A new way to understand the architecture of today’s Internet, based on an innovative general model of network architecture that is rigorous, realistic, and modularThis book meets the long-standing need for an explanation of how the Internet's architecture has evolved since its creation to support an ever-broader range of the world's communication needs. The authors introduce a new model of network architecture that exploits a powerful form of modularity to provide lucid, insightful descriptions of complex structures, functions, and behaviors in today’s Internet. Countering the idea that the Internet’s architecture is “ossified” or rigid, this model—which is presented through hundreds of examples rather than mathematical notation—encompasses the Internet’s original or “classic” architecture, its current architecture, and its possible future architectures.For practitioners, the book offers a precise and realistic approach to comparing design alternatives and guiding the ongoing evolution of their applications, technologies, and security practices. For educators and students, the book presents patterns that recur in many variations and in many places in the Internet ecosystem. Each pattern tells a compelling story, with a common problem to be solved and a range of solutions for solving it. For researchers, the book suggests many directions for future research that exploit modularity to simplify, optimize, and verify network implementations without loss of functionality or flexibility.

Subtitled "The Work of Michael Jackson," this book spans the career of one of software engineering''s most important figures. Half the chapters are an anthology of Jackson''s past writings, exemplifying the clarity, wisdom, and wit for which he is so well known. The other half of the book is new: Jackson and his colleagues gives their latest views on requirements, specifications, design, problem frames, and programming methods. Although many people have observed that software development should be more of an engineering discipline, few have drawn from the wider engineering literature more deeply or usefully than Jackson. Because of his work, many software engineers have a better perspective on their software and the real world it is intended to serve.

FME 2001 is the tenth in a series of meetings organized every eighteen months by Formal Methods Europe (FME), an independent association whose aim is to stimulate the use of, and research on, formal methods for software development. It follows four VDM Europe Symposia, four other Formal Methods Europe S- posia, and the 1999 World Congress on Formal Methods in the Development of Computing Systems. These meetings have been notably successful in bringing - gether a community of users, researchers, and developers of precise mathematical methods for software development. FME 2001 took place in Berlin, Germany and was organized by the C- puter Science Department of the Humboldt-Universit¨at zu Berlin. The theme of the symposium was Formal Methods for Increasing Software Productivity. This theme recognizes that formal methods have the potential to do more for industrial software development than enhance software quality { they can also increase productivity at many di erent points in the software life-cycle. The importance of the theme is borne out by the many contributed papers showing how formal methods can make software development more e cient. There is an emphasis on tools that nd errors automatically, or with relatively little human e ort. There is also an emphasis on the use of formal methods to assist with critical, labor-intensive tasks such as program design and test-case generation.
