  • This chapter is an introduction to the application layer. In the next eight chapters we introduce common client-server applications used in the Internet. In this chapter, we give a general picture of how a client-server program is designed and give some simple codes of their implementation. The area of network programming is a very vast and complicated one; it cannot be covered in one chapter. We need to give a bird’s-eye view of this discipline to make the contents of the next eight chapters easier to understand.

  • The primary duties of the transport layer, Layer 4 of the OSI model, are to transport and regulate the flow of information from the source to the destination, reliably and accurately. End-to-end control and reliability are provided by sliding windows, sequencing numbers, and acknowledgments To understand reliability and flow control, think of someone who studies a foreign language for one year and then they visit the country where that language is used.

  • As WLANs (Wireless Local Area Networks) become increasingly common, it's becoming vital to be able to test them for proper performance and to optimize their operation. This book, written by a member of the IEEE committee that develops WLAN standards, is the first book addressing that need. It covers test equipment and methods for the RF (wireless) and physical layers of WLAN, protocols, the application layer, and manufacturing testing.

  • Chapter 2 - Application layer. In this chapter we study the conceptual and implementation aspects of network applications. We begin by defining key application-layer concepts, including network services required by applications, clients and servers, processes, and transport-layer interfaces. We examine several network applications in detail, including the Web, e-mail, DNS, and peer-to-peer (P2P) file distribution.

  • Chapter 2 - Application layer. his chapter explores the different application programs, or services, available at the topmost layer, layer five, of the Internet model. In this chapter, we introduce the application layer and its relationships to the other layers. We discuss the client-server paradigm, the only one used today in the Internet. We also discuss addressing, a feature inseparable from the application layer.
