TCP/IP Explained concentrates on how each protocol works within the Internet Protocol Suite and discusses the addressing, delivery, transport and routing protocols. Many books on this subject concentrate on why protocols are designed in a particular way. This book concentrates on how they actually work. The approach is practical, and the reader can see how network changes affect overall operation. Ignored by many writers on the subject, but none the less important, are the Link Layer protocols that enable both interoperability between vendors and remote access to networks. This book describes these protocols in detail and includes the very latest enhancements. Equally, network managers must think about security when considering networks of this type. By providing useful examples of how such systems can be applied, this book discusses exactly what is needed to create a secure environment. TCP/IP Explained can be broadly split into four sections. The first section deals with the basics of the TCP/IP suite and how data is transported between two systems. The second section discusses routing principles and protocols. The third section deals with applications, and the fourth section discusses miscellaneous areas, such as common protocols used across wide area networks, securing networks, and the future of IP. 7 Covers all aspects of TCP/IP and includes internetworking in the wide are and remote access 7 Combines self-study with reference material
