Apply QoS for Youtube or Streaming Media

This document specifies how to apply QoS for streaming media websites.

Refer to the following topology. Ethernet 1/3 is the LAN interface and Ethernet 1/1 is a WAN interface.

1. Create a QoS profile.
   
   Create the QoS profile
   
   
2. Categorize the traffic to a specific class with the help of a QoS policy. 
   
   QoS policy NameQoS policy SourceQoS policy Destination
   You can add all the applications you want to limit:
   QoS policy Application
   
   And/Or you can set a URL filtering category:
   QoS policy URL Category
   And finally set the policy to match the class in the QoS profile you want it to match:
   QoS policy Class
   
   
3. This is important step. A QoS profile will be applied on egressing packets so the profile needs to be attached to the interface where the biggest data stream is going to exit the firewall. In this example internal clients are receiving streaming from the internet so the biggest data flow will go from the internet to the client and the QoS profile on the client side will be applied to limit the flow.  QoS Interface

Check  QoS statistics. Go to Network >QoS, then select statistics.
