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.}, }
