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.
