Abstract
This document describes a Policy Information Base (PIB) to control
policy usage collection and reporting in a device.
The provisioning classes specified here allow a Policy Decision
Point (PDP) to select which policy objects should collect usage
information, what information should be collected and when it
should be reported.
This PIB requires the presence of other PIBs (defined elsewhere)
that provide the policy objects that usage information is collected
from.

Internet Draft Feedback-FR-PIB June 2002
1 Introduction
The Framework of COPS-PR Usage Feedback describes the overall
approach to policy usage monitoring and reporting. This document
defines the specific Policy Information Base (PIB) framework for
policy usage feedback. The policy classes for monitoring and
reporting policy usage feedback as well as policy classes for
controlling reporting intervals, suspension, resumption and
solicitation are defined.
2 General Concepts
2.1 Selection, Usage and Linkage Policies
There are three basic types of policy used to define what the PEP is
to monitor, record and report. These are the selection criteria
policy, the usage policy and the feedback report linkage policy.
The selection criteria policy is installed by the PDP. It defines the
conditions used by the PEP to monitor and record a usage policy. The
selection criteria policy may only be used for defining usage
feedback selection criteria. However, the more general case is that a
policy that already exists for policy enforcement may also be used
for specifying feedback usage selection criteria. An example of this
is the frwkRoleCombo instance, which may be used in defining QoS
enforcement policies but may also be used to specify conditions on
which to base usage - i.e. count the number of packets meeting the
criterion of an interface capability set name and role combination.
The usage policy defines what attributes are recorded by the PEP.
These policies have an ACCESS clause of 'report-only'. Generally, the
usage policies specify counts related to a specific action such as a
packet being dropped. The feedback framework PIB defines two usage
policy classes, frwkFeedbackTraffic and frwkFeedbackIfTraffic. Usage
PRCs may be generic, collecting basic statistics, or they may be
specific to a particular usage. The PDP decides which PRC(s) best
suit(s) its requirements. The PEP may support only one usage feedback
PRC, in which case all statistics are gathered using instances of
that PRC. Alternatively, the PEP may support multiple usage feedback
PRCs. The PDP then decides which PRC to associate with a particular
selection criterion.
A usage feedback policy and selection policy are tightly associated
with one another. A third policy, the frwkFeedbackLinkTable, is used
to associate, or provide a linkage for the selection and usage
policies. The frwkFeedbackLinkTable also specifies when to report the
usage feedback. The frwkFeedbackLinkTable entry permits the same
selection criteria instance to be re-used for various usage feedback
policies. The frwkFeedbackLinkTable contains the value of the
selection criteria instance as well as the value of the usage
feedback PRC.

Figure 1
Figure 1 illustrates the relationship between the selection criteria,
linkage and usage policies.
The PDP is not aware of the instance identifier of the usage feedback
policy when installing the selection criteria and feedback linkage
policies. The usage feedback policy is instantiated on the PEP by the
installation of a feedback report linkage and the PEP designates the
instance identifier. The usage feedback policy class always contains
an attribute of type ReferenceId that contains the instance value of
the associated frwkFeedbackLinkTable instance installed by the PDP.
An example of this is the attribute frwkFeedbackTrafficLinkRef
2.2 Normal Operations
2.2.1 Connection Establishment and Initial Configuration Request
The Accounting Timer object in the COPS Connection Accept message
contains the minimum number of seconds between reporting intervals as
described in [COPS] and [FEEDBACKfWK]. This is used as the basic unit
of measurement in defining intervals for specific usage policies with
the frwkFeedbackLinkInterval attribute.
The PEP notifies the PDP of the selection criteria policy classes and
usage policy classes it supports during the initial request for
configuration data using frwkPRCSupport instances [FR-PIB]. The PEP
also indicates whether it supports the frwkFeedbackLinkTable as well.
The PDP responds to the initial request for configuration with a
DECISION that installs policies. The PDP may also specify maximum
reporting intervals associated with each of the usage policies. This
is done with the frwkFeedbackLinkInterval attribute in the
frwkFeedbackLink class. It may also specify reporting thresholds by
including an instance of a threshold class (e.g.
frwkFeedbackTrafficThreshold) in the decision. The PEP monitors and
records the usage per the conditions defined by its associated
selection criteria policy. Periodically the PEP reports the usage
with a REPORT message or provides a REPORT when solicited by the PDP.
The PDP solicits usage feedback with the frwkFeedbackActionIndicator
attribute of the frwkFeedbackAction class.
Rawlins et al. Expires December 2002 [Page 4]
Internet Draft Feedback-FR-PIB June 2002
2.2.2 Unsolicited Reports - Periodic Reporting
Reporting may be periodic in nature and unsolicited. The intervals
at which the unsolicited reports are provided by the PEP are defined
in the specific Linkage policies. The defined intervals are based on
the number of seconds specified by the PDP in the ACCT Timer value.
The PDP may specify that the associated usage instance be included
in a periodic unsolicited report only if the threshold is reached
and/or if the usage value has changed from the previous reporting
interval.
There are cases when the PEP must supply unsolicited feedback
reports that may not fall on an interval boundary. The PEP MUST
provide an unsolicited REPORT containing all defined usage instances
just prior to the PEP issuing a Delete Request State and just prior
to the PEP de-activating a PIB instance context.
2.2.3 Unsolicited Reports - Reporting Conditions
Periodic unsolicited reports for individual usage feedback instances
can be suppressed by specifying additional conditions in the
frwkFeedbackLink instances. Supported conditions are:
ChangeOnly
If this flag is set in the frwkFeedbackLinkFlags attribute, the
associated usage instance is only included in a periodic
unsolicited report if its value changed since the last
unsolicited report.
Threshold
If this flag is set in the frwkFeedbackLinkFlags attribute, the
associated usage instance is only included in a periodic
unsolicited report, if the threshold condition referenced in
the frwkLinkThreshold field evaluates successfully for the
associated usage instance.
Both conditions can be combined in one frwkFeedbackLinkUsage object.
In this case both conditions need to succeed for the usage instance
to be reported.
Unsolicited reports triggered by a Delete Request State or the
deactivation of a PIB instance are not subject to these conditions -
all usage objects must be included in these cases.
2.2.4 Solicited Reports
The PDP may solicit policy usage feedback by issuing an unsolicited
Decision containing the frwkFeedbackActionIndicator set to
'solicitReport'. The PEP is to provide a solicited REPORT feedback
containing usage feedback. The PEP shall continue to provide
periodic feedback as well at the specified intervals established at
client connection acceptance.
Rawlins et al. Expires December 2002 [Page 5]
Internet Draft Feedback-FR-PIB June 2002
The reporting conditions (ChangeOnly and Threshold) do not affect
solicited reports - all requested usage instances must be included.
2.2.5 Resuming and Suspending Periodic Feedback Reporting
The PDP may suspend usage monitoring and tracking at the PEP with the
frwkFeedbackActionIndicator set to 'suspendMonitoringAndReports'. The
PEP must stop tracking usage information and must not issue any
feedback reports. The PDP may only suspend feedback reporting by
setting the ActionIndicator to 'suspendReports'. The PEP must cease
sending unsolicited reports but is to continue monitoring and
tracking usage. The PDP may resume the sending of feedback reports
and may resume usage monitoring by setting the ActionIndicator to
'resume'.
The PDP may suspend or resume all usage instances or the PDP may
specify one or more instances that are to be suspended or resumed.
The frwkFeedbackActionList attribute contains a tag identifier that
references a list of one or more frwkFeedbackActionList instances.
The PDP may halt usage monitoring, tracking and reporting of usage
policies by removing the associated Linkage entry.
2.2.6 Failover
In the event the connection is lost between the PEP and PDP, the PEP
continues to track usage information as long as it continues to
operate with the installed policy. When the locally installed policy
at the PEP expires, the usage policy data also expires.
Upon successful reconnection where the PEP is still caching policy,
the PDP indicates to the PEP that the PEP may resume sending of the
COPS accounting type report messages. The PDP does this by issuing an
unsolicited decision containing the frwkFeedbackResumeIndicator set
to 'resume'. The PEP should resume reporting at the next appropriate
feedback interval established upon the acceptance of the re-
connection. The PDP is aware of the request state Handle(s) and the
supported PRCs either through the state synchronization mechanism or
because the PDP considers itself synchronized with the PEP upon
reconnection.
2.3 Usage Policy and Under-specified Selection Criteria
Some of the usage 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
assignments 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
Rawlins et al. Expires December 2002 [Page 6]
Internet Draft Feedback-FR-PIB June 2002
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 assignments.
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:
A frwkRoleCombo instance may be used as a selection criteria,
identifying a set of interfaces through their the role
combination and capability set. If it is desired to get per-
interface traffic statistics, the usage PRC has to include an
additional attribute to qualify the specific interface.
This could be achieved by linking the frwkFeedbackIfTraffic class
with a frwkRoleCombo instance in a frwkFeedbackLink instance.
Multiple frwkFeedbackIfTraffic instances will be created by the
PEP, one for each interface selected by the frwkRoleCombo
instance. The frwkFeedbackIfTraffic class contains the
frwkFeedbackIfTrafficIfIndex attribute that allows the PDP to
identify each interface's individual counters when the PEP
reports the frwkFeedbackIfTraffic instances.
If traffic usage collection is only desired for an individual
interface, a selection criteria should be used that qualifies the
interface completely, for example a frwkIfRoleCombo instance.
In this case it can be linked to the usage class that has no
additional qualifying attributes, frwkFeedbackTraffic.
3 Summary of the Feedback Framework Policy Information Base
3.1 SPPI ACCESS clause report-only
The selection criteria and linkage policy classes follow the
definitions specified by [SPPI]. This structure specifies well-
defined policy classes and their instances residing in a common,
virtual repository [FR-PIB]. The additional PIB-ACCESS clause
attribute of "report-only" denotes the usage policy class reported by
the PEP.
3.2 Usage32 and Usage64 textual conventions
Rawlins et al. Expires December 2002 [Page 7]
Internet Draft Feedback-FR-PIB June 2002
The SPPI does not support the Counter32/64 textual conventions (TC)
of SNMP - for feedback collection two similar textual conventions
have been defined in this PIB: Usage32 and Usage64.
In addition to the differential functionality of 'Counter', where
only the difference between two samples generally carries
information, a single value of a 'Usage' attribute usually provides
absolute information, since
- its initial value is known (0)
- no wrap-around events should occur
- the time or event when the initial value was set should be
available directly or indirectly from other objects.
When 'Usage' attributes are defined in a PRC, events that could
cause a reset of the attribute to it's initial value should be
defined in the description as well as the mechanism that allows the
PDP to detect the time of the last reset.
No usual COPS activity however should cause the reset of a Usage
attribute. In the case of a suspension of monitoring activity
(frwkFeedbackActionIndicator set to 'suspendMonitoringAndReports'),
'Usage' attributes should keep their values and continue counting
after monitoring is resumed.
3.3 Feedback Groups and PRCs
These policy classes defined in this PIB are common to account type
reporting for various technologies and apply to ALL SUBJECT-
CATEGORIES. The policy classes are divided into three new groups,
namely, The Feedback Report Group, The Feedback Usage Group and The
Feedback Selection Group.
The policy classes in the Feedback Report Group are:
- Feedback Action
- Feedback Action List
- Feedback Selection Usage Combination Capability
- Feedback Linkage
- Feedback Traffic Statistics Threshold
The policy classes in the Feedback Usage Group are:
- Feedback Traffic
- Feedback Interface Traffic
The policy class in the Feedback Selection Group is:
- Feedback RoleCombo Filter Selection
3.3.1 Feedback Action
The Feedback Action class contains the attributes that specify
action that the PEP is to take regarding policy usage, monitoring
and tracking. The PDP may suspend usage monitoring and periodic
reporting, suspend periodic reporting only, resume usage and
Rawlins et al. Expires December 2002 [Page 8]
Internet Draft Feedback-FR-PIB June 2002
periodic reporting or solicit immediate reporting. The action may
affect all feedback policies or be associated with one or more
frwkFeedbackLink instances.
The frwkFeedbackActionIndicator attribute defines the action. The
frwkFeedbackActionPri attribute indicates whether the action applies
to all of the usage policies or to a list. The
frwkFeedbackActionList attribute is the identifier of the list of
Linkage policy instances to which the action is to be applied.
The PDP can solicit the PEP for immediate usage feedback. The PEP
shall respond with a solicited report containing the usage feedback.
The PDP can direct the resumption of usage monitoring and reporting
per the defined intervals. For example, the PEP may have re-
connected to a PDP and has cached usage policies. The PDP indicates
to the PEP to resume usage tracking and monitoring and to send all
the cached usage policy. The PEP shall respond at the next
appropriate interval with an unsolicited report containing the usage
feedback.
The PDP can suspend the monitoring of usage policy. The PEP
maintains the current usage that has been monitored but discontinues
any further monitoring until the PDP directs the PEP to resume
monitoring in a subsequent Decision.
The PDP can also suspend just the reporting of usage, but not
interrupt the monitoring and tracking of usage. The PEP shall
discontinue sending Report messages with usage feedback until the
PDP directs the PEP to resume. The PEP then begins reporting the
usage feedback at the next interval.
3.3.2 Feedback Action List
This class defines sets of linkage instances that can be referred to
from the frwkFeedbackActionList attribute.
3.3.3 Feedback Linkage Capability
This class defines the valid selection criteria PRC, usage PRC and
threshold PRC combinations supported by the PEP.
3.3.4 Feedback Linkage
This class links the selection criteria instance with the usage
class. This table permits the reuse of a selection criteria instance
for multiple usage policies.
The linkage table also permits the definition of a maximum reporting
interval to use when issuing the COPS accounting type reports for the
Rawlins et al. Expires December 2002 [Page 9]
Internet Draft Feedback-FR-PIB June 2002
usage instance. A value of 0 in this attribute indicates that the
usage policy must be solicited.
3.3.5 Feedback Traffic Statistics Threshold
This class is used to provide threshold values for the attributes
described in the traffic usage classes below.
3.3.6 Feedback Traffic
This class includes the packet counts, byte counts and a reference to
the associated Linkage instance.
3.3.7 Feedback Interface Traffic
This class is similar to the previous Feedback Traffic class, except
that it includes an additional reference to an interface index. This
class should be used with a selection criteria instance that matches
an element that is assigned to multiple interfaces. The interface
field can be used to associate the instances of this table with the
specific element's assignment.
3.3.8 Feedback RoleCombo Filter Selection
This class is used as selection criteria based on role combination,
capability set and a filter instance.

5 Security Considerations
This PIB defines structured information that may be sensitive when
transported by the COPS protocol [COPS-PR].
This PIB does not contain classes that directly contain security
relevant information like passwords or monetary amounts, however
unauthorized access or changes to information defined in this PIB
could compromise network operations or reveal sensitive business or
personal information.
Specifically for the classes:
frwkFeedbackLinkCaps
This class has the ACCESS clause 'notify'. Access to this
information reveals feedback collection capabilities of the COPS
client and malicious changes could affect feedback operation by
misleading the server to generate corrupt feedback configuration.
frwkFeedbackLinkTable, frwkFeedbackAction, frwkFeedbackActionList,
frwkFeedbackTrafficThres, frwkFeedbackRoleFilterSel
These classes have the ACCESS clause 'install' and allow the COPS
server to control feedback collection and reporting on the
client. Access to this information exposes the client's
Rawlins et al. Expires December 2002 [Page 28]
Internet Draft Feedback-FR-PIB June 2002
configuration, malicious changes could disrupt network or
business operations and raise privacy issues.
frwkFeedbackTraffic, frwkFeedbackIfTraffic
These classed have the ACCESS clause 'report-only' and contain
the usage information delivered from the COPS client to the
server. Unauthorized access to this information may reveal
detailed information on the network and its users. Malicious
changes may affect network and business operations.
[COPS] and [COPS-PR] define mechanisms to secure the COPS protocol
communication and implementations of COPS servers or clients
supporting this PIB MUST follow the security guidelines specified
there.
6 IANA Considerations
This document describes the frwkFeedbackPib Policy Information Base
(PIB) module for standardization under the "pib" branch registered
with IANA. An IANA assigned PIB number is requested for this PIB
under the "pib" branch.
This PIB uses "all" in the SUBJECT-CATEGORY clause, so it applies to
all COPS client types. No new COPS client type is requested for this
PIB.
