Through analyzing the existing streaming media cache management algorithm and user’s watching behavior characteristics

a new cache prefetching strategy based on selective Markov model was presented.The strategy

by mod-eling the user’s VCR action of choosing the merging sequence method

applied the FP

V

like method to get the selective Markov model FPMM

V

like and built a streaming media proxy cache prefetching mechanism FP

V

like-LRU-2 by com-bining the replacement algorithm LRU-2.The experimental results show that

FP

V

like-LRU-2 is 10%、12%、17% higher than FP

L

RU-2

SP

L

RU-2 and LRU-2 respectively in reducing latency experienced by users

and this value is able to reach over 60% in the ideal situation.
