Uniform versus priority dropping for layered video

ABSTRACT

In this paper, we analyze the relative merits of uniform versus priority dropping for the transmission of layered video. We first present our original intuitions about these two approaches, and then investigate the issue more thoroughly through simulations and analysis in which we explicitly model the performance of layered video applications. We compare both their performance characteristics and incentive properties, and find that the performance benefit of priority dropping is smaller than we expected, while uniform dropping has worse incentive properties than we previously believed.
