Abstract

   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.
