transport layer (L4)

layer that provides transparent transfer of data between end users
NOTE: The transport layer constitutes layer 4 of the OSI model.

transport profile

set of services which are responsible for providing a virtually error-free, point-to-point connection so that host A can send data packets to host B and they will arrive uncorrupted
NOTE: Connection-oriented transport profiles may also ensure that the data packets arrive in the correct order.

turn-around time

period of time it takes a client or server to produce and transmit a response data packet, measured starting from the point at which the last byte of data is received from the other system to the point when the last response byte is transmitted
