[0040] An information processing system according to a first embodiment of the present invention will be described with reference to the drawings.
[0041] FIG. 1 is a block diagram of the structure of an information processing system according to the present embodiment. In FIG. 1 , an information processing system according to the present embodiment includes an information processing device 1 , a communication processing device 2 and a server device 3 . In FIG. 1 , a case where an information processing device 1 is connected to a communication processing device 2 is described. Alternatively, two or more information processing devices may be connected to the communication processing device 2 . Examples of the information processing apparatus 1 include computers, microwave ovens, telephones, printers, facsimile machines, refrigerators, washing machines, air conditioners, televisions, video recorders, and set-top boxes. The communication processing device 2 and the server devi...

[0082] FIG. 6 is a flowchart showing the processing of step S107 of the flowchart of FIG. 2 in this specific example.
[0083] (Step S301) The request packet transmission control section 14 judges whether or not the response packet receiving section 12 has received a response packet corresponding to the most recently transmitted request packet. That is, it is judged whether a response packet is received in step S103 or whether a timeout occurs in step S105. Then, when the response packet receiving section 12 receives a response packet corresponding to the transmitted request packet, the process proceeds to step S302. When the response packet receiving section 12 has not received a response packet corresponding to the transmitted request packet, the process proceeds to step S303.
[0084] (Step S302) The request packet transmission control section 14 sets the shortest waiting time among the waiting times corresponding to the most recently received response packet and the waiti...

[0104] FIG. 9 is a flowchart showing the processing of step S107 of the flowchart of FIG. 2 in this specific example. In addition, processing other than steps S401 and S402 is the same as the flowchart of FIG. 6 , so description thereof will be omitted.
[0105] (Step S401) The request packet transmission control section 14 judges whether the response packet receiving section 12 cannot receive the transmitted response packet in the past—that is, from when the first request packet was transmitted until the judgment. Next, when there is still a response packet not received by the response packet receiving section 12 up to this point, the process proceeds to step S302. When the response packet receiving section 12 has received all the response packets, the process proceeds to step S402.
[0106] (Step S402) The request packet transmission control section 14 sets a waiting time longer than the waiting time corresponding to the most recently received response packet as the waiting...
