Distributing Layered Encoded Video Through Caches
The efficient distribution of stored information has become a major concern in the Internet which has increasingly become a vehicle for the transport of stored video. Because of the highly heterogeneous access to the Internet, researchers and engineers have argued for layered encoded video. In this paper the authors investigate delivering layered encoded video using caches. Based on a stochastic knapsack model they develop a model for the layered video caching problem. They propose heuristics to determine which videos and which layers in the videos should be cached.
