Introduction
During the last decade, there has been a huge growth in the number people using new communication services catalyzed by the developments in the communication technologies industry. On one hand the usage of mobile telephony has tremendously grown and on the other hand the usage of Internet has exploded. These trends have been taking up both in the working environment and in people's private life. We are now within the next development phase, i.e., the mobile industry is expanding from voice services towards data services, and the former Internet related industry is also growing with wireless technologies in the enterprises and at home. Furthermore, the communication technologies are converging with the information technologies, which will create a new information and communication services marketplace. These developments also challenge the respective research communities providing new research opportunities.
During spring 2003 the Internetworking seminar addressed the above described convergence trend from the Internet evolution point of view. The fundamental idea for the seminar was to study and analyze developments in wireless local network environments considering all layers from link layer, network layer and application layer up to business systems. In the mobility perspective, the concept was to dive into such network systems for which the mobility is provided with IP layer protocols and for which unlicensed radio spectrum can be deployed. The selected topic areas included the relevant unlicensed band radio technologies and the most important protocols that are needed to building the necessary service functionality for example to establishing real-time voice communication over the respective wireless connections. The seminar subjects have been clustered into six topic areas.
- Unlicensed band wireless radio technologies (WLAN, Bluetooth - including security).
- IP level mobility - Mobile IPv4/v6 networks (architectures, mobility, security, HIP as a challenger).
- Fast handover in Mobile IPv4/v6 (CAR method, fast handover in IPv4 and IPv6).
- Authentication, Authorization, Accounting - AAA protocols (Radius, Diameter - including mobility support and load balancing).
- Session Initiation Protocol - SIP (signaling, call control, security, application interworking).
- Business systems for Mobile IP based networks (IP telephony services, future of wireless Internet).
This seminar took a broad viewpoint to look for local wireless networks covering issues from unlicensed band wireless radio technologies, IP level mobility, AAA protocols, Session Initiation Protocol, and business systems for Mobile IP based networks. In this framework, the reader is encouraged to consider what are eventually the required technologies to support for the communication technologies evolution - how to fulfill the needs for networking among people.
