For Action

The IETF PWE3 and MPLS WGs are becoming increasingly concerned at the potential impact of the proposed re-engineering of MPLS by ITU SG13 and SG15 to make it more suitable as "a transport network" called "T-MPLS".

Input from network operators indicates that the key requirements is the transparent carriage of the MPLS network of one party over the MPLS network of another party, with the constraint that the MPLS design MUST NOT be changed and that the solution MUST be compatible with their existing large base of already deployed MPLS networks.

Having studied the requirements liaised by SG15 to the IETF
https://datatracker.ietf.org/public/liaison_detail.cgi?detail_id=287

and considered the key issues noted above, the IETF PWE3 and MPLS WGs have formed the view that the essential requirements of operators can be satisfied by existing IETF protocols.

We therefore liaise the following standards track internet draft for your information and would welcome any comments you have on it. It would be useful if your response were available for us to consider at IETF69 which meets on 22 July 2007.

http://www.ietf.org/internet-drafts/draft-ietf-pwe3-mpls-transport-00.txt

On a more general note please can we draw the attention of ITU SG15 to ftp://ftp.rfc-editor.org/in-notes/internet-drafts/draft-andersson-rtg-gmpls-change-08.txt
