Chapter 10. Architectural Elements and Examples

10.1. Introduction

Network architecture is the logical and physical interconnection of all elements between a signal's generation and its termination. Chapter 9 dealt with ways of measuring architecture-related parameters and the needs of various types of services. This chapter will first delineate each of the elements from which an architecture is constructed and then present some examples of high-level HFC distribution networks that have been proposed or built. Fiber-deep architectures will be covered in Chapter 11; the relationship between network architecture and service reliability and availability will be dealt with in Chapter 12.
