Cost-distortion optimized streaming media over DiffServ networks

In this paper, we address the problem of multimedia streaming

over DiffServ networks that offer various qualities of service (QoS)

at different price points. In particular, we seek cost-distortion optimized

transmission policies that minimize the distortion seen by

the client under a cost constraint. Our results show that for ondemand

streaming of stored media, DiffServ networks provide little

or no gain over networks that offers only a single, cost-effective,

QoS. However, for real-time conversational communication or multicast

streaming, optimized transmission over DiffServ networks

can perform better than optimized transmission over any single

QoS by over 2 dB at the same cost.
