A Palo Alto Networks firewall provides basic QoS, controlling
traffic leaving the firewall according to network or subnet, and
extends the power of QoS to also classify and shape traffic according
to application and user. The Palo Alto Networks firewall provides
this capability by integrating the features
App-ID and
User-ID with
the QoS configuration. App-ID and User-ID entries that exist to
identify specific applications and users in your network are available
in the QoS configuration so that you can easily specify applications
and users for which you want to manage and/or guarantee bandwidth.
