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.
