Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for managing a computer network such as the Internet by coordinating a plurality of network management systems, a network management synchronization system for implementing the method, and a network cooperative management program. It relates to a recording medium.

[0002]

2. Description of the Related Art When managing a computer network such as the Internet, a network management system (NMS) is used. FIG. 4 shows a state of management by the existing network management system.

[0003] Network equipment uses MIB (M) as information on its parameters and status (called management information).
An SNMP (Simple Network Management Prot.)
ocol) is used to provide access (set and change of MIB).

[0004] SNMP has a simple trap and polling management model. Polling is an NMS
Is an operation of acquiring necessary information from a network device. Conversely, a trap is sent to an NMS to notify a network device when a predetermined condition (for example, a link is broken) is satisfied.

[0005] The NMS collects management information from network devices using the mechanism of SNMP. Also, N
Some MSs have a mechanism to call attention according to the state of polled management information (called an event). The network administrator analyzes the traps and events received by the NMS and responds as necessary. Depending on the result, traps and event data held by the NMS are deleted or marked.

[0006]

There are cases where a plurality of management organizations must manage the same network (or a part thereof). For example, there is a case where network management is outsourced, but the requester responds in an emergency. The NMS is installed at both the outsourcing destination / source and manages the same area. in this case,
The functions and settings of each NMS do not always match.
This is because their roles, equipment, skills and policies are different.

However, the existing NMSs are assumed to operate individually as shown in FIG. 5, for example. Therefore, it is not possible to grasp how far other organizations have dealt with the sent traps, resulting in inefficient problems such as duplication of the measures and yielding. In addition, since the definition of the management information can be changed by each NMS arbitrarily, there arises a problem that hinders mutual information exchange and the like.

[0008] The present invention has been made in view of the above points, and an object of the present invention is to manage a computer network using a plurality of NMSs and to determine the status of measures taken on a specific NMS. It is an object of the present invention to provide a network cooperative management method for performing efficient management by reflecting on an NMS, a network management synchronization system for realizing the method, and a recording medium on which a program for the method is recorded.

[0009]

According to the present invention, when a computer network is managed using a plurality of network management systems (NMS), management information sent from each network device (managed object) to a plurality of NMSs is provided. Records of actions taken on a specific NMS are reflected on other NMSs, and management information (MIB) provided by each NMS
By providing means for matching the definition files described above, a plurality of NMSs are used to manage the network in cooperation without duplication of work. The means for managing the computer network in cooperation with the plurality of NMSs without duplication of work will be referred to herein as a cooperative management platform.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a conceptual diagram of network cooperative management and network management synchronization according to the present invention. In the figure, 10 is a network management system (NMS), 20 is each a network device, 1
00 is a cooperative management platform.

The cooperative management platform 100 operates on a computer network as follows. The NMS 10 constantly collects the status of coping with traps and events. Aggregate the collected response status. The totaled result is reflected in data that records the status of response to traps and events of each NMS. The definition of the management information is acquired from each NMS, and it is checked whether they match each other. The definition of management information between NMSs is matched to a specific NMS.

As described above, when a network is managed using a plurality of NMSs, the status of handling traps and events performed by each NMS is reflected on other NMSs, so that duplication of work in each NMS is eliminated. , Work can be streamlined. Further, when the definition of the management information is updated by a certain NMS, it can be detected and updated by another NMS.

FIG. 2 shows a collaborative management platform 100.
FIG. 7 is a diagram showing a state of processing in FIG. As in FIG. 1, the network is managed using M NMSs (1 to m) 10. Each NMS 10 has management information definition 11 and trap handling status data 12.

The cooperative management platform 100 receives a trap from a network device and
To the global trap DB 12
Store to 0. The global trap DB 120 has a field for recording, as an attribute, a coping situation in each NMS 10 for each trap.

In the cooperative management platform 100, an agent 110 monitoring each NMS 10 operates as follows.

In a certain NMS 10, when data (trap response status data) storing the response status (accepted, erased, etc.) of the trap is updated, the result is stored in the response status field of the global trap DB 120. reflect.

An administrator of a certain NMS 10 sends a synchronous request for trap handling status to the cooperative management platform 1.
00 can be issued. In this case, the NM
The agent 110 monitoring S10 uses the handling status of each NMS 10 in the global trap DB 120 and updates the trap handling status data 12 of the NMS based on the trap synchronization rule. The trap synchronization rule describes a method of counting the handling status in the global trap DB 120. For example, a trap that has been handled (consigned / erased) by one NMS is set to the same handling status in another NMS.

The management information definition 11 of the NMS 10 is monitored, and when it is changed, a change notification of the management information definition is generated to another NMS 10.

Next, an operation example of the network cooperative management and network management synchronization of the present invention will be described with reference to FIG.
FIG. 3 shows that network devices 20-1 and 20-2 and 20-3 and 10-4 are installed in a network operation center (NOC) located in Tokyo and the west coast of the United States, respectively. 1 to
10-4 is managed alternately day and night. Each NOC has NMS 10-1, 1 respectively.
0-2 is installed and the cooperative management platform 100
Is installed in each NOC. SNMP traps from the network devices 20-1 to 20-4 are set to be sent to the cooperative management platform 100.

NMS1 for both Tokyo and US West Coast NOC
0-1 and 10-2 are switched day and night by network device 20-
1 to 20-4, and each has a management information definition file and trap handling status data.

Now, assume that a new type of network device 10-5 is added to the Tokyo NOC. Management information for it (M
IB) Set the definition file in NMS 10-1 of Tokyo NOC. The collaborative management platform 100 is an NMS 10-
1 that the definition file has been changed,
Notify S10-2. Each network device, when there is a state change,
The MP trap is sent to the cooperative management platform 100. The collaborative management platform 100 uses both NMs.
The trap is transferred to S10-1 and 10-2. Now, at the Tokyo NOC, the administrator
Investigate the cause by looking at the SNMP trap received by
Make sure you do n’t need to worry, accept the trap,
Let's say you erased it. When it is time to manage at the US West Coast NOC, the manager looks at NMS 10-2 and knows that the MIB file has changed. Then, when the synchronization of the MIB definition is instructed, the network device 2 added at the Tokyo NOC is
MIB definition file for 0-5 is US West Coast NOC
Is also read by the NMS 10-2. Furthermore, if the NMS of the US West Coast NOC instructs the synchronization of trap event handling, the Tokyo NOC
To reflect the result of erasure or commission. The West Coast NOC will address any remaining unresolved traps and what will follow.

Although the embodiment of the present invention has been described above, the processing algorithm of the cooperative management platform described with reference to FIGS. 1 to 3 uses a computer disk (FD), a memory card, and a compact disk as a network cooperative management program. (CD0ROM) or the like.

[0023]

As described above, according to the present invention,
In the case where a plurality of organizations manage computer networks using NMSs, it has not been possible to grasp how far each other has dealt with each other, and problems such as inefficiencies such as duplication of duties and concessions occur are improved. Also, N
It is expected that troubles caused by the inconsistency of the definition of the management information between the MSs and troublesome work for matching the troubles can be reduced.
