Network System, Client and Communication Control Method

摘要

Increasing the processing load on the server is suppressed in a network system in which response requests are intermittently transmitted from a client to a server. A network system has a client configured to transmit response requests at a specific time interval, and a server configured to send a response to the client according to a received response request. The server calculates a communication interval indicating an interval at which the client is to transmit its response request based on a factor affecting the processing load of the server, and sends communication interval information indicating the calculated communication interval to the client. The client transmits its response request at the time interval indicated by the communication interval information received from the server.

1. A network system comprising:
a network; a client coupled to the network and configured to transmit response requests at specific time intervals; and a server coupled to the network, configured to receive the respond requests from the client, and to send a response to the client in response to a received response request; wherein: the server calculates a communication interval indicating a time interval at which the client is to transmit response requests, the communication interval being calculated based on a factor affecting a processing load of the server; the server sends communication interval information indicating the calculated communication interval to the client; and the client uses the calculated communication interval indicated by its received communication interval information as its specific time interval, and transmits its response requests at the calculated communication interval indicated by the its received communication interval information.
