1. An information processing system comprising:
a computer installed in a computer base and a first transceiver connected to the computer;
a second transceiver installed in a user base used by a user and a device connected to the second transceiver;
a network configured to perform communication between a plurality of the first transceivers and the second transceiver; and
a controller configured to control connection between one of the plurality of the first transceivers and the second transceiver,
wherein the controller is configured to control connection between one of the plurality of the first transceivers and the second transceiver via the network having a circuit switching function,
wherein
each of the plurality of the first transceivers comprises a first delay measurement unit configured to measure delay time between the first transceiver and the second transceiver,
the second transceiver comprises a second delay measurement unit configured to measure delay time between the first transceiver and the second transceiver, and
the controller is configured to:
acquire the delay time from at least one of the second transceiver or the plurality of the first transceivers; and
determine, as a target to be connected to the second transceiver, the one of the plurality of the first transceivers on a basis of the delay time and predetermined round-trip time, round-trip time between the one of the plurality of the first transceivers and the second transceiver being within the predetermined round-trip time.
