PROBLEM TO BE SOLVED: To reduce traffic necessary for communication between a client and multiple device servers in a device server system in which multiple device servers exist.SOLUTION: In a device server system, when a client transmits data to multiple device servers, data to be transmitted by session type communication as the communication of a conventional device server system are duplicated and transmitted to multiple device servers by multicast communication. Thus, it is possible to more sharply reduce traffic to be consumed as compared with the case where multiple session type communications are used. That is, it is possible to limit necessary traffic to only one session type communication and one multicast communication regardless of the number of device servers. |
