Establishing a connection
Terminating a connection
n Connection-oriented protocols establish a (logical) connection to the communication
partner before data transmission is started.
n And if necessary they terminate the connection after the data transfer was finished.
n Connection-oriented protocols are used for data transmission when reliable, guaran-
teed delivery is of particular importance.
n In general, many logical connections can exist on one physical line.
