FortiOS Handbook V2, Chapter 14: Traffic Shaping

FortiGate units can implement Quality of Service (QoS) by applying bandwidth limits and prioritization. Using traffic shaping, you can adjust how your FortiGate unit allocates resources to different traffic types to improve the performance and stability of latency sensitive or bandwidth intensive network applications. This document discusses Quality of Service (QoS) and traffic shaping, describes FortiGate traffic shaping algorithms, and provides procedures and tips on how to configure traffic shaping on FortiGate units.
