15.1. Introduction

Chapter 13 dealt with the establishment and termination of TCP connections, and Chapter 14 examined how TCP ensures reliable delivery using retransmissions of data that has been lost. We now examine the dynamics of TCP data transfers, focusing initially on interactive connections and then introducing flow control and associated window management procedures that are used in conjunction with congestion control (see Chapter 16) for bulk data transfers.

An “interactive” TCP connection is one in which user input such as keystrokes, short messages, or joystick/mouse movements need to be delivered between a client and a server. If small segments are used to carry such user input, the protocol ...
