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 maintain a subscriber side 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.
