QoS or Priority Policy Rules are contained within a QoS set. QoS policy rules determine
application priority within a network. They include attributes such as Network
Context, IP Prefix filters, Application ID, User/Group ID, Device ID, Priority
class, and DSCP for an application.
Network context—Network context segments network traffic
for the purpose of applying different QoS policy rules for the same
application. This gets the highest order of precedence.
Source prefix filter—Source based attributes get precedence
over destination based attributes. Source prefix filters are often
added as exceptions, so these get a higher precedence over applications.
Applications—These are destination based, hence lower in
the order of precedence.
Destination prefix filter—These are often added in context
of an application, so destination prefix filters get lower precedence
than applications.
Priority—Priority determines the relative priority of network
resources assigned to each application.
DSCP Values - When policy rules with marked DSCP bits are
applied to a site, the ION branch device will honor the bits in
the first packet on an unknown application flow, and queue the flow
in the specified priority class.
QoS policy rules
are added to the QoS policy sets.
