Re: [MBONED] Last Call: <draft-ietf-mboned-interdomain-peering-bcp-10.txt> (Use of Multicast Across Inter-Domain Peering Points) to Best Current Practice

["TARAPORE, PERCY S" <[e-mail]>]

Hi Luis,

Thanks for your comment on this BCP. We discussed the possibility of adding a new Use Case for a transit provider AD-3. We felt that adding this Use Case would require significant changes in the Section 4 Functional Guidelines. For that purpose, we have added a short paragraph towards the end of Section 1 "Introduction" stating that the possibility of a transit situation exists and that additional complexities would arise. We indicate therefore that this Use Case is out of scope and for further study. The new version of the draft stating this has been uploaded.

Thanks so much for your useful comment.

Best wishes,

Percy

Dear all,

I have a specific comment regarding to this document. It states (third bullet in page 5) that the multicast traffic to be inter-exchanged via the peering point is the one generated locally, in this case by AD-1 ("a service provider controls one or more application sources in AD-1 ..."). 
So it does not consider the situation where one carrier may act as
(multicast) transit provider. In other words, a scenario where AD-3 could obtain via AD-2 the multicast traffic generated by AD-1.

Maybe I’m wrong, but in my understanding the scenarios and methods described in the draft could permit such transit scenario, but no statement is done to clarify if it is feasible or not. It can be interesting to clarify this point in the final version of the document.

Thanks

Luis M. Contreras
