Problems solved by technology

[0012] However, in such a system, if the number of services provided by the server increases and / or when the number of clients increases, the amount of data to be transmitted using polling communication (amount of inquiry data) increases, thereby increasing network communication quantity
Further, due to the increase in client access, there may be a considerable load on the server
