Abstract:
In this paper, we first investigate how a network works when multiple receivers download content simultaneously in content-centric networking (CCN). We are especially interested in the case that the receivers' downloading speeds differ. From our investigation, we show that the download completion time of a faster user degrades excessively due to the problem that there being different downloading speeds decreases the cache-hit rate. To solve this problem, we propose a novel cache management method for simultaneous downloading from multiple receivers for CCN. The concept of the proposed method is to keep cached data packets in a router until they are transferred to the receiver. The proposed method increases the cache-hit rate for a slower receiver, and prevents a slower user from directly downloading data from the content provider. Through computer simulations, we confirm that the proposed method can improve the download completion time performance in the situation that multiple receivers download content at different speeds in CCN.
