Frame Relay
Another standardized technology
Faster than X.25 but slower than ATM
Encapsulates packets
- Packets delivered unchanged through the network
Unreliable, like ATM
- Up to the end-points to control the errors
NO QoS support (under development)
Common CIR speeds:
- 56, 128, 256, 384 Kbps, 1.5, 2, and 45 Mbps
