2: Direct Connections
The goal of this chapter is simultaneously to survey the available link-level technology and to explore these five fundamental issues. We will examine what it takes to make a wide variety of different physical media and link technologies useful as building blocks for the construction of robust, scalable networks.3: Internetworking
Once we understand the problems of switching and routing, we need some devices to perform those functions. This chapter concludes with some discussion of the ways switches and routers are implemented. While many packet switches and routers are quite similar to a general-purpose computer, there are many situations where more specialized designs are used.
