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

Are you a network designer or architect? If you are, then this book is for you! Authors Russ White and Denise Donohue, have done an outstanding job of writing a book examines the intersection of flow, time and people, across two broadly competing and more widely understood realms: business and technology. Authors White and Donohue, begin by discussing what information you need to determine business requirements, and how to gather that information. Then, the authors examine how to apply business knowledge in creating the network blueprint. They continue by examining at a high level, how you can use business knowledge to create a custom network design that helps support or even improve the way a company does business. Then, the authors introduce models, by describing how protocols interact to transport data across a network, including the well known ISO seven-layer model, and the lesser known four-layer Department of Defense model; as well as, the little known iterative model. They then discuss the crucial questions that every network designer needs to be able to answer about every link type, and why each of these questions matters. Next, the authors show you how to modularize, and then consider the trade-offs between modularization and network efficiency. They continue by covering hierarchical design; considering what it is; and, why hierarchical design works the way it does. Then, the authors look at redundancy, because it is the primary that is used to build resilience into a network. They then explore the Observe, Orient, Decide, Act loop; and, how it applies to the never-ending cycle of attack and defense. Next, the authors show you how to minimize the pain of network management, while maximizing the gain. They continue by defining what a tunnel is; as well as, a need to consider the underlying questions any network designer or architect should ask about any virtualization technology. Then, the authors deal with the question of which routing protocol is best: Exposing the questions network architects need to ask in order to answer that question, rather than providing a one size fits all solution. They then try to make complexity a little less fuzzy. Next, the authors will consider some hard and fast realities about device mobility, primarily focused on how and where to hold the state needed to make mobility work. They continue by examining cloud computing, with a look back through the history of information technology, so that they can put it all in context. Then, the authors discuss what an SDN is, and present one specific taxonomy, or method of classifying SDNs. Finally, they give you a solid theoretical understanding of the problems onto which you can lay specific solutions. For those readers who are very much tech savvy, this excellent book probably feels like it is too much about business, and not much about technology. Nevertheless, this is going to be the nature of a great book that covers such a broad cross-section of ideas that are each very deep in their own right.
