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...

In this chapter we discuss our first client/server application program, Dynamic Host Configuration Protocol (DHCP). This application is discussed first because it is the first client/server application program that is used after a host is booted. In other words, it serves as a bootstrap when a host is booted and supposed to be connected to the Internet, but the host does not know its IP address.

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...
