- Abstract
- In this paper, we present a cache
management policy to efficiently store the videos in a proxy
server. The objective of cache management policy is to
maximize the quality of service (QoS) to interested clients by
improving the hit rate of popular videos. Our cache
management policy is based on capturing the changing
preference of the videos according to recentness, frequency,
and playback length of the requested videos. For this
purpose, we define a parameter, access time, which
represents the total playback time of video within a
predefined interval. We also utilize the time popularity (TP)
that denotes the number of client access to the each video
within a predefined interval. Using the access time and TP,
we can estimate a maximum available space of a video
which means the maximum size of storage space to be
allocated to the video. Our simulation results show that the
hit rate of the proposed method is greater than the previous
works. The simulation results show that the proposed
algorithm performs better than other algorithm such as
LRU, LFU, and TP methods in terms of packet hit rate in
random access pattern and Zipf distribution access
Pattern.
