SAINT2004 is pleased to announce the following two Tutorials, both of which presents the latest technologies on the hot topics today to participants. Explicit registration is required for Tutorials on the Registration page. Tutorial registration fee includes a copy of the Tutorial text and admission to the Tutorial session.

Tutorial #1 (in English) : Jan.27(Tue) 9:00-12:30

IP-Oriented QoS in the Next Generation Networks: application to wireless networks

Tutorial #2 (in Japanese) : Jan.27(Tue) 13:30-17:00

802.11 Security -- Past, Today, and the Future ---

Tutorial #1 (in English) : Jan.27(Tue) 9:00-12:30

Tutorial Title :

IP-Oriented QoS in the Next Generation Networks: application to wireless networks

Lecturer :

Dr. Pascal Lorenz
Professor at the University of Haute-Alsace

Abstract :

The promising service level agreement to a mobile Internet user is hard to come by, since there may not be enough resources available in some parts of the IP/ATM networks as mobile terminal is moving into. The emerging QoS architectures, differentiated services and integrated services do not consider the network nodes are mobile. QoS mechanisms enforce a differentiated sharing of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different QoS parameters, and to make it possible to charge the users based on
requested quality. Integration of fixed and portable wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity and ubiquitous access in a market where demands on mobile Internet have grown rapidly and predicted to generate billions of dollars in revenue.
The tutorial covers an introduction to QoS in heterogeneous networks, Internet delivery over future wireless networks, the ATM, MPLS, DiffServ, IntServ protocols,  It addresses characteristics of the Internet and its mobility features and how it could guarantee QoS using wireless IP services. It also presents concepts of routing, quality-of-service provisioning and security, baseline architecture of the inter-networking protocols and end to end traffic management issues.

Tutorial #2 (in Japanese) : Jan.27(Tue) 13:30-17:00

Tutorial Title :

802.11 Security -- Past, Today, and the Future ---

Lecturer :

Mr.Motonori Shindo
Chief Technology Officer
Data Control, Ltd.

Abstract :

Most people would agree that wireless network is so useful, while they may be keeping distance from using it due to an intangible fear of its security. Admittedly, early days of 802.11 used to have such security threats. However, those threats has already been addressed by standards like Wi-Fi Protected Access (WPA) and 802.11i, which is becoming one of the major interests not only for enterprise customers but also for service providers and consumers.
This session first reviews the reason why 802.11 wireless network has been given an unenviable label as "insecure" along with the pragmatic threat analysis. It then follows a detailed walk-through over the state of the art wireless security technologies (WPA and 802.11i) to see how these technologies try to solve security problems originally seen in 802.11 wireless LAN.
