Chapter 2: Requirements Analysis: Concepts

In this chapter you will learn to develop service descriptions for networks and how to identify and/or derive network requirements from the system. You will learn that network requirements are coupled to services, and you will develop a requirements specification to map out requirements and help determine their dependencies. You will learn how to apply the concepts discussed in the last chapter to a variety of user, application, and device requirements, you will also learn to develop both a requirements specification and applications map.

2.1 Objectives

In this chapter we will expand the concept of requirements for a network. We will tune the general systems engineering process, introduced in the previous chapter, to the problem of networking. You will learn about different types of requirements from the user, application, device, and network components. You will learn about grouping requirements together and mapping the locations of applications and devices. The combination of all the requirements and locations will be expressed in two documents: a requirements specification and requirements map.
