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 policy rule classes and instances of these classes residing
in a virtual information store called the Policy Information Base (PIB).

This document specifies a set of policy rule classes specifically for
configuring QoS Policy for Differentiated Services [DSARCH].

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.  The PRCs defined in this DiffServ QoS PIB
are intended for use by the COPS-PR QoS client type.  Furthemore, these
PRCs are in addition to any other PIBs that may be defined for the QoS
client type in the future, as well as the PRCs defined in the Framework
PIB [FR-PIB]



3.  DiffServ PIB Concepts

3.1.  Filters, Filter Groups and Classifiers

The basis of differential QoS treatment of packets is a filter. This is
simply a general specification for matching a pattern to appear in
packets belonging to flows, e.g. microflows or bandwidth aggregates.
Associated with each filter is a permit/deny flag which effectively
gives a negation operation.

Sets of these filters are used to create classifiers. Classifiers are
applied to interfaces with a direction flag to indicate an ingress or
egress classifier. Filters are combined, in order, into filter groups;





                                                                [Page 2]


DiffServ QoS Policy Information Base                          March 2000


filter groups are then combined, in order, to build a classifier. This
allows a rudimentary classification grammar to be defined. On input,
each packet is checked against the ingress classifier on the interface.
Similarly, on output each packet is checked against the egress
classifier on the interface. The result of the classifier then feeds
into appropriate meters and actions to be applied to packets.

For each classifier, the packet is checked against the set of filter
groups in the appropriate order. The detailed operation of the PIB
syntax is as follows. If a packet matches a filter in the first filter
group of a classifier and the sense is "permit" then the subsequent
meters and actions associated with that classifier are applied to that
packet and no further filters are compared. If the sense is "deny" then
the rest of the filters in the current filter group are skipped and
operation proceeds with the first filter of the next filter group. If
the packet does not match any of the filters in the filter group then
the next filter group is tried. This process is continued until a
definitive match is obtained. Each classifier must cover all possible
matches i.e., it must be complete.

3.2.  Applying QoS Policy Using Targets

The task of applying QoS policy within a network requires the
specification of several components. The flows to which QoS policy
should be applied must be identified. The interfaces of the device on
which the policy should be enforced must be known. A certain set of
parameters to support flow metering is also required. The combination of
these components provides the target against which QoS policy is to be
applied. Within the context of the QoS PIB, the association between
these components is defined efficiently using the Target class.

The Target class serves to logically link several other QoS policy
classes. Flow classification rules, specifying behavior aggregate (BA)
or multi-field (MF) classification parameters, are indirectly identified
using the PRC for the appropriate classification class (e.g., IP, 802)
coupled with an identifier for a specific classifier. Interface
information is specified using the role combination tag, defined in the
Interface Type class, to identify the group of interfaces on which
classification is to be performed. The direction of packet flow on the
identified interfaces is provided as well. A link to the metering
component is provided using the PRC for the appropriate metering class
instance.

Once a target has been defined, actions based on the classification and
metering phases must be specified. Action class instances are linked





                                                                [Page 3]


DiffServ QoS Policy Information Base                          March 2000


with the Target entry through the associated Meter class instance.  A
precedence component is also provided so that a definitive order of
evaluation may be defined for Target class instances being applied to
the same interface role and flow direction targets. The Target class
thus functions as the integration point for the range of components used
for the application of QoS policy.

3.3.  Interface Modeling with Queue Sets

The traffic processing capabilities of an interface are determined by
the queuing resources that are associated with the interface.  These
capabilities are represented abstractly using queue sets.  A queue set
is comprised of one or more individual queues.  The PDP creates the
queue sets, configures the parameters of the individual queues,
configures the scheduling discipline to be used to schedule the queues
and then assigns a queue set to each <interface type, role combination>
tuple.  In this way, the PDP sets the scheduling policy for each
interface based on the role combination of the interface and the type of
the interface.

In order for the PDP to configure a queue set that can be properly
realized by an interface, the PEP reports to the PDP the types of
interfaces it has together with various capabilities and configuration
limits (such as the maximum number of queues an interface could support)
of the interface types.

It should be emphasized that the PDP does not configure individual
interfaces directly.  Rather, it configures them indirectly by
specifying the configuration for each interface type and role
combination pair.  It is the responsibility of the PEP to apply the
queue set characteristics, and hence the interface scheduling
configuration, to the individual interfaces on the basis of the type and
role combination information.


3.3.1.  Queue Scheduling

There are two basic scheduling disciplines supported by queue sets:
priority queueing and weighted fair queueing.  To support these, each
queue is assigned a priority which is then used to determine a strict
processing order between queues.  However, several queues may be
assigned the same priority.  In this case, these queues form a group,
called a priority group, and are scheduled using WFQ.  In other words,
service is given to the priority group with the highest priority that
has any non-empty queue.  Within a priority group queues are serviced





                                                                [Page 4]


DiffServ QoS Policy Information Base                          March 2000


using WFQ.


3.3.2.  Assigning Packets To Queues and Thresholds

In keeping with the DiffServ model of classifying packets into behaviour
classes and then providing service suitable for that behaviour, packets
are assigned to queues on the basis of their final DSCP values.
Furthermore, each queue is configured with a set of thresholds to
support multiple discard priorities for the PHBs in a PHB group.
Packets are assigned to thresholds within a queue on the basis of their
DSCPs.  The PDP is responsible for this assignment of DSCP values to
queues and the associated thresholds.


3.3.3.  Hierarchies of Queues

Sometimes policy may require hierachies of queues.  For example, a
department might has some set of traffic classes with a defined
scheduling policy between these classes.  Multiple departments might
then share a link with there being a defined scheduling policy between
traffic from the various depertments.

The PIB does not support hierarchical queueing at this time.  However,
we expect to add this support in the future by allowing the traffic from
one queue set to feed into the queues of another queue set.



3.4.  IP Mapping to and from Layer 2

The PIB specifies QoS policy by assigning DSCP values to specific
queues, but in order to provide a complete QoS picture, the PIB must
consider that not all devices on the network are DiffServ capable, i.e.,
capable of setting/inspecting a packet's DSCP value.  Specifically, the
network might include layer 2 devices (switches) that can only support
IEEE 802.1p classes of service. In order to support network
configuration that consists of DiffServ capable devices and devices that
can only support IEEE 802.1p, the PIB has included a mapping table that
can allow the DSCP values to be mapped to specific IEEE 802.1p tag
values.



   DSCP ---------- DSCP     -------- DSCP     ---------- DSCP





                                                                [Page 5]


DiffServ QoS Policy Information Base                          March 2000


  ----->|diffserv|--------->|L2    |--------->|diffserv|------>
        | router | 802.1p   |switch| 802.1p   | router | 802.1p
        ---------- priority -------- priority ---------- priority


A second case exists where packets coming into the network are arriving
from a non-DiffServ enabled device and no DSCP exists with in the
packet, but an 802.1p tag does exist. In the case where the DiffServ
device has the ability to set a DSCP in the packet, the DiffServ router
can map the layer 2 tag into a DSCP value. The PIB supports a mapping
table that can be used to map from the layer 2 tag to a DSCP value.
This mapping would be configured to apply to those ports where the
upstream device marks packets using a L2 802.1p tag as shown in the
figure below.

        ----------          ------------ DSCP
     -->| L2     |--------->| diffserv |------->
     -->| switch | 802.1p   |  router  | 802.1p
        ---------- priority ------------ priority


Alternatively, the DiffServ router can have policies applied to it that
cause it to reclassify the incoming packet using a MF classifier,
ignoring the incoming 802.1p tag.


4.  Summary of the DiffServ PIB

The DiffServ PIB consists of two modules.  The first, DIFFSERV-BASE-PIB
contains all the base PRCs for setting DiffServ policy, queues,
classifiers, meters, etc.,  and also contains filters for matching IP
packets.  The second, the DIFFSERV-802-PIB contains PRCs to map the IEEE
802.3 class of service values to DiffServ code points and filters for
matching on the datalink headers of 802.3 frames.  Devices are not
required to support the second module.

These two modules comprise several groups which are summarized in this
section.

QoS Interface Group
     This group consists of PRCs to indicate to the PDP the types of
     interface supported on the PEP in terms of their QoS capabilities
     and PRCs that the PDP can install in order to configure these
     interfaces (queues, scheduling parameters, buffer sizes, etc.) to
     affect the desired policy.  This group describes capabilities in





                                                                [Page 6]


DiffServ QoS Policy Information Base                          March 2000


     terms of the types of interfaces and takes configuration in terms
     of interface types and role combinations [FR-PIB]; it does not deal
     with individual interfaces on the device.

QoS Metering Group
     This group contains configuration of meters.  These meters can then
     be used to by target classes to specify metering policy.

QoS Action Group
     This group contains the policies that define the action to be taken
     after the result of the classification and metering. This group
     also contains the policies that associate the classifiers, meters
     and actions.

IP Classification and Policing Group
     This group contains the policies that define the IP classifier
     elements.

802 Config Group
     This group configures the relationship between 802.3 class of
     service values and DiffServ codepoints.

802 Classification and Policing Group
     This group contains the policies that define the IEEE 802
     classifier elements.


5.  PIB Operational Overview

This section provides an operation overview of configuring DiffServ QoS
policy.

After initial PEP to PDP communication setup, using [COPS-PR] for
example, the PEP will provide to the PDP the PIB Policy Rule Classes
(PRCs), interface types, and interface type capabilities it supports.

The PRCs supported by the PEP are reported to the PDP in the PRC Support
Table, policyPrcSupportTable defined in the framework PIB.  Each
instance of the policyPrcSupportTable indicates a PRC that the PEP
understands and for which the PDP can send class instances as part of
the policy information.

The interface types the PEP supports are described by rows in the
interface type table, qosIfTypeTable.  Each row, or instance of this
class describes the characteristics of an interface type.  The PEP





                                                                [Page 7]


DiffServ QoS Policy Information Base                          March 2000


informs the PDP of these interface types and then the PDP configures the
interfaces, per role combination, by means of installing queue sets.

The PDP, with knowledge of the PEP's capabilities, then provides the PEP
with:

 (1)   Administration domain policy information in
            qosIfDscpAssignTable
            qos802DscpMappingTable
            qos802CosToDscpTable

 (2)   Interface type and role specific IP policy information in
            qosIpAceTable
            qosIpAclDefinitionTable
            qosActionTable
            qosTargetTable
            qosMeterTable

 (3)   Interface type and role specific IEEE 802 policy information in
            qos802AceTable
            qos802AclDefinitionTable

Instances of the qosTargetTable define how the Traffic Conditioning
Elements are combined into Traffic Conditioning Blocks, as described in
[MODEL].  Each instance of the qosTargetTable applies to an interface
type defined by its roles and direction (ingress or egress).  This is
pictured in the following diagram where the InterfaceRoles X, and Y
would be used by the network device to associate the traffic
conditioning block with the interfaces needing each of thess policies.

              Figure 7.1  DiffServ PIB Table Relationships

Notice in the above diagram, IEEE 802 type classifiers are intermixed
with the IP type classifiers, sharing the same pool of Traffic
Conditioning Elements.  The qosTargetTable allows use of heterogeneous
classifiers with same instance of qosMeterTable.  Using IP and IEEE 802
classifiers together is just one example.  Other types of classifiers
may be used heterogeneously.

After receiving the PIB, the PEP will associate the Classifier, Meter
and Action with the corresponding interfaces supporting the specific
interface type and roles.

        the same value for all queues in the priority group.  Several
        general purpose and well-known queuing disciplines are
        supported by this attribute. Queuing disciplines that differ
        from those that are supported by this attribute are specified
        by setting this attribute to other(1) and augmenting this PRC
        with additional attributes to specify the desired service
        discipline.

        As an example, an interface that is associated with a queue
        set supporting two priority queues and three queues that are
        serviced using WFQ would be modeled as follows:

             Id    Q Discipline  Q Drain Size  Priority Group
             22         na(1)         -              3
             23         na(1)         -              2
             24        wfq(3)        500             1
             25        wfq(3)        350             1
             26        wfq(3)        150             1

        The queue set presented in this example would service
        all queued traffic in queue 22 first, followed by all of
        the queued traffic in queue 23. Next the queued traffic
        in queues 24 through 26 would be serviced in a round
        robin fashion with queue 24 receiving 50% of the available
        bandwidth, queue 25 receiving 35% of the available
        bandwidth and queue 26 receiving 15% of the available
        bandwidth. This example is presented for expository
        purposes and has been simplified accordingly.

        Note that, in this example, queues 24, 25 and 26 form a
        priority group.  The qosIfQueueDrainSize attribute is used
        to determine the additional processing characteristics of the
        individual queues in a this priority group."

        "This attribute identifies the ACL that is associated

        class instances in a specific ACL Definition table
        where ACLs, and their associated ACEs, are defined.
        For example, instances in the qosIpAclDefinitionTable
        are identified by setting the value of this object
        equal to the qosIpAclDefinitionAclId of the instances
        being targeted. This value, together with the value of
        the corresponding qosTargetAclType attribute,
        uniquely identifies one or more instances of a specific
        ACL Definition class.

        Attempting to specify an unknown ACL class instance will
        result in an appropriate error indication being returned
        to the entity that is attempting to install the conflicting

        "This attribute identifies the 802 ACE in the qos802AceTable
        that is associated with the 802 ACL specified by
        qos802AclDefinitionAclId object. The corresponding instance
        in the qos802Ace class must exist prior to being associated
        with a 802 ACL.

        Attempting to specify an unknown class instance will result
        in an appropriate error indication being returned to the
        entity that is attempting to install the conflicting entry.
        For example, a 'priUnknown(2)' error indication is returned
        to the policy server in this situation."

qos802AclDefinitionAceOrder OBJECT-TYPE
    SYNTAX         Unsigned32
    STATUS         current
    DESCRIPTION
        "The precedence of the 802 ACE, identified via the
        qos802AclDefinitionAceId object, with regard to evaluation
        order. The precedence determines the order of evaluation of
        this ACE in relation to related 802 ACEs that are associated
        with an ACL. An ACE with a given precedence order in the
        access control list is evaluated before one with a higher-
        valued precedence order.

        Precedence values within a group must be unique otherwise
        instance installation will be prohibited and an error
        value will be returned.

        Note that qos802AclDefinitionAceOrder values within a given
        ACL need not be contiguous."

7.  Security Considerations

The information contained in a PIB when transported by the COPS protocol
[COPS-PR] may be sensitive, and its function of provisioning a PEP
requires that only authorized communication take place.  The use of
IPSEC between PDP and PEP, as described in [COPS], provides the
necessary protection against these threats.
