It is always confusing, and perhaps inconvenient at times, using generic terms that will mean something to everyone but different things to different people. "High Performance" is one of those terms. High Performance can be viewed as synonymous to High Speed or Low Latency or a number of other characteristics. The interesting thing is that such ambiguity can sometimes be useful in a world where focus shifts quite easily from one issue to another as times and needs evolve. Many things have changed since the first HPN conference held in Aachen, Germany in 1987. The focus then was mainly on Media Access Control (MAC) protocols that allow users to share the high bandwidth of optical fiber. FDDI (Fiber Distributed Data Interface) was making its debut with its amazing 100 Mbps speed. ATM (Asynchronous Transfer Mode) and SONET (the Synchronous Optical Network) were beginning to capture our imagination. What could users possibly do with such "high performance"? Share it! After realizing that the real problems had gradually shifted away from the network media to the periphery of the network, focus also began to shift. Adapter design, protocol implementation, and communication systems architecture began to attract our interest. Networking -not Networks-became the hot issue.

The communication of information is a crucial point in the development of our future way of life. We are living more and more in an information society. Perhaps the more obvious applications are those devoted to distributed cooperative multimedia systems. In both industry and academia, people are involved in such projects. HPN'95 is an international forum where both communities can find a place for dialogues and interchanges. The conference is targeted to the new mechanisms, protocols, services and architectures derived from the need of emerging applications, as well as from the requirements of new communication environments. This workshop belongs to the series started in 1987 in Aachen (Germany), followed by Liege (Belgium) in 1988, Berlin (Germany) in 1991, Liege (Belgium) again in 1992 and Grenoble (France) in 1994. HPN'95 is the sixth event of the series sponsored by IFIP WG 6.4 and will be held at the Arxiduc Lluis Salvador building on the campus of the University of the Balearic Islands in Palma de Mallorca (Spain) from September 13 to 15.

This was the first conference jointly organized by the IFIP Working Groups 6. 2, 6. 3, and 6. 4. Each of these three Working Groups has its own established series of conferences. Working Group 6. 2 sponsors the Broadband Communications series of conferences (Paris 1995, Montreal 1996, Lisboa 1997, Stuttgart 1998, and Hong-Kong 1999). Working Group 6. 3 sponsors the Performance of Communication Systems series of conferences (Paris 1981, Zürich 1984, Rio de Janeiro 1987, Barcelona 1990, Raleigh 1993, Istanbul 1995, and Lund 1998). Working Group 6. 4 sponsors the High Performance Networking series of conferences (Aaren 1987, Liège 1988, Berlin 1990, Liège 1992, Grenoble 1994, Palma 1995, New York 1997, Vienna 1998). It is expected that this new joint conference will take place every two years. In view of the three sponsoring Working Groups, there were three separate tracks, one per Working Group. Each track was handled by a different co chairman. Specifically, the track of Working Group 6. 2 was handled by Ulf Körner, the track of Working Group 6. 3 was handled by Ioanis Stavrakakis, and the track of Working Group 6. 4 was handled by Serge Fdida. The overall program committee chairman was Harry Perros, and the general conference chairman was Guy Pujolle. A total of 209 papers were submitted to the conference of which 82 were accepted. Each paper was submitted to one of the three tracks.

This volume constitutes the refereed proceedings of the International Conference on High Performance Networking, Computing and Communication Systems, and the International Conference on Theoretical and Mathematical Foundations of Computer Science ( ICHCC -ICTMF 2009), held in Sanya, Hainan Island, China, in December 2009. The 15 revised full papers presented were carefully reviewed and selected out of 60 submissions. They range on the various aspects of advances in High Performance Networking, Computing, Communication Systems and Mathematical Foundations.

In the last few years, the world of information networks has undergone significant changes that will revolutionize the future of communications. Data rates have reached the gigabit per second range. Optical fibers have become the transmission medium of choice. Standardization activities have very aggressively produced a set of well established standard for future LANs, MANs and WANs. It has become very difficult for computer and communications professionals to follow these rapidly evolving technologies and standards. High Performance Networks: Technology and Protocols provides a timely technical overview of the start-of-the-art in high performance networking. Chapters cover lightweight protocols, high performance protocol implementation techniques, high speed MAC protocols, optical networks, as well as emerging standards, including ATM, SMDS, B-ISDN, SONET, FCS and HIPPI. Professionals, engineers, and researchers in communications and computers, who need to understand the underlying technologies of high performance (gigabit) networks, will find this volume to be an invaluable reference. The book is also suitable for use as a text for advanced courses on the subject.

Retaining the first edition's technology-centred perspective, this book gives readers a sound understanding of packed-switched, circuit-switched and ATM networks, and techniques for controlling them.

High-Performance Networks for Multimedia Applications presents the latest research on the services and protocols for networks providing the communication support for distributed multimedia applications. The need for end-to-end QoS for these multimedia applications is raising the stakes for a powerful shaping and scheduling in the network adapter. It is also creating a need for new services at the ATM layer, CBR and VBR being augmented by UBR, ABR and GFR which have to be evaluated in the TCP/IP environment of today and tomorrow. With the pressure of all the new technologies available today, the backbone architecture needs to be revisited and the success of the TCP/IP must not eliminate the possibility of adding a native ATM access to it. Most of the research in communication services such as IntServ, DiffServ and Native ATM is driven by the requirements of multimedia systems and this book illustrates the new emphasis by bringing telecommunication and computer communication experts together with application designers. This is particularly true for the security issues also addressed here. Last but not least, modeling techniques and mathematical models are essential to assess the performance of the networks to be built and to evaluate next century scenarios unachievable by a simple scaling of today's solutions. High-Performance Networks for Multimedia Applications is a collection of high quality research papers and the in-depth treatment of the subjects provides interesting and innovative solutions. It is an essential reference for telecommunication and computer experts and QoS-based application designers. It is also a comprehensive text for graduate students in high-perforrnance networks and multimedia applications.

Papers collected here, from a December 2001 workshop held at the University of Central Florida, examine topics related to process coordination and ubiquitous computing. Papers on coordination models discuss areas such as space-based coordination and open distributed systems, global virtual data stru
