FRF.12
From Wikipedia, the free encyclopedia
The FRF.12 specification describes the method of fragmenting Frame Relay frames into smaller frames.

[edit] 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 disrupt a service guarantee given to another virtual circuit.
[edit] 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.
[edit] 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.
