The IESG has approved the following document: - 'CGN Deployment with BGP/MPLS IP VPNs' (draft-ietf-opsawg-lsn-deployment-06.txt) as Informational RFC This document is the product of the Operations and Management Area Working Group. The IESG contact persons are Benoit Claise and Joel Jaeggli. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-opsawg-lsn-deployment/ Technical Summary This document specifies a framework to integrate a Network Address Translation layer into an operator's network to function as a Carrier Grade NAT (also known as CGN or Large Scale NAT). The CGN infrastructure will often form a NAT444 environment as the subscriber home network will likely also maintain a subscriber side NAT function. The model included in this document utilizes BGP/MPLS IP VPNs which allow for virtual routing separation helping ease the CGNs impact on the network. This document does not intend to defend the merits of CGN. Working Group Summary While there was clear support for the document within the opsawg, there was little discussion and no comments during working group last call. However, the authors were quite proactive about getting feedback from operators outside the working group context, and having that feedback posted to the working group mailing list, so we feel that the document received satisfactory expert review prior to and during last call. (This was discussed with the OPS ADs after closing working group last call). Document Quality This is a well-written document that clearly lays out the background, requirements, and deployment scenarios using straightforward, unambiguous language. It received expert review from cable and telecomm operators during its development, and the authors are employed by Rogers Communication, a large Canadian telecomm firm. Personnel Melinda Shore is the document shepherd. Benoit Claise is the responsible area director
