Frame relay does not process the packets; it relays them from the switch's input port to the output port, hence the name.

Frame Relay is a fast WAN protocol that operates at the physical and data link layers of the OSI model. Works between DTE and DCE devices. Uses packet switching. DTE consists of terminals, PC’s, routers and bridges, all of which are customer owned end node devices. DCE devices such as packet switchers are owned by the service provider. Frame Relay uses Permanent Virtual Circuits. The connection is identified by a Data Link Connection Identifier.
Frame Relay offers a speed between 56 Kbps and 2078 Mbps. However, the default setting for a serial DCE interface is TI. Frame Relay uses a CRC, bad packets are discarded and the receiving station requests re-transmission of any missing frames.
