Subject: [AVT] Sound level indicators

Hi all,

I've just submitted the following draft:

http://www.ietf.org/internet-drafts/draft-lennox-avt-rtp-audio-level-ext
hdr-00.txt

The draft addresses a similar, though not identical, issue, to
draft-ivov-avt-slic-00.

It defines an RTP extension header which indicates the audio level, and
voice activity detection state, of a packet's RTP audio payload.  In
large conferences, this can reduce the load on an audio mixer or other
middlebox which wants to forward only a few of the loudest audio
streams, without requiring it to decode and measure every stream it's
receiving.

Comments are welcome!
