Hi:

The main changes in this version are as follows:

a)  Added Sec 5.4 to discuss some of the issue related to using different forms of delay as congestion indication. Current implementation of NADA relies on absolute one-way delay (OWD), but that's only reliable in controlled environments between senders and receivers with well-synchronized clocks. In this section, we also discuss alternative delay signals NADA can use (relative OWD or RTT), and the pros and cons of each approach.  Thanks to earlier discussions with Pal and Michael W on the mailing list for raising this issue.

b) Fixed various typos in notations in Sec 3 (System Model) so that they now match to the system diagrams and later descriptions in Sec 6 (Sender Behavior). 

c) Slightly revise the text in Sec 8 (Implementation Status) to reflect the fact that we've obtained first set of testbed evaluation results (not too interesting yet, stay tuned ...)

As always, comments are welcome. 

Thanks,
Xiaoqing

Abstract:
   This document describes a scheme named network-assisted dynamic
   adaptation (NADA), a novel congestion control approach for
   interactive real-time media applications, such as video conferencing.
   In the proposed scheme, the sender regulates its sending rate based
   on either implicit or explicit congestion signaling, in a unified
   approach. The scheme can benefit from explicit congestion
   notification (ECN) markings from network nodes. It also maintains
   consistent sender behavior in the absence of such markings, by
   reacting to queuing delays and packet losses instead.

   We present here the overall system architecture, recommended
   behaviors at the sender and the receiver, as well as expected network
   node operations. Results from extensive simulation studies of the
   proposed scheme are available upon request.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
