2. Introduction

   [SPPI] describes a structure for specifying policy information that
   can then be transmitted to a network device for the purpose of
   configuring policy at that device.  The model underlying this
   structure is one of well-defined provisioning classes and instances
   of these classes residing in a virtual information store called the
   Policy Information Base (PIB).

   One way to provision policy is by means of the COPS protocol [COPS]
   with the extensions for provisioning [COPS-PR].  This protocol
   supports multiple clients, each of which may provision policy for a
   specific policy domain such as QoS, virtual private networks, or
   security.

   As described in [COPS-PR], each client supports a non-overlapping
   and independent set of PIB modules.  However, some provisioning
   classes are common to all subject-categories (client-types) and need
   to be present in each.  This document presents a set of PRCs that
   are common to all clients that provision policy using COPS for
   Provisioning.


3. General PIB Concepts

3.1. Roles

   The policy to apply to an interface may depend on many factors such
   as immutable characteristics of the interface (e.g., ethernet or
   frame relay), the status of the interface (e.g., half or full
   duplex), or user configuration (e.g., branch office or headquarters
   interface). Rather than specifying policies explicitly for each
   interface of all devices in the network, policies are specified in
   terms of interface functionality.

   To describe these functionalities of an interface we use the concept
   of "Roles". A Role is simply a string that is associated with an
   interface. A given interface may have any number of roles
   simultaneously. Provisioning classes have an attribute called a
   "RoleCombinationö which is a lexicographically ordered set of roles.
   Instances of a given provisioning class are applied to an interface


                                                              [Page 2]


Framework Policy Information Base                            July 2001


   if and only if the set of roles in the role combination matches the
   set of the roles of the interface.

   Thus, roles provide a way to bind policy to interfaces without
   having to explicitly identify interfaces in a consistent manner
   across all network devices.  (The SNMP experience with ifIndex has
   proved this to be a difficult task.)  That is, roles provide a level
   of indirection to the application of a set of policies to specific
   interfaces. Furthermore, if the same policy is being applied to
   several interfaces, that policy need be pushed to the device only
   once, rather than once per interface, as long as the interfaces are
   configured with the same role combination.

   We point out that, in the event that the administrator needs to have
   unique policy for each interface, this can be achieved by
   configuring each interface with a unique role.

   The PEP sends all its Capability Set Names, Role Combinations,
   Policy Controlled Interfaces, and their relationships to the PDP in
   the initial COPS request (REQ) message.  The PDP can install new
   instances or change existing instances of these PRIs.  This
   operation can also occur in subsequent request messages generated in
   response to COPS state synchronization (SSQ) requests and local
   configuration changes.

   The comparing of roles (or role combinations) is case sensitive.

   By convention, when formatting the role-combination for exchange
   within a protocol message, within a PIB/MIB object's value, or as a
   printed value, the set is formatted in lexicographical order of the
   role's ASCII values; that is, the role that is first is formatted
   first. For example, "a+b" and "b+a" are NOT different role-
   combinations; rather, they are different formatting of the same
   role-combination, and hence for this example:
   - "a+b" is the valid formatting of that role-combination,
   - "b+a" is an invalid formatting of that role-combination.

   The role-combination of interfaces to which no roles have been
   assigned is known as the "null" role-combination.  (Note the
   deliberate use of lower-case letters for "null" so that it avoids
   confusion with the ASCII NULL character that has a value of zero but
   a length of one.)

   In an "install" or an "install-notify" class, the wildcard role-
   combination "*" can be used. In addition to providing for interface-
   specific roles, it also allows for other optimizations in reducing
   the number of role-combinations for which a policy has to be
   specified. For example:


   Suppose we have three interfaces:

     Roles A, B and R1 are assigned to interface I1

                                                              [Page 3]


Framework Policy Information Base                            July 2001


     Roles A, B and R2 are assigned to interface I2
     Roles A, B and R3 are assigned to interface I3

   Then, a PRI of a fictional IfDscpAssignTable that has the following
   values for its attributes:

     ifDscpAssignPrid    = 1
     ifDscpAssignRoles   = "*+A+B"
     ifDscpAssignName    = "4queues"
     ifDscpAssignDscpMap = 1

   will apply to all three interfaces, because "*" matches with R1, R2
   and R3. The policies can be assigned to an interface due to more
   than one wild-carded role combo matching a given interface's role
   combo string. The PDP should attempt to resolve conflicts between
   policies before sending policies to the PEP. In the situation where
   the PDP sends multiple policies to a PEP and they do conflict,
   either because of an error by the PDP or because of a device-
   specific conflict, then the PEP MUST reject the installation of the
   conflicting policies and return an error.

   Formally,
   - The wildcard Role is denoted by "*",
   - The "*" Role is not allowed to be defined as part of the role-
     combination of an interface as notified by the PEP to the PDP; it
     is only allowed in policies installed/deleted via COPS-PR from
     the PDP to the PEP.
   - For a policy to apply to an interface when the policy's role-
     combination is "*+a+b", then the interface's role-combination:
         - Must include "a" and "b", and
         - Can include zero or more other roles.
   - The wildcard character "*" is listed before the other roles as
     "*" is lexicographically before "a"; however, the wildcard matches
     any zero or more roles, irrespective of lexicographical order.
     For example: "*+b+e+g" would match "a+b+c+e+f+g"

   Note that the characters "+" and "*" MUST not be used in an
   interface Role. The Framework Role PIB module in section 4 of this
   document contains the Role and RoleCombination Textual Conventions.

3.1.1. An Example

   The functioning of roles might be best understood by an example.
   Suppose I have a device with three interfaces, with roles as
   follows:

        IF1: "finance"
        IF2: "finance"
        IF3: "manager"

   Suppose, I also have a PDP with two policies:

        P1: Packets from finance department (role "finance") get DSCP 5

                                                              [Page 4]


Framework Policy Information Base                            July 2001


        P2: Packets from managers (role "manager") get DSCP 6

   To obtain policy, the PEP reports to the PDP that it has some
   interfaces with role combination "finance" and some with role
   combination "manager".  In response, the PDP downloads policy P1
   associated with role combination "finance" and downloads a second
   policy P2 associated with role combination "manager".

   Now suppose the finance person attached to IF2 is promoted to
   manager and so the system administrator adds the role "manager" to
   IF2. The PEP now reports to the PDP that it has three role
   combinations: some interfaces with role combination "finance", some
   with role combination "manager" and some with role combination
   "finance+manager".  In response, the PDP downloads an additional
   third policy associated with the new role combination
   "finance+manager".

   How the PDP determines the policy for this new role combination is
   entirely the responsibility of the PDP.  It could do so
   algorithmically or by rule.  For example, there might be a rule that
   specifies that manager policy takes preference over department
   policy.  Or there might be a third policy installed in the PDP as
   follows:

        P3: Packets from finance managers (role "finance" and role
            "manager") get DSCP 7

   The point here is that the PDP is required to determine what policy
   applies to this new role combination and to download a third policy
   to the PEP for the role combination "finance+manager" even if that
   policy is the same as one already downloaded.  The PEP is not
   required (or allowed) to construct policy for new role combinations
   from existing policy.

3.2. Multiple PIB Instances

   [COPS-PR] supports multiple, disjoint, independent instances of the
   PIB to represent multiple instances of configured policy.  The
   intent is to allow for the pre-provisioning of policy that can then
   be made active by a single, short decision from the PDP.

   A COPS context can be defined as an independent COPS request state
   for a particular subject category (client-type).

   With the COPS-PR protocol, each of these states is identified by a
   unique client handle.  The creation and deletion of these PIB
   instances is controlled by the PDP as described in [COPS-PR]. A PEP
   must open only a single "request-state" for configuration for a
   given subject-category (client type). Any additional "request-
   states" at the PEP must be initiated by the PDP.

   Although many PIB instances may be configured on a device (the
   maximum number of these instances being determined by the device

                                                              [Page 5]


Framework Policy Information Base                            July 2001


   itself) only one of them can be active at any given time, the active
   one being selected by the PDP.  To facilitate this selection, the
   Framework PIB supports an attribute to make a PIB instance the
   active one and, similarly, to report the active PIB instance to the
   PDP in a COPS request message. This attribute is in the Incarnation
   Table described below.

   Setting the attribute frwkPibIncarnationActive to 'true' in one PIB
   instance MUST ensure that the attribute is 'false' in all other
   contexts.

3.3. Reporting and Configuring of Device Capabilities

   Each network device providing policy-based services has its own
   inherent capabilities.  These capabilities can be hardware specific,
   e.g., an ethernet interface supporting input classification, or can
   be statically configured, e.g., supported queuing disciplines.
   These capabilities are organized into some PEP default Interface
   Capability Set, with each Capability Set associated with a set of
   Role Combinations, each Role Combination associated with a set of
   interfaces.  After receiving the PEP default setting for the PEP
   device capabilities, the PDP can change them.  These capabilities
   are communicated to the PDP when initial policy is requested by the
   PEP. Knowing device capabilities, the PDP can send the provisioning
   instances (PRIs) relevant to the specific device, rather than
   sending the entire PIB.

   The PIB indicates which capabilities the PEP must report to the PDP
   by means of the PIB-ACCESS clause as described in [SPPI].

3.4. Reporting of Device Limitations

   To facilitate efficient policy installation, it is important to
   understand a device's limitations in relation to the advertised
   device capabilities. Limitations may be class-based, e.g., an
   "install" class is supported as a "notify" or only a limited number
   of class instances may be created, or attribute-based. Attribute
   limitations, such as supporting a restricted set of enumerations or
   requiring related attributes to have certain values, detail
   implementation limitations at a fine level of granularity.

   A PDP can avoid certain installation issues in a proactive fashion
   by taking into account a device's limitations prior to policy
   installation rather than in a reactive mode during installation. As
   with device capabilities, device limitations are communicated to the
   PDP when initial policy is requested.

   Reported device limitations may be accompanied by guidance values
   that can be used by a PDP to determine acceptable values for the
   identified attributes.

5. Summary of the Framework PIB

   The Framework PIB comprises of three groups:

   1. Base PIB classes Group

      This contains PRCs intended to describe the PRCs supported
      by the PEP, PRC and/or attribute limitations and its current
      configuration.

      PRC Support Table

        As the technology evolves, we expect devices to be enhanced
        with new PIBs, existing PIBs to add new PRCs and existing PRCs
        to be augmented or extended with new attributes.  Also, it is
        likely that some existing PRCs or individual attributes of PRCs
        will be deprecated. The PRC Support Table describes the PRCs
        that the device supports as well as the individual attributes
        of each PRC.  Using this information the PDP can potentially
        tailor the policy to more closely match the capabilities of the
        device. The PRC Support Table instances are specific to the
        particular Subject Category (Client-Type). That is, the PRC
        Support Table for Subject Category 'A' will not include
        instances for classes supported by the Subject Category 'B'.
        Note that the COPS client-type [COPS] used for Framework PIB
        PRIs sent/received over COPS-PR MUST be the unique SUBJECT-
        CATEGORY number assigned for the area of policy being managed
        (e.g. QoS, Security etc).
        The PEP MUST ignore the attributes that it reports as not
        Supported in the decision from the PDP. The PEP SHOULD not send
        duplicate PRC support instances in a COPS Request and the PDP
        MUST ignore duplicate instances and MUST use the first instance
        received for a supported PRC in a COPS Request.

      PIB Incarnation Table

        This table contains exactly one row (corresponding to one PRI)
        per context.  It identifies the PDP that was the last to
        download policy into the device and also contains an identifier
        to identify the version of the policy currently downloaded.
        This identifier, both its syntax and value, is meaningful only
        to the PDPs.  It is intended to be a mechanism whereby a PDP,
        on connecting to a PEP, can easily identify a known incarnation
        of policy. The incarnation PRC also includes an attribute to
        indicate which context is the active one at the present time.
        The incarnation instance is specific to the particular Subject
        Category (Client-Type).

      Component Limitations Table

        Some devices may not be able to implement the full range of
        values for all attributes.  In principle, each PRC supports a
        set of errors that the PEP can report to the PDP in the event

                                                              [Page 9]

        that the specified policy is not implementable.  It may be
        preferable for the PDP to be informed of the device limitations
        before actually attempting to install policy, and while the
        error can indicate that a particular attribute value is
        unacceptable to the PEP, this does not help the PDP ascertain
        which values would be acceptable. To alleviate these
        limitations, the PEP can report some limitations of attribute
        values and/or classes and possibly guidance values for the
        attribute in the Component Limitations Table

      Device Identification Table

        This class contains a single provisioning instance that
        contains device-specific information that is used to facilitate
        efficient policy installation by a PDP. The instance of this
        class is reported to the PDP in a COPS request message so that
        the PDP can take into account certain device characteristics
        during policy installation.

   2. Device Capabilities group

      This group contains the PRCs that describe the characteristics of
      interfaces of the device and the Role Combinations assigned to
      them.

      Interface Capabilities Set Table

        The interfaces the PEP supports are described by rows in
        this table (frwkIfCapSetTable).  Each row, or instance of this
        class, associates a unique interface name with a set of
        capabilities that the interface supports. The unique name is
        used to form a set of capabilities that the name represents.
        The capability references can specify instances in relevant
        capability tables in any PIB. The PEP notifies the PDP of these
        interface names and capabilities and then the PDP configures
        the interfaces, per role combination. The unique name
        (IfCapSetName) is not to be confused with the IfType object in
        MIB-II [STD17].

      Interface Capability and Role Combo Table

        The Interface Capabilities Set Table (explained above)
        describes the interfaces the PEP supports by their
        capabilities, by assigning the capability sets a unique name.
        It is possible to tailor the behavior of interfaces by
        assigning specific roles to the capability sets. This allows
        interfaces with the same capability sets to be assigned
        different policies, based on the current roles assigned to
        them. At the PDP, configuration is done in terms of these
        interface capability set names (ifCapSetName) and the role
        combinations assigned to them. Thus, each row of this
        class is a <interface capability set name, Role Combo> two-
        tuple, that indicates the roles that have been assigned to a

                                                             [Page 10]


Framework Policy Information Base                            July 2001


        particular capability set (as identified by IfCapSetName). The
        ifCapSetName is the grouping attribute used to form a set of
        role combinations that apply to this capability set.

      Interface and Role Combination Table

        The Interface and Role Combination Table describes the
        association between specific interfaces with each role
        combination.  It answers the questions of æwhich interfaces
        have a specific role combination?Æ and æwhat role combination
        a specific interface is a part of?Æ.  The Interface and Role
        Combination Table entries each contains a <ifIndex, Role Combo>
        two-tuple to accomplish this mapping.


   3. Classifier group

      This group contains the IP and IEEE 802 Classifier elements. The
      set of tables consist of a Base Filter table that contains the
      Index InstanceId and the Negation flag for the filter. This
      frwkBaseFilterTable is extended to form the IP Filter table and
      the 802 Filter table [802]. Filters may also be defined outside
      this document and used to extend the Base Filter table.

      The Extended classes do not have a separate Index value.
      Instances of the extended classes have the same indices as their
      base class instance. Inheritance is achieved using the EXTENDS
      keyword as defined in [SPPI].

           A value of 'enumMin(6)' means that the guidance
           attribute provides data related to the lowest
           enumeration acceptable for the value of the
           identified component. A corresponding
           class instance specifying the 'enumMax(7)'
           value is required in conjunction with this sub-type.

           A value of 'enumMax(7)' means that the guidance

           identified component. A corresponding
           class instance specifying the 'enumMin(6)'
           value is required in conjunction with this sub-type.

           A value of 'enumOnly(8)' means that the guidance
           attribute provides data related to a single
           enumeration acceptable for the value of the
           identified component.

           A value of 'valueOnly(9)' means that the guidance
           attribute provides data related to a single
           value that is acceptable for the identified
           component.

           A value of 'bitMask(10)' means that the guidance
           attribute is a bit mask such that all the combinations of
           bits set in the bitmask are acceptable values for the
           identified component which should be an attribute of type
           'BITS'.

           For example, an implementation of the frwkIpFilter class may
           be limited in several ways, such as address mask, protocol
           and Layer 4 port options. These limitations could be

           The value of this object represents a mask that is logically

           value to be compared against the frwk802FilterSrcAddr
           address. A zero bit in the mask thus means that the
           corresponding bit in the address always matches. The
           frwk802FilterSrcAddr value must also be masked using this
           value prior to any comparisons.

           The length of this object in octets must equal the length in
           octets of the frwk802FilterSrcAddr. Note that a mask with no
           bits set (i.e., all zeroes) effectively wildcards the

7. Security Considerations

   It is clear that this PIB is used for configuration using [COPS-PR],
   and anything that can be configured can be misconfigured, with
   potentially disastrous effect. At this writing, no security holes
   have been identified beyond those that the COPS base protocol
   security is itself intended to address. These relate primarily to
   controlled access to sensitive information and the ability to
   configure a device - or which might result from operator error,
   which is beyond the scope of any security architecture.

   There are a number of provisioning classes defined in this PIB that
   have a PIB-ACCESS clause of install (read-create). Such objects may
   be considered sensitive or vulnerable in some network environments.
   The support for "Install" decisions sent over [COPS-PR] in a non-
   secure environment without proper protection can have a negative
   effect on network operations. There are a number of provisioning
   classes in this PIB that may contain information that may be
   sensitive from a business perspective, in that they may represent a
   customer's service contract or the filters that the service provider
   chooses to apply to a customer's ingress or egress traffic. There
   are no PRCs that are sensitive in their own right, such as passwords
   or monetary amounts. It may be important to control even
   "Notify"(read-only) access to these PRCs and possibly to even
   encrypt the values of these PRIs when sending them over the network
   via COPS-PR. The use of IPSEC between the PDP and the PEP, as
   described in [COPS], provides the necessary protection against
   security threats. However, even if the network itself is secure,
   there is no control as to who on the secure network is allowed to
   "Install/Notify" (read/change/create/delete) the PRIs in this PIB.

   It is then a customer/user responsibility to ensure that the PEP/PDP
   giving access to an instance of this PIB, is properly configured to
   give access to the PRIs only to those principals (users) that have
   legitimate rights to indeed "Install" or "Notify" (change/create/
   delete) them.
