Chapter 7 Firewall : Firewall concepts : Quality of Service
  
Quality of Service
The Quality of Service (QoS) feature allows the management of the level of service and preference given to the various types and sources of traffic going through the firewall so that the traffic that is important to the services and functions connecting through the firewall gets the treatment required to ensure the level of quality that is required. QoS can be helpful for organizations that are trying to manage their voice and streaming multi-media traffic, which can rapidly consume bandwidth. Both voice and streaming multi-media are sensitive to latency. FortiGate units support QoS using traffic policing, traffic shaping, and queuing.
