Description

Response wait time update device, system, method, and recording medium

The present invention relates to a response waiting time updating apparatus, system, method, and recording medium for updating a communication response waiting time according to a communication response time.

In a general CPE (Customer Premises Equipment) system, a DHCP (Dynamic Host Configuration Protocol) function, a NAT (Network Address Translation) function, and the like are implemented in the CPE. In the case of this configuration, when the user performs setting such as DHCP of the CPE, the CPE can change its own setting without communicating with other devices.

In contrast, a vCPE (virtualized CPE) system has a DHCP function and a NAT function on the network side of a telecommunications carrier. Moreover, it can be set as the structure which provides each of these functions with a respectively separate server.

Communicating between servers when each function is provided by different servers. In addition, network delays may occur in communication between servers, and processing delays may occur due to server congestion due to network congestion or system switching between geographically distant servers. . If a network delay or a processing delay occurs and the communication times out without returning even if the communication response between the servers exceeds the waiting time during the CPE setting, the CPE setting is not completed and each function of the CPE May not be available.

On the other hand, when a network delay or processing delay occurs, the communication response time between servers becomes longer. The communication response time between apparatuses can be measured by the method described in Patent Document 1 or Patent Document 2, for example.

However, in the methods described in Patent Document 1 and Patent Document 2, the communication response time can be measured. However, since the waiting time for the communication response is fixed, a communication timeout occurs when the communication response time exceeds the waiting time. appear.

An object of the present invention is to provide a response waiting time update apparatus, system, method, and recording medium that can reduce the frequency of communication timeout due to a delay in communication response.

In order to solve the above-described problem, the response waiting time update device according to the present invention has a value that monotonously increases according to the communication response time between the first communication device and the second communication device. Waiting time updating means for updating the waiting time of the first communication device with respect to a communication response from the communication device is provided.

Further, the response waiting time update method of the present invention provides a value that monotonously increases in accordance with the communication response time between the first communication device and the second communication device, with respect to the communication response from the second communication device. The waiting time of the first communication device is updated.

The response waiting time update program recorded on the computer-readable recording medium of the present invention is a value that monotonically increases in response to the communication response time between the first communication device and the second communication device. Further, a waiting time update function for updating a waiting time of the first communication device with respect to a communication response from the second communication device is realized.

[First embodiment]
A first embodiment of the present invention will be described.

FIG. 1 shows a configuration example of the response waiting time update device 10 of the present embodiment. The response waiting time update device 10 of the present embodiment includes a waiting time update unit 11.

The waiting time update unit 11 has a value that monotonously increases according to the communication response time between the first communication device and the second communication device, and the first communication device responds to the communication response from the second communication device. This is the part that updates the waiting time.

By configuring the response wait time update device 10 in this way, the response wait time update device 10 has a value that monotonously increases according to the communication response time between the first communication device and the second communication device. The waiting time of the first communication device for the communication response from the second communication device is updated. Thereby, when the delay of the communication response increases, the waiting time of the first communication device can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

Next, FIG. 2 shows an example of the operation of the response waiting time update device 10 of the present embodiment.

The waiting time update unit 11 has a value that monotonously increases according to the communication response time between the first communication device and the second communication device, and the first communication device responds to the communication response from the second communication device. The waiting time is updated (step S101).

By operating in this way, the response waiting time update device 10 has a value that increases monotonically according to the communication response time between the first communication device and the second communication device, from the second communication device. The waiting time of the first communication device for the communication response is updated. Thereby, when the delay of the communication response increases, the waiting time of the first communication device can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

As described above, in the first embodiment of the present invention, the response waiting time update device 10 is a value that monotonously increases according to the communication response time between the first communication device and the second communication device. In addition, the waiting time of the first communication device for the communication response from the second communication device is updated. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In this embodiment, the response waiting time update device of the first embodiment will be described more specifically.

First, FIG. 3 shows a configuration example of the vCPE system 71 using the response waiting time update device of the present embodiment. The vCPE system 71 of this embodiment includes a NAT function, a DHCP function, a Portal function, and an O & M (Operation and Maintenance) function. Each function may be deployed on an individual server, or a plurality of functions may be deployed on the same server.

In this embodiment, it is assumed that each function is deployed on a separate server. A server that provides the NAT function is a NAT server 72, a server that provides the DHCP function is a DHCP server 73, a server that provides the Portal function is a Portal server 74, and a server that provides the O & M function is an O & M server 75.

When the system user sets the CPE 70, the system user first accesses the Portal site provided by the Portal server 74, and sets DHCP or the like on the site. The O & M server 75 also monitors the status of each server and manages statistical information. At that time, inter-device communication occurs between the Portal server 74 and the DHCP server 73, between the Portal server 74 and the NAT server 72, and between the O & M server 75 and each server.

Next, FIG. 4 shows a configuration example of the response waiting time update device 20 of the present embodiment. The response waiting time update device 20 of this embodiment corresponds to the NAT server 72, DHCP server 73, Portal server 74, or O & M server 75 of FIG. The response waiting time update device 20 of the present embodiment corresponds to the “first communication device” in the first embodiment.

The response waiting time update device 20 includes a waiting time update unit 11 and a response time measurement unit 22.

The response time measuring unit 22 is a part that measures the communication response time between the response waiting time update device 20 (first communication device) and the second communication device 60 at predetermined time intervals. The second communication device 60 corresponds to a communication partner server.

The waiting time update unit 11 sets the response waiting time update device 20 (first communication device) for the communication response from the second communication device 60 to a value that monotonously increases according to the communication response time measured by the response time measurement unit 22. ) Is a part for updating the waiting time.

By configuring the response wait time update device 20 in this way, the response wait time update device 20 is a value that monotonously increases according to the communication response time between the response wait time update device 20 and the second communication device 60. Next, the waiting time of the response waiting time update device 20 for the communication response from the second communication device 60 is updated. Thereby, when the delay of the communication response increases, the waiting time of the response waiting time update device 20 can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

Also, since it becomes possible to reduce the frequency of communication timeout, it becomes possible to reduce setting failure due to communication timeout when setting CPE.

In addition, since it is possible to automatically update the waiting time for the communication response, it is possible to suppress OPEX (Operating Expense) and reduce the possibility of an operation error compared with the case where the waiting time is adjusted manually. It becomes possible.

Also, as another method for preventing communication between servers from timing out, it is conceivable to always fix the waiting time for communication response of each server to a large value. However, in a situation in which communication between servers fails due to congestion or network failure, if the communication response waiting time is too long, the CPE user is more than necessary when setting the CPE or accessing the network. I will be waiting. Therefore, it is desirable that the communication response waiting time be as small as possible.

On the other hand, the response waiting time update device 20 of the present embodiment reduces the waiting time of the response waiting time update device 20 for the communication response from the second communication device 60 when the communication response time becomes shorter. Therefore, it is possible to reduce the user's response waiting time in a situation where a timeout occurs due to a failure or the like.

Next, FIG. 5 shows an operation example of the response waiting time update device 20 of the present embodiment.

First, the response time measuring unit 22 measures the communication response time between the response waiting time update device 20 and the second communication device 60 every predetermined time (for example, every 5 seconds) (step S201). When the communication response time measured by the response time measurement unit 22 changes (YES in step S202), the wait time update unit 11 waits for the response wait time update device 20 for the communication response from the second communication device 60. The time is updated (step S203).

The communication response time is measured, for example, by transmitting a measurement packet from the response wait time update device 20 to the second communication device 60 and receiving a response packet from the second communication device 60 for the measurement packet. You can get it. A plurality of measurement packets may be transmitted and the average value, median value, mode value, etc. may be used.

For the change judgment, the change rate or difference from the communication response time up to that point can be used. When the communication response time measured for the first time after the update of the waiting time is T_1 and the communication response time measured for the nth time is T_n, the rate of change can be calculated by, for example, | T_n−T_1 | / T_1. When the rate of change is equal to or greater than a predetermined rate (for example, 50%), it is determined that the communication response time has changed. Similarly, the difference in communication response time can be calculated by | T_n−T_1 |. When this difference is a predetermined value (for example, 50 ms) or more, it is determined that the communication response time has changed.

Note that different criteria may be applied to cases where the communication response time increases and decreases. For example, when the communication response time increases, the difference may be determined to be changed when the difference is equal to or greater than a predetermined value, and when the difference is decreased, it may be determined that the change has occurred when the rate of change is equal to or greater than the predetermined rate.

Further, as a target to be compared with the latest communication response time, the communication response time of the previous measurement, the average value, the median value, or the mode value of the communication response time within a predetermined period may be used.

In order to avoid frequently updating the communication response waiting time, it is possible to update the waiting time when a change in communication response time continues for a predetermined number of times or more, as in the example of FIG.

First, the waiting time update unit 11 initializes the number of continuations of change to 0 (step S301). Then, the response time measuring unit 22 measures the communication response time (step S302). The waiting time updating unit 11 determines whether or not the communication response time has changed using the rate or difference of the change in the communication response time, and when the communication response time has changed (YES in step S303), the change is continued. 1 is added to the number of times (step S304). When the number of continuations of the change is equal to or greater than the predetermined number (YES in step S305), the waiting time of the response waiting time update device 20 for the communication response from the second communication device 60 is updated (step S306). When there is no change in the communication response time (NO in step S303) and when the waiting time is updated (step S306), the number of continuations of the change is initialized to 0 (step S301).

When judging the change in communication response time, it is desirable not to change the object to be compared with the latest communication response time while counting up the number of continuations of the change. If the comparison target changes, the change cannot be detected when the communication response time changes gradually. Therefore, for example, a method of storing a comparison target when the number of continuations of change is 0 and using it as a comparison target when the number of continuations of change is 1 or more can be considered.

In step S203 of FIG. 5 or step S306 of FIG. 6, the waiting time of the response waiting time update device 20 for the communication response from the second communication device 60 is updated to a value that monotonously increases according to the communication response time. At this time, for the new waiting time, for example, a value obtained by adding a predetermined margin value to the measured communication response time is used. The margin value is a value intended to wait for a communication response up to the range of the measured communication response time fluctuation in consideration of fluctuations in the communication response time. As the margin value, any value may be set as long as the waiting time can be set to a value as small as possible that monotonously increases in accordance with the communication response time. For example, a value that changes depending on the communication response time, such as a value of 50% of the communication response time, or a fixed value such as 1 second or 0.5 seconds can be used as the margin value. By doing so, the waiting time increases monotonously according to the communication response time, and is updated to a value larger than the communication response time by a margin value. Therefore, the waiting time of the response waiting time update device 20 for the communication response from the second communication device 60 can be updated to a value as small as possible while reducing the frequency of communication timeout.

Also, if the waiting time is too long, the response to the user's operation will be delayed so that it cannot wait. Therefore, it is desirable to set an upper limit for the waiting time. The upper limit value may be set to any value as long as possible so that the user can wait without a sense of incongruity. For example, it is conceivable to use a value of about several tens of seconds as the upper limit value.

Also, if the waiting time is too short, timeouts are likely to occur. Therefore, it is desirable to set a lower limit for the waiting time. The lower limit value may be set to any value as long as the user feels “immediately” as long as possible. For example, it is conceivable to use a value of 1 second or less or a value of several seconds as the lower limit value.

For example, if the margin value is 50% of the communication response time, the upper limit value is 20 seconds, and the lower limit value is 1 second, then 0.5 × 1.5 = 0. Since it is 75 seconds, the lower limit of 1 second is set as the waiting time. When the communication response time is 3 seconds, the waiting time is 3 × 1.5 = 4.5 seconds. When the communication response time is 15 seconds, 15 × 1.5 = 22.5 seconds, so the upper limit value of 20 seconds is set as the waiting time.

By operating in this way, the response waiting time update device 20 is set to a value that monotonously increases according to the communication response time between the response waiting time update device 20 and the second communication device 60. The waiting time of the response waiting time update device 20 for the communication response from 60 is updated. Thereby, when the delay of the communication response increases, the waiting time of the response waiting time update device 20 can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

As described above, in the second embodiment of the present invention, the response waiting time update device monotonously increases according to the communication response time between the response waiting time update device 20 and the second communication device 60. The waiting time of the response waiting time update device 20 for the communication response from the second communication device 60 is updated to the value. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

Also, since it is possible to automatically update the waiting time for the communication response, it becomes possible to suppress OPEX and reduce the possibility of an operation error compared with the case where the waiting time is adjusted manually.

In addition, when the communication response time decreases, the response waiting time for the communication response from the second communication device can be reduced, so that the waiting time of the user in a situation where a timeout occurs due to the occurrence of a failure or the like Can be reduced.

[Third embodiment]
Next, a third embodiment of the present invention will be described. In this embodiment, instead of providing the update function of the communication response waiting time in each server, the management response server centrally controls the communication response waiting time of each server.

First, FIG. 7 shows a configuration example of the response waiting time update device 30 of the present embodiment. In the present embodiment, the response waiting time update device 30 is a communication response waiting time management server.

The management server may be one of the servers that make up the vCPE system, or may be an external server that is separate from the servers that make up the vCPE system. Further, the function of the management server may be arranged on a server having other functions, or may be arranged on an individual server dedicated to management.

For example, the O & M server 75 may have a management server function. In this case, the response waiting time update device 30 is the O & M server 75. Since the O & M server 75 is a server that manages the status of each other server, the O & M server 75 communicates with each other server. Therefore, it is possible to easily introduce the update function.

The response waiting time update device 30 includes a waiting time update unit 11 and a response time receiving unit 33.

The response time receiving unit 33 is a part that receives a communication response time between the first communication device 40 and the second communication device 60. The second communication device 60 corresponds to a communication partner server of the first communication device 40. For example, when updating the waiting time of the Portal server 74 for the communication response from the NAT server 72, the Portal server 74 is the first communication device 40 and the NAT server 72 is the second communication device 60.

The waiting time updating unit 11 updates the waiting time of the first communication device 40 with respect to the communication response from the second communication device 60 to a value that monotonously increases according to the communication response time received by the response time receiving unit 33. Part. The waiting time update unit 11 determines the waiting time of the first communication device 40 and transmits it to the first communication device 40.

The first communication device 40 includes a response time measuring unit 42, a response time transmitting unit 44, and a waiting time receiving unit 45.

The response time measuring unit 42 is a part that measures the communication response time between the first communication device 40 and the second communication device 60 at predetermined intervals. The response time transmitting unit 44 is a part that transmits the communication response time measured by the response time measuring unit 42 to the response waiting time update device 30. The waiting time receiving unit 45 is a part that receives and updates the waiting time of the first communication device 40 for the communication response from the second communication device 60 from the response waiting time update device 30.

By configuring the response waiting time updating device 30 in this way, the response waiting time updating device 30 is a value that monotonously increases according to the communication response time between the first communication device 40 and the second communication device 60. In addition, the waiting time of the first communication device 40 for the communication response from the second communication device 60 is updated. Thereby, when the delay of the communication response increases, the waiting time of the first communication device 40 can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

Also, by introducing a management server, it becomes possible to minimize the expansion of functions of individual servers. Further, when the function is expanded later, it is possible to minimize the influence on other servers.

Next, FIG. 8 shows an operation example of the response waiting time update device 30 of the present embodiment, and FIG. 9 shows an operation example of the first communication device 40 of the present embodiment.

First, the response time measurement unit 42 of the first communication device 40 measures the communication response time with the second communication device 60 every predetermined time (step S501 in FIG. 9). And the response time transmission part 44 transmits the communication response time which the response time measurement part 42 measured to the response waiting time update apparatus 30 (step S502).

When the response time receiving unit 33 of the response waiting time update device 30 receives the communication response time between the first communication device 40 and the second communication device 60 from the first communication device 40 (step S401 in FIG. 8). YES), it is determined whether the communication response time has changed. If the communication response time has changed (YES in step S402), the waiting time of the first communication device 40 for the communication response from the second communication device 60 is determined to a value that monotonously increases according to the communication response time. Then, the response is sent to the response waiting time update device 30 (step S403).

When the waiting time reception unit 45 of the first communication device 40 receives the waiting time from the response waiting time update device 30 (YES in step S503 in FIG. 9), the first waiting time for the communication response from the second communication device 60 is received. The waiting time of the communication device 40 is updated (step S504).

Next, FIG. 10 shows an example of a communication sequence between the response waiting time update device 30 and the first communication device 40 of this embodiment.

First, the response waiting time update device 30 requests the first communication device 40 for the current setting value of the waiting time for the communication response (setting value of the communication response waiting timer) (step S601). The first communication device 40 responds to the response waiting time update device 30 with the set value of the waiting time (step S602). The response waiting time update device 30 holds the setting value of the waiting time (step S603).

The first communication device 40 measures the communication response time with the second communication device 60 every predetermined time (step S604), and transmits it to the response waiting time update device 30 (step S605). The response waiting time update device 30 determines whether or not the waiting time needs to be updated based on the received communication response time (step S606). When the update is necessary, the response waiting time update device 30 transmits a new waiting time to the first communication device 40 (step S607).

When receiving the new waiting time, the first communication device 40 updates the waiting time of the first communication device 40 (step S608) and transmits an update completion response to the response waiting time update device 30 (step S609). The response waiting time update device 30 updates the set waiting time value to a new waiting time (step S610).

By operating in this way, the response waiting time update device 30 is set to a value that increases monotonously according to the communication response time between the first communication device 40 and the second communication device 60. The waiting time of the first communication device 40 for the communication response from 60 is updated. Thereby, when the delay of the communication response increases, the waiting time of the first communication device 40 can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

As described above, in the third embodiment of the present invention, the response waiting time update device has a value that monotonously increases according to the communication response time between the first communication device and the second communication device. The waiting time of the first communication device for the communication response from the second communication device is updated. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

[Fourth embodiment]
Next, a fourth embodiment of the present invention will be described. The present embodiment is a form in which a function for notifying the status of communication response time to a CPE, a management apparatus, or the like is added to the response waiting time update apparatuses of the first to third embodiments.

First, FIG. 11 shows a configuration example of the response waiting time update device 50 of the present embodiment. In this embodiment, the notification part 56 is added with respect to the response waiting time update apparatus 10 of 1st embodiment. It is also possible to add a notification unit 56 to the response waiting time update device 20 in FIG. 4 and the response waiting time update device 30 in FIG.

The notification unit 56 is a part that notifies the CPE 70 of the status of the communication response time. Since the waiting time update unit 11 is the same as that of the other embodiments, description thereof is omitted. In addition to the CPE, the notification destination may be a management device or the like.

For example, if the communication response time exceeds the waiting time while the waiting time has reached the upper limit that can be set, the second communication device 60 is in an abnormal state and congestion has occurred. Or the network is in an abnormal state. In such a case, the CPE 70 is notified that the communication response time has become longer, and the CPE 70 displays a notification for requesting the user to access again after a period of time on the CPE setting screen. Or you may notify the message displayed on a CPE setting screen from the notification part 56 to CPE70.

In addition, after notification that the communication response time has become longer, when the waiting time is updated to a value lower than the upper limit value, or when the state where the communication response time is lower than the set waiting time continues for a predetermined period, The CPE 70 may be notified that the long communication response time has been resolved.

By configuring the response wait time update device 50 in this way, the response wait time update device 50 has a value that monotonously increases according to the communication response time between the first communication device and the second communication device. The waiting time of the first communication device for the communication response from the second communication device is updated. Thereby, when the delay of the communication response increases, the waiting time of the first communication device can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

Also, the response waiting time update device 50 of this embodiment can notify the user of the status of the communication response time by notifying the CPE of the status of the communication response time.

Next, FIG. 12 shows an operation example of the response waiting time update device 50 of the present embodiment. This operation example is an operation example in the case where the notification operation of the response waiting time update device 50 of the present embodiment is added to the operation example of the response waiting time update device 10 of FIG.

First, similarly to the response waiting time update device 10, the waiting time update unit 11 sets the second communication to a value that monotonously increases according to the communication response time between the first communication device and the second communication device. The waiting time of the first communication device for the communication response from the device is updated (step S101).

Then, when the updated waiting time is the upper limit value of the settable range (step S701), the notification unit 56 initializes the number of times exceeding the upper limit to 0 and starts counting the number of times exceeding the upper limit (step S702). In addition, the waiting time update unit 11 may perform the operation of counting the number of times exceeding the upper limit instead of the notification unit 56.

When the notification unit 56 starts counting the number of times exceeding the upper limit, when the communication response time is measured or received (step S703), the notification unit 56 checks whether the communication response time exceeds the upper limit (step S704). When the communication response time exceeds the upper limit value (YES in step S704), 1 is added to the upper limit count (step S705). If the number of times exceeding the upper limit is equal to or greater than the predetermined number (YES in step S706), the CPE 70 is notified that the communication response time is longer (step S707).

In step S704, if the communication response reception is equal to or less than the upper limit value (NO in step S704), the process returns to step S702 and the number of times exceeding the upper limit is initialized to zero. In addition, when the waiting time update unit 11 updates the waiting time and the waiting time is no longer the upper limit value (NO in step S701), the count operation for exceeding the upper limit is not performed.

By operating in this way, the response waiting time update device 50 increases the value from the second communication device to a value that monotonously increases according to the communication response time between the first communication device and the second communication device. The waiting time of the first communication device for the communication response is updated. Thereby, when the delay of the communication response increases, the waiting time of the first communication device can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

As described above, in the fourth embodiment of the present invention, the response waiting time update device has a value that monotonously increases according to the communication response time between the first communication device and the second communication device. The waiting time of the first communication device for the communication response from the second communication device is updated. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

Also, the response waiting time update device of this embodiment can notify the user of the status of the communication response time by notifying the CPE of the status of the communication response time.

[Fifth embodiment]
Next, a fifth embodiment of the present invention will be described. In the present embodiment, a method for performing priority control of the update operation of the communication response waiting time by the function provided by the first communication device or the second communication device will be described.

For example, the NAT server 72 in the vCPE system 71 of FIG. 3 is used when user terminals under the control of the CPE 70 communicate via the network 76. If a communication timeout occurs in the NAT server 72, the user terminal cannot access the network 76. Therefore, it is conceivable to preferentially update the communication response waiting time for the communication between the NAT server 72 and another server.

Further, the Portal server 74 in the vCPE system 71 of FIG. 3 is used for initial setting of CPE when a user contracts with a communication carrier and uses a service. Communication between the Portal server 74 and the NAT server 72 or between the Portal server 74 and the DHCP server 73 occurs when the user sets the CPE through the Web screen provided by the Portal server 74. If these communications fail, the CPE setting may not be completed and the CPE may not be able to provide a service. Therefore, at the time of setting the CPE, it is conceivable to preferentially update the communication response waiting time for communication between the Portal server 74 and another server.

The configuration example of the first communication device is the same as that in FIG. 4 or FIG. In this embodiment, the measurement interval of the communication response time in the first communication device is set to a measurement interval corresponding to the function provided by the first communication device or the second communication device.

Taking the case where the response waiting time update device and the first communication device have the configuration example of FIG. 7 as an example, the measurement interval of the communication response time in the response time measurement unit 42 of the first communication device 40 is set to the first The measurement interval depends on the function of the communication device 40 and the function of the second communication device 60.

By configuring the response waiting time updating device in this way, the response waiting time updating device is set to a value that monotonously increases according to the communication response time between the first communication device and the second communication device. The waiting time of the first communication device for the communication response from the communication device is updated. Thereby, when the delay of the communication response increases, the waiting time of the first communication device can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

In addition, by setting the measurement interval of the communication response time as a measurement interval according to the function provided by the first communication device or the second communication device, a communication response related to a communication device having a large influence when a communication timeout occurs It becomes possible to update by giving priority to the waiting time.

Next, an example of the operation of the response waiting time update device according to this embodiment will be described.

In this embodiment, the measurement interval of the communication response time in the first communication device is set to a measurement interval corresponding to the function provided by the first communication device or the second communication device.

For example, when the first communication device 40 is the Portal server 74, a communication response with the second communication device 60 (another server) at short intervals while the user is accessing the Portal server 74. Measure time. Further, after the access is completed, the measurement interval of the communication response time with the NAT server 72 is kept short, and the measurement interval of the communication response time with the other second communication device 60 is lengthened.

When the first communication device 40 is the NAT server 72, the communication response time with the second communication device 60 is measured at short intervals.

When the first communication device 40 is other than the Portal server 74 or the NAT server 72, the communication response time measurement interval with the Portal server 74 is shortened during the communication with the Portal server 74. When the communication with the Portal server 74 is completed, the measurement interval of the communication response time with the NAT server 72 is made shorter than other servers.

The measurement interval may be set in advance in the first communication device 40, or may be instructed to the first communication device 40 from a management device such as the response waiting time update device 30.

By operating in this way, the response waiting time update device communicates from the second communication device to a value that monotonously increases according to the communication response time between the first communication device and the second communication device. Update the waiting time of the first communication device for the response. Thereby, when the delay of the communication response increases, the waiting time of the first communication device can be increased to a value corresponding to the communication response time. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.

As described above, in the fifth embodiment of the present invention, the response waiting time update device has a value that monotonously increases according to the communication response time between the first communication device and the second communication device. The waiting time of the first communication device for the communication response from the second communication device is updated. Therefore, it is possible to reduce the frequency of communication timeout due to communication response delay.
