Background

When multiplexing packet data from different virtual circuits or flows, Quality of Service concerns often arise. This is because a frame from one virtual circuit may occupy the line for a long enough period of time to disrupts a service guarantee given to another virtual circuit.

Fragmentation

Fragmentation is a well known method for addressing this. An incoming long packet is broken up into a sequence of shorter packets and enough information is added to reassemble that long frame at the far end.

FRF.12

FRF.12 is a specification from the Frame Relay Forum which specifies how to perform fragmentation on frame relay traffic in several different scenarios.
