FIM-7921F fast path architecture

The FIM-7921F includes an integrated switch fabric (ISF) that connects the front panel interfaces and the chassis fabric backplane to the NP7 processors. The NP7 processors receive sessions from the FIM front panel data interfaces and the FPM front panel data interfaces over the fabric backplane. The NP7 processors use SLBC to distribute sessions to FPMs over the fabric backplane.

The FIM-7921F also includes the following backplane communication channels:

  • Ten 400Gbps fabric backplane channel to distribute traffic to the FPMs.
  • Ten 50Gbps base backplane channel for base backplane communication with the FPMs.
  • One 1Tbps fabric backplane channel for fabric backplane communication with the other FIM.
  • One 50Gbps base backplane channel for base backplane communication with the other FIM.
