QoS Support Overview

Below config snapshot shows how to configure application filtering in the network slice. Each application filter in the network slice can have action either permit or deny Also each application has QoS rates. QoS rates are part of device groups are per UE limit.

Note

TBD : add REST api documentation to change slice QoS rates. TBD : How to update slice QoS configuration in P4-UPF
