Abstract
Currently there are no policy classes defined for the PEP to convey
provisioned policy usage feedback to the PDP. The purpose of this
document is to define the policy usage feedback framework PIB that
specifies the policy classes common for COPS feedback reports. The
basic operation and objects for reporting usage information are
defined in [COPS]. A specific clientSI feedback object named REPORT
is defined in [COPS-PR]. A framework for approaching solicited and
periodic usage feedback is described in [COPS-FEED-FRWK]. This

document defines the policy classes for a feedback framework Policy
information base (PIB).

Internet Draft FEED-FRWK-PIB July 2001
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 also 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.
Generally, the selection criterion is an existing PRI such as an
instance of the frwkIPFilterTable. This PRC is useful for specifying
conditions on which to base usage - i.e. count the number of packets
received for this filter. The filter (source address, destination
address, etc.) in this case defines the conditions. In the case of
the feedback framework PIB, the frwkIPFilterTable is the only PRC
used to base selection on.
The usage policy defines what attributes are monitored and recorded
by the PEP. These policies have an ACCESS clause of Report.
Generally, the usage policies specify counts related to a specific
action such as a packet being dropped. The feedback framework PIB
defines one usage policy class, frwkFeedbackFilterStats. It counts
packets and bytes as well as records the timestamp when the last
packet was received. 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 PRC, in which case all statistics are gathered
using instances of that PRC. Alternatively, the PEP may support
multiple usage PRCs. The PDP then decides which PRC to associate with
a particular selection criterion.
A usage policy and selection policy are tightly associated with one
another. A third policy is used to associate, or link, the selection
and usage policies. The frwkFeedbackLinkTable performs this linking
of the selection and usage policies. The feedback report linkage
permits the same selection criteria instance to be re-used for
Rawlins et al. Expires January 2002 [Page 3]
Internet Draft FEED-FRWK-PIB July 2001
various usage policies. For example, the same IP Filter selection
criteria could be the basis of different usage policies such as
packet count, drop count, and remark count. The feedback type report
linkage references the selection criteria instance as well as defines
the policy class of the usage PRC. As noted above, the selection
criteria policy may be used for enforcement policies as well as usage
policies. This is the case with the frwkIPFilterTable.
----------------- ------------------ -----------------
| | | | | |
| Select Criteria | |Linkage Instance | |Usage Instance |
| | |-instance ID | |- instance ID |
| -instance ID |<--|-PRID of selection|--->|- PRID of Linkage|
| -conditions... | |-PRC of usage | |- counts... |
| | | | | |
----------------- ------------------ -----------------
Figure 1
Figure 1 illustrates the relationship between a selection criteria,
linkage and usage policies.
There is a one to one relationship between the report linkage policy
instance and the usage policy instance. The PDP is not aware of the
instance identifier of the usage policy when installing the selection
criteria and feedback report linkage policies. The usage policy is
instantiated on the PEP by the installation of a feedback report
linkage and the PEP designates the instance identifier. The usage
policy class always contains an attribute of type Prid which contains
the value of the associated feedback report linkage PRID [COPS-PR]
installed by the PDP. Note that the Prid type is a textual convention
for an object identifier that is the PRC of the table used for the
feedback report linkage and where the last sub-identifier is an
instance ID of the feedback report linkage.
2.2 Normal Operations
2.2.1 Connection Establishment and Initial Configuration Request
The Accounting Timer object in the Connection Accept message contains
the minimum number of seconds between reporting intervals as
described in [COPS] and [COPS-FEED-FRWK.] 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 the frwkPRCSupportTable entries[FR-PIB]. The
PEP also indicates whether it supports the frwkFeedbackLinkTable as
well.
Rawlins et al. Expires January 2002 [Page 4]
Internet Draft FEED-FRWK-PIB July 2001
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 and
does this with the frwkFeedbackLinkInterval attribute in the
frwkFeedbackLinkTable instance. The PEP monitors and records the
usage per the conditions defined by its associated selection criteria
policy. Periodically the PEP reports the usage with an feedback type
REPORT or provides a REPORT when solicited by the PDP. The PDP
solicits usage feedback with the frwkFeedbackResumeIndicator
attribute of the frwkFeedbackResumeTable.
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.
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 usages
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 Solicited Reports
The PDP may solicit policy usage feedback by issuing an unsolicited
Decision containing the frwkFeedbackResumeIndicator set to SOLICIT
USAGE NOW. 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.
2.2.4 Resuming and Suspending Periodic Feedback Reporting
The PDP may suspend usage monitoring and tracking at the PEP with the
frwkFeedbackResumeIndicator set to SUSPEND USAGE MONITORING AND
REPORTS. The PEP must stop tracking usage information and must not
issue any feedback reports. The PDP may only suspend feedback
reporting by setting the ResumeIndicator to SUSPEND REPORTS ONLY. 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
ResumeIndicator to RESUME USAGE AND REPORTING.
The PDP may suspend or resume for all usage instances or the PDP may
specify one or more instances that are to be suspended or resumed.
The ResumeList contains a tag identifier that references a list of
one or more frwkFeedbackSolList entries.
The PDP may halt usage monitoring, tracking and reporting of usage
policies by removing the associated Linkage entry.
Rawlins et al. Expires January 2002 [Page 5]
Internet Draft FEED-FRWK-PIB July 2001
2.2.5 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
feedback type report messages. The PDP does this deterministically.
It issues an unsolicited decision containing the
frwkFeedbackResumeIndicator set to resume reporting. 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.
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 Feedback Type Report Group and PRCs
It is useful to define reporting intervals, and suspend, resume, and
solicit characteristics as well as the common usage and selection
criteria polices. These policy classes are common to account type
reporting for various technologies and apply to ALL SUBJECT-
CATEGORIES. The policy classes belong to a new group, Feedback Type
Report Group. The policy classes in the Feedback Type Report Group
are:
1) Feedback Action Table
2) Feedback Action List Table
3) Feedback Linkage Table
4) Feedback Filter Statistics Usage Table
3.2.1 Feedback Action Table
The Feedback Action Table contains the attributes that specify
action that the PEP is to take regarding policy usage, monitoring
Rawlins et al. Expires January 2002 [Page 6]
Internet Draft FEED-FRWK-PIB July 2001
and tracking. The PDP may suspend usage monitoring and periodic
reporting, suspend periodic reporting only, resume usage and
periodic reporting or solicit immediate reporting. The action may
affect all feedback policies or be associated with one or more
policy instances.
The Feedback Action Indicator defines the action. The Feedback
Specific PRI indicates whether the action applies to all of the
usage policies or to a list. The Feedback List ID 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.
3.2.2 Feedback List Table
This table contains a list of PRIDs of the linkage table for which
the PDP wants feedback reports. The value is referenced by an
attribute in the Feedback Resume Table. There may be one or more
instances associated with a specific list identifier defined by the
Feedback Action List ID.
3.2.3 The Feedback Report Linkage Table
This table links the selection criteria instance with the usage
instance. It specifies the PRID of the selection criteria and the PRC
of the usage instance. 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 feedback type reports for the usage
instance. This interval is defined in units of the Accounting Timer
Rawlins et al. Expires January 2002 [Page 7]
Internet Draft FEED-FRWK-PIB July 2001
Interval specified in the client accept message. A value of 0 in this
attribute indicates that the usage policy must be solicited.
3.2.4 The Feedback Filter Statistics Usage Table
This table describes the packet counts, byte counts, last timestamp
when a packet was received and the PRID of the associated Feedback
Report Linkage instance. The count and timestamp information is
monitored and recorded by the PEP and supplied to the PDP with the
feedback type report message within the maximum interval specified.

5 Security Considerations
The feedback information is sensitive and requires that authorized
messaging occur between the PEP and the PDP. This protection can
be accomplished with IPSEC between the PEP and the PDP or using
the security mechanisms described in the base COPS protocol.
