Title : Lightweight 4over6: An Extension to the DS-Lite Architecture Authors : Yong Cui Qiong Sun Mohamed Boucadair Tina Tsou Yiu L. Lee Ian Farrer Filename : draft-ietf-softwire-lw4over6-11.txt Pages : 21 Date : 2014-10-15 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.
