Frame relay is a packet-switched WAN technology that provides cost savings over leased lines by allowing for higher circuit utilization and network availability. It connects user devices like PCs and network hosts to packet switches that make up the frame relay network. While it offers benefits like protocol independence and performance, frame relay is not suitable for real-time applications due to varying delays, cannot support data rates higher than 44.376 Mbps, and may be more expensive than internet services.

Cost savings Higher circuit utilization Higher network availability Extended technology life duration Protocol independence Performance
The flow control and error control is not available in frame relay. This should be taken care by upper layer protocols. Allows variable length frames and hence may create varying delays for different users. Due to varying delay, it is not suitable to send sensitive data like real time voice or video. Can operate at 44.376 Mbps and hence it is not suitable for protocols requiring higher data rates. More expensive compare to internet service.
