ICDT 2011 The Sixth International Conference on Digital Telecommunications Foreword The Sixth International Conference on Digital Telecommunications
held between April 17 and 22 in Budapest, Hungary, continued a series of special events focusing on telecommunications aspects in multimedia environments. The scope of the conference was to focus on the lower layers of systems interaction and identify the technical challenges and the most recent achievements. The conference served as a forum for researchers from both the academia and the industry, professionals, and practitioners to present and discuss the current state-of-the art in research
... d best practices as well as future trends and needs (both in research and practices) in the areas of multimedia telecommunications, signal processing in telecommunications, data processing, audio transmission and reception systems, voice over packet networks, video, conferencing, telephony, as well as image producing, sending, and mining, speech producing and processing, IP/Mobile TV, Multicast/Broadcast Triple-Quadruple-play, content production and distribution, multimedia protocols, H-series towards SIP, and control and management of multimedia telecommunications. High quality software is not an accident; it is constructed via a systematic plan that demands familiarity with analytical techniques, architectural design methodologies, implementation polices, and testing techniques. Software architecture plays an important role in the development of today's complex software systems. Furthermore, our ability to model and reason about the architectural properties of a system built from existing components is of great concern to modern system developers. Performance, scalability and suitability to specific domains raise the challenging efforts for gathering special requirements, capture temporal constraints, and implement service-oriented requirements. The complexity of the systems requires an early stage adoption of advanced paradigms for adaptive and self-adaptive features. On online monitoring applications, in which continuous queries operate in near real-time over rapid and unbounded "streams" of data such as telephone call records, sensor readings, web usage logs, network packet traces, are fundamentally different from traditional data management. The difference is induced by the fact that in applications such as network monitoring, telecommunications data management, manufacturing, sensor networks, and others, data takes the form of continuous data streams rather than finite stored data sets. As a result, clients require long-running continuous queries as opposed to one-time queries. These requirements lead to reconsider data management and processing of complex and numerous continuous queries over data streams, as current database systems and data processing methods are not suitable. Event stream processing is a new paradigm of computing that supports the processing of multiple streams of event data with the goal of identifying the meaningful events within those streams. We take here the opportunity to warmly thank all the members of the ICDT 2011 Technical Program Committee, as well as the numerous reviewers. The creation of such a broad and high quality conference program would not have been possible without their involvement. We also kindly thank all the authors who dedicated much of their time and efforts to contribute to ICDT 2011. We truly believe that, thanks to all these efforts, the final conference program consisted of top quality contributions. Also, this event could not have been a reality without the support of many individuals, organizations, and sponsors. We are grateful to the members of the ICDT 2011 organizing committee for their help in handling the logistics and for their work to make this professional meeting a success. We hope that ICDT 2011 was a successful international forum for the exchange of ideas and results between academia and industry and for the promotion of progress in the field of digital communications. We are convinced that the participants found the event useful and communications very open. We also hope the attendees enjoyed the historic charm of Budapest, Hungary.
