| Abstract(in English) | On general content delivery networks, replica allocation is effective for reducing propagation delay when users get content. A conventional method which considers popularities per file size has been proposed. However, this method does not take into account the content reallocation when popularity changes due to the passage of time. Therefore, content reallocation with conventional method is expected to generate large traffic because the initial allocation is not considered. In this paper, we propose a novel content reallocation algorithm which considers popularity variation. We also show that this method reduces propagation delay and generated traffic. Results of computer simulation showed that this method provides better performance than the conventional method. |
