ABSTRACT:
In a data transfer system in which when a first to fourth terminals require reading data, the data are read out of a first to fourth storages to be stored in a first and second buffer memories while a first and second virtual groups of storages are alternately switched every constant cycle, and thereafter a first and second data sending units send the data stored in the first and second buffer memories to the terminals; on the other hand, when the first to fourth terminals require writing data, received data is divided in a way to distribute the process loads of data read and data write of the divided data equally into a first and second data transfer units. At the same time, the data are stored in the first and second buffer memories of the first and second data transfer units, and thereafter the data are written into the first to fourth storages while switching the first and second virtual groups of storages alternately. As a result, the load of transferring data to the terminals is not concentrated on a particular data transfer unit in the data transfer system, even when the rate of request-to-reads from the terminals changes or differs from those of others.
