Summary:In recent computer networks, redundant data are often delivered in a short time in large amount, as represented by a live broadcast. We have developed network nodes with packet caches in order to reduce redundant traffic in TCP/IP network. In our system of nodes, An upstream node converts data into a small identifier and a downstream node reconstructs the original data. We have obtained enough reduction rates experimentally for single redundant contents. In this paper, we propose methods for efficient utilization of the packet cache for reducing multiple redundant contents. We implemented the proposed method to a computer network for our experiments and carried out measurements. We improved efficiency of cache utilization and obtained higher reduction rate with a smaller cache.
