Abstract
With respect to a data transfer over a network, data is stored in each cache of the network and the retrieving processing following the second retrieving processing is executed by using a cache, thereby resulting in a transfer amount being decreased. Statistics information of a data transfer over the network is obtained. When transfer data is stored in a low-speed storage such as a disk, only data of high access frequency is stored and data of low access frequency is discarded, thereby solving such a problem that a speed of a disk apparatus becomes a bottleneck.
