Abstract:
Dual-Stack Lite (RFC 6333) describes an architecture for transporting
IPv4 packets over an IPv6 network. This document specifies an
extension to DS-Lite called Lightweight 4over6 which moves the
Network Address and Port Translation (NAPT) function from the
centralized DS-Lite tunnel concentrator to the tunnel client located
in the Customer Premises Equipment (CPE). This removes the
requirement for a Carrier Grade NAT function in the tunnel
concentrator and reduces the amount of centralized state that must be
held to a per-subscriber level. In order to delegate the NAPT
function and make IPv4 Address sharing possible, port-restricted IPv4
addresses are allocated to the CPEs.
