How Does LFI Work?
Figure 8.6 shows the basic process of LFI. LFI effectively chops up large datagrams
into smaller fragments (F) so they can be interleaved with real-time packets (R).
These resulting smaller packets are then mixed in with other packets by whatever
queuing mechanism has been configured (WFQ, LLQ, and so forth).When the
packets arrive at the other end, they are reassembled into their original forms.
