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
