Abstract

  This document describes a portion of the 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 from which usage information is collected.

1.  Introduction

  The Framework of Common Open Policy Service with Policy Provisioning
  (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.

  The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",

  document are to be interpreted as described in [RFC2119].

2.  General Concepts

2.1.  Selection, Usage and Linkage Policies

  There are three basic types of policies 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, a more general case is a
  policy that already exists for policy enforcement that 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



Rawlins, et al.              Informational                      [Page 4]

RFC 3571                 Framework Feedback PIB              August 2003


  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.

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.





Rawlins, et al.              Informational                      [Page 5]

RFC 3571                 Framework Feedback PIB              August 2003


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 at the specified intervals established at client
  connection acceptance.

  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 that 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





Rawlins, et al.              Informational                      [Page 6]

RFC 3571                 Framework Feedback PIB              August 2003


  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
  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 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.




Rawlins, et al.              Informational                      [Page 7]

RFC 3571                 Framework Feedback PIB              August 2003


     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

  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 its 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.

RFC 3571                 Framework Feedback PIB              August 2003


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 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



Rawlins, et al.              Informational                      [Page 9]

RFC 3571                 Framework Feedback PIB              August 2003


  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
  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.






Rawlins, et al.              Informational                     [Page 10]

RFC 3571                 Framework Feedback PIB              August 2003


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.

  Usage32 ::= TEXTUAL-CONVENTION

RFC 3571                 Framework Feedback PIB              August 2003


       DESCRIPTION
               "The Usage32 type represents a non-negative integer
               which monotonically increases.
               Usage32 initial value is 0 and the object-type using
               Usage32 needs to specify when it is initialized.

               The Usage32 type is intended to reflect the absolute
               number of counted events, so that even a new PDP
               after a COPS reconnect can use the value directly.

               If there is the possibility that the maximum Usage32
               value of 2^32-1 is exceeded during the lifetime
               of the Usage32 object, the larger Usage64 type
               should be used.

               If conditions other than the reset of the COPS
               subsystem exist that disrupt the monotonic
               characteristics of Usage32, these conditions and a
               method how to detect their presence should be
               specified in the description of the object-type using
               Usage32 or its enclosing object-types (e.g. the
               Entry or Table object-type of the Usage32
               object-type).

               Whenever the monotonic increase of Usage32 is violated,
               it should be reset to 0 and the fact that this occurred
               should be indicated through an appropriate mechanism,
               for example a corresponding object of type TimeStamp
               or TimeAndDate."

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 configuration;
     malicious changes could disrupt network or business operations and
     raise privacy issues.

  frwkFeedbackTraffic, frwkFeedbackIfTraffic

     These classes 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.





Rawlins, et al.              Informational                     [Page 31]

RFC 3571                 Framework Feedback PIB              August 2003


  [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 registration under the "pib" branch registered with
  IANA.  The IANA has assigned PIB number 5.

  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.

  The authors would like to thank Dave Durham, Ravi Sahita, and Russell
  Fenger of Intel and John K. Gallant of WorldCom for their
  contribution to this document.
