Patterns in Network Architecture takes a fresh look at the patterns that appear in the varying protocols used in networks, across all layers and applications. This revolutionary book peels back a new way to view network architectures, avoiding many of the ornate and cumbersome constructions required in the past and generates much simpler and more powerful constructs.

This book does not claim to propose a "new paradigm" or "a whole new way of looking at networking", nor does it claim that this theory accommodates everything that has been done before. This is a book about architecture. Not a radically new architecture, but one based on the previous experiences and using many of the components of previous architectures.

By looking at decisions that were made over the years, - the reader learns about the levels of the OSI and the protocols that traverse them. Comparing problems then and now, and observing patterns that are common to the layers and protocols the reader takes a analytic journey of the stack - which yields startling conclusions about the current view network architecture. This book is authored by one of the members in charge of the OSI Reference Model, Naming and Addressing and upper layer architecture. John Day has spent the past 20 years looking at problems and seeing different solutions, and in Patterns in Network Architecture had advanced a groundbreaking work of theory.
