Abstract:
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 contain a NAT function. Exhaustion of
the IPv4 address pool is a major driver compelling some operators to
implement CGN. Although operators may wish to deploy IPv6 to
strategically overcome IPv4 exhaustion, near term needs may not be
satisfied with an IPv6 deployment alone. This document provides a
practical integration model which allows the CGN platform to be
integrated into the network meeting the connectivity needs of the
subscriber while being mindful of not disrupting existing services
and meeting the technical challenges that CGN brings. 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.
