Frame Relay is a technology that has been around
since 1990. It evolved out of the older X.25 packet technology and is the
packet part of ISDN and defined in I.122. Frame Relay is a simplified form of
Packet Switching similar in principle to X.25 in which synchronous frames of
data are routed to different destinations depending on header information.
The main differences between Frame Relay and X.25 are
that X.25 guarantees data integrity (error detection) and network managed flow
control at the cost of some network delays. Frame Relay switches packets much
faster end-to-end, but there is no guarantee of data integrity. Instead, it is
up to the end devices to check for and correct errors. .
