Revision 0.0
Status of this Memo
This document is an Internet-Draft and is in full conformance with all
provisions of Section 10 of RFC2026.
Internet-Drafts are working documents of the Internet Engineering Task
Force (IETF), its areas, and its working groups. Note that other groups
may also distribute working documents as Internet-Drafts.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet- Drafts as reference material
or to cite them other than as "work in progress."

Abstract
The MIB Module described in this document provides a
conceptual layer between high-level "network-wide" policy
definitions that affect configuration of the differentiated
services (DiffServ) subsystem and the instance-specific
information that would include such details as the
parameters for all the queues associated with each interface
in a system. This essentially provides an interface for
configuring DiffServ at a conceptually higher layer than
that of the DiffServ MIB [1].
1. TODOs
* administrivia: various template things need to be put in (the
Internet Draft March 2000
internet standard management framework, appropriate references,
security boilerplate, verify intellectual property clause, the MUST,
MAY, SHOULD stuff, etc. There are unresolved references.
* This document is little more than a skeleton at this point. The
convergence of the documents being published in parallel with this
document are a necessary precursor to putting any real
flesh on this document.
2. Introduction
This memo defines a MIB module which can be used to convey information
about desired network-wide DiffServ-based policy behavior. This module
is designed to integrate with the Policy-based Management MIB module [2]
as well as the DiffServ MIB module published by the DiffServ working
group [1]. Together these three documents represent an instance of an
integrated architecture for both device specific and network-wide policy
management which is fully integrated with the Internet Standard
Management Framework.
This is the first of what is expected to be a wide number of other
network-wide policy modules to be developed in the future in a wide
range of areas.
Within the DiffServ architecture a MIB module is already defined [1]
that operates on a device level. This MIB should create a coherent
policy configuration management view as an umbrella over this "device
specific" MIB. That is, this MIB provides a conceptual API for
configuration of DiffServ parameters in a device at a higher level than
the DiffServ MIB.
While the intent of this document is similar to that being defined by
Policy Information Base documents to be used with COPS-PR [????], the
degree of reuse from those documents is unclear.

4. Definitions
4.1. Terms Defined Elsewhere
Two companion documents, the Best Current Practices document [3] and the
Policy-based Management MIB [2] define terms fundamental to the
architecture used for policy-based management using SNMP. These terms
are:
- insert the terms defined
Other IETF working groups (such as the POLTERM working group) also have
definitions for some of the same concepts. To the extent that it is
possible, those definitions will be harmonized with these.
4.2. Definitions Specific to this Document
The following definitions are specific and required only for this
document:
- any definitions required will be placed here
5. Relationship to other MIBs
In this section we describe the relationship to other MIB modules. The
overall architecture used for policy configuration management is
described in [????]
5.1. The Policy-based Management MIB module
The Policy-based Management MIB module defines MIB tables which are used
for representing the capabilities of a device with respect to policy
management. Examples of information which is held in these tables are
which kinds of policy can be configured at this managed entity (e.g.,
DiffServ, VPN, etc.), the configured roles of the elements in these
managed entities, as well as policy filters and policy actions
configured in the managed entity.
The DiffServ Policy MIB references information in the(se) table(s) in
carrying out configuration of the layer below.

Internet Draft March 2000
TBD: describe precisely which objects are referred.
5.2. The DiffServ MIB module
The DiffServ MIB[??] provides all of the managed objects required for
configuring DiffServ parameters on a particular device. It is this
configuration which MAY be done via the API provided by the DiffServ
Policy MIB.
5.3. Diffserv Policy MIB module
The DiffServ Policy MIB will configure the underlaying differentiated
services architecture via the DiffServ MIB which defines the managed
objects for the DiffServ architecture.
TBD: the direct relationships and objects that are referred to.
6. MIB Module Design
In this section the overall design of the DIFFSERV-POLICY-MIB is
described. The first part will describe how this module needs to be
placed within the overall architecture. However, it is recognised that
in the future a MIB like this will also be developed for VPNs, or
security.
7. Managed objects definitions (MIB)
There is not yet a MIB. The first draft of the MIB should be available
prior to the Adelaide meeting. If you are interested in this work,
please be certain that you are on the working group mailing list.
This MIB will, as previously stated, provide a glue layer "API" for
managing DiffServ parameters in a "network-wide" manner.
