New Services such as for Internet data and multimedia applications, have caused a fast growing demand for broadband communications. The fundamental technologies for the integration of these services have been developed in the last decade: optical communications, photonic switching, high speed local area networks, Asynchronous Transfer Mode (ATM), ISDN and B-ISDN, Internet packet networks and mobile communications. The development was possible through the dynamic progress in communication and computer technologies and through worldwide standardization activities within ITU-T, the ATM Forum, the IETF, IEEE, ANSI, ETSI and other bodies. These developments have been supported by research and field trial programmes. Past developments, such as about LAN, Internet or ISDN networking technologies, have shown that it needs a time span of 10 years for a new technology from its research stage to its full application. Broadband Communications is just at its onset for full deployment. It will have a dramatic effect not only on the networking situation but on the whole development of information technology throughout our social and economic life, which is expressed by the conference theme ,The Future of Telecommunications". The Broadband Communications conference series of IFIP WG 6. 2 addresses the fundamental technical and theoretical problems related with these technologies. BC ''98 is the fourth meeting in a series on conferences being held in Stuttgart, Germany. The previous confernces were held in Estoril, Portugal, in 1992, in Paris, France, in 1994, and in Montreal, Canada, in 1996.

Broadband communications is widely recognized as one of the key technologies for building the next generation global network infrastructure to support ever-increasing multimedia applications. This book contains a collection of timely leading-edge research papers that address some of the important issues of providing such a broadband network infrastructure. Broadband Communications represents the selected proceedings of the Fifth International Conference on Broadband Communications, sponsored by the International Federation for Information Processing (IFIP) and held in Hong Kong in November 1999. The book is organized according to the eighteen technical sessions of the conference. The topics covered include internet services, traffic modeling, internet traffic control, performance evaluation, billing, pricing, admission policy, mobile network protocols, TCP/IP performance, mobile network performance, bandwidth allocation, switching systems, traffic flow control, routing, congestion and admission control, multicast protocols, network management, and quality of service. It will serve as an essential reference for computer scientists and practitioners.

Dieser Informatik-Fachbericht ist der Tagungsband der 6. ITG/GI-Fachtagung "Kommunikation in verteilten Systemen", Stuttgart, 22.-24.2.1989, in einer in zweijahrigem Turnus stattfindenden Tagungsreihe. Er enthalt 60 originare Beitrage aus den Gebieten Kommunikationsdienste und -protokolle, Standardisierung, Kommunikations- und Transaktionsmechanismen in verteilten Systemen, Last- und Funktionsverbund in heterogenen Rechnernetzen, Beschreibungs-, Entwicklungsmethoden und -werkzeuge, Technik lokaler Hochgeschwindigkeitsnetze, Mobilfunknetze, Breitband-Vermittlungstechnik auf ATM-Basis, Kopplung heterogener Netze, Netzdiagnose, Verkehrsmessungen, Netzverwaltung (Netzmanagement), Modellierung und Leistungsbewertung, Netzplanung, verteilte Datenbanken, Buroautomatisierung, Fertigungsautomatisierung, Individual-Strassenverkehr. Das Buch vermittelt einen Uberblick uber den Stand der Technik und Wissenschaft auf dem Gebiet der Kommunikation in verteilten Systemen. Es ist der sechste Band in einer in zweijahrigem Turnus stattfindenden Tagungsreihe.

Das Buch gibt zun{chst eine ]bersicht }ber den Kommunika- tionsbedarf verschiedener Teilbereiche in einer rechnerinte- grierten Fertigung (CIM), wobei auf die auszutauschenden Da- ten und die Schnittstellen zu anderen Teilbereichen einge- gangen wird. Dann werden Projekte und Organisation zur Entwicklung offe- ner Kommunikationstechnik in der Fertigungstechnik (CNMA, MAP, EMUG, PROFIBUS, usw.) und die entsprechenden Konzepte und Protokolle (z.B. ISO/OSI-Referenzmodell) vorgestellt. Es folgt ein ]berblick}ber die standardisierten Dienstele- mente (ACSE, FTAM, NMS, ROSE); NMS und die zugeh|rigen Comp- anion Standards werden ausf}hrlich behandelt. Weitverbreitete, firmenspezifische Netze (TCP-IP, DNA, SNA, SINEC) werden ebensobehandelt, wie verschiedene, zur Kopp- lung r{umlich getrennter Fertigungsinseln erforderliche Weiterverkehrsnetze (IDN und ISDN).

Despite the many advances made during the last decade in various aspects of fungal biochemistry, there have been very few volumes devoted to the sub­ ject in recent years. This lack is all the more surprising in view of the increas­ ing use of fungi in gene manipulation studies and in biotechnological ap­ plications, and of the current interest in the biorational discovery of novel agents for the control of fungal pathogens of plants and humans. We hope that this book goes some way to rectifying this situation by providing an up­ to-date account of selected developments in two important areas, namely cell walls and membranes. Topics included in the book concern both yeasts and filamentous fungi. Although the main emphasis is on biogenesis, functional aspects are also discussed, e.g. the role of glycoproteins in recognition of sterols in mem­ branes and of calcium in regulation. Several contributions describe in­ terference with the ''normal'' biochemistry of cell walls and membranes with a view to increasing fundamental knowledge, but also highly relevant to the design of new fungicides and antimycotics. The steadily increasing impact of molecular biology on the study of fungal biochemistry is highlighted throughout.
