For multicast session/channel announcement, we think some mechanism
should be defined to replace SAP, because SAP has various issues and
easily causes problems or DoS attacks.

We provided "the requirement" draft to design the new session
announcement mechanism or protocol.
http://tools.ietf.org/html/draft-ietf-mboned-session-announcement-req-03

But unfortunately, after it passed WGLC, the chairs decided to stop
the procedure to move it forward. (You can read the mail thread
starting from;
http://www.ietf.org/mail-archive/web/mboned/current/msg01015.html)

On the other hand, we then provided the new I-D, whose direction was
changed from "requirement" to "SAP limitation";
http://tools.ietf.org/html/draft-asaeda-mboned-sap-limitation-00

Since "requirement" seems to imply we will define new protocol/
mechanism for session announcement to replace SAP, and it is the
reason our previous draft could not be finalized, we decided to
clarify the limitation of SAP use first and hence wrote the above
draft.

One more information. In fact, we have been developing a new
multicast channel directory system called Channel Reflector. If you
are interested in it, please take a look at it;

I'm interested in the contribution for multicast service/session
discovery/announcement documentation.
