Re: [MBONED] draft-tsou-mboned-multrans-addr-acquisition-01

I believe the subject draft should be adopted as a work item. In 
response to Jacni Qin, I note that the absence of such a document led to 
extensive discussion of the topic in the interim meeting, despite its 
treatment in the problem statement draft. This, I think, is a clear 
indication that something more had to be said.


The question of whether receiver modification is in scope has come up in 
prior discussion. I think there should be a clear statement of the 
following in the introduction to the draft:

(1) The most straightforward solution to the acquisition problem is to 
make receivers dual-stack. That is, the receiver can extract IP 
addresses from the EPG regardless of their version and join and leave 
streams using either IGMP/IPv4 or MLD/IPv6 depending on the supplied 
addresses.

(2) Any solution that involves more costly changes to the receiver than 
making it dual-stack as just defined is therefore probably uneconomic.

This is why the degree of receiver modification required is a 
consideration for the different solution approaches.


One final remark: the current version of the draft doesn't necessarily 
cover all the possibilities, and one would hope the WG might add input 
to make it more inclusive. But it is probably a good start.
