Quality of Service (
QoS) is a set of technologies
that work on a network to guarantee its ability to dependably run high-priority
applications and traffic under limited network capacity. You can
configure QoS in Prisma Access to prioritize business-critical traffic
or traffic that requires low latency, such as VoIP or videoconferencing.
You can also reserve a minimum amount of bandwidth for business-critical
applications.
Prisma Access uses the same QoS profiles and
supports the same Differentiated Services Code Point (DSCP) markings
as next-generation Palo Alto Networks firewalls. However, the configuration
process is different than configuring QoS on next-generation firewalls,
in particular when your deployment allocates bandwidth by compute
location.
Prisma Access can either mark ingress traffic using
a security policy or it can honor DSCP markings set by your organization's
on-premises device.
Prisma Access for Clean Pipe also supports
QoS.

examples, and how to configure it.
