David Partain Ericsson Harrie Hazewinkel TBD The DiffServ Policy MIB March 8, 2000 draft-ietf-snmpconf-diffpolicy-00.txt 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." The list of current Internet-Drafts can be accessed at http://www.ietf.org/ietf/1id-abstracts.txt The list of Internet-Draft Shadow Directories can be accessed at http://www.ietf.org/shadow.html. 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. 3. The Internet Standard Management Framework Insert framework boilerplate here Expires September 1999 SNMPCONF Working Group [Page 2] Internet Draft March 2000 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. Expires September 1999 SNMPCONF Working Group [Page 3] 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. 8.
