Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data exchange system and a data exchange network, and more particularly to a backup control means for the data exchange network, an inflow regulation releasing means, a failure monitoring means for the data exchange system, a network configuration information managing means, and a number translation. The present invention relates to information management means and communication amount management means.

[1. Summary of Invention]

[0003]

2. Description of the Related Art FIG. 45 is a diagram showing a schematic configuration of a data exchange system and a data exchange network in relation to the present invention.

When the communication amount of the dedicated line exceeds a predetermined value, backup control means 200 for connecting a normal line or a backup line using another dedicated line is provided. Further, when a failure occurs in a line or a relay node (including a source node and a destination node), an inflow restriction releasing means 100 is provided to restrict the inflow of data from the calling terminal and release the inflow restriction when the failure is released. To be

Further, when a failure occurs in a line or a partner node, it is necessary to immediately elucidate the cause and improve communication security.
When the data exchange system constitutes a network, each system needs to recognize which other system forms a network, and therefore each system is provided with the network configuration information management means 400.

Further, in order for the calling node to confirm the line to the called terminal at the time of calling, a number for managing the number translation data for checking the line to the called terminal from the destination address included in the calling data. The translation unit 500 is also provided with a communication amount management unit 600 that accumulates the communication amount and uses it for billing and the like.

[0007]

In the above configuration,
Regardless of whether or not the obstacle has been released, the inflow regulation releasing means 100 is designed to release the inflow regulation after a predetermined time defined by the timer has elapsed after the inflow regulation was applied. When the inflow restrictions were lifted when not, a large amount of invalid data was generated. Further, since the backup line control means 100 controls the disconnection of the backup line by referring to only the traffic volume of the own node, even if the destination node still needs the backup line, the backup line is controlled. Sometimes, the backup line could not be used efficiently.

Further, even if a failure occurs, the failure monitoring means 300 cannot immediately collect and display the line trace information, so that it takes much time in terms of maintenance and operation. In addition, the network configuration information management means 400 has a practical use of manually creating new network configuration information regarding the new node and registering it in the existing node when there is a new node, which requires a large amount of human labor. However, the method using the unified management node may not work when a failure occurs.

The number translation means 500 manages the translation information centrally or in a decentralized manner, but in any case, the fixed translation information is stored in the fixed storage means and is always stored at the time of calling processing. Since it becomes necessary to access the storage means, the load on the system is heavy. Further, in the communication amount management means 600, the obtained communication amount is used only for billing, and illegal use of the line, incorrect use,
Due to system runaway, it was not possible to process when the communication volume increased abnormally.

The present invention has been proposed in view of the above-mentioned conventional circumstances, and reduces the amount of invalid data, the effective use of a backup line, the speed of maintenance when a failure occurs, and the efficiency of network configuration information when a node is newly installed. It is an object of the present invention to provide a data exchange system and a data exchange network capable of performing automatic update, efficient use of translation information, and processing for abnormal traffic.

[0011]

To achieve the above object, the present invention employs the following means. That is, FIG.
As shown in FIG. 5, in the data exchange system, the backup control means 200 for controlling connection / disconnection of the backup line based on the traffic volume of the own node and the traffic volume of the partner node, and showing that the fault of the faulty node is recovered Inflow regulation releasing means 100 that releases the inflow regulation based on the recovery transmission signal, fault monitoring means 300 that detects the fault type and collects the line trace information of the fault portion when a fault occurs, and existing equipment from the new node. A new node notification information including information necessary for communication with the new node is transmitted to the node, and a new node response notification information including information necessary for communication with the existing node is transmitted from the existing node to the mutual network configuration. The network configuration information management means 400 for updating information and the number translation information corresponding to the called terminal at the time of calling are When it is not managed by the subsystem that manages the number, the translation information management means 500 that manages the translation information by the subsystem that obtains the translation information from another subsystem and manages the calling terminal, and the communication amount is equal to or more than a predetermined allowable amount. Communication processing means 600 for performing illegal reception processing when
It has a configuration including and.

[0012]

With the above structure, there is an effect that it is possible to obtain a data exchange system which has high security in terms of operation and which can ensure the convenience of installation and maintenance.

The above means will be described in more detail below. [ 2. Regarding inflow restriction release means ]

[0014]

2. Description of the Related Art FIG. 21 is a functional block diagram showing a prior art relating to an inflow regulation releasing means when a failure is detected, and FIG. 22 is a flow chart thereof.

When the line from the relay node B to the node C is broken, or when a failure occurs in the node C itself, the failure detection means 120 of the node B in the preceding stage of the node C is operated by the node C. Failure is detected and the content is stored in the failure node memory 101. In this state, when the data from the terminal a to the terminal b under the control of the node C arrives at the failure detection node B from the terminal a via the originating node A, the failure notification unit 114 of the failure detection means 120 of the failure detection node B. Operates to notify the source node A that a failure has occurred in the node C (or the line from the relay node B to the node C).

In response to this, the inflow regulation means 130 operates in the originating node A to regulate the inflow from the originating terminal a to the faulty node C. With this inflow restriction, the restriction release timer 105 of the restriction release means 140 operates, and when the restriction release timer 105 times out, the inflow restriction release unit 143 operates to release the inflow restriction for the terminal a. ing.

[0017]

According to the above-mentioned conventional configuration, when the restriction release timer 105 times out, the data transmission from the calling terminal a is resumed regardless of whether or not the failure of the partner node C is recovered. To be done. Therefore, if the failure is not recovered at this stage, the failure detecting means 1
20 and failure notification means 110, and inflow regulation means 130
Will operate again, and the inflow restriction will be applied to the terminal a.
If such an operation is repeated several times, a large amount of invalid data will be generated. Moreover, considering that it is not known when the failure will be recovered, the time set in the restriction release timer 105 needs to be shortened to some extent, and the shorter the set time, the larger the amount of invalid data.

The present invention has been proposed in view of the above conventional circumstances, and an object of the present invention is to provide a data exchange network equipped with an inflow regulation releasing means for preventing generation of a large amount of invalid data. is there.

[0019]

The present invention has been proposed in view of the above-mentioned conventional circumstances, and employs the following means.

That is, as shown in FIG. 2, when the failure detecting means 120 is provided in the relay node B and it is detected that there is a failure in the node C or the relay line at the subsequent stage, the failure notifying means 110 causes the originating node A. Failure notification to the originating node A
In the data exchange system in which the inflow restricting means 130 applies the inflow restriction to the calling terminal a, the calling node A stores the node number of the faulty node C which is the inflow restriction target after the inflow restriction is started, When the recovery transmission signal indicating that the failure is recovered is input, the restriction is released when the stored content of the restriction memory 102 and the node number of the failure recovery node C included in the recovery transmission signal match. The configuration is provided with the regulation releasing means 140.

When the recovery transmission signal is input, the restriction releasing means 140 is detected by the node analysis unit 141 that analyzes the node number of the failure recovery node C included in the signal and the originating node analysis unit 141. When the determined node is a regulated node, the regulated node search unit 142 that searches the regulated memory 102 to find out whether or not the regulated node is a regulated node; Release unit 1 for releasing the inflow regulation
43 can be provided.

Further, when the recovery transmission signal is data having the failure occurrence node C as the origination node, the node analysis unit 141 becomes the origination node analysis unit 141a which obtains the node number from the data.

When the relay node B is provided with a failure recovery notifying means 150 which issues a failure recovery notification to the originating node A when the failure detection means 120 detects the failure recovery of the failure occurrence node C, the recovery transmission is performed. The signal is a failure recovery notification, and the node analysis unit 141 becomes the failure recovery node analysis unit 141b that obtains the node number from the failure recovery notification.

After the inflow regulation by the inflow regulation means 130, the health check means 160 on the side of the originating node A for checking whether or not the failure is recovered from the failure detection node B at a predetermined time interval, When the health check response means 170 on the fault detection node B side for notifying the detection result of the fault detection means 120 corresponding to the health check is configured, the recovery transmission signal is transmitted from the health check response means 170. This is a recovery response notification, and the node analysis unit 141 becomes the response node analysis unit 141c that obtains the node number from the health check response.

Each of the configurations corresponding to the recovery transmission signal can be individually or combined with the conventional configuration.

[0026]

[Function] The source node A has a failure node C with respect to the source terminal a.
After the regulation of the inflow of data into the regulation memory 10 is started, the node number of the faulty node C that is the regulation target is the regulation memory 10.
Stored in 2. Then, when the recovery transmission signal indicating that the failure of the failure occurrence node C is recovered is input to the restriction release means 140, the restriction release means 140 recovers the failure of the failure occurrence node C based on the recovery transmission signal. Be sure to remove the restrictions.

When a recovery transmission signal is input to the restriction releasing means 140, the node analysis unit 141 first operates to analyze the node number of the node in which the failure contained in the signal is recovered. Then, the regulation node search means 142
However, whether or not the node number obtained as described above is the node number of the regulation target node C is determined by the regulation memory 1
02, the canceling unit 143 cancels the inflow restriction when it is determined that the search result is the restriction target node.

As the recovery transmission signal, data having the failure occurrence node C as the origination node can be used. When the relay node B is provided with the failure recovery notifying means 150, the failure recovery notifying means 1 is used as the recovery transmission signal.
The failure recovery notification output by 50 can be used.

Further, when the source node A side is provided with the health check means 160 and the failure detection node B side is provided with the health check response means 170, the health check response means 170 is used as the recovery transmission signal. It can be a recovery response notification to be output.

[0030]

FIG. 8 is a functional block diagram of an embodiment of the present invention, and FIG. 17 is a flow chart thereof.

The fault monitoring section 121 of the fault detecting means 120 of the relay node B constantly monitors whether or not a fault has occurred in the node C or the relay line from the node B to the node C. When a failure is detected by this, the node number of the failed node C is analyzed by the node analysis unit 122, and the analysis result is stored in the failed node memory 101.

In this state, when the relay node (fault detection node) B receives data, the destination node of the data is analyzed by the destination node analysis unit 111, and then the destination node fault search unit 112 causes the fault node to operate. By referring to the memory 101, it is searched whether the destination node detected by the destination node analysis unit 111 has a failure.

As a result, when the destination node has a failure, the reception data of the relay node B becomes invalid data, so the source node analysis unit 113 analyzes the source node A that has transmitted the invalid data, The failure notification unit 114 sends a failure notification to the originating node A.

At the source node A that has received the fault notification, the fault node analysis unit 131 of the inflow control means 130 operates to detect the fault node C having a fault. Then, the inflow regulation unit 132 operates to impose the inflow regulation on the calling terminal a, and the failure occurrence node C that is the regulation target
The node number of is stored in the regulation memory 102.

In this state, when the source node A receives data from another node, the source node analysis unit 141a of the inflow restriction releasing means 140 obtains the source node of the data received from the other node.

The regulation node searching means 142 detects whether or not the source node of the received data obtained as described above is subject to the inflow regulation by referring to the regulation memory 102.

As a result, when the regulated node C is the source node of the received data, it means that the fault of the node C has been removed, and therefore the regulation release unit 143 releases the inflow regulation. It is like this.

FIG. 9 is a functional block diagram showing another embodiment of the present invention, and FIG. 18 is a flow chart thereof. Fault detection means 1
The configuration and operation of 20 are the same as in the above example. Further, the configuration of the fault notifying means 110 is also the same as the above example, but the fault notifying section 114 issues a fault notice to the calling node A and the node (node A) which has issued the fault notice to the notice node memory 103. Remember the node number.

Upon receiving the above-mentioned fault notification, the fault detecting means 120
The restriction of inflow is similar to the above example. The failure detection means 120 of the failure detection node B is adapted to operate even after the failure notification, and when the failure detection means 120 detects failure recovery in the above state, the failure recovery notification means 1
The notification node search unit 151 of 50 operates to search for the node (node A) that has notified the failure, and the recovery notification unit 152 notifies the node A that the failure of the node C has been recovered. Further, after the notification to the node A, the recovery notification unit 152
The contents of the notification node memory 103 are erased.

The failure recovery notified in this way is received by the failure recovery node analyzing section 141b of the inflow restriction releasing means 140 of the originating node A, and the recovery node is detected.
Next, the restriction node search unit 142 searches whether or not this recovery node is subject to the inflow restriction stored in the restriction memory 102, and if it is the restriction target, the restriction release unit 143 operates. , The inflow regulation from the terminal a is released.

FIG. 10 is a functional block diagram showing another embodiment of the present invention, and FIGS. 19 and 20 are flow charts thereof. A fault is detected by the fault detecting means 120, and the fault notifying means 11
When the number is 0, the fault is notified to the calling node A. In addition, the failure detection means 120 of the source node A that has received the failure notification operates,
Restrict inflow. The above points are exactly the same as the above two examples.

In this embodiment, when the inflow regulation is further applied in this way, the health check means 1 provided in the source node A
60 is activated. That is, the notification timer 161 operates the health check notification unit 162 at a predetermined interval after the inflow regulation is started. As a result, the fault detection node B
A health check for inquiring whether or not the failure of the failure node C has been recovered is notified to the health check response means 170 provided in FIG.

On the other hand, the fault detecting means 120 is still operating after the fault notification, and when the fault is recovered, the fact is written in the fault memory 101. When the health check is performed by the calling terminal node A in this state, the analysis unit 171 of the health check response unit 170 detects the node (node C in this case) that is the target of the health check, and the inquiry node search of the next stage is performed. The state of the node C detected by the unit 172 (whether the fault is continuing or recovering) is stored in the fault memory 101.
And the response transmitting unit 173 issues a recovery when the failure is recovered and outputs an unrecovered response when the failure is not recovered.

In response to this, the response node analysis section 141c of the restriction releasing means 140 operates to analyze which node the response corresponds to. The analysis result obtained in this way and the regulation target node (C in this case) stored in the regulation memory 102 are compared by the regulation node search unit 142, and when they match, the regulation release unit 143 operates to regulate. Will be canceled.

FIG. 11 shows the conventional technique shown in FIG. 21 and FIG.
7 is a functional block diagram of an embodiment in which the embodiment of the present invention shown in FIG. That is, when the deregulation means 140 of the originating node A receives data in which the faulty node is the originating node, or when a predetermined time has elapsed (the deregulation timer 105 has timed out) after the inflow regulation was applied, the inflow regulation is restricted. I am trying to release it. In the conventional system, since it is not known when the failure will be recovered, it is necessary to set the predetermined time in the deregulation timer 105 to be short to some extent, but the above configuration allows the timer setting time to be made to be somewhat long.

FIG. 12 is a functional block diagram showing an embodiment in which the embodiment of the present invention shown in FIG. 9 and the prior art are used together. That is, the inflow restriction is released when the failure recovery notification unit 150 gives a failure recovery notification or when the time set by the restriction release timer 105 elapses.

FIG. 13 is a functional block diagram showing an embodiment in which the embodiment of the present invention shown in FIG. 10 and the prior art are used together. That is, the inflow regulation is released by checking the failure recovery by the health check or by the regulation release timer 105 timing out. In this case, the set time of the notification timer 161 of the health check means 160 is shorter than the set time of the timer 105 (for example, 1 /
10)) and repeat the health check to release the inflow restriction at longer intervals. As a result, the amount of invalid data is dramatically reduced as compared with the conventional case.

FIG. 14 shows an embodiment of the present invention shown in FIG. 8 and FIG.
The embodiment of the present invention shown in FIG. That is, the data whose source node is the faulty node C is the source node A.
Will be released when the notification is received or when there is a failure recovery notification from the failure recovery notification means 150. As a result, even if one of the functions is uncertain, the other function is activated and the inflow regulation is released, thereby increasing the reliability of the device.

FIG. 15 shows an embodiment of the present invention shown in FIG. 9 and FIG.
It is a functional block diagram which shows the Example of this invention which used the Example of this invention shown in 0 together. That is, the fault notifying means 11
The inflow regulation will be released depending on whether there is a failure recovery notification from 0 or whether the failure is recovered by the response corresponding to the health check by the health check means 160.

FIG. 16 shows an embodiment of the present invention shown in FIG. 8 and FIG.
It is a functional block diagram of the present invention which also used the embodiment of the present invention shown in FIG. That is, the inflow regulation is released when the data having the faulty node C as the source node is received by the source node A or when the health check means 160 detects the fault recovery.

[0051]

As described above, according to the present invention, the inflow regulation is released after some method confirms the recovery of the failure of the failed node, so that there is an effect that the invalid data disappears. Further, by using the present invention and the prior art together, it is possible to lengthen the inflow regulation interval by the timer in the prior art and reduce the invalid data.

Further, by reliably combining the embodiments of the present invention with each other or by combining the embodiments of the present invention with the prior art, it is possible to obtain an inflow restriction releasing procedure that operates reliably. [ 3. About backup control means ]

[0053]

2. Description of the Related Art When communication is performed through a dedicated line, when a traffic volume on the dedicated line exceeds an allowable amount, a normal line is used as a backup line, and the backup line is set in this way. The backup line is disconnected when the traffic amount decreases below a predetermined value. At this time, the number of backup lines can be sequentially increased or decreased as needed.

FIG. 26 shows a conventional backup line connection,
FIG. 27 is a functional block diagram regarding disconnection, and FIG. 27 is a conceptual diagram for explaining the operation. The node D is provided with the traffic monitoring means 210a to constantly monitor the amount of traffic transmitted from the own node D to the partner node E. Here, the traffic amount from the node D to the node E is the throughput between the node D and the node E (throughput of the dedicated line and total throughput of the backup line and the dedicated line when a backup line is set) Th When the above is reached, transmission waiting data is generated.

When data waiting to be transmitted is generated in this way, the traffic monitoring means 210a activates the backup line connection control means 250, whereby the line switching means 260a connects the normal line as a backup line. On the other hand, when the amount of traffic waiting to be transmitted becomes less than the current throughput Th in the state where the backup line is connected as described above, there is no data waiting to be transmitted and the traffic monitoring means 210a activates the backup line connection control means 250. Then, the line switch means 260a disconnects the backup line.

[0056]

As described above, in the conventional procedure of connecting and disconnecting the backup line, the backup is performed based on only the traffic amount from the own node D to the destination node E (or node E to node D). It is designed to control the connection of lines.

However, as shown in FIG. 28, even when the amount of traffic from the node D to the node E is lower than the throughput Th from the node D to the node E and there is no waiting data, the node E to the node D does not exist. The amount of traffic to the network may still be greater than the current throughput Th.

In the above case, if the backup line is unilaterally disconnected based on only the status of the node D, the backup line disconnected by the node D needs to be set again by the node E. Is not used effectively, and invalid data will be generated during this period.

The present invention has been proposed in view of the above conventional circumstances, and an object of the present invention is to provide a data exchange network for disconnecting a backup line based on bidirectional traffic volume.

[0060]

The present invention employs the following means in order to achieve the above object. That is, FIG.
As shown in FIG. 5, in the data exchange system in which the own node D and the partner node E are connected by a dedicated line and the connection control of the backup line is controlled based on the transmission waiting traffic amount detected by the traffic monitoring means 210a, the traffic monitoring When the means 210a detects that the amount of traffic waiting to be transmitted becomes less than or equal to a predetermined value, the own node D
And a collection / analysis unit 230 for collecting and analyzing information regarding disconnectability of the partner node E, and the collection / analysis unit 2
The backup line connection control means 250 that operates based on the analysis result of 30 is provided.

The collection / analysis means 230 inquires of the destination node E whether or not to disconnect, and based on the response from the destination node E, the backup line connection control means 25.
0 and disconnectability inquiry means 2 for issuing an instruction of disconnectability
It may be configured by 31a.

Further, in the case of the above-mentioned configuration, the disconnection propriety response means 2 which responds to the destination node E by the disconnection propriety in response to the inquiry of the disconnectability propriety inquiry means 231a.
31b and a disconnectability determination means 240 for notifying the disconnectability response means 231b of the disconnectability determination result based on the notification from the traffic monitoring means 210b.

As the collection / analysis means 230, the throughput inquiry means 232a for collecting the required throughput amounts of the own node D and the partner node E, and the own node D's necessity based on the throughput amount collected by the throughput inquiry means 232a. The difference calculation means 235 for calculating the difference between the larger one of the throughput and the required throughput of the partner node E and the total throughput of the backup line and controlling the backup line connection control means 250 based on the difference is provided. It can also be configured.

With this configuration, the destination node E is
Throughput response means 232b for notifying the throughput amount in response to the inquiry of the throughput inquiry means 232a is provided.

The collection analysis means 230 further collects the required throughput of the own node D and the bidirectional throughput calculation means 233 for calculating the throughput received from the destination node E from the backup line, and the bidirectional throughput calculation means 233. Based on the information, the difference between the required throughput of the own node D and the larger throughput of the destination nodes and the total throughput of the backup line is calculated, and the difference calculation for controlling the backup line connection control means 250 is calculated based on the difference. And a means 235.

The inquiry to the destination node E by the collection / analysis means 230 is sent to the backup line, own node D.
Either a dedicated line between the destination node E and the destination node E or a dedicated line reaching the destination node E via the third node can be used.

[0067]

When the traffic monitoring means 210a detects that there is no data waiting to be transmitted from the own node D to the destination node E, the collection / analysis means 230 collects information regarding whether or not the destination node E can be disconnected, and the backup line The connection control means 250 controls the line switching means 260a based on this result. As a result, not only the status of the own node D but also the status of the partner node E is reflected in the disconnection of the backup line and the connection control.

When the disconnectability inquiry means 231a is used as the collection analysis means 230, the disconnectability inquiry means 231a inquires of the destination node E whether the disconnection is possible. When the response from the partner node E is disconnectable, the backup line connection control means 250 activates the line switch means 260a to disconnect the backup line.

Disconnectability response means 231 of the destination node E
When the inquiry is made from the disconnectability inquiring means 231a as described above, b inquires the disconnectability determining means 240 about the disconnectability determining result. On the other hand, the disconnectability determination means 240 inquires about the monitoring result of the traffic monitoring means 210b, determines the disconnectability based on the result, and notifies the disconnectability response means 231b.

In the above example, the destination node E determines whether or not the disconnection is possible, but the destination node E can also receive the required throughput to the own node D and the own node D can also determine whether or not the disconnection is possible. .

That is, the disconnection availability inquiry means 2
Throughput inquiry means 232a instead of 31a
Is provided. As a result, the throughput inquiry unit 232a collects the required throughput from the own node D to the partner node E and the required throughput from the partner node E to the own node D. The larger one M of the required throughputs at the time of transmission and reception thus collected is compared with the total throughput N of the backup line, and the backup line connection is made based on the value of the difference M−N calculated by the difference calculating means 230. The control means 250 is the line switch means 260
Start a.

Although the reception throughput may be notified from the destination node E, it may be detected by the bidirectional throughput calculating means 233 provided in the own node D based on the reception amount from the destination node. Of course good things.

[0073]

23 is a functional block diagram showing an embodiment of the present invention. The traffic monitoring means 210a constantly monitors the amount of transmission traffic from its own node D, and the traffic amount becomes lower than the current throughput Th,
When there is no data waiting to be transmitted, the disconnectability inquiring means 231a, which is the collecting and analyzing means 230, is activated.

Thus, the disconnectability inquiry means 23
1a inquires via the inter-station communication means 220a of its own node D and the inter-station communication means 220b of the destination node E to the disconnectability response means 231b of the destination node E whether the disconnection is possible. Receiving this, the disconnectability response unit 231b inquires the disconnectability determination unit 240 about availability of disconnection.

Similarly to the above, the traffic monitoring means 210b monitors the amount of transmission traffic from the node E to the node D, and when the disconnectability determination means 240 receives the inquiry, the traffic monitoring means 210b receives the current traffic amount. It inquires (whether the value exceeds the reference value Th), and notifies the disconnectability response means 231b based on the response whether disconnection is possible or not.

The disconnectability response means 231b further notifies the disconnectability inquiry means 231a of the determination result of the disconnectability determination means 240. The disconnectability response means 2
When the response from 31b is disconnectable, the backup line connection control means 250 activates the line switch means 260a to disconnect the backup line. When a plurality of backup lines are connected, one backup line is disconnected first, and if there is no waiting data in both node D and node E, further disconnection processing is performed.

FIG. 24 shows another embodiment of the present invention. When the traffic monitoring means 210a detects that there is no waiting data from the own node D to the partner node E, the throughput analysis means 232a, which is the collection analysis means 230, operates and the throughput calculation means 280a of the own node D causes the own node D The required throughput of D (the throughput required to transmit the data waiting to be transmitted, and the calculation method of the required throughput will be described below) is collected, and the throughput response means 232 of the destination node E is collected.
Inquire b about the required throughput of the destination node.

As a result, the throughput response means 232
b collects the required throughput of the node E from the throughput calculating means 280b. The required throughput of the destination node E obtained in this way is calculated by the throughput inquiry means 2 via the throughput response means 232b.
32a.

Here, the throughput calculating means 280a,
280b performs the following calculations. That is, the amount of data waiting to be transmitted (packet length in packet communication) is X (bit)
, The time required to transmit the data waiting to be transmitted is T (sec)
Then, the required throughput is represented by X / T (bps).

On the other hand, the total of the line speeds of the backup lines currently set is L (bps), and the difference between the required throughput of the own node D and the partner node E calculated above is larger. , L−X / T (bps) is the surplus of the backup line, the backup line can be disconnected within the range of L−X / T (bps).

Then, the difference calculating means 235 calculates the difference, and the backup line connection control means 250 gives an instruction to disconnect the backup line number according to the difference. As a result, the line switching means 260a disconnects the required number of lines.

The disconnection availability inquiry means 231a or the throughput inquiry means 232a makes an inquiry to the destination node E by using a backup line, a dedicated line, or a dedicated line set between the nodes D and E. Instead, a method of using a dedicated line from the node D to the node E via another node can be adopted.

FIG. 24 shows still another embodiment of the present invention. As described above, the throughput is set to the destination node E.
Instead of inquiring to the destination E, the throughput of the destination E is determined based on the amount of reception from the destination E.

That is, the destination node E from the own node D
The throughput waiting for transmission to (required throughput) can be calculated as described above. Next, the destination node E
The required throughput through the backup line to the own node D is calculated as follows.

That is, the backup three lines β, γ, δ
Letting B, Γ, and Δ be the utilization rates for a predetermined time, the required throughput in the receiving direction (bps) = B × β line speed + Γ × γ line speed + Δ × δ line speed.

The processing in the difference calculation means 235 and the processing in the backup line connection control means 250 are the same as in the above example.

[0087]

As described above, according to the present invention, since the traffic volume of the destination node is also referred to when disconnecting the backup line, the necessary backup line is not disconnected, and the backup line is effective. As it is used, it has the effect of reducing the incidence of invalid data.

[ 4. About fault monitoring means ]

[0089]

2. Description of the Related Art When a failure occurs in a data exchange system, failure monitoring means is provided for promptly searching the cause of the failure and dealing with it.

FIG. 34 is a functional block diagram of conventional fault monitoring means. When the failure detecting means 301 detects a failure in the used line, the restricting means 302 operates as necessary to restrict the incoming flow to the calling terminal. On the other hand, the fault detected by the fault detecting means 1 is stored in the fault memory 303, and the contents of the storing means 303 can be arbitrarily retrieved by the maintenance person from the maintenance console 340 so that the fault occurrence line and time can be confirmed. Has become.

On the other hand, the trace information memory 360 collects and stores the trace information data flowing through each line.
Therefore, the maintenance person who knows the fault as described above accesses the trace information memory 360 to retrieve the line trace information of the stage before the fault occurrence time for the faulty line and investigate the cause of the fault. .

The above-mentioned causes of failure are roughly classified into physical level failures, data link level failures, and packet level failures. The physical level failure mainly means disconnection of the line, and causes a phenomenon corresponding to, for example, the SD line (data transmission line), the RD line (data reception line) or other various control lines.

A failure at the data link level is a state in which communication is physically impossible even though the line is physically connected, and is caused by, for example, a serial number error, an address error, etc., and a retry out (unable to retransmit). It becomes a phenomenon.

A packet level failure is a packet dropout,
A transmission stop request packet (CQ packet) or a reset request packet (RQ) that has a failure area in which the type of failure occurs and is generated due to no response, packet sequence number error, etc.
Packet) is transmitted from the failure detection node.

[0095]

According to the above-mentioned conventional system, the cause of the fault is limited to the faulty line, and the line trace information of the line is examined. However, the cause of the failure may occur in the partner line of the line in which the failure is detected. According to the above conventional system, the line trace information of the partner line cannot be collected, which is one-handed.

Further, some failures may occur irregularly and may recover immediately. However, since the capacity of the fault memory 303 that records the occurrence of the above-mentioned fault or the trace information memory 360 that stores the line trace information is limited, the fault or line trace information stored in the fault memory 303 must not be held in a predetermined amount or more. become. Therefore, when a long time has passed since the failure occurred,
Sometimes it becomes impossible to recognize what kind of failure is occurring.

The present invention has been proposed in view of the above conventional circumstances, and is capable of recognizing a cause of a failure in real time and exchanging data with a failure inspection means capable of editing line trace information according to the cause of the failure. The purpose is to provide a system.

[0098]

The present invention employs the following means in order to achieve the above object. That is, FIG.
As shown in FIG. 3, in the data exchange system in which the failure detecting means 310 detects a communication failure, the failure analyzing means 320
Then, the type of the fault detected by the fault detecting means 310 is analyzed, and the collection destination of the line trace information is determined by the analysis table 370 according to the fault type obtained by the fault analyzing means 320, and the analysis is performed. Table 370
Based on the obtained line trace information collection destination, the line trace information is collected by the line trace collection means 340.

In the above description, the line trace information obtained by the line trace collection means 330 is edited in an edit format suitable for display and transmitted to the display means 350.

The failure analysis means 320 is further provided with a physical level failure analysis means 321, a data link level failure analysis means 322, and a packet level failure analysis means 323. Further, the failure analysis means 320
Can be configured to include a multilink line analyzing means 324 which detects a line under the multilink when the generated fault is a fault related to the multilink line.

The collection destination of the line trace information defined by the analysis table 370 may be a faulty line or a faulty line and its partner line depending on the fault type.

The failure analysis means 320 defines the editing format in the editing means 330 according to the failure type, and in particular, the packet level failure analysis means 323 defines only the editing format at the packet level according to the failure type. Define or edit format at packet level and data link level.

[0103]

According to the failure type obtained by the failure analysis means 320, the collection destination of the line trace information is determined from the analysis table 370. On the basis of the collection line determined in this way, the line trace collection means 330 causes the trace information memory 36
Collect trace information from 0.

The trace information collected as described above is
It is transmitted to the editing means 340 via the failure analysis means 320, where the line trace information is edited according to the editing format defined by the analysis table 370, and the display means 35 is displayed.
Display at 0.

The fault analysis means 320 further includes a physical level analysis means 321 and a data link level analysis means 322.
And a packet level analysis means 323 for determining whether a physical level failure, a data link level failure, or a packet level failure, and an analysis means 32 corresponding to each level.
Check 1, 322, 323 for more detailed failure types. The failure analysis means 320 further includes the multilink analysis means 3
If 24 is provided and the faulty line is a multilink line, a plurality of lines under the multilink are confirmed, and line trace information from the plurality of confirmed lines is collected in the line trace collection means 3. To instruct.

Depending on the type of fault, it may be necessary to collect the line trace information only from the faulty line, or it may be necessary to collect the line trace information from both the faulty line and its partner line. Therefore, the analysis table 370 defines which of the above cases is according to the failure type.

Furthermore, packet level failures may occur due to data link level failures. Therefore,
When a packet level failure occurs, depending on the failure type, it is necessary to use both an edit format that can analyze the packet level failure cause and an edit format that can analyze the packet level failure cause. Therefore, the packet level failure analysis means 323 defines the editing format in the editing means 330 according to the failure type.

[0108]

FIG. 29 is a conceptual diagram of an embodiment of the present invention. When the failure detection unit 310 detects a physical level failure, the failure analysis unit 320 confirms that the failure is at the physical level, and activates the physical level failure analysis unit 321.
The physical level fault analysis unit 321 further analyzes the fault signal detected by the fault detection unit 310 to determine whether the fault type is, for example, the SD line (data transmission line) or the RD line (data reception line). Detects whether or not the disconnection has occurred.

When the fault detecting means 310 detects a fault at the data link level, the fault analyzing means 320 confirms that the fault is at the data link level and activates the data link level analyzing means 322. The data link level failure analysis means 322 further uses the failure detection means 310.
The fault signal detected by is analyzed to detect a fault type, that is, a fault type such as Ritsuryout.

The fault detecting means 310 causes the transmission stop request packet (CQ packet) or the reset request packet (R
Q packet) is received and the failure analysis means 320 is notified that a failure at the packet level has occurred, the failure analysis means 320 confirms that the failure is at the packet level, and operates the packet level analysis means 323. Let
The packet level fault analysis unit 323 further detects the fault type by reading the fault cause written in the fault area of the CQ packet or RQ packet of the fault detection unit 310.

Each of the failure analysis means 321, 322, 32
Reference numeral 3 detects the obstacle type and also provides an editing format according to the obstacle type. When the fault is at the physical level or at the data link level, it is sufficient if the state in which the fault at that level has occurred can be displayed on the display means 350, so the above-mentioned editing format is determined in a unified manner.

When the failure is at the packet level, the true cause of the failure may be a data link level failure. Therefore, edit the trace data in which a packet level failure phenomenon is occurring depending on the failure type, or edit to understand the state in which both a packet level failure and a data link level failure are occurring. The format is also defined by the packet level failure analysis means 323.

The line trace information collection destination is extracted by referring to the analysis table 370 based on the fault type detected as described above. That is, depending on the failure type, not only the cause of the failure, but also the cause of the communication partner line. Therefore, it may not be sufficient to collect the following line trace information from only one line. Therefore, as shown in FIG. 31, the trace information collection destination according to the failure type is registered in the analysis table 370, and the trace information collection destination data according to the failure type is obtained.

On the basis of the trace information collection destination data obtained from the analysis table 370 as described above, the line trace collecting means 330 collects the line trace information from the trace information memory 360 in which the trace information of a predetermined line is stored. Will be done.

The line trace information collected from the necessary lines in this way is input to the editing means 340 via the failure analysis means 320. On the other hand, the edit format obtained by the level failure analysis means 321, 322, 323 as described above is held in the failure analysis means 320 while the line trace collection means 330 collects the line trace information as described above. , And the line trace information are input to the editing means 340.

The editing means 340 edits the line trace information according to the editing format, inputs the edited trace information into the display means 350, and identifies the fault type (for example, a code) obtained from the analyzing means 310. Displayed together.

By the way, in order to ensure the security of data transmission, a multi-linter line in which a plurality of physical lines constitutes one logical line may be used. When the physical link and the logical link are the same single-link line, the above configuration will be sufficient, but when using the multi-link line, the configuration shown in FIG. 30 is further adopted. In other words, the data link level failure analysis means 322 and the packet level failure analysis means 323 determine if the failed line is a multilink line (the determination means for determining whether or not there is a multilink line is made by a determination means (not shown). The analysis means 320 already knows that). The multilink line analysis means 324 identifies the lines under its control.

Based on the fault type and fault line thus identified, the line trace information collection destination is confirmed from the analysis table 370 shown in FIG. 31 similarly to the above. Next, the line trace collecting means 330 collects the trace information for all the lines detected by the multilink line analyzing means 324.

Further, the editing means 340 edits the trace information collected as described above for each line or in time series according to the editing method and displays it on the display means 350.

32 (a) and 32 (b) show an embodiment of the contents of the analysis table 360. FIG. 32 (a) shows a method for determining the amount of line trace information to be collected by the line trace collection means 3 (for example, the read initial address and read end address of the trace information memory 360), and FIG. Shows how to decide by time.

[0121]

As described above, according to the present invention, as soon as the fault detecting means detects a fault, it is possible to collect the trace information based on the fault type and display the trace information. Fault detection and fault check can be performed almost simultaneously. Further, since the trace information is collected not only from the faulty line but also from the partner line, the cause can be captured even when the partner line is causing the fault.

A plurality of subsystems F, G, ... Are arranged in the data exchange system, and each subsystem F, G ,.
In, a predetermined number of terminals fi, gi, ... (i: subscript assigned to each terminal) or other nodes (not shown) are managed. Further, the data exchange system is provided with a management system M including a storage means 510m storing number translation information corresponding to all terminals fi, gi, ...

In such a data exchange system,
For example, when there is a call request from the terminal f1 connected to the line managed by the subsystem F to the terminal g1 connected to the line managed by the subsystem G, the call control means 550-1 of the subsystem F The destination address of the called terminal g1 included in the call request signal is obtained. In response to this, the call control means 550-1 of the subsystem F has the storage means 510m.
By referring to the number translation information in the destination address, the accommodating position of the destination terminal g1 (in this case, subsystem G and destination terminal g
Recognize the line that connects 1) and perform the prescribed call control processing.

FIG. 39 is a conceptual diagram showing the structure of another data exchange system. In this example, each subsystem F,
G, ... Is provided with a storage means 510, and all terminals fi, gi
, ... The number translation information corresponding to the plurality of storage means 5
10 are distributed and managed.

Therefore, in the data exchange system having such a configuration, when a call request from the terminal g1 is issued from the terminal f1 as in the above example, the destination address of the destination terminal g1 indicated to the subsystem F is set. Based on the call control means 5
First, 50-1 refers to the number translation information in the storage means 510 in the subsystem F.

At this time, if the number translation information corresponding to the destination terminal g1 is stored in the storage means 510-1 of the subsystem F, the call control means 550-1 performs the call connection processing. If the number translation information corresponding to the destination terminal g1 is not stored in the storage unit 510-1 of the subsystem F, the call control unit 550-1 stores the storage unit 510-2 of the other subsystem G, ... , ..., referring to the number translation information, the destination terminal g
The call control process is performed by obtaining the number translation information corresponding to 1.

Also, the storage means 510- shown in FIG.
Each of 1, 510-2, ... Stores the number translation information corresponding to all terminals fi, gi, .. By this, the call control processing between any terminals manages the calling terminal. It can also be made possible within the system.

[0153]

However, in the data exchange system configured as shown in FIG. 38, all terminals fi and gi are stored in the storage means 510m of the management system M.
Since the number translation data related to, ...

It is necessary to perform call control processing after exchanging the number translation information between the subsystems F, G,
... and the management system M (memory means 510m) have a drawback that a large processing load is applied.

Also in the configuration shown in FIG. 39, the number translation information corresponding to the called terminal gi indicated by the calling request from the calling terminal fi is stored in the storage means 510-1 of the subsystem F that manages the calling terminal fi. If not, the number translation information is exchanged by a plurality of subsystems as in the above case, and there is a drawback that the processing load in the entire system cannot be reduced as in the above case.

In addition to the above-mentioned drawbacks, in the configuration shown in FIG. 39, it is difficult to know in which storage means the number translation information relating to a certain specific terminal is stored, and the operation such as maintenance of the number translation information is performed. This will increase the complexity of the aspect.

Further, in the configuration in which the number translation information corresponding to all the terminals is stored in all the storage means 510, the storage means of a large capacity must be secured in the entire data exchange system, and the resource saving In terms of effective utilization, it is extremely disadvantageous compared to the former two system configurations.

The present invention has been made in view of the above-mentioned conventional circumstances, and is a data exchange provided with a number translation means for reducing the processing load of the entire system and saving the storage capacity of the number translation information. The purpose is to provide a system.

Further, after the translation information collecting means 530 registers the number translation information corresponding to the destination terminal gi in the storage means 510, the call control processing is performed based on the number translation information, or the number translation information is registered. After that, a call connection processing requesting means 540 (shown by a broken line in FIG. 6) for requesting the call connection processing corresponding to the destination terminal gi to the collection destination subsystem G may be provided.

When a call is made from the calling terminal fi, the call control processing is performed based on the number translation information corresponding to the called terminal gi already registered in the storage means 510.

The number translation information may be distributedly managed by a plurality of subsystems or may be centrally managed by a single subsystem.

[0162]

According to the configuration of the present invention shown in FIG. 6, the number translation information corresponding to the destination terminal gi which has undergone the call control processing at least once is registered in the storage means 510 by the translation information collecting means 530. Therefore, after this, the subsystem F

The number translation information corresponding to all terminals fi, gi, hi, ... Is distributed and stored in each of the storage means 510. The storage means 510, the reference means 520, and the translation information collection means 530 are shown with hyphenated subscripts corresponding to each subsystem F (G, H, ...).

In the data exchange system having such a configuration, for example, there is a call request from the terminal f1 connected to the line managed by the subsystem F to the terminal g1 connected to the line managed by the subsystem G. The call control process for the case is as follows.

That is, first, the number translation information corresponding to the destination terminal g1 is registered in the storage means 510-1 based on the destination address contained in the call request from the terminal (hereinafter referred to as the calling terminal) f1. Reference means 520-1
Refer to.

As a result, if the number translation information corresponding to the destination terminal g1 is registered in the storage means 510-1, the accommodation position of the destination terminal g1 (in this case, from the destination address obtained by the call request signal). The line connected to the destination terminal g1) is notified to the call control means 550-1, whereby the calling terminal f1 is notified.
Call control processing is performed by the subsystem F that manages the.

If the number translation information corresponding to the destination terminal g1 is not registered in the storage means 510-1, the reference means 520-1 notifies the translation information collecting means 530-1 of this fact, and this is notified. The received translation information collection means 530-1 collects the number translation information of the destination terminal g1 from another subsystem (not necessarily G) and registers the number translation information in the storage means 510-1.

Thereafter, the reference means 520-1 is the call control means 5
50-1 is notified of the number translation information corresponding to the destination terminal g1 and the call control processing is performed. The operations of the reference unit 520-1 and the translation information collection unit 530-1 as described above are common to all the subsystems F, G, H, ... When a call request is made to the terminal corresponding to the number translation information not registered in the storage means 510, the number translation information relating to the terminal is newly additionally registered in the storage means 510. Then, even if there is a call request for the same terminal next time, the subsystem F (G,
H, ...) Can perform call control processing independently.

Therefore, with such a configuration, the number translation information corresponding to the called terminal gi which has been subjected to the call control processing even at least once is registered in the storage means 510 by the translation information collecting means 530. In performing call control processing of all terminals fi managed by the subsystem F and the destination terminal gi, other subsystems G, H,
It becomes unnecessary to collect the number translation information, and the processing load of the data exchange system is reduced.

Moreover, not only is the resource wasted,
Since the number translation information corresponding to the terminal that has performed the call control process in the past is accumulated in each storage unit 510, the processing efficiency of the entire system is improved.

FIG. 37 is a block diagram of another embodiment according to the present invention. As shown in FIG. 37, the data exchange system of this embodiment has a predetermined number of terminals fi, gi, hi.
In addition to arranging a plurality of subsystems F, G, H, ... Which manage ..., All of the above terminals fi, gi, h
Storage means 510m for storing number translation information relating to i, ...
And a call control means 550m that performs call control processing when a call control request described later is received from the subsystem F (G, H) that manages the calling terminal.

Also, each subsystem F (G, H) is common to each subsystem of the embodiment shown in FIG. 35 in that it includes a storage means 510, a reference means 520, and a translation information collection means 530. However, in this embodiment, the call connection processing requesting means 540 is further provided.

In such a configuration, when the number translation information necessary for the call control processing in response to the call request is not registered in the storage means 510, the translation information collecting means 530 causes the storage means 510m of the management system M. After collecting the number translation information, the number translation information is registered in the storage unit 510. Further, after the collection, call connection processing requesting means 54
0 requests the management system M, which is the collection destination, to perform a call connection process, and the call control means 550m that receives the request performs a predetermined call control process.

In such a configuration, the number translation information corresponding to all terminals is stored in the storage means 5 of the management system M.
It is managed centrally at 10 m, and only the number translation information corresponding to the terminal of the other party who has made a call request in the past is accumulated in the storage means 510 of each subsystem F (G, H). For example, it is not necessary to store the number translation information in each storage unit 510 in the initial state immediately after the system is installed, and the resource saving effect is further enhanced.

If there is a call request by the call requesting means 540, the call control process is immediately performed.
The present invention is not limited to the above embodiments, and for example, the data exchange system does not necessarily have to be composed of a plurality of subsystems, and a data exchange system having only one subsystem having the above configuration. The object of the present invention can be achieved even if a plurality of lines are connected.

[0179]

As described above, according to the present invention, the subsystem provided with the call control means connected to the terminal is provided with the storage means, the reference means and the translation information collection means, so that the call can be made at least once. Since the number translation information corresponding to the destination terminal for which the control process has been performed is always registered in the storage means, the number translation information corresponding to the terminal may be exchanged with the outside thereafter. And the processing load of the entire data exchange system is reduced.

Moreover, since the number translation information reflecting the results of the call control processing is accumulated in the storage means over time,
This has the effect of improving processing efficiency and saving resources.
