Abstract

The widespread interest in provider-provisioned Virtual Private Network (VPN) solutions lead to memos proposing different and overlapping solutions. The IETF working groups (first Provider Provisioned VPNs and later Layer 2 VPNs and Layer 3 VPNs) have discussed these proposals and documented specifications. This has lead to the development of a partially new set of concepts used to describe the set of VPN services.

Abstract

   The widespread interest in provider-provisioned Virtual Private
   Network (VPN) solutions lead to memos proposing different and
   overlapping solutions.  The IETF working groups (first Provider
   Provisioned VPNs and later Layer 2 VPNs and Layer 3 VPNs) have
   discussed these proposals and documented specifications.  This has
   lead to the development of a partially new set of concepts used to
   describe the set of VPN services.

   To a certain extent, more than one term covers the same concept, and
   sometimes the same term covers more than one concept.  This document
   seeks to make the terminology in the area clearer and more intuitive.
