Subject: [Softwires] DS-lite Multicast

Hi WG,

In today meeting, we presented two drafts on to enable multicast in DS-lite. I think they target different use cases:

The use case of http://tools.ietf.org/html/draft-qin-softwire-dslite-multicast-04 is to deliver multicast over DS-lite in an IPv6 multicast enabled network.

The use case of http://tools.ietf.org/html/draft-sarikaya-softwire-dslitemulticast-00 is to deliver multicast over DS-lite in an IPv6 multicast disabled network.

I think both drafts target different use cases. My question to the WG is: Should we work on both use cases? If not, which use case the WG should work on first?

I really want to hear people comments. Please raise your voice in the ML.

Thanks,
/Yiu

Dear Yiu,

>From the perspective of an
operator, we strongly support the first use case. For transmission
efficiency, we need to deliver streaming contents through
multicast-capable network.
And we are doing our effort to make it multicast-capable.

Thanks.

Hi Yiu,all,
 
I see the first use case worth good value to work on, as the reason I
stated during meeting: operators would happy with it because otherwise
(the second case), means moving AFTR lower location, which ends up with
more CAPEX.

Dear all,

I would privilege the first use case, as described in  http://tools.ietf.org/html/draft-qin-softwire-dslite-multicast-04.

Cheers,

Christian.

This is not correct. 
Please take a look at Broadband Forum document WT-242 on IPv6 migration (or read 
my previous mail :-) ).
You can not make one correct from two wrongs.

Dear Behcat,

Can you elaborate it a little more? I don¹t quite follow what makes one
correct from two wrongs. What is the technical argument of this statement?

Thanks,
Yiu

Hi Yiu,

It was a joke.

We need some sense of humor in IETF.

I also support http://tools.ietf.org/html/draft-qin-softwire-dslite-multicast-04

Ah. Ok :-) English isn't my first language. Please bear with me :-p

I think the first use case, delivering multicast over DS-lite in an IPv6
multicast enabled network, is more valuable.
