Quality of Service for multimedia applications in UMTS/WLAN networks

Peter Altenbernd, Siemens Business Services, Simon Schneider, Nokia Research Center, Michael Ditze, Paderborn University/C-LAB


Abstract: The goal of this full day tutorial is to give a broad overview of QoS aspects for multimedia applications in modern wireless networks, focusing on UMTS and WLAN (IEEE 802.11) technologies as well as heterogeneous combined approaches. Hence, it will introduce video streaming compression techniques as a core component for multimedia premium services and identify respective QoS parameters. The term QoS will be defined and Mobile IP along with respective QoS models for network traffic control (Differantiated Services, Integrated Services) and real-time information processing (real-time systems, real-time scheduling) will be introduced. The main part of the tutorial will examine how these models are currently adapted to 3G and WLAN networks. The QoS concepts and architectures that will enable reliable premium multimedia services, are covered. Therefore, it will also give a broad overview of the relevant principles and architectures of UMTS and WLAN from both, the industrial and research point of view. It will also try to answer some basic questions of why and where UMTS and wireless local area networks can be used and whether UMTS and WLAN are competing or complementary technologies. By featuring two presenters with industrial background from leading-edge companies Nokia and Siemens and one presenter with academic background from Paderborn University, this tutorial addresses industrial practical topics complemented by scientific research background. The target audience for this tutorial includes both interested academics as well as technology decision makers from the Telecommunications and Service Provider business, who want to gain deeper understanding about QoS aspects of future wireless services.

Design and Analysis of Real-Time and Multimedia Networking Systems

Albert M. K. Cheng, University of Houston, USA


Abstract: Multimedia and real-time systems are becoming increasingly popular in a variety of applications. These applications include group collaboration, remote medical diagnosis/treatment, conferencing systems, on-demand video services, and distance/remote sensing, learning, and monitoring. One major requirement for the implementation of such systems is the efficient transmission of multimedia information (video, image, audio, text) over a communication or computer network. Another major requirement is the bounded-time access and storage of multimedia information. Current image (JPEG) and video (MPEG) transmission techniques using precise or progressive algorithms work well if sufficient processing power, network bandwidth, and transmission time are available, but do not adapt properly to a reduction in one or more of these resources. A precise algorithm must be executed in its entirety before an output can be produced whereas the execution of an imprecise algorithm can be ended at any time prior to normal completion and a usable output can still be produced. Furthermore, the correctness of an imprecise algorithm is monotone increasing. The more resources such as time are spent in the imprecise algorithm's execution, the more accurate is the obtained output. However, current transmission algorithms are not in the proper imprecise form and must be significantly modified to implement the imprecise approach.  This tutorial presents an application of imprecise computation techniques to yield a balanced tradeoff between the quality of the multimedia information transmitted and the available resources for transmission in a networked environment. It also describes real-time scheduling and routing techniques for networks with multimedia applications. Proxy caching for web servers are also discussed. Then the tutorial evaluates and assesses the practicality of the available techniques and tools for building the next generation of real-time and multimedia networking systems. Topics covered include the real-time aspects of multimedia systems; and the analysis and verification techniques/tools based on schedulability analysis, model checking, Statechart/Statemate, Modechart, timed automata, timed Petri nets, process algebra, real-time temporal logic, and semantic rule-based analysis.

Developing Enterprise Web Services and Applications

Sandeep Chatterjee, FoundationalNet, Inc.


Abstract: The next stage in the evolution of enterprise applications will be based on Web services. Web services are pieces of application functionality that are exported through a set of standard application programming interfaces (APIs), and allow applications to be constructed by locating and binding to the exported functionality. More interestingly, multiple Web services can be coordinated together in unique combinations in an Internet application to implement value-added services for users. In this tutorial, we describe the design, development, deployment, and maintenance of Internet applications based on Web services. We also describe the emerging mobile Internet environment, the unique issues inherent to these environments, and the challenges in developing mobile applications based on loosely coupled Web services. In addition to a broad coverage of the fundamental topics, industry standards, and technologies (e.g., Java, J2EE, application servers, XML, SOAP, WSDL, UDDI) underlying the development of Web services and applications based on Web services, the tutorial will provide practical, step-by-step instruction for the development and deployment of enterprise-class Web services and applications based on standard Java 2 Enterprise Edition (J2EE) application servers and SOAP servers. We also touch on .Net technologies in support of enterprise Web services.
