Chapter 24. TCP: Transmission Control Protocol
24.1. Introduction
The Transmission Control Protocol, or TCP, provides a connection-oriented, reliable, byte-stream service between the two end points of an application. This is completely different from UDP’s connectionless, unreliable, datagram service.
The implementation of UDP presented in Chapter 23 comprised 9 functions and about 800 lines of C code. The TCP implementation we’re about to describe comprises 28 functions and almost 4,500 lines of C code. Therefore we divide the presentation of TCP into multiple chapters.
