Chapter 8 Hardware Acceleration : FortiGate NP6 architectures
  
FortiGate NP6 architectures
Many FortiGate models can offload some types of network traffic processing from main processing resources to specialized network processors. If your network has a significant volume of traffic that is suitable for offloading, this hardware acceleration can significantly improve your network throughput.
This chapter shows the fastpath architecture for the following FortiGate units:
FortiGate-1500D fast path architecture
FortiGate-3700D fast path architecture
