FIM-7904E fast path architecture
The FIM-7904E includes an integrated switch fabric (ISF) that connects the front panel interfaces to the DP2 session-aware load balancers and to the chassis backplanes. The ISF also allows the DP2 processors to distribute sessions among all NP6 processors on the FortiGate Processor Modules (FPM) in the FortiGate-7000E chassis.
