IP Overview

The term TCP/IP architecture refers to the networking architecture used in IP networks. It's much broader than just the two named protocols. IP or the Internet Protocol is the glue that keeps the Internet together. This section provides a brief overview of this architecture. For a more comprehensive overview, consult Comer's book on TCP/IP [COMER]. It is one of the standard references for learning about IP and associated protocols.

Like most networking architectures, the TCP/IP protocol suite is designed in layers (see Figure 2.1). Each layer provides a language that lets two machines talk to each other. Each layer uses the layer that is immediately below it, and is independent of the details of actual implementation of the lower ...
