About the FortiGate-ASM-FB4
When installed in a compatible FortiGate unit’s AMC (Advanced Mezzanine Card)
slot, FortiGate-ASM-FB4 modules provide additional hardware accelerated
network processing for certain eligible traffic types passing through their SFP
(small form-factor pluggable) network interfaces. This additional processing
resource frees FortiGate units’ main processing resources for other tasks,
improving network performance.
FortiGate-ASM-FB4 modules can improve network throughput for:
• traffic with small packets, such as VoIP
• latency-sensitive traffic, such as streaming multimedia
• traffic with long session lifetimes, such as FTP
• IPSec VPN traffic
• active-active HA load-balanced traffic
• P2P traffic
Eligible traffic processing is offloaded to the FortiGate-ASM-FB4 module. This fast
path processing leverages the additional hardware acceleration resources
provided by the FortiGate-ASM-FB4 module.
Ineligible traffic processing is processed normally. Normal processing by the
FortiGate unit’s main processing resources (CPU, RAM, and FortiASIC content
processor) can include some FortiASIC hardware accelerated processing, but
does not utilize the additional hardware acceleration resources provided by the
FortiGate-ASM-FB4 module.
