Effective caching algorithm by minimizing normalized buffer size over constant bit rate channel

Abstract

In this work, we present an effective caching algorithm of proxy server with the finite storage size. Under the general video traffic condition, it is observed that the reduced amount of receiver buffer size and channel bandwidth depends on both the frame size and the frame position. To consider this fact, we propose an effective caching algorithm to select the positions of cached frames based on the normalized buffer size. Finally, experimental results are provided to show the superior performance of the proposed algorithm.
