Improving Performance for Multimedia Traffic With Distributed Dynamic QoS Adaptation

In this paper, the authors describe and present results of using an architecture that leverages the potential of IETF's Differentiated Services giving the border of the network the necessary knowledge to better react to core conditions when impairment is foreseen for important traffic such as video streaming, using limited signalization. The architecture is named Distributed Dynamic Quality of Service - DDQoS - and includes models for both the core and the edge of the network. A video quality assessment framework is developed, allowing standard industry metrics like VQM to be used for estimating quality of experience.
