The connection relationship with is omitted in the figure.

In the figure, the solid line connecting the preliminary management system 60 and the basic management system 50 and the solid line connecting the basic management system 50 and the managed system 20 are in the normal state, and the preliminary management system 60 and the managed system 20 are shown. A broken line connecting the and indicates the state of the basic management system 50 at the time of failure.

FIG. 5 shows the operation of the monitoring means 19b in the preliminary management system 60. The monitoring side (referred to as the preliminary management system 60 side) and the monitored side (referred to as the basic management system 50 side) are monitoring means 19a, 19 respectively.
Communication is also performed in addition to b, and if the communication is normally performed, the operation on the monitoring side is temporarily skipped. That is, in step S1, the monitoring means 19b monitors the non-communication time to the basic management system 50.
If the non-communication time is equal to or less than the reference value, the process ends as it is.

On the other hand, when the non-communication time is equal to or longer than the reference value in step S1, a monitoring request is transmitted to the basic management system 50 (step S2). And
If the response is normal (step S3), it is determined whether the preliminary management system 60 is already being replaced (step S4), and if not being replaced, the non-communication time from the monitored side is cleared (step S4). S5), and ends. In step S4, if the preliminary management system 60 is being replaced, it is considered that the basic management system 50 has been restored normally, and a restart request is sent to the basic management system 50 (step S6). Clear (step S
7) and the process ends.

Further, in step S3, if the response from the monitored side is abnormal or there is no response, the monitoring request is retried. Then, if the retry is executed a prescribed number of times and it is abnormal, it is regarded as a fixed failure, and it is determined whether the spare management system 60 is in the process of replacement (step S
8). If it is in the process of substitution in step S8, the process ends, if it is not in the process of substitution, the basic management system 50 side is instructed to stop (step S9), and the management system identification means 14 of the own system is activated (step S10). Further, the in-substitution state is set (step S11). That is, the self-address is sent to the basic management system 50 to notify that the preliminary management system 60 manages the managed system 20.

Next, the monitoring means 1 of the basic management system 50
The operation of 9a will be described. FIG. 6 is a flowchart showing the operation. The basic management system 50 on the monitored side waits for a monitoring request, a restart request, or a stop request from the standby management system 60 on the monitoring side (step S1). Then, in the normal monitoring state (step S
2) If the monitoring request is received (step S3), the monitoring means 19a of the basic management system 50 sends a monitoring response (step S4). In step S3, if the request is a stop request, the process proceeds to step S5 to set the recovery monitoring state and waits for the next request.

On the other hand, in step S2, in the recovery monitoring state, when the restart request is received in this state (step S6), the normal monitoring state is set (step S7), and the management system identification means 14 is further activated ( Step S
8) The process moves to step S4 to restart communication with the monitoring side. If it is not the restart request in step S6, that is, if the monitoring request or the stop request is received in the recovery monitoring state, the process directly proceeds to step S4 and the monitoring response is transmitted.

Next, a third embodiment will be described. FIG. 7 is a configuration diagram thereof. This system is a mutual reserve system,
Each management system 70 that manages two networks
a and 70b monitor each other and perform substitution when the other party fails. That is, the management system 70a (indicated by M1 in the figure) is the management target system 2
0a-1 to 20a-n, and management system 70b
(Indicated by M2 in the figure) is the managed system 20b-1.
20b-n are managed.

The configuration of the management systems 70a and 70b is similar to that shown in FIG. 4, but each of the management systems 70a and 70b has the functions of both the preliminary management system 60 and the basic management system 50. ing. Further, also in the operation, both monitoring means 19a and 19b shown in FIGS. 5 and 6 can be operated. Therefore, in such a system, for example, when a failure occurs in the management system 70a, the management system 70b replaces the management system 70a as shown in FIG.
Continues to monitor whether or not it has been restored normally, and issues a restart request to the monitored side when restoration is detected.

Next, the fourth and fifth embodiments will be described. FIG. 8 shows a network configuration of (n + m) standby backup system 1, and n (indicated by M1 to Mn in the figure).
The basic management system 50 (50-1 to 50-n) is provided with m (indicated by S1 to Sm in the figure) preliminary management systems 60 (60-1 to 60-m). The basic management system 50-1 is the managed system 20a-1.
To 20a-n, the basic management system 50-2 manages the managed systems 20b-1 to 20b-n, and similarly, the basic management system 50-n manages the managed systems 20n-1 to 20n-1. It manages 20n-n.

In such a configuration, as a method for the preliminary management system 60 to monitor the basic management system 50,
A standby standby replacement system in which the order is determined in advance in the standby management system 60 and at the same time one active standby management system 60 monitors all the basic management systems 50, and each standby management system 60 is the entire management system. Fifty
There are two standby standby full monitoring methods for monitoring.

That is, the fourth embodiment is the standby preliminary replacement system, which will be described. First, the first spare management system (here, the spare management system 60-1) is in an active state and monitors all management systems 50.
If a failure of the first basic management system (here, the basic management system 50-1) is detected, replacement is performed. At this time, the first preliminary management system 60-1 notifies the second preliminary management system 60 that the substitution is started. After that, the second spare management system 60 becomes active, all the management systems 50 are monitored, and if a failure of the second management system 50 is detected, replacement is performed. At this time, 2
The third preliminary management system 60 notifies the third preliminary management system 60 that the substitution is started. In this way, the standby management system 60 in the active state is replaced in a predetermined order. Also, regarding the monitoring of the basic management system in failure (the basic management system 50-1 in the illustrated state), the method performed by the spare management system 60-1 being replaced, and the standby management system (60- 2-60-m) to monitor the entire basic management system 50.

Next, a fifth embodiment will be described. This fifth embodiment is a standby standby total monitoring system, in which each standby management system 60 first monitors all the basic management systems 50, and the standby management system 60 that has detected a failure is the other standby management system. The management system 60 is notified by the broadcast function, and one of the preliminary management systems 60 performs the replacement. Here, as a method of determining any of the preliminary management systems 60, a method of allocating the preliminary management system 60 closest to the basic management system 50 in which a regional (distance) failure has occurred, and There is a method to decide the order in.

For example, in FIG. 8, when a failure occurs in the basic management system 50-1, the preliminary management system closest to the basic management system 50-1 or the preliminary management system in a predetermined first order is preliminary managed. If it was system 60-1, this would do the replacement. afterwards,
The management of the basic management systems 50-2 to 50-n is performed by the preliminary management systems 60-2 to 60-m, and when a failure occurs from among these basic management systems 50-2 to 50-n, The same as the alternative operation of.

Next, a sixth embodiment will be described. FIG. 9 shows (n
+ M) shows a network configuration of standby standby system 2, in which n basic management systems 50 (50-1 to 50-)
m of the preliminary management systems 60 (60-1 to 60-1 to n)
60-m) is the same as the fourth and fifth embodiments. In addition, the managed system 20 (20a-1 to 20a-1
20n-n) and basic management system 50 (50-1 to 50)
The relationship with -n) is the same as in the fourth and fifth embodiments.

The difference from the above fourth and fifth embodiments is that the basic management system 50 (50-
1 to 50-n) are grouped according to region or network type, and the preliminary management system 60 (60-1 to 60-m) is assigned corresponding to the group. For example, in the illustrated example, the preliminary management system 60-1 is assigned to the basic management systems 50-1 to 50-10, and the basic management systems 50-11 to 50-20 are assigned.
The preliminary management system 60-2 is assigned to the group.

In such a configuration, each preliminary management system 60 has the basic management system 5 in the group.
0 is monitored, and when a failure of the basic management system 50 in the group is detected, its replacement is performed. For example, as shown in the figure, when a failure occurs in the basic management system 50-1,
The preliminary management system 60-1 performs the replacement. In addition, here, a replacement of the failed basic management system 50-1 and normal basic management systems 50-2 to 50 within the group are performed.
There is a method of performing both monitoring of -10 and a method of requesting monitoring of normal basic management systems 50-2 to 50-10 to other spare management systems 60-2 to 60-m. The method of requesting the management systems 60-2 to 60-m is shown.

Next, a seventh embodiment will be described. In the seventh embodiment, the basic management system 50 is monitored, and when any one of the basic management systems 50 fails, the basic management system 50 is replaced and the plurality of basic management systems 50 are monitored.

First, the monitoring means 19c acquires the addresses of the basic management system 50 and the preliminary management system 60 on the network (step S1). That is, in order to manage the basic management system 50 and the preliminary management system 60, each system is identified. Then
It is determined whether or not the non-communication time between the basic management system 50 and the preliminary management system 60 is a reference value or more (step S2),
When it is less than the reference value, the process directly proceeds to step S7, it is determined whether there is the next basic management system 50 or the preliminary management system 60, and if there is, the process returns to step S1 and if not, the process ends.

If the non-communication time is equal to or greater than the reference value in step S2, the basic management system 5
0 or a monitoring request is transmitted to the preliminary management system 60 (step S3), and it is determined whether the monitoring response of the basic management system 50 or the preliminary management system 60 is normal (step S4). In step S4, if the monitoring response is normal, it is determined whether the standby management system 60 is in the process of replacement (step S4).
5) If it is not being replaced, the non-communication time of the basic management system 50 or the preliminary management system 60 is cleared (step S6), and the process proceeds to step S7.

On the other hand, if it is determined in step S5 that the spare management system 60 is being replaced, it is determined whether the monitoring response is from the spare management system 60 (step S8). If it is not from the basic management system 50, it is determined that the basic management system 50 has recovered from the failure, and the standby management system 60 that is the substitute is instructed to stop (step S9), and Basic management system 50
