What are the responsibilities of the transport layer of the TCP/IP protocol?
The transport layer handles the problem of directing information between processes, rather than just between machines.
For example, a single machine may be involved in many network transactions at the same time, including FTP
sessions, telnet sessions, and World Wide Web (HTTP
The transport layer ensures that traffic intended for the FTP service reaches the process responsible for that
service, separately from traffic intended for the HTTP and other services.
The two transport-layer protocols in TCP/IP networking are called the User Datagram
and the Transmission Control Protocol (TCP).
- File Transfer Protocol (FTP) : Protocol used to transfer data over a network.
- User Datagram Protocol: A connectionless datagram service in the Transport layer used by applications that typically transmit small quantities of data.
Hypertext Transfer Protocol (HTTP) : Hypertext Transport Protocol defines how messages are formatted and
transmitted over the Web and how Web browsers should respond to those messages.
