As its name implies, the TCP/IP
transport layer does the work of transporting data between
applications on source and destination devices. A thorough
understanding of the operation of the transport layer is essential
to understanding modern data networking. This module will describe
the functions and services of this critical layer of the TCP/IP
network model.
Many of the network applications
that are found at the TCP/IP application layer are familiar to
even casual network users. HTTP, FTP and SMTP, for example, are
acronyms that are commonly seen by users of Web browsers and
e-mail clients. This module also describes the function of these and
other applications from the TCP/IP networking model.
Students completing this module should be able to:
- Describe the functions of the
TCP/IP transport layer.
- Describe flow control.
- Describe the processes of
establishing a connection between peer systems.
- Describe windowing.
- Describe acknowledgment.
- Identify and describe transport
layer protocols.
- Describe TCP and UDP header
formats.
- Describe TCP and UDP port
numbers.
- List the major protocols of the
TCP/IP application layer.
- Provide a brief description of
the features and operation of well-known TCP/IP applications.
