This memo describes an SMIv2 (Structure of Management Information version 2) MIB for a device implementing the Differentiated Services Architecture. It may be used both for monitoring and configuration of a router or switch capable of Differentiated Services functionality. Baker, et. al. Standards Track [Page 1] RFC 3289 Differentiated Services MIB May Baker, et. al. Standards Track [Page 2] RFC 3289 Differentiated Services MIB May 2002 Baker, et. al. Standards Track [Page 5] RFC 3289 Differentiated Services MIB May 2002 3. MIB Overview The Differentiated Services Architecture does not specify how an implementation should be assembled. The [MODEL] describes a general approach to implementation design, or to user interface design. Its components could, however, be assembled in a different way. For example, traffic conforming to a meter might be run through a second meter, or reclassified. This MIB models the same functional data path elements, allowing the network manager to assemble them in any fashion that meets the relevant policy. These data path elements include Classifiers, Meters, Actions of various sorts, Queues, and Schedulers. In many of these tables, a distinction is drawn between the structure of the policy (do this, then do that) and the parameters applied to specific policy elements. This is to facilitate configuration, if the MIB is used for that. The concept is that a set of parameters, such as the values that describe a specific token bucket, might be configured once and applied to many interfaces.

This document describes a Policy Information Base (PIB) for a device implementing the Differentiated Services Architecture. The provisioning classes defined here provide policy control over resources implementing the Differentiated Services Architecture. These provisioning classes can be used with other none Differentiated Services provisioning classes (defined in other PIBs) to provide for a comprehensive policy controlled mapping of service requirement to device resource capability and usage.

Status of this Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
