WHERE DID IT COME FROM?
-
Evolution from frame-relay
- Difference is that frame-relay uses variable-length packets (frames) and ATM uses fixed-length packets (cells).
- Evolution from circuit-switching
- Circuit-switching only allows fixed-data-rate circuits.
- ATM allows multiple virtual channels = more efficient.
