This memo documents a multicast CDN (Content Delivery Network) issues,
and describes requirement and discussion points when we solve them.
Here, we need a method of precise user accounting (logging) of a user
activity to a multicast group and of user access control to a
multicast group to protect to subscribe from an illegal access. In
this case, it is needed to authorize a user access to a multicast
group on the CDN, and to get information of user action (Join/Leave)
to a multicast group. The key is how a control process of group
membership synchronizes with an AAA process (authentication,
authorization and accounting), because we can get a user access
information at an AAA server. This depends on the network model of
the multicast CDN service. Last of all, we introduce an example of
solution MLDA (Multicast Listener Discovery Authentication protocol).

In the body type:
"FILE /internet-drafts/draft-hayashi-mlda-02.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
