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 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 to the packet.

When the ARPANET was commissioned in 1969, no one anticipated that the Internet would explode out of the humble beginnings of this research project. Over the next decade, the number of hosts on the Internet grew exponentially, from 159,000 in October 1989 to over 72 million by the end of the millennium. As of January 2007, there were over 433 million hosts on the Internet.
