Chapter Two. Internetworking Fundamentals


The term Internet, as explained in the previous chapter, refers to a collection of networks that are interconnected . The Internet Protocol makes it possible to build such internetworks. The interesting aspect of IP is that it makes it possible to build networks that can scale on a global basis without relevance to underlying network types of physical media or limitations. In order to understand some of the basic fundamentals of internetworking and IP, we need to take a look at various protocols at various layers in the stack. For the purpose of comparison, the functions that make internetworking possible are compared against the standard seven-layer Open Systems Interconnection (OSI) stack. In addition to understanding IP, Internet Control Message Protocol (ICMP), and ARP, which are network-layer protocols, this chapter looks at transport-layer and application-layer protocols.

Building blocks of the Internet, such as addressing, routing, and naming as well as various protocols at the network, transport, and application layers are described in this chapter. Readers who are already familiar with the Internetworking concepts can skip this chapter and move on to the next .
