NVO3 Operational Requirements
draft-ashwood-nvo3-operational-requirement-02
Abstract
This document provides framework and requirements for Network
Virtualization over Layer 3 (NVO3) Operations, Administration, and
Maintenance (OAM). This document for the most part gathers
requirements from existing IETF drafts and RFCs which have already
extensively studied this subject for different data planes and
layering. As a result this draft is high level and broad. We begin
to ask which are truly required for NVO3 and expect the list to be
narrowed by the working group as subsequent versions of this draft
are created.
Status of this Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at http://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."
This Internet-Draft will expire on July 5, 2013.
