QoS is used to allocate bandwidth and prioritize applications to individuals and to groups of users.
On select models, you can define user groups by IP and subnet. Bandwidth controls and application priority can then be applied according to user groups.
Bandwidth reservation per user group under full load
Defines how much minimum bandwidth will be reserved to each user group when a WAN connection is in full load.
Per user group bandwidth control
Gives fine-grained control over download and upload rate limits to groups of users.
By Applications and Protocols
QoS recognizes certain application protocols, for example, in the Audio Video Streaming category, there is:
It is possible to pick entire categories such as “All Supported Streaming Applications”, or pick a certain Application within the category, such as HTML5 only.
Then adjust the priority for each user group:
For applications that do not belong to a particular category, it is possible to define a custom application, its protocol and ranges (i.e. TCP 2-22) or assign DSCP values.
