FortiController-5913C session-aware load balancing (SALB)
This section provides a brief introduction to FortiController-5913C session-aware load
balancing (SALB). For more information, including example configurations see the
FortiController Session-Aware Load Balancing Guide
on the Fortinet documentation
website (
The FortiController-5913C uses 2 on-board FortiASIC DP processors to perform high-
performance session-aware load balancing (SALB). A single FortiController-5913C can
distribute millions of concurrent sessions to up to 12 workers and start millions of new
sessions a second. If a worker fails, sessions are re-distributed to the remaining workers.
Additional FortiController-5913Cs in the same chassis can be added for redundancy or to
increase the number of network interfaces. You can also add a second chassis for
chassis redundancy.

workers see these as fctrl1/1,
fctrl1/2, fctrl2/1, and fctrl2/2.
