I don¹t understand his point. Let¹s put the 1:1 aside, MAP-E requires IPv4
rule to algorithmically build the CE IPv6 prefix. In lw4o6 Section 5.1, we
simple put the v4 in the IID. Isn¹t it obviously there is no v4/v6
dependency? What Woj tries to argue? I lost. Can somebody explain to me

Hi Stig,
DS-Lite was designed to deliver v4 unicast packets over v6-only network to
v4 host. However when we started thinking about how to deliver multicast
packets in the same network setup, we will have to tunnel all multicast
packets over tunnels. This is very inefficient to use of AFTR. This

Ah. Thanks for the heads-up . This also happened to dslite. It was

Hi Tina,
To use PMTU in this scenario, this is more complicated than what you explain.
First, this traffic flow is from mAFTR to the mB4. In between, there could be
more than one IPv6 multicast routers. In our spec, mAFTR will replicate the
packet once in the multicast I/F to the IPv6 MDT, can
Hi Tina,
Sure can but IPv6 MTU discovery like IPv4 MTU discovery, it is unreliable.
We can list it as an option but readers should notice this may not work in
all cases.

Hi Tina,
What do you see new here in this scenario? mAFTR is a logical function, it
would perform MLD PIMv4-Join interworking. This has been captured. If a vendor
wants to make mAFTR also a L2 device, it would perform standard MLD snooping.
What else is missing?

I also agree this is a very nice piece of work. The current title is
Implementing AplusP in the provider's IPv6-only network. I think this
not only covers Implementing AplusP in an IPv6-only network, but also
captures very important information about the port usage in various
applications. I would
Hi Satoru,
I think you answered your question. As you said, it is possible to use 1
port (in theory) to reach 2000 sessions as long as each destination is
different. So given user 256 ports could create a much larger set of NAT
sessions in the CGN.

Hi Qiong,
I see your point. So what is the difference between a lightweight AFTR and 4rd
BR?

If I understand it correctly, a per user address/port mapping table is
maintained on the LW AFTR, then no session table on it.

Couple thoughts.
1. The current draft doesn't specify the static mapping rule like what 4rd
does. So I guess we can't compare this to 4rd.
2. I keep thinking what are the difference of this and PRR. I guess
Qiong's PRR definition is the forwarding decision would be done in the

You are right. The current 'draft-cui-softwire-host-4over6' describes how
a server is provisioned a public IPv4 address over an IPv6-only network.
IPv4 address sharing wasn't discussed in the draft.

In their tests, bittorrent seems use most ports (200). Other public apps
