The DS-Lite solution is based on DS-Lite Basic Bridging BroadBand element (B4) proxying Internet Group Management Protocol (IGMP) and then tunneling IGMP messages over IPv4-in-IPv6 softwire to DS-Lite Address Family Transition Router element (AFTR). IPv4 multicast data received at AFTR is tunneled over IPv4-in-IPv6 softwire to B4 and then delivered to the hosts. This solution integrates well with DS- Lite unicast solution by using IPv4-in-IPv6 softwire and works with unicast IPv6 network connecting B4 with AFTR.}, }
