Hi,

We submitted the updated version of the NADA scheme, as presented by Rong on Monday.

The major change from the last version is that all forms of congestion signals from the network (loss/delay/ECN/PCN) are now integrated into a composite signal (which we call "equivalent delay"), so that the sender can react in exactly the same manner. No more mode switching between ECN-enabled and ECN-disabled at the sender, as in draft-00 and criticized by Michael in previous email discussions.

We also much appreciate all the feedback and discussions on the scheme during the WG meeting on Monday, as summarized in Spencer's notes. Will try to address these issues, clarify some of the doubts, and improve our design accordingly.

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.
