On general content delivery networks, replica allocation is effective in reducing propagation delay when users obtain contents. We proposed a content replication algorithm that considers the popularity per file size of content.
On the other hand, delivering large-sized contents causes large transmission delay. Thus, replication algorithms should consider transmission delay to reduce download time for obtaining contents by users.
In this paper, we assume that contents are delivered under reliable transmission control protocols. In this case, round trip time dominates content transmission rate between a server that deliver a requested content and a user that requests the content.
Under this assumption, the effect of proposed method on transmission delay is evaluated, and proposed method provides better performance than a method that preferentially replicates popular and large-sized contents in large-scale simulation conditions. |
