Hi MOPS,

I would like to make this group aware of the following document. 

The draft introduces a use case that a packet's importance may differ due to the scalability property of media codecs. The draft discusses a new set of complementary requirements for application and network to further improve QoE of end users, when dealing with network congestion.   

Look forward to discussion and feedback.

On behalf of the authors,

Best Regards
Lijun Dong

Abstract:
   This document introduces a use case of packets' significance
   difference embedded with media scalability.  With the dominance of
   video traffic on the Internet, selectively dropping packets or parts
   of packets from competing media streams becomes a complementary
   mechanism when dealing with network congestion.

   The document describes the characteristics of media scalability, some
   limitations of existing end-to-end congestion control mechanisms
   through rate control and adaptation, explains why current ways of
   entire packet dropping at the traffic class level using in-network
   active queue management are not most appropriate to meet end users'
   Quality of Service expectations.  The document identifies that there
   exists "significance difference" among packets or even among parts of
   the packets within a flow, and brings out a new set of requirements
   for application and network to support packet significance difference
   to improve the Quality of Experience of end users.
