Distributed operating systems : concepts and practice.

Doreen Galli uses her considerable academic and professional experience to bring together the worlds of theory and practice providing leading edge solutions to tomorrow's challenges. Distributed Operating Systems: Concepts and Practice offers a good balance of real world examples and the underlying theory of distributed computing. The flexible design makes it usable for students, practitioners and corporate training. This book describes in detail each major aspect of distributed operating systems from a conceptual and practical viewpoint. The operating systems of Amoeba, Clouds, and Chorus™ (the base technology for JavaOS™) are utilized as examples throughout the text; while the technologies of Windows 2000™, CORBA™, DCOM™, NFS, LDAP, X.500, Kerberos, RSA™, DES, SSH, and NTP demonstrate real life solutions. A simple client/server application is included in the appendix to demonstrate key distributed computing programming concepts. This book proves invaluable as a course text or as a reference book for those who wish to update and enhance their knowledge base. A Companion Website provides supplemental information. A broad range of distributed computing issues and concepts: Kernels, IPC, memory management, object-based operating systems, distributed file systems (with NFS and X.500), transaction management, process management, distributed synchronization, and distributed security A major case study of Windows 2000 to demonstrate a real life commercial solution Detail Boxes contain in-depth examples such as complex algorithms Project-oriented exercises providing hands-on-experience Relevant sources including 'core' Weband ftp sites, as well as research papers Easy reference with complete list of acronyms and glossary to aid readability Booknews Written by an academician and professional in the telecommunications industry, this book combines real world examples with the underlying theory of distributed computing, making it useful for students and practitioners alike, as well as for corporate training. Discusses a broad range of distributed computing issues and concepts, using the operating systems Amoeba, Clouds, and Chorus (the base technology for the JavaOS) as examples, and technologies such as the Windows 2000 system as solutions.

This book explores the concepts and practice in distributed computing, and is designed to be useful in helping practitioners and corporate training keep up with software technology that pertains to a majority of all computers and their applications. A two-part approach presents the basic foundation for distributed computing and then expands on these topics to cover advanced distributed operating systems. It describes in detail every major aspect of the topics, and includes relevant examples of real operating systems to reinforce concepts and illustrate decisions that must be made by distributed system designers. Chapters include information on interprocess communication, memory management, concurrency control, and object-based operating systems. More advance material covers distributed process management, file systems, synchronization, and security. For developers and managers active in the client/server technology industry who want to update and enhance their knowledge base.
