk also escribes a market-based Web cache management system and presents the results of a preliminary investigation of its performance via trace-driven simulation.

Extending the ALLONS Traffic Control Algorithm to Systems of Signalized Intersections

(13 January 1998, HTML (some figures missing) and PostScript, 23 pages)
Explores extensions of a single-intersection traffic signal control algorithm to systems of multiple intersections. The control problem is formulated as the search of a tree-structured decision network, and I consider both traditional search algorithms (depth-first search, A*) as well as innovative recent generalizations of A* from the operations research literature.

Dr. T: A Communications Infrastructure for Distributed Interactive Applications

(11 December 1997, HTML (some figures missing) and PostScript, 39 pages)
Dr. T is a simple communications infrastructure designed to support distributed interactive applications such as networked games, chat programs, and shared whiteboard systems. It hides from application programmers the details of networking software and presents a very simple abstraction of distributed process group input. On campus-sized WANs Dr. T supplies inputs to process group members frequently enough to keep pace with a 30 Hz screen refresh rate. This paper describes the design & implementation of Dr. T and illustrates the use of the system with a sample "game" application. All of the source code described in this paper is presented.

ATIS at Rush Hour: Adaptation and Departure Time Coordination in Iterated Commuting

(18 May 1997, HTML and PostScript, 54 pages)
Advanced Traveler Information Systems (ATIS) enable motorists to use fundamentally new strategies when selecting departure times in morning commuting. What are the effects of these new strategies on overall traffic system performance? Just as safety devices such as air bags and anti-lock brakes can have counter-intuitive effects when deployed on a large scale, it is conceivable that ATIS systems may degrade system-level traffic network performance. This paper compares the effects of departure time decisionmaking strategies that unaided motorists may employ with strategies that require ATIS-like technologies. Includes appendices containing annotated listings of all simulation code used in this set of experiments. See also "Driver Strategy and Traffic System Performance" below.

Further Computational Results on Fastest Paths in Stochastic Time-Dependent Networks

(18 May 1997, HTML and PostScript, 15 pages)
Dijkstra's algorithm and other dynamic-programming methods cannot be used to compute fastest paths in transportation networks where travel times are both stochastic and time-dependent. Michigan professor Michael Wellman developed an algorithm capable of computing fastest paths in such networks. This paper presents computational evidence suggesting that the time required by Wellman's algorithm increases sub-exponentially as a function of network size on a class of randomly-generated transportation networks.

sniffle project report

(14 September 1995, HTML and PostScript, 75 pages)
sniffle is a "Simple Networked Interface to the Full Functionality of Lab Equipment." It's a flexible, extensible, general system I developed during the summer of 1995 for Professor Michael Littman of Princeton's Mechanical and Aerospace Engineering Department. sniffle allows any Web client to control nearly the full functionality of an Analog Devices RTI-815 I/O board mounted in the Web server computer and a Tektronix 222 digital oscilloscope connected to the server via a serial port. See the sniffle home page. for a variety of documents related to the project, e.g. a "hype sheet" briefly describing the system. sniffle has been in continuous use since September 1995 on a Win3.1 platform and is being ported to Win95 in January 1998. A number of projects have been built on top of it, and the core of the system has been extended. A research group at the University of Colorado has added the sniffle documentation to its reading list.
