Uniform versus priority dropping for layered video

Sandeep Bajaj, Lee Breslau, Scott Shenker
1998 Computer communication review  
In this paper, we analyze the relative merits of uniform versus priority dropping for the transmission of layered video.  ...  We compare both their performance charact,eristics and incentive properties, and find that the performance benefit of priority dropping is smaller than we expected, while uniform dropping has worse incentive  ...  To address the relative performance of uniform versus priority dropping, we first c,onsider a single flow.  ...
