1. Frame relay was designed to support the Broadband Integrated Services Digital Network (B-ISDN).
2. Frame relay is a packet switching network service, but frame relay was designed around never, faster fiber-optic networks.
- 3. Frame relay assumes a more reliable network. The enables frame relay to eliminate much of the X.25 overhead required to provide reliable service on less reliable networks.
4. Frame relay typically is implemented as a public data network and, therefore, is regarded as a WAN protocol.
5. Frame relay provides permanent virtual circuits, which supply permanent virtual pathways for WAN connections. Frame relay services typically are implemented at line speeds 56Kbps up to 1.544Mbps (T1).
