abstract:
The current caching strategies mainly concern about the performance CCN from the user perspective, without considering the problem of transmission cost when the network provides service for users. To overcome this problem, a caching strategy is proposed for minimization of the transmission cost of CCN. First, a method is presented to calculate the cache value of content, and use the cache value to measure the effect of cache on the network transmission cost. Then, the cache decision and cache replacement strategies for minimizing the transmission cost are represented based on the cache value of content. Finally, simulation experiment based on ndnSIM demonstrates that compared with existing strategies, the proposed strategy can significantly decrease the network transmission cost.
