Hiroaki,
Here a few notes that we had on AAA and Admission Control Framework for
Multicasting (draft-ietf-mboned-multiaaa-framework-10).

1.  Is there a mechanism to prevent the sharing of authorization (e.g.,
sharing an S,G among end users)?

2.  Section 4.1.1 states that "...NSP will forward multicast traffic
towards the user only when the NSP has 1) made sure the user is entitled
to access the network resources operated by the NSP, 2) received a
confirmation from the CP that the user is entitled to access the content
and (possibly) 3) determined that the network resources (e.g.,
bandwidth) are sufficient to deliver the multicast traffic to the user
with the relevant level of quality."  When the third condition is not
satisfied and an end-user is prevented from joining the multicast
stream, should the CP be notified as part of accounting?

3.  The heading to Section 4.1.3 is incorrect.  It should be "A single
CP is connected to multiple NSPs."

4.  On page 19, the reference in the text to Figure 3 should be to
Figure 4.  The text should read:  "In the fully enabled model (Figure 4)
resource management and admission control is provided by MACF (Multicast
Admission Control Function)."

Please let us know if you have questions or if you need additional
details.
Thanks,

Marshall and all,

I submitted the muliticast AAA framework draft.
As I said at IETF75, we just extend the expire date and the cotent is
not changed.
We'd like chairs to check it again as Marshall told at the mboned
meeting.

Thank you
Hiroaki
