Tutorial 1: Management of MPLS-based VPNs

Youngtak Kim (Yeungnam University, Korea)

Abstract : MPLS based VPN is one of the fastest growing services in telecommunications these days, replacing Frame Relay, ATM, and private line services. Although some equipment vendors claim that the MPLS based VPN is easy to provision and manage, it is still a new and complex technology to service providers anyway. It involves multiple routing tables, route redistribution, inter-working with other services, partitioning of network statistics, and so on.

In this tutorial, we will first review the currently available MPLS based VPN technologies with possible deployment scenarios. And then, we will investigate what kind of management tools and options are available for the VPNs, and consider how to use them to manage the VPN networks efficiently. We will discuss the experimental configurations and the performance analysis of MPLS-VPNs with Cisco 7200 series MPLS Routers.

Recommended Audience includes network architects, operations managers and staffs, and researchers in the area of high-speed telecommunications for data services.

The level of the tutorial is intermediate.

 

Tutorial 2: XML Web Services: A Consolidated Overview

Chris Kurt (MicroSoft, USA)

Abstract : The XML Web services protocol stack has evolved dramatically over the past year - from providing basic functionality to the foundation for incredibly rich solutions. This session will provide an overview of each of the Web services specifications, underlying design principles, and the resulting opportunities that are available to developers.

This presentation is targeted at Web services architects and developers who are interested in how to leverage the available Web services protocols to apply them to their own solutions. By the end of the session, each attendee should have introductory-level knowledge of the features available through each specification, and should be able to apply the concepts to their next generation of applications.

 

The level of the tutorial is intermediate - attendees should understand XML and basic Web services concepts.

 

Tutorial 3: QoS Management in the Internet

Marcus Brunner (NEC Europe, Germany)

Abstract : QoS technologies are entering the Internet domain. Among them are IntServ (RSVP), DiffServ and MPLS. The tutorial shortly introduces the basics of IntServ, DiffServ, and MPLS as the underlying QoS technologies. Scalability, manageability, and integration of these technologies are discussed. We believe that the key to get QoS into IP-based networks, lies in the control and management of QoS-enabled networks and transport services. Therefore, the tutorial concentrates on management issues, particularly for the combination of DiffServ and MPLS. Today we are facing several problems in this area, e.g., how do we build edge-to-edge or end-to-end guaranteed services? The tutorial overviews management technologies developed and being standardized in the IETF to provide QoS solutions including SNMP, SNMPconf, COPS, and the Policy Framework. Additionally, we present higher layer management architectures including Bandwidth Brokers/QoS Servers, Policy Servers, QoS routing, and Measurements. Finally, some issues and concepts for inter-domain QoS management will be addressed.

The level of the tutorial is intermediate.

 

Tutorial 4: Ubiquitous System Technology

Shiro Sakata (NEC, Japan)

Abstract : This tutorial aims to give an insight into ubiquitous systems which have been expected to emerge as the next generation computer-and-communication integrated platform for providing versatile consumer-oriented services through overviewing the latest related technologies. First, the definition, scope and the research history of ubiquitous systems originated by Dr. Mark Weiser at XEROX PARC are described as the introduction. Many potential new applications and services provided by ubiquitous systems are also introduced and briefly discussed from the business point of view Second, key technologies, networks, terminals and middleware, which consist of ubiquitous systems are presented in detail. Regarding networks, I will explain the technologies and standardization trends of sensor networks, wireless LAN and their interworking with 3G cellular networks which have a heavy influence over the market penetration of the ubiquitous systems. Regarding terminals, examples of wearable terminals are presented. Middleware involves the whole system architecture, security issues including privacy protection, core functions and protocols related to standardization activities which have been conducted in versatile organization such as IETF, W3C, IEEE802.11, OMA, 3GPP/3GPP2, etc. Content delivery and digital rights management issues are also introduced. Lastly, I will summarize the technology trends, directions and future perspective including business aspects.

Recommended audiences are researchers, engineers (system designers, middleware and application programmers) and marketing people including post-graduate students who have interest in the future technology on computer and communication areas.

The level of the tutorial is Introductory and Intermediate.

The level of the tutorial is introductory to intermediate.

 

Tutorial 6: Wireless LAN: From Technology to Business

Graham Chen (EPAC Technologies, Australia)

Abstract : Wireless LAN technology and product sector is experiencing a phenomenal growth and is becoming one of the shining stars in otherwise gloomy telecommunications industry. With the investment from the semiconductor manufacturers, service providers, IT solution providers, the sector is positioned to be one of the fastest growing segments of the industry.Although the technical standards in wireless LAN have been established, technology is becoming reasonably mature and products are abundant, it remains to be seen whether the technology and products can support a wide range of applications and services. It is further unclear at this time whether these applications and services can turn into profitable business.

•    How to quickly establish a global network deployment model so users can have convenient and ubiquitous access to network
     services and unified user experience.

•    How to introduce value-added applications and services in the WLAN networks.

•    How to establish viable business models to operate these services that deliver real value and economical benefits to businesses
     and consumer users.

This tutorial addresses these challenges. The tutorial first briefly reviews the currently rather chaotic and unstructured deployment of WLAN technology in different market places; we then examine the value added applications and services the network can bring and finally we explore the issues related to the revenue models and business models of these services.

Rather than a WLAN technical tutorial, this tutorial is focused on the deployment and operational models, value-added applications and business models.

It is at an introductory level and it targets IT professionals to help understanding the state of play in technology, applications, services and business issues and challenges in this dynamic market segment.
