In Patterns in Network Architecture, pioneer John Day takes a unique approach to solving the problem of network architecture. Piercing the fog of history, he bridges the gap between our experience from the original ARPANET and today’s Internet to a new perspective on networking. Along the way, he shows how socioeconomic forces derailed progress and led to the current crisis. Beginning with the seven fundamental, and still unanswered, questions identified during the ARPANET’s development, Patterns in Network Architecture returns to bedrock and traces our experience both good and bad. Along the way, he uncovers overlooked patterns in protocols that simplify design and implementation and resolves the classic conflict between connection and connectionless while retaining the best of both. He finds deep new insights into the core challenges of naming and addressing, along with results from upper-layer architecture. All of this in Day’s deft hands comes together in a tour de force of elegance and simplicity with the annoying turn of events that the answer has been staring us in the face: Operating systems tell us even more about networking than we thought. The result is, in essence, the first “unified theory of networking,” and leads to a simpler, more powerful—and above all—more scalable network infrastructure. The book then lays the groundwork for how to exploit the result in the design, development, and management as we move beyond the limitations of the Internet.

The Art of Network Architecture by Russ White,Denise Donohue Pdf
The Art of Network Architecture Business-Driven Design The business-centered, business-driven guide to architecting and evolving networks The Art of Network Architecture is the first book that places business needs and capabilities at the center of the process of architecting and evolving networks. Two leading enterprise network architects help you craft solutions that are fully aligned with business strategy, smoothly accommodate change, and maximize future flexibility. Russ White and Denise Donohue guide network designers in asking and answering the crucial questions that lead to elegant, high-value solutions. Carefully blending business and technical concerns, they show how to optimize all network interactions involving flow, time, and people. The authors review important links between business requirements and network design, helping you capture the information you need to design effectively. They introduce today’s most useful models and frameworks, fully addressing modularity, resilience, security, and management. Next, they drill down into network structure and topology, covering virtualization, overlays, modern routing choices, and highly complex network environments. In the final section, the authors integrate all these ideas to consider four realistic design challenges: user mobility, cloud services, Software Defined Networking (SDN), and today’s radically new data center environments. • Understand how your choices of technologies and design paradigms will impact your business • Customize designs to improve workflows, support BYOD, and ensure business continuity • Use modularity, simplicity, and network management to prepare for rapid change • Build resilience by addressing human factors and redundancy • Design for security, hardening networks without making them brittle • Minimize network management pain, and maximize gain • Compare topologies and their tradeoffs • Consider the implications of network virtualization, and walk through an MPLS-based L3VPN example • Choose routing protocols in the context of business and IT requirements • Maximize mobility via ILNP, LISP, Mobile IP, host routing, MANET, and/or DDNS • Learn about the challenges of removing and changing services hosted in cloud environments • Understand the opportunities and risks presented by SDNs • Effectively design data center control planes and topologies

You can use this book to design a house for yourself with your family; you can use it to work with your neighbors to improve your town and neighborhood; you can use it to design an office, or a workshop, or a public building. And you can use it to guide you in the actual process of construction. After a ten-year silence, Christopher Alexander and his colleagues at the Center for Environmental Structure are now publishing a major statement in the form of three books which will, in their words, "lay the basis for an entirely new approach to architecture, building and planning, which will we hope replace existing ideas and practices entirely." The three books are The Timeless Way of Building, The Oregon Experiment, and this book, A Pattern Language. At the core of these books is the idea that people should design for themselves their own houses, streets, and communities. This idea may be radical (it implies a radical transformation of the architectural profession) but it comes simply from the observation that most of the wonderful places of the world were not made by architects but by the people. At the core of the books, too, is the point that in designing their environments people always rely on certain "languages," which, like the languages we speak, allow them to articulate and communicate an infinite variety of designs within a forma system which gives them coherence. This book provides a language of this kind. It will enable a person to make a design for almost any kind of building, or any part of the built environment. "Patterns," the units of this language, are answers to design problems (How high should a window sill be? How many stories should a building have? How much space in a neighborhood should be devoted to grass and trees?). More than 250 of the patterns in this pattern language are given: each consists of a problem statement, a discussion of the problem with an illustration, and a solution. As the authors say in their introduction, many of the patterns are archetypal, so deeply rooted in the nature of things that it seemly likely that they will be a part of human nature, and human action, as much in five hundred years as they are today.

The Real Internet Architecture by Pamela Zave,Jennifer Rexford Pdf
"This book offers a description of the architecture of the Internet as it actually exists now. It is a revolutionary description, based on a completely new model of network architecture, explaining how the Internet has evolved from its origins and how it is still evolving, and exposing previously unarticulated patterns and trends in network architecture. Essentially all discussion of the Internet is still dominated by the "classic" (five-layer) model put forth by its originators. This model is so outdated that it is a hindrance to understanding Internet evolution, as well as to teaching and doing effective research on networking. This book replaces it with a new model of networking called "compositional network architecture." This model has been formalized, but the book does not use the formal model; rather, the book relies on the model's accuracy and precision as a foundation for a convincing informal explanation, accessible to a much broader audience than a formal model would be (the formal model will be available on a companion website, along with teaching material). Many scholars and practitioners, seeing the Internet only through the lens of the classic Internet architecture, complain that the Internet has not evolved past its original architecture. Compositional network architecture is a general model for describing many architectures, and it shows clearly how the Internet has evolved since the early 1990s, and how it continues to evolve. Though the book is based on a conceptual model and is therefore a relatively abstract treatment, it is illustrated with hundreds of contemporary Internet examples, so there is no lack of concrete detail or grounding in reality. Compared to older works on networking, the book is also more concerned with network services-how a network helps users communicate. This is a natural outgrowth of the Internet as subject matter. Performance and scalability are the usual themes of Internet literature, as they were certainly the most important challenges of the Internet's early years. Since the 1990s, however, progress on performance and scalability has been steady and incremental. The major motivation for Internet evolution since then has been the need for enhanced services, including mobility, multicast, security, privacy, reliability, and support for content distribution, and the book will engage with these themes. It will serve as a reference for anyone dealing with internet architecture, and as a graduate textbook for networking courses"--
