- Abstract
- Streaming media has contributed to a significant amount of today's Internet Traffic. One solution of to solve this problems is using streaming proxy. There are two categories in streaming proxy; that is for homogeneous and heterogeneous client. The transcoding proxy can be used for heterogeneous client. The traditional proxy considers only a single version of the objects, whether they are to be cached or not. However the transcoding proxy has to evaluate the aggregate effect from caching multiple versions of the same object to determine an optimal set of cache objects. And recent researches about multimedia caching frequently store initial parts of videos on the proxy to reduce playback latency and archive better performance. Also lots of researches manage the contents with segments for efficient storage management. In this paper, we propose the efficient proxy policy that combines the segment-based caching mechanism and aggregate effect at transcoding proxy. The results demonstrate that the proposed algorithm outperforms in delay time, byte-hit ratio and the amount of transcoding data than other methods. © Springer-Verlag Berlin Heidelberg 2007.
