Architectural decisions are crucial to the success of any ISP, because they will determine the cost-effectiveness, flexibility, and scalability of the infrastructure used to deliver services. Designing ISP Architectures is a start-to-finish best-practices guide to effective ISP architectural design and implementation. Leading ISP architect and consultant John V. Nguyen uses a running case study to cover every step of the process: formulating design requirements; establishing an architectural model; creating and documenting both logical and physical designs; selecting components; and implementing the architecture you've defined. Nguyen demonstrates how to create platform-independent architectures that can support rapid growth in subscribership, ongoing new product introductions, low-cost operation, and effective management. Along the way, he identifies key tradeoffs and limitations, offering practical guidance architects can use to optimize ISP infrastructure for any marketplace or application portfolio. For every IT architect, consultant, and network professional responsible for designing or implementing ISP architectures.

Service providers are increasingly focused on delivering triple-play bundles that incorporate Internet, video, and VoIP services—as well as multi-play bundles containing even more advanced services. Broadband Network Architectures is the first comprehensive guide to designing, implementing, and managing the networks that make triple-play services possible. Hellberg, Greene, and Boyes present their field-tested industry best practices and objectively evaluate the tradeoffs associated with key up-front architectural decisions that balance the complexities of bundled services and sophisticated traffic policies. Broadband Network Architectures not only documents what is possible on this rapidly changing field of networking, but it also details how to divide Internet access into these more sophisticated services with specialized Quality of Service handling. Coverage includes · An in-depth introduction to next-generation triple-play services: components, integration, and business connectivity · Triple-play backbone design: MPLS, Layer 3 VPNs, and Broadband Network Gateways (BNGs)/Broadband Remote Access Servers (B-RAS) · Protocols and strategies for integrating BNGs into robust triple-play networks · Triple-play access network design: DSLAM architectures, aggregation networks, transport, and Layer 2 tunneling · VLAN-per-customer versus service-per-VLAN architectures: advantages and disadvantages · PPP or DHCP: choosing the right access protocol · Issues associated with operating in wholesale, unbundled environments · IP addressing and subscriber session management · Broadband network security, including Denial of Service attacks and VoIP privacy · The future of wireless broadband: IMS, SIP, and non-SIP based fixed mobile convergence and wireless video

Why the Internet was designed to be the way it is, and how it could be different, now and in the future. How do you design an internet? The architecture of the current Internet is the product of basic design decisions made early in its history. What would an internet look like if it were designed, today, from the ground up? In this book, MIT computer scientist David Clark explains how the Internet is actually put together, what requirements it was designed to meet, and why different design decisions would create different internets. He does not take today's Internet as a given but tries to learn from it, and from alternative proposals for what an internet might be, in order to draw some general conclusions about network architecture. Clark discusses the history of the Internet, and how a range of potentially conflicting requirements—including longevity, security, availability, economic viability, management, and meeting the needs of society—shaped its character. He addresses both the technical aspects of the Internet and its broader social and economic contexts. He describes basic design approaches and explains, in terms accessible to nonspecialists, how networks are designed to carry out their functions. (An appendix offers a more technical discussion of network functions for readers who want the details.) He considers a range of alternative proposals for how to design an internet, examines in detail the key requirements a successful design must meet, and then imagines how to design a future internet from scratch. It's not that we should expect anyone to do this; but, perhaps, by conceiving a better future, we can push toward it.

Architecture and Design for the Future Internet addresses the Networks of the Future and the Future Internet, focusing on networks aspects, offering both technical and non-technical perspectives. It presents the main findings of 4WARD (Architecture and Design for the Future Internet), a European Integrated Project within Framework Programme 7, which addressed this area from an innovative approach. Today’s network architectures are stifling innovation, restricting it mostly to the application level, while the need for structural change is increasingly evident. The absence of adequate facilities to design, optimise and interoperate new networks currently forces a convergence to an architecture that is suboptimal for many applications and that cannot support innovations within itself, the Internet. 4WARD overcomes this impasse through a set of radical architectural approaches, built on a strong mobile and wireless background. The main topics addressed by the book are: the improved ability to design inter-operable and complementary families of network architectures; the enabled co-existence of multiple networks on common platforms through carrier-grade virtualisation for networking resources; the enhanced utility of networks by making them self-managing; the increased robustness and efficiency of networks by leveraging diversity; and the improved application support by a new information-centric paradigm in place of the old host-centric approach. These solutions embrace the full range of technologies, from fibre backbones to wireless and sensor networks.

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 modular This 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.
