Chapter 6 - Network layer protocols. Chapter summary: Network layer protocols are responsible for end-to-end communications across the network; IP is a connectionless protocol that encapsulates transport layer data into datagrams; IPX is a proprietary standard that performs routing, addressing, and protocol identification; NetBIOS Extended User Interface (NetBEUI) is used by small Windows networks for LAN networking; AppleTalk provides basic...

This chapter describes the delivery and forwarding of IP packets. Delivery refers to the way a packet is handled by the underlying networks under the control of the network layer. Concepts such as direct and indirect delivery are discussed. Forwarding refers to the way a packet is delivered to the next station. We discuss two trends in forwarding: forwarding based on destination address of the packet and forwarding based on the label attached...

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...

The chapter has several objectives: To discuss SNMP as a framework for managing devices in an internet using the TCP/IP protocol suite; to define a manager as a host that runs SNMP client and any agents as a router or host that runs a server program; discuss SMI and MIB, which are used by SNMP; to show how SMI names objects, defines the type of data, and encodes data;...

Mobile communication has received a lot of attention in the last decade. The interest in mobile communication on the Internet means that the IP protocol, originally designed for stationary devices, must be enhanced to allow the use of mobile computers, computers that move from one network to another.

Transferring files from one computer to another is one of the most common tasks expected from a networking or internetworking environment. As a matter of fact, the greatest volume of data exchange in the Internet today is due to file transfer. In this chapter, we discuss two protocols involved in transferring files: File Transfer Protocol (FTP) and Trivial File Transfer Protocol (TFTP).
