The TCP/IP Suite of Protocols

Understanding
This chapter introduces TCP/IP and provides an overview of the TCP/IP suite
of protocols.
The following are discussed here:
"The TCP/IP Suite of Protocols" on page 11
"Overview of TCP/IP Protocol Usage" on page 13
"Transport Layer Protocols" on page 15
"Internet Protocol" on page 18
"Assigning IP Network Addresses" on page 21
"Physical and IP Addresses" on page 26
"Creating Subnets" on page 28
"Routing" on page 35
"Error and Control Messages" on page 37
"Router Discovery Protocol" on page 37
The protocols in the TCP/IP suite roughly correspond to a network
communications model defined by the International Organization for
Standardization (ISO). This model is called the Open Systems Interconnection
(OSI) reference model. The OSI model describes an ideal computer network
system in which communication on the network occurs between processes at
discrete and identifiable layers. Each layer on a given host provides services
to the layers above it and receives services from the layers below it. Figure 1
