Abstract

One aspect of the present invention is an information processing system including a computing machine installed in a computing machine base, a first transmission/reception device connected to the computing machine, a second transmission/reception device installed in a user base used by a user, a device connected to the second transmission/reception device, and a delay control device configured to measure a delay amount generated between the first transmission/reception device and the second transmission/reception device and control the measured delay amount.

Claims (24)

1 . An information processing system comprising:

a computing machine installed in a computing machine base;

a first transmission/reception device connected to the computing machine;

a second transmission/reception device installed in a user base used by a user;

a network configured to connect the first transmission/reception device and the second transmission/reception device;

a device connected to the second transmission/reception device; and

a delay control device configured to measure a delay amount generated between the first transmission/reception device and the second transmission/reception device and control the measured delay amount,

wherein the device is connected to the computing machine via the network.

2 . The information processing system according to claim 1 , wherein,

in a case where there are a plurality of connections between the first transmission/reception device and the second transmission/reception device, the delay control device is configured to measure a delay amount of each of the plurality of connections, and to adjust at least one of the plurality of delay amounts to adjust the plurality of delay amounts to a same amount.

3 . The information processing system according to claim 1 , wherein

the delay control device is configured to adjust the delay amount without interrupting a signal between the first transmission/reception device and the second transmission/reception device when the delay amount is adjusted.

4 . The information processing system according to claim 1 , wherein

a signal between the first transmission/reception device and the second transmission/reception device is encrypted.

5 . The information processing system according to claim 1 , wherein,

in a case where there are a plurality of connections between the first transmission/reception device and the second transmission/reception device, the delay control device is configured to detect an increase or decrease in the number of users, and to readjust the delay amount according to the increase or decrease in the number of users.

6 . A delay control device

configured to measure a delay amount generated between a first transmission/reception device that is connected to a computing machine installed in a computing machine base and a second transmission/reception device that is installed in a user base used by a user and to which a device used by the user is connected, and to control the measured delay amount, wherein the device is connected to the computing machine via a network configured to connect the first transmission/reception device and the second transmission/reception device.

7 . An information processing method in an information processing system comprising a computing machine installed in a computing machine base, a first transmission/reception device connected to the computing machine, a second transmission/reception device installed in a user base used by a user, a network configured to connect the first transmission/reception device and the second transmission/reception device, a device connected to the second transmission/reception device, and a delay control device, the device being connected to the computing machine via the network, the information processing method comprising

measuring, by the delay control device, a delay amount generated between the first transmission/reception device and the second transmission/reception device, and controlling the measured delay amount.

8 . A non-transitory computer readable storage medium storing a program for causing a computer of a delay control device in an information processing system, which comprises a computing machine installed in a computing machine base, a first transmission/reception device connected to the computing machine, a second transmission/reception device installed in a user base used by a user, a network configured to connect the first transmission/reception device and the second transmission/reception device, a device connected to the second transmission/reception device, and the delay control device, the device being connected to the computing machine via the network, to execute

measuring a delay amount generated between the first transmission/reception device and the second transmission/reception device, and controlling the measured delay amount.

9 . The information processing system according to claim 1 , wherein,

the network is a circuit switched network or a packet switched network.
