PROBLEM TO BE SOLVED: To suppress a load on a server side from increasing even when the number of connections of client terminals increases.SOLUTION: An integrated server 3 comprises: an information gathering part which gathers facility information from servers 2 by systems at a fixed period and outputs the information to a holding part 4; a request receiving part 32 which receives a request for facility information from a client terminal 5; an information acquiring part 33 which extracts corresponding facility information from the holding part 4 and sets the time obtained by adding a predetermined time to next gathering time as next request time when a request is received; and an information transmission part 34 which sends the obtained facility information and information indicative of the request time to the client terminal 5. The client terminal 5 comprises an information requesting part 51 which requests facility information to the integrated server 3 and an information receiving part 52 which receives the facility information and the information indicative of the request time from the integrated server 3, and the information request part 51 makes a request at the request time when the information indicative of the request time is received.SELECTED DRAWING: Figure 1 |
