Chapter 7. IP, TCP, and UDP

This chapter covers the following topics:

• Layers and protocols

• IP

• TCP

• UDP

This chapter introduces the fundamental protocols used in intranets and, in particular, the server farms supporting web-based services. A number of other networking devices, such as firewalls, load balancers, and Secure Socket Layer (SSL) offloading devices, are also exposed to the operation of these fundamental protocols. These protocols include Transport Control Protocol (TCP) and User Datagram Protocol (UDP) at Layer 4 and Hypertext Transfer Protocol (HTTP) at Layer 5, which combined make a substantial percentage of traffic destined to the server farms in the Data Center.
