A Novel Hybrid Caching Algorithm for Streaming Media Network

Abstract: In this work, a hybrid caching mechanism is implemented to improve the quality of service in online video streaming. Even though, the advancement in multimedia is streaming; the user experience latency during online video streaming. To avoid delay, atunable victimization scheme is used to efficiently allocate the streaming video. The streams are split to minute fragments in order to provide space for number of different streams. The Fragment is that theamount of cached data is adjusted up to finer unit block. Here, both the average arrival time (AAT) and playback rate of the video are defined as hybrid scheme (ATPR). The victim object is selected based on the ATPR value. The lowest ATPRvideo is replaced with requested video. A log is maintained about the details of requested video. Performance evaluation demonstrates that our scheme outperforms other traditional schemes in terms of the different quality-of-service parameters.
