1.8 Summary

In this chapter we discussed the structure of TCP/IP, the protocol suite upon which the Internet is built. We have seen that TCP/IP is a hierarchy of four layers: Applications, Host-to-Host Transport, Internet, and Network Access. We have examined the function of each of these layers. In the next chapter we look at how the IP packet, the datagram, moves through a network when data is delivered between hosts.
