2.3 Detail Policy Usage Feedback Reporting
Some of the policy objects created in the PEP with COPS-PR can be
used by the PEP multiple times - they effectively act as templates
for the objects created by the PEP. COPS-PR only has the identity
(OID) of the object that is shared between all the assignment the
PEP created, however it is desirable to collect usage information
for each of the derived objects individually.
This capability is achieved in the feedback framework PIB by
distributing additional information to qualify a specific assignment
of an object between the selection criteria PRC and the feedback
usage PRC.
A selection criteria PRC that refers to a shared object but contains
no qualifying information selects all of the object's assignment.
Such a selection criteria PRC should be combined with a feedback
usage PRC that includes all the necessary information to identify a
specific assignment - a single selection criteria policy can then
result in the generation of many feedback usage objects, one for
each derived object.
If the selection criteria PRC contains all the required qualifying
attributes for a specific assignment, it is combined with a feedback
usage PRC that only contains the desired metrics but no additional
attributes.
Example:
As part of a data path, an IPFilter object can be assigned to
many combinations of interface and direction.
To refer to a specific assignment of an IPFilter for feedback
purposes, the reference to the IPFilter instance has to be
qualified with the interface and direction attributes.
Feedback from the filter on a specific interface:
As the selection criteria policy a
frwkFeedbackDPESelectionEntry is used which contains the
qualifying attributes:
frwkFeedbackDPESelectionDataPathElement Prid
frwkFeedbackDPESelectionInterface Prid
frwkFeedbackDPESelectionIfDirection IfDirection
In this case this policy would be combined in a
frwkLinkageEntry with the FrwkFeedbackTrafficUsage PRC. This
combination will result in only one
FrwkFeedbackTrafficUsageEntry to be created which only contains
the traffic counters.
Feedback from all interfaces a filter is assigned to:
By combining a frwkFeedbackDPESelectionQueryEntry as selection
criteria with the FrwkFeedbackIfTrafficUsage PRC, all the
assignments are selected and multiple
FrwkFeedbackIfTrafficUsageEntries get created. Each entry not
only carries the desired traffic counters but also the
qualifying attributes to associate it with the assignment:
frwkFeedbackIfTrafficUsageInterface Prid,
frwkFeedbackIfTrafficUsageIfDirection IfDirection
