Abstract
This document is a glossary of policy-related terms. It provides
abbreviations, explanations, and recommendations for use of these
terms. The document takes the approach and format of RFC 2828, which
defines an Internet Security Glossary. The intent is to improve the
comprehensibility and consistency of writing that deals with network
policy, particularly Internet Standards documents (ISDs).

1. Introduction
This document provides abbreviations, definitions, and explanations
of terms related to network policy. All definitions are provided in
Section 3, with the terms listed in alphabetical order.
The intent is to improve the comprehensibility and consistency of
Internet Standards documents (ISDs) -- i.e., RFCs, Internet-Drafts,
and other material produced as part of the Internet Standards Process
[RFC2026]. Benefits across the ISDs are well-stated in the
Introduction to RFC 2828 [RFC2828]:
o "Clear, Concise, and Easily Understood Documentation" - Requires
that the set of terms and definitions be consistent, self-
supporting and uniform across all ISDs.
o Technical Excellence - Where all ISDs use terminology accurately,
precisely, and unambiguously.
o Prior Implementation and Testing - Requires that terms are used in
their plainest form, that private and "made-up" terms are avoided
in ISDs, and that new definitions are not created that conflict
with established ones.
o "Openness, Fairness, and Timeliness" - Where ISDs avoid terms that
are proprietary or otherwise favor a particular vendor, or that
create a bias toward a particular technology or mechanism.
Common and/or controversial policy terms are defined. These terms
are directly related and specific to network policy.
Wherever possible, this document takes definitions from existing
ISDs. It should be noted that:
o Expired Internet-Drafts are not referenced, nor are their
terminology and definitions used in this document.

o Multiple definitions may exist across the ISDs. Each definition
is listed, with its source.
2. Explanation of Paragraph Markings
Section 3 marks terms and definitions as follows:
o Capitalization: Only terms that are proper nouns are capitalized.
