Network Performance
Session Chair: Vern Paxton, ACIRI

Awarded Best Student Paper!
EtE: Passive End-to-End Internet Service Performance Monitoring
Yun Fu, Duke University; Ludmila Cherkasova and Wenting Tang, Hewlett-Packard Laboratories; and Amin Vahdat, Duke University

The Performance of Remote Display Mechanisms for Thin-Client Computing

The Joy of Breaking Things
Pat Parseghian, Transmeta

When Transmeta launched the Crusoe microprocessor, how did we assure its compatibility with the x86 architecture? The CPU's layered design poses unique challenges, from the silicon's underlying proprietary architecture through the multiple stages of the Code Morphing Software which executes x86 instructions. This talk will share a testing philosophy and set of practices that can be applied to software products as well as systems or devices.

Hacking in the Kernel
Session Chair: Chuck Cranor, AT&T Labs—Research

An Implementation of Scheduler Activations on the NetBSD Operating System
Nathan J. Williams, Wasabi Systems Inc.

Authorization and Charging in Public WLANs Using FreeBSD and 802.1x
Pekka Nikander, Ericsson Research NomadicLab

ACPI Implementation on FreeBSD
Takanori Watanabe, Kobe University; and Michael Smith, The FreeBSD Project

Developing Portable Applications
Nick Stoughton, MSB Consultants

Nick is a principal with MSB Associates, a small Bay Area consulting firm. He is the USENIX standards liaison, and has been working on developing standards for portable applications (most notably POSIX and LSB) for 10 years. He is head of delegation for the UK to ISO/IEC JTC1/SC22/WG15, Secretary to the IEEE Portable Applications Standards Committee, and Technical Editor for the Itanium Architecture Specific Linix Standards Base document. While not developing standards for portabilty, he is writing portable applications for his clients.

Storage Systems
Elizabeth Shriver, Bell Labs

My Cache or Yours? Making Storage More Exclusive
Theodore Wong, Carnegie Mellon University; and John Wilkes, Hewlett-Packard Labs

Bridging the Information Gap in Storage Protocol Stacks
Timothy E. Denehy, Andrea C. Arpaci-Dusseau, and Remzi H. Arpaci-Dusseau, University of Wisconsin, Madison

Maximizing Throughput in Replicated Disk Striping of Variable Bit-Rate Streams
Stergios V. Anastasiadis, Duke University; and Kenneth C. Sevcik and Michael Stumm, University of Toronto

Technology, Liberty, and Washington
Alan Davidson, Center for Democracy and Technology

The open, distributed, end-to-end architecture of today's Internet is becoming a favorite target of policymakers in the U.S. and around the world. For example, in the wake of the September 11 attacks, new laws and regulations have been proposed in the U.S. to enable greater government monitoring of Internet activity. Concerns about copyright have prompted some to propose government-mandated digital-rights-management security standards. These and other initiatives could directly impact both the architecture of the Internet and the rights of Internet users. This talk will report on the latest Internet security and policy initiatives in Washington and examine their impact on the Internet's architecture and individual liberty.

Analyzing Applications
Session Chair: Jim McGinness, Consultant

Gscope: A Visualization Tool for Time-Sensitive Software
Ashvin Goel and Jonathan Walpole, Oregon Graduate Institute, Portland

Inferring Scheduling Behavior with Hourglass
John Regehr, University of Utah

A Decoupled Architecture for Application-Specific File Prefetching
Chuan-Kai Yang, Tulika Mitra, Tzi-Cker Chiueh, Stony Brook University

Automated System Administration
Steve Traugott, TerraLuna, LLC

Steve helped pioneer the term "Infrastructure Architecture" and has worked toward industry acceptance of this SysAdmin++ career track for the last several years. He is a consulting Infrastructure Architect and publishes tools and techniques for automated system administration. His deployments have ranged from financial trading floors and NASA supercomputers to Web farms and growing startups.

Work-in-Progress Reports
Session Chair: Amin Vahdat, Duke University

Short, pithy, and fun, Work-in-Progress reports introduce interesting new or on-going work, and the USENIX audience provides valuable discussion and feedback. A schedule of presentations will be posted at the conference.

CNN.com: Facing a World Crisis
William LeFebvre, CNN Internet Technologies

On September 11, 2001, Net users flocked to news sites. The unexpected and unprecedented demand quickly drove nearly every news site into the ground, and CNN.com was no exception. What brought our site back up was a tremendous effort of teamwork, fast thinking, and troubleshooting. On September 11, with only 85% availability, we nearly equaled our site's all-time high. Next day, we shattered previous site records. This talk tells the story of the CNN.com team that met an unbelievable user demand.

Work-in-Progress Reports
Session Chair: Amin Vahdat, Duke University

See the General Track (column 1) for a description of this shared session.

Tools
Session Chair: Christopher Small, Sun Microsystems

Simple and General Statistical Profiling with PCT
Charles L. Blake and Steven Bauer, LCS MIT

Engineering a Differencing and Compression Data Format
Phong Vo and David Korn, AT&T Labs

Taking an Open Source Project to Market
Eric Allman, Sendmail, Inc.

What happens when a long-time open source project is converted to a commercial model? Some effects are business-oriented and expected: for example, marketing and sales departments appear. Some are less obvious, involving the way engineering is done. Open source sendmail has been the major MTA since 1982. In 1998, as sendmail neared a "success disaster," a commercial company was formed to develop and support sendmail. The focus of this talk will be on engineering, but business issues will also crop up.

Access Control
Session Chair: Robert Watson, NAI Labs & The FreeBSD Project

Design and Performance of the OpenBSD Stateful Packet Filter (pf)
Daniel Hartmeier, Systor AG

Enhancing NFS Cross-Administrative Domain Access
Joseph Spadavecchia and Erez Zadok, Stony Brook University

Network Management, System Performance Tuning
Jeff R. Allen, Tellme Networks, Inc.

Jeff has been working in the Sysadmin field since 1992. He finds himself drawn to running large, complex systems that serve people who don't want to know they are using a computer (therein lies the complexity). He developed tools for the NOC at WebTV Networks, then moved to Tellme Networks, where today he acts as a bridge between engineering and the NOC, interfaces with the European operations team, and solves tricky problems as they arise.
