Keynote Address

IP Switching: Well Who Cares About the LAN Anymore?"
Dr. Peter Newman, Ipsilon Networks

Synopsis: Remember LANs? Like city states of the middle ages, LANs created small communities of interest where resources were shared. We still have communities of interest -- but after hundreds of years of progress in government and transportation we are no longer restricted to those living in the same town. So it is with networking. I now take it for granted I can get around the local area at high speed -- but how do we open up everywhere else to high-speed, low-latency communication. "On the Information Superhighway the LAN is just your driveway."

We will consider the Great ATM Marketing Machine and look at problems with the current proposals for ATM as the high performance universal network. The difficulties with conventional approaches to IP over ATM will be discussed. IP switching will be proposed as an alternative. Also, we will contrast the gigabit router and the IP switch and discuss scaling IP switching to serve the expanding Internet.

Dr. Newman is a member of technical staff at Ipsilon Networks Inc., Palo Alto, California. He was a staff scientist responsible for ATM systems architecture at Adaptive/NET and is a survivor of the Traffic Management Group of the ATM Forum. In a previous life, he was a research fellow at the Computer Laboratory of the University of Cambridge where he received a Ph.D. for research in ATM switch design in 1989.

Introduction to Distributed Object Programming with CORBA

Presenter: Dr. Doug Schmidt, Washington University

Developing robust, extensible, reusable, and efficient distributed systems and applications is hard. This tutorial presents an overview of distributed object computing based on CORBA 2.0. CORBA is an emerging open standard for distributed object computing that automates many common application development tasks such as service registration, location, and activation, demultiplexing, framing and error-handling, parameter (de)marshalling, and operation dispatching. The tutorial is intended for researchers and developers who plan to use CORBA to design and implement systems such as telecommunication switch management systems, video-on-demand services, network management applications, and personal communication systems.

About the Speaker: Douglas C. Schmidt, Ph.D., is an Assistant Professor of Computer Science at Washington University in St. Louis, Missouri. His research focuses on design patterns, implementation, and experimental analysis of object-oriented techniques for developing high-performance distributed communication systems on parallel processing platforms that run over high-speed networks. Dr. Schmidt is coeditor with Jim Coplien of AT&T Bell Labs for a recent book on Pattern Languages of Program Design and is editor-in-chief of the C++ Report magazine, where he co-authors a column on CORBA with Steve Vinoski, lead architect of HP ORB Plus. In addition, Dr. Schmidt has consulted with Ericsson/GE Mobile Communications, the Motorola IRIDIUM Project, Kodak, and Siemens, developing distributed telecommunications switch monitoring systems and concurrent networking software for distributed medical imaging systems on Windows NT and UNIX multi-processor platforms using CORBA and C++.

Advanced Network Security Concepts: Advanced Intrusion Reponse in a Unix and TCP/IP Environment

Presenter: Mike Newman, En Garde Systems

While much time and research have been devoted to making systems more secure by erecting firewalls, installing patches, using smartcards, encryption, or running a variety of security tools, extremely little effort has been put into the field of intrusion response. While securing systems helps eliminate the most helpless of hackers, it only buys a site a little time until the next vulnerability is found, or the more determined hacker decides he wants to explore a system. When that time is up, how can you tell your site has been had, and what do you do about it? Common wisdom seems to be to shut off the system, reinstall the operating system, call CERT, and wait. This class will teach why an intruder hopes this is what will happen, and give the student a firm grasp on how to perform an investigation, gather evidence for prosecutorial purposes, find and eliminate backdoors left behind by the intruder, determine what information has been compromised, coordinate with other sites, deal with law enforcement, and, hopefully in the end, take a byte out of crime.

This will be an advanced tutorial. Fundamentals of security policy and knowledge of tools and techniques is assumed. Also, a good understanding of Unix, TCP/IP, and their associated services and protocols is required.

Advanced Network Design Using Measurements, Simulation, and Analytical Techniques

Presenter: Dr. Moshe Zukerman, Monash University

This tutorial will provide the network designer with understanding of the principles of state-of-the-art network design methods. It will provide answers to common questions such as: What should I measure in my network? How accurate are various commercial tools? How can tools and measurements be used for efficient dimensioning? What are the critical issues and the fundamental principles in the design of high-speed networks?

High-Speed Networking Technologies For the Enterprise and For Access from Home

Presenter: Dr. Raj Jain, Ohio State University

This tutorial will cover recent high-speed networking technologies. Both high-speed access from home and high-speed communications in the enterprise will be covered. For enterprise networking, we will discuss ATM, Fast Ethernet, Gigabit Ethernet, 100Base-VG, FDDI, and Fiber Channel. The concepts of switched LANs, virtual LANs, and IP switching will be explained. For high-speed access from home, ADSL, HDSL, Cable Modems, and Hybrid Fiber-Coax will be presented.

About the Speaker: Raj Jain is a Professor of Computer Information Sciences at The Ohio State University in Columbus, Ohio. Since 1978, he has been an active participant in many networking standards and industry forums. Currently he is very active in the Traffic Management working group of ATM Forum and has influenced its direction considerably.

He is the author of Art of Computer Systems Performance Analysis, published by Wiley and FDDI Handbook: High-Speed Networking with Fiber and Other Media published by Addison Wesley. He is an IEEE Fellow, an ACM Fellow, an ACM Lecturer, and an IEEE Distinguished Visitor. For further information, please see http://www.cis.ohio-state.edu/~jain/.

Panel Sessions

High-Speed Networking in the Enterprise: Which Way?

Panel Chair: Dr. Raj Jain, Ohio State University
Panelists: Joseph Skorupa, Fore Systems; Dr. Peter Newman, Ipsilon Networks

Over the past few years, a number of new technologies have been developed for high-speed networking, including ATM, Fast Ethernet, Gigabit Ethernet, 100Base-VG, FDDI, Fiber Channel, and so on. Many of these are for the desktop, while others are for the campus backbone and beyond. The panelists will debate the future of these technologies. Are the technolgies living up to their initial promise? Are we converging towards one technology end-to-end? If so, which one? If not, what should the users be planning for their enterprise?

Why and How to Employ Measurements, Simulation, and Analytical Techniques to Improve Your Network Performance

Panel Chair: Dr. Frank Huebner, Bellcore
Panelists: Dr. Len Forys, Forys Inc.; Dr. Moshe Zukerman, Telstra; Dr. Elias Drakopoulos, Bell Labs, Lucent Technologies; Dr. Frederick Scholl, Monarch Information Networks Inc.

The purpose of the panel is to inform the audience about why performance evaluation using measurements, simulations, and analytical techniques can save anyone who operates networks money by enabling him to manage the network more efficient, effective, and deliver a higher user-perceived quality of service. We will also discuss how to use the above mentioned techniques and how to combine them, and where the limitations are.

Self-Defense on the Information Superhighway

Panel Chair: Barbara Fraser, CERT Coordination Center

Organizations are actively connecting their LANS to each other and to the Internet. Many parts of this information superhighway are nothing more than frontier trails where the protection of your "electronic life and property" depends largely on the defensive actions taken by you and the administrators of your networks and systems. This panel session will present the current threats and vulnerabilities of this environment, and discuss corresponding technologies and practices that can be applied to minimize the threat. The panel will also explore emerging technologies that promise a better tomorrow.
