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

The explosion of internet-enabled devices in home networks, such as smartphones, tablets, laptops, and internet-protocol TV (IPTV), threatens to choke current wire-line and wireless broadband-access speeds and demands an order-of-magnitude improvement. Furthermore, the heterogeneous nature of these devices' traffic requires intelligent management of the access networks' quality-of-service (QoS) guarantees, especially for video traffic. This dissertation investigates the redesign of broadband-access architectures by using limited cooperation to deliver an order-of-magnitude increase in data-rates, and by using cross-layer scheduling and pre-caching protocols to balance the QoS requirements of both data and video traffic. The first part of the dissertation investigates the gains of cooperative communication systems when only a limited number of receivers cooperate. The cooperation benefits in terms of data-rate gains can diminish significantly in such limited cooperation scenarios by using the state-of-the-art algorithms that fail to account for the interference between cooperative and non-cooperative links. Novel dynamic spectrum management (DSM) techniques are proposed to manage such interference and the proposed techniques allow these limited cooperation scenarios to retain most of the cooperation benefits in next-generation cooperative systems while maintaining the performance of legacy non-cooperative systems. Chapter 2 focuses on the theoretical bounds in terms of achievable rate-regions, while Chapter 3 proposes distributed algorithms that can approximate the theoretical performance with low-complexity and practically implementable protocols in wire-line digital-subscriber-line (DSL) systems. The second part of the dissertation investigates the use of cross-layer protocols to balance QoS requirements of heterogeneous data, video, and other multimedia application traffic. Chapter 4 proposes cross-layer protocols for distributed scheduling that exploit the channel or noise cyclo-stationarity to enable higher throughputs for low-priority data traffic while meeting the QoS guarantees of high-priority video traffic, thereby promising to balance internet uplink speeds for both high-priority video traffic and low-priority data traffic in home networks. Chapter 5 proposes novel cross-layer pre-caching protocols to meet the increasing demands of IPTV traffic on wire-line broadband-access networks. IPTV viewers tend to watch at similar periods during the day (e.g. 6-9 PM or Friday nights), creating peak-bandwidth demands on interference-limited networks when there is insufficient physical-layer bandwidth to meet these demands. The proposed protocol estimates the impact of future peak-demand periods on interference-limited networks and pre-allocates bandwidth to deliver the forecasted videos and avoid the peak-demand periods.

"Future Internet" is a worldwide hot topic. The Internet has become a critical infrastructure for business development and social interactions. However, the immense growth of the Internet has resulted in additional stresses on its architecture, resulting in a network difficult to monitor, understand, and manage due to its huge scale in terms of connected devices and actors (end users, content providers, equipment vendors, etc). This book presents and discusses the ongoing initiatives and experimental facilities for the creation of new Future Internet Architectures using alternative approaches like Clean Slate and Incremental improvements: It considers several possible internet network use scenarios that include seamless mobility, ad hoc networks, sensor networks, internet of things and new paradigms like content and user centric networks.

The anatomy of the Internet: how it's structured, what makes it work, who controls it, and how to support internetworking capabilities in your organization If you work in any aspect of internetworking planning, design, development, or management, you need to have as complete a picture as possible of how the Internet is structured and what makes it work. Internet Architectures explains Internet components and the technical relationships between them, names the key players involved and the agreements currently in place between them, reveals proprietary architectures, and arms you with a wealth of practical information on: * Backbone technologies, including packet over SONET * Protocols and a description of ISP network architectures * Servers, routers, and software * Communications infrastructures * Access technology, including xDSL, ADSL, FITL, and frame relay * QoS and its support technologies, including ATM, RSVP, IPv6 * Policy, regulation, peering, and reciprocity arrangements * Multimedia and supporting technology * Internetworking security

This book constitutes the refereed proceedings of the 1996 International Zurich Seminar on Digital Communications, IZS'96, held in Zurich, Switzerland, in February 1996 and focusing on broadband communications. The 26 revised papers were selected from a total of some 70 submissions and give a snapshot of the state of the art in broadband communications. The book is divided into sections on broadband network architectures, designing for quality of service guarantees, protocol support for multimedia/multipoint services, traffic modeling and performance evaluation, fairness in resource allocation, applications, server functions in ATM, satellite and wireless networks, broadband access and switching, and acceptance and congestion control.

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.
