PROBLEM TO BE SOLVED: To provide a device server capable of eliminating any influence accompanied by the undulation of a data transfer amount due to the delay of a network in isochronous output transfer in a device server to which a device is locally connected, and maintaining the data transfer amount to be guaranteed in isochronous transfer, and improving the network durability of the isochronous output transfer.SOLUTION: A device server includes a data buffer part for buffering isochronous output transfer data. The device server is configured to, when receiving an isochronous output transfer request from a client, instantaneously and unconditionally return a transfer completion response to the client, and to perform look-ahead of the isochronous output transfer data, and to store the received transfer data in the data buffer part, and to, when the held data amount of the data buffer part reaches an upper limit threshold, start the isochronous output transfer to the device at a predetermined transfer rate about the transfer data buffered in the data buffer part. |
