(operation)
The operation of above-mentioned information processing system 1 is described below.First, as shown in Figure 4, first user terminal UA1 will include For identifying that the connection request notification transmission of the identification information of the second user terminal UA2 (or relay function portion 112) is to management Member's function part 110 (step S101).
Therefore, manager function portion 110 receives connection request notice.Then, manager function portion 110 is in order to connect control Portion 111 performs mode of operation and determines process (step S102).Describe mode of operation referring to Fig. 5 and determine process.
As it is shown in figure 5, first, manager function portion 110 obtains the load (step S111) connecting control portion 111.Subsequently, Determine that whether the load of acquisition is more than presetting load threshold (connect and control load threshold) (step S112).
When determining load no more than load threshold (step S112: no), manager function portion 110 obtains and is connecting control Whether portion 111 occurs in that fault (detection fault) (step S113).When determining the appearance (step S114: yes) of fault, and When load being defined as more than load threshold (step S112: yes), manager function portion 110 instructs another information process unit Control the connection (step S115) between multiple user terminal.After the process of step S115, mode of operation determines that process is eventually Only, the process of Fig. 4 and is re-executed by another information process unit (such as, the second information process unit 20).
It is to say, information process unit (such as, the second information process unit 20) is from another information process unit (example As, first information processing unit 10) receive connection request notice rather than receive connection request notice (step from user terminal S101), then, step S102 and process afterwards are performed.Note, when there being multiple information process unit, manager function Connection request notice is such as transmitted to the information process unit with minimum load in portion 110.Therefore, connect from information process unit 10 Another information process unit receiving connection request notice can determine process with skip operations state.
On the other hand, when determining that fault occurs without (step S114: no), process step S103 proceeding to Fig. 4.The most just It is to say, determines the result of process as the mode of operation of step S102, if connecting the load in control portion 111 for presetting load threshold Value or less, and connect in control portion 111 and do not break down, then manager function portion 110 will connection request notify in wrap The identification information included has been transferred to stateful proxy function part 120 (step S103).

Therefore, stateful proxy function part 120 is had to receive communications destination IP address.Then, there is stateful proxy function part 120 Communications destination IP address is transferred to first user terminal UA1 (step S106).Therefore, user terminal UA1 receives communication mesh IP address, ground.Note, when receiving the connection request notice from another information process unit, having stateful proxy function part Communications destination IP address is transferred in the process of step S106 receive from it at another information of connection request notice by 120 Reason unit.Then, (biography is transmitted in communications destination IP address by another information process unit receiving communications destination IP address Send) to user terminal.
Then, as shown in Figure 6, server connection request is transferred to manage logical by receive by first user terminal UA1 The manager function portion 110 (step S121) in the relay function portion 112 that letter destination IP address is specified.Therefore, manager function Portion 110 receives server connection request.Then, manager function portion 110 determines in order to relay function portion 112 performs mode of operation Process (step S122).It is to say, manager function portion 110 performs and the process phase described in Fig. 5 for relay function portion 112 Same process.
Mode of operation as step S122 determines the result of process, when the load of relaying function part 112 is predetermined threshold value Or less, and when not breaking down in relaying function part 112, manager function portion 110 is by server connection request Including communications destination IP address and (the communication source IP ground, IP address of first user terminal UA1 (communication source user terminal) Location) it is transferred to relay function portion 112 (step S123).
Therefore, relay function portion 112 receives IP address (communication source IP address and communications destination IP address).Then, in The function part 112 that continues is connected (step S124) based on the IP address received with user terminal.
Note, determine the result of process as the mode of operation of step S122, if the load in relay function portion 112 is more than Predetermined threshold value or occurred in that fault in relay function portion 112, then manager function portion 110 detection and information processing list The information process units that unit 10 has a beeline, and instruct this information process unit (or including relay function portion 112) communication between multiple user terminal is relayed.Therefore, it can reduce the delay being associated with trunking traffic.
Then, it is commanded another information process unit multiple users of relaying of trunking traffic eventually by information process unit Communication between end.During this period, the session between information process unit and another information process unit is kept.Therefore, when During user terminal access information process unit, this user terminal is automatically communicated out of Memory processing unit.Therefore, even if working as When occurring congested etc. in information process unit, the user of operation user terminal can also transmit with other user terminals safely Information, it is not necessary to perform predetermined operation.
Therefore, when the operation within information process unit 10 is normal, information process unit 10 is held with multiple user terminals The predetermined communication process of row (such as, as shown in Fig. 7 (1)).But, when the load of information process unit 10 increases, or Person when information process unit 10 breaks down, cause in the communication between multiple user terminals possible congested time, information Processing unit 10 instructs another information process unit and processes communication (such as, as shown in Fig. 7 (2)), and switches execution mailing address The information process unit of reason.Then, another information process unit is held between multiple user terminals via information process unit The predetermined communication process of row (such as, as shown in Fig. 7 (3)).Therefore, it can transmit safely between multiple user terminals Predetermined information.
Additionally, user terminal can be connected with other information process units global via information process unit.Therefore, Even if in disaster or certain region in the case of the paralysis of information process unit function, it is also ensured that between user terminal Communication, will not cause congested.
