Method for transferring data to a plurality of modes connected in series by employing an intermediate mode and dividing the system into a plurality of virtual groups

摘要

A method of transferring information to a plurality of offices connected in series in a network includes the following steps. A step (a) is transferring the information from a server office to an intermediate office being substantially intermediate in the plurality of offices. A step (b) is setting the intermediate office which received the information in the step (a) to the server office. A step (c) is virtually dividing the plurality of offices into two groups which respectively include the server offices. And, a step (d) is repeating the steps (a) to (c) for each of the two groups.
