Tutorial 1: Prosperous De Facto Communication Technologies outside Academic Societies

Tohru Asami (University of Tokyo)

Abstract : The rapid development of new communication services in these days has put technologies into the markets before investigations or researches in academic societies or in standard bodies like ITU. Among them, this tutorial picks up two de-facto technologies in Japan, Ether over Ether and Mobile IP, and introduces their specifications and services in brief. They have four points in common: they are commercially successful, designed by operating divisions, and also key technologies for next-generation communication services such as NGN (Next Generation Network) or FMC (Fixed Mobile Convergence), but have few contributions directly from academic people. The rapid development, as well as competition to keep the prices down, will make commercial divisions introduce new but immature vendor-specific technologies, which may have some type of scale-up problem. Such flaws might be expected beforehand if academic societies and standard bodies worked well，but there are huge discrepancies between commercial needs and standards as well as academic papers. During the course of solving such urgent problems in operating divisions, de facto technologies may be born as a last resort. This crisis of commercial divisions must also be considered as the one for academic societies and standard bodies. Roles of these entities should be brushed up for development of next-generation communication services.

Tutorial 2:IP Mobility: Trend and Perspectives

Eun Kyoung Paik (Advanced Technology Lab. KT)

Abstract : With the demand for 4G all-IP networks, IP mobility technology has been standardized in the IETF. IP mobility does not only provide common mobility support over heterogeneous access networks, but also provisions service convergence over the Internet. Recently, the introduction of mobile WiMAX accelerates the deployment of IP mobility. This tutorial addresses the standardization trend, deployment issues, and future perspectives of the IP mobility support. Firstly, this tutorial begins with the overview of IP mobility. Then, it investigates the schemes for seamless IP mobility. Fast mobility and multihoming schemes are analyzed for this purpose. Finally, it concludes with latest standardization trend in the IETF and perspectives. IP over IEEE 802.16 networks and IPv6 over IEEE 802.15.4 networks are illustrated as examples.

Tutorial 3: Web2.0, a Window to the Future

Sanku Jo (KT, Korea)

Abstract : Web2.0 is a window to sense paradigm shift triggered by the Internet. Web2.0 was about web technologies and businesses. However, it has been turned out to be about people, social architecture, and politics as well as about businesses. Rule and place of games are dramatically changing as much as the only constant is the innovation empowering people. Web2.0 is the icon of new age. Consequently, we will try to have insight on web2.0 and its impact in this tutorial.

Tutorial 4: Standardization Activities of NGN

Takashi Egawa (NEC, Japan)

Abstract : International standardization of the NGN (Next-Generation Network) is underway in ITU-T by involving various standards organizations, e.g., ETSI TISPAN and 3GPP/3GPP2. Its aim is to build managed IP networks that guarantee QoS (Quality of Service) and security through resource management and strict user authentication, to replace the telephone networks, the traditional communication infrastructure, and to make a new one suitable for the future applications such as IPTV. This tutorial introduces standardization trends, its achievement, hot topics and its milestones. It also describes the concept of dependability that NEC proposes, and summarizes its activities at ITU for the realization of this concept.
