what is the name for the protocol data unit (pdu) of the data link layer?
transmission control protocol
bullet::::- the link layer pdu is the frame.









































on tcp/ip over ethernet, the data on the physical layer is carried in ethernet frames.









































section::::examples.:atm.









































atm's corresponding data link layer pdu is called a "cell".









































section::::examples.:media access control protocol data unit.









































a media access control protocol data unit (mpdu) is a message that is exchanged between media access control (mac) entities in a communication system based on the layered osi model.
protocol data unit
for example, the transmission control protocol (tcp) implements a connection-oriented transfer mode, and the pdu of this protocol is called a "segment", while the user datagram protocol (udp) uses datagrams as protocol data unit for connection-less transfer. a layer lower in the internet protocol suite, at the internet layer, the pdu is called a packet, irrespective of its payload type.









































section::::packet-switched data networks.









































in the context of packet switching data networks, a protocol data unit (pdu) is best understood in relation to a service data unit (sdu).
