ABSTRACT
This paper studies the streaming of packetized media from mul-
tiple servers to a client over a lossy network. In particular, we
propose a client-driven rate-distortion optimal packet scheduling
algorithm that decides which packet(s) to be requested from which
server(s) at a given request opportunity. In doing so, the proposed
scheduling algorithm not only attains the maximal presentation
quality but also conforms to the rate constraints dictated by the
flow, window and congestion control mechanisms. The simulation
results clearly demonstrate the efficacy of the proposed algorithm
