I'm working on WebRTC services and have found that while developing 
services that forward VP8 video streams if we want to take advantage of 
the VP8 temporal scaling we must get the temporal layer information from 
the RTP header which requires us to decrypt the SRTP packets. This is 
undesirable both because the middle-box needs to have access to the keys 
as well as the because of the added overhead of the decrypt/encrypt 
cycle. This draft proposes an RTP header extension that will allow us to 
use the VP8 temporal layer information included in the header extension 
and therefore do forwarding without SRTP decryption. Comments welcome.

A new version of I-D, draft-fineberg-avtext-temporal-layer-ext-00.txt
has been successfully submitted by Adam Fineberg and posted to the
IETF repository.

Filename:	 draft-fineberg-avtext-temporal-layer-ext
Revision:	 00
Title:		 A Real-Time Transport Protocol (RTP) Header Extension for VP8 Temporal Layer Information
Creation date:	 2013-07-08
Group:		 Individual Submission
Number of pages: 6

    This document defines a mechanism by which packets of Real-Time
    Tranport Protocol (RTP) video streams encoded with the VP8 codec can
    indicate, in an RTP header extension, the temporal layer information
    about the frame encoded in the RTP packet.  This information can be
    used in a middlebox performing bandwidth management of streams
    without requiring it to decrypt the streams.
