ATM (Asynchronous Transfer Mode) is a network technology, which is based on transferring the data in cell or packets of a fixed size.
Can you tell me if the cell used with ATM, is small or large and why ?
Is there any difference between ATM and TCP/IP ? If yes, list out the difference.
ATM ( Asynchronous Transfer Mode) main function
ATM is a permanent shared networking technology, that offers very low latency and jitter at much higher bandwidths. The fixed length of an ATM cell is 53 bytes. It contains a header of 5 bytes and a payload of 48 bytes. Compared to other technologies such as Frame Relay that uses frames, ATM cells are smaller in size.
Differences between ATM and TCP/IP
The TCP/IP protocol suite is the internet working protocol used on the Internet, ATM technology is the most appropriate standard used by telecommunications and computer vendors, for high speed networks.
TCP/IP uses packets, ATM uses cells.
ATM uses cell switches, not bridges or routers.
