Asynchronous Transfer Mode (ATM)
Newer than X.25; also standardized
ATM in MAN/WAN similar to ATM technology discussed for BNs
Similar to X.25
- Provides packet switching service
Different than X.25: Operating characteristics
- Performs encapsulation (no translation) of packets
- Provides no error control (an unreliable protocol)
- Provides extensive QoS information
- Scaleable (easy to multiplex ATM circuits onto much faster ones)
