- Abstract
- In this paper, we present a new cache management method,
named Sliding Window Caching Policy to efficiently store the videos
in a proxy server. The proxy server periodically measures time popularity
(TP) and requested video segments from users. Based on these measured data,
the proxy server calculates the average time popularity and average
request segment of a video utilizing Sliding Window.
Then, we estimate the priority of replacement when the
cache is running out of space and the maximum size of storage space
to be allocated to a video. In addition, we propose a conditional
active prefetching in order to provide a continuous streaming delivery to clients.
The simulation results show that the proposed algorithm performs better than other
algorithm such as LRU, LFU, TP, Pyramid, and Prefix methods in terms of packet hit
rate and number of replacement in random access pattern and Zipf distribution
access Pattern.
