NAME OF I-D:

SUMMARY

 This draft considers the optical network service model referred
to as the "domain services" model [1]. Under this model, the optical 
network provides a set of well-defined services to clients (IP and    
others). The signaling and routing interface between the client and 
optical networks is referred to as the User-Network Interface (UNI).
This draft describes the services provided over the UNI, and the
requirements on any signaling protocol used to invoke the services.

This draft reflects ongoing work at the Optical Interworking Forum 
(OIF) on the optical UNI (similar work is being carried out by the 
Optical Domain Services Interconnect (ODSI) coalition [2]).
 The relevance of this draft to the IETF is two-fold.  
First, for the signaling portion of the optical UNI, 
extensions of two MPLS signaling protocols are presently 
under consideration in the OIF: RSVP with TE extensions and LDP. 
The objective of this draft is to guide the adaptation of 
these protocols for UNI signaling. Second, to 
harmonize the signaling of UNI originated lightpath 
requests and peer model lightpath establishment mechanisms [1], 
alignment between OIF and IETF lightpath parameters and 
signaling functionality is desirable. This draft aims 
to serve this purpose. The content of this draft is 
expected to evolve as work progresses on the optical UNI.

WHERE DOES IT FIT IN THE PICTURE OF THE SUB-IP WORK

This draft belongs in the IPO WG, as it describes services and
signaling requirements for the UNI. Specific signaling extensions may
be dealt with in CCAMP or MPLS. 

WHY IS IT TARGETED AT THIS WG

   This document describes services and signaling requirements for the
   optical UNI. IP clients are perhaps the most important from the
   point of view of the UNI. Hence it is directed at IPO.


JUSTIFICATION

  The UNI signaling work in the OIF has proceeded with the assumption that
  the required extensions in RSVP-TE/LDP will be developed in
  the IETF. This draft serves the role of a liaison document to
  bridge the OIF and the IETF work.
