NAME OF I-D:
http://search.ietf.org/internet-drafts/draft-many-carrier-framework-uni-00.txt


SUMMARY
   This contribution describes a carriers optical services framework
   and associated requirements for the User-Network Interface (UNI). It
   is intended to provide carrier specific service requirements for the
   automatic switched optical networks to guide the on-going efforts in
   developing the standard UNI and other interfaces to the optical layer
   control plane. The objective is to define the optical networking and
   service functions as service building blocks that will enable the 
   carriers to mix and match them to build their own valued optical network 
   services. This contribution also provides requirements for the optical
   control and management plane of the optical switched network. In this 
   contribution, we focused on topics of particular interest or concern 
   to the carrier community. This is a work-in-progress document and is 
   expected to evolve in near term as new requirements are identified 
   and further studied.

WHY IS IT TARGETED AT THIS WG
This contribution address the issues related to the following IPO WG 
work items:
  -  Document the use of existing framing methods for IP over optical 
   dataplane and control channels, and as necessary specify additional 
   framing methods. 

  - Identify and document the characteristics of the optical transport 
  network that are important for selecting paths for optical channels, 
  setting-up optical channels, and tearing-down optical channels. 

This contribution documents the generic services framework over 
an optical transport network (OTN) for the IP layer and others, 
and  provides functional requirements for enabling optical layer 
services. Based on the last WG proposal favored by majority, 
this document  will be consolidated with 

draft-ishimatsu-ipo-lightpath-scrty-00.txt

into an IPO WG document, which address the security issues related to 
the optical layer services.

In addition, some of the requirements in draft-freeland-octrl-cons-01.txt
can also be incorporated into the document.

JUSTIFICATION

In order to define the IP over Optical (IPO) technology, it is important
to understand the optical layer service requirements as well as the
enabling optical networking functions, which combined can be used 
to create optical layer service for the IP layer and other client
layers. This I-D document address exactly the issues from carrier's 
perspective.
