More Information
ATM's use of fixed-size cells allows for predictable, efficient processing; the lack of inherent error control in Frame Relay is offset by its ability to support high-speed data transmission.
Tips
A common mistake when working with ATM is assuming variable packet sizes like in IP networks, but ATM consistently uses fixed 53-byte cells.
