This book covers the planning, design and implementation of hybrid fiber-optic coaxial (HFC) broadband networks in schools, universities, hospitals, factories and offices, whether they are in a single building or multiple campuses. Within the next few yea

This book includes detailed coverage of digital cable systems -- most existing systems are analog. It shows how to control the return data coming from customers via the coax network. It discusses migrating from a broadcast-only network to one that can handle 2-way traffic.

Presents a thorough quantitative reasoning and analysis of HFC system technologies, including subcarrier multiplexed lightwave transmission systems and components, radio frequency modems for digital signals, and medium-access control protocols proposed by important standards bodies.

Much interest exists in broadband network services to deliver a variety of products to consumers, such as Internet access, telephony, interactive TV, and video on demand. Due to its cost efficiency, Hybrid Fiber Coaxial (HFC) technology is currently being considered by most Telcos and cable companies as the technology to deliver these products. The topological HFC network design problem as implemented by several major companies is a form of the capacitated tree-star network design problem. We propose a new formulation for this problem and present a heuristic based on hierarchical decomposition of the problem. The proposed solution methodology exploits an Adaptive Reasoning Technique (ART), embedded as a meta-heuristic over specialized heuristics for the subproblems. In this context, we demonstrate the dynamic use of an exact solution technique within ART. The generalizability of the proposed solution methodology is demonstrated by applying it to a second problem, the Traveling Salesman Problem (TSP). Computational results are presented for both the HFC network design problem and the TSP, indicating high-quality solutions expending a very modest computational effort. The proposed solution method is found to be effective, and is shown to be easily adaptable to new problems without much crafting, and as such, has a broad appeal to the general operations research community.

Broadband Cable Access Networks focuses on broadband distribution and systems architecture and concentrates on practical concepts that will allow the reader to do their own design, improvement, and troubleshooting work. The objective is to enhance the skill sets of a large population that designs and builds broadband cable plants, as well as those maintaining and troubleshooting it. A large cross-section of technical personnel who need to learn these skills design, maintain, and service HFC systems from signal creation through transmission to reception and processing at the customer end point. In addition, data/voice and video specialists need to master and reference the basics of HFC design and distribution before contending with the intricacies of their own unique services. This book serves as an essential reference to all cable engineers—those who specifically design and maintain the HFC distribution plant as well as those primarily concerned with data/voice technology as well as video technology. - Concentrates on practical concepts that will allow the user to do his own design, improvement, and trouble-shooting work. - Prepares cable engineers and technicians to work with assurance as they face the latest developments and future directions. - Concise and tightly focused, allowing readers to easily find answers to questions about an idea or concept they are developing in this area.

This dissertation contributes to a growing body of research concerning internally controlled peer-to-peer systems tailored to their underlying access network. It describes a set-top box based peer-to-peer service built on top of the hybrid fiber-optic and coaxial star-bus topology used by the U.S. cable industry. By efficiently using the broadcast-based coaxial cables at the edge of the network, the set-top boxes are able to share data with each other efficiently to enhance video-on-demand services. We show that these methods can reduce the traffic load on expensive fiber-optic networks and specialized video servers by limiting traffic to the cheaper coaxial lines.
