FPM-7620F fast path architecture

The two FPM-7620F NP7 network processors provide hardware acceleration by offloading data traffic from the FPM-7620F CPUs. The result is enhanced network performance provided by the NP7 processors plus the network processing load is removed from the CPU. The NP7processor can also handle some CPU intensive tasks, like IPsec VPN encryption/decryption. Because of the integrated switch fabric, all sessions are fast-pathed and accelerated.

Traffic from FPM-7620F front panel data interfaces is sent over the fabric channel backplane to the FIMs where NP7 processors use SLBC to distribute sessions to individual FPMs. The FPM-7620F can be processing traffic received from FIM data interfaces and from FPM data interfaces.
