               Multiple Provisioning Domain Architecture

Abstract

   This document is a product of the work of the Multiple Interfaces
   Architecture Design team.  It outlines a solution framework for some
   of the issues experienced by nodes that can be attached to multiple
   networks simultaneously.  The framework defines the concept of a
   Provisioning Domain (PvD), which is a consistent set of network
   configuration information.  PvD-aware nodes learn PvD-specific
   information from the networks they are attached to and/or other
   sources.  PvDs are used to enable separation and configuration
   consistency in the presence of multiple concurrent connections.
