The design and implementation of the 4. 4BSD operating system

This book describes the design and implementation of the BSD operating system - previously known as the Berkeley version of UNIX. Today, BSD is found in nearly every variant of UNIX, and is widely used for Internet services and firewalls, timesharing, and multiprocessing systems. Readers involved in technical and sales support can learn the capabilities and limitations of the system; applications developers can learn effectively and efficiently how to interface to the system; systems programmers can learn how to maintain, tune, and extend the system.Highlights: * Details major changes in process and memory management * Describes the new extensible and stackable file system interface * Includes an invaluable chapter on the new network file system * Updates information on networking and interprocess communication Written from the unique perspective of the system's architects, this book delivers the most comprehensive, up-to-date, and authoritative technical information on the internal structure of the latest BSD system.

Written from the unique perspective of the system's architects, this book delivers the most comprehensive, up-to-date, and authoritative technical information on the internal structure of the latest BSD system.

As in the previous book on 4.3BSD (with Samuel Leffler), the authors first update the history and goals of the BSD system. Next they provide a coherent overview of its design and implementation. Then, while explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing the system's facilities. As an in-depth study of a contemporary, portable operating system, or as a practical reference, readers will appreciate the wealth of insight and guidance contained in this book.

Highlights of the book:

• Details major changes in process and memory management
• Describes the new extensible and stackable filesystem interface
• Includes an invaluable chapter on the new network filesystem
• Updates information on networking and interprocess communication

An authoratative guide to the 4.4 BSD internal structure (from the interface to kernels to the hardware), this book details concepts, algorithms, data structures, plus the major changes in process and memory management as well as the new extensible and stackable filesystem interface with in-depth information on the new network filesystem. This book is ideal for systems programmers, administrators, and application developers. Technical and sales support professionals will find vital information on the capabilities of 4.4BSD. Applications developers will pick up tips on interfacing with the system, while systems programmers can learn how to better maintain, tune, and extent the system.
