A server device 20 and a network status notification server device 18 are connected to the Internet 12. The first confirmed network 14 and the second confirmed network 16 are networks for which communication paths have been established, and constitute a part of the Internet 12. Therefore, the proxy server devices 22 and 24 can be accessed from the Internet by IP addresses on the Internet, respectively.

  The transmission unit 2 starts processing for transmitting upload data such as moving image data to the server device 20 via the Internet 12. The proxy server device selection unit 6 detects the start of transmission processing and changes the upload destination to the proxy server device 22 or 24. Which proxy server device 22 or 24 is selected is determined as follows.

  The network status acquisition unit 4 receives the status of the confirmed networks 14 and 16 from the network status notification server device 18. The proxy server device selection means 6 selects, as the upload destination, the proxy server device 22 or 24 connected to the confirmed network 14 or 16 having a margin based on the received status of the confirmed networks 14 and 16.

  When the proxy server device 22 is selected, the upload data is uploaded through the confirmed network 14, and when the proxy server device 24 is selected, the uploaded data is uploaded through the confirmed network 16. Therefore, uploading is performed via a well-defined network.

  Note that when connecting to the Internet from inside a company or the like, a proxy server may be installed between the corporate LAN and the Internet. However, this is for the purpose of prohibiting unauthorized access from the outside by a proxy server, or prohibiting access from a company to a specific Web server via the Internet, or acquiring an access log from the company. .

  In this regard, the use of a proxy server device that has been conventionally known allows a specific route to be selected from a plurality of routes of the network and passed through a network in which more bandwidth is left as in the present invention. It is different from the purpose.

1.4 Upload Processing FIG. 3 shows a flowchart of the upload client program 56 and the upload terminal control program 58.

  By the user's operation, the upload client program 56 starts data upload processing (step S1). The upload terminal control program 58 detects the start of this process (step S11). Therefore, it is preferable that the upload terminal control program 58 is a resident program at least at the part that detects the start of processing.

  Subsequently, under the control of the upload terminal control program 58, the CPU 40 requests the network status notification server device 18 for the status of the first and second confirmed networks 14 and 16 (step S12). The network status notification server device 18 monitors the communication status of the first confirmed network 14 and the second confirmed network 16. In response to the request, the network status notification server device 18 transmits the status of the first and second confirmed networks 14 and 16. For example, the bandwidth of each network and the currently used bandwidth are transmitted as the situation.

  Under the control of the upload terminal control program 58, the CPU 40 receives this (step S13). Further, the CPU 40 selects the proxy server device 22 or 24 connected to the one where the more bandwidth is left among the first and second confirmed networks (step S14).

The upload terminal control program 58 sets the upload / client program 56 so as to upload to the selected proxy server device 22 or 24. Thereby, the upload client program 56 uploads the data to the selected proxy server device 22 or 24 (step S2).

Next, under the control of the upload terminal control program 58, the CPU 40 sets the upload client program 56 so that the two proxy server devices 22 and 24 are the upload destinations (step S19).

In response, the upload client program 56 uploads data to the two proxy server devices 22 and 24 (step S9). In this way, upload processing is simultaneously performed on the two proxy server devices 22 and 24, so that the upload time can be halved.

2.5 Other
(1) In the above embodiment, two proxy server devices are provided. However, it is also possible to provide three or more proxy server devices and perform uploading for these.

(2) In the above-described embodiment, the uploading is performed with respect to the two proxy server devices, such as the first half data and the second half data. However, all the data may be sent to both proxy server devices in an overlapping manner. This is preferable because the number of retransmissions is reduced when the communication line is in a bad state.

(3) In the first embodiment, when a plurality of proxy server devices are selected, the second embodiment may be applied to these two proxy server devices.

(4) In the above embodiment, the network status notification server device 18 is not provided, and the network status acquisition means 4 is not provided correspondingly. However, these may be provided. In this case, the amount of data to be shared with the proxy server device can be determined according to the acquired network status. Thereby, it is possible to perform an appropriate upload according to the network status.
