DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network resource management system for managing resources held by computers connected via a network, and is applicable to, for example, a client-server model distributed system.

[0002]

2. Description of the Related Art Document 1: "Shunji Sugawara," Application of Multi-agent to Internetwork Management ", Artificial Intelligence Society Meeting, SIG-FAI-9502-7 (9/19), pp37-38" Article 2 : "Eiichi Osawa," Negotiation Model in Multi-Agent Environment ", Journal of the Japanese Society for Artificial Intelligence, Vol.10, No.5, pp690
-696, Sept. 1995] Computers such as general-purpose computers, workstations, and personal computers are connected via a network, and the network management method for a distributed system in which the resources held by each computer are shared with each other has conventionally been described above. There is a method according to a multi-agent system as described in Reference 1 or Reference 2.

According to this method, agents distributed on a network autonomously collect information flowing on the network, and manage resources on the network based on the collected information (monitoring, failure diagnosis, etc.). It is to do.

[0004] When a plurality of agents arranged in a distributed manner cooperate to reach an agreement, each agent changes a cost for changing from a target owned by the agent to another target by a predetermined cost. Calculate the value of the goal that you have from the function and also calculate the final goal so that the total cost increase and the loss of the total value of all the agents that need to agree are minimized. Was.

[0005]

However, the above-described resource management method has the following problems.

That is, since agents to be distributed and arranged on a network are fixedly installed at a certain position, it is necessary to determine the most effective position for installing the agent. There was a problem that it was difficult to decide.

[0007] Further, in cooperation among a plurality of agents, the cost required for a goal change needs to be uniquely determined by a cost function, that is, it must be clearly and numerically determined. It is difficult to determine an appropriate numerical value.

Further, the value of the goal of each agent is
There is a problem that it is necessary to clearly give numerical values, and it is difficult to give such appropriate numerical values.

Therefore, there has been a demand for a network resource management system which does not require the determination of the installation position and the numerical expression of cost and value.

[0010]

According to the present invention, there is provided a network resource for managing a plurality of resources existing in a network comprising a plurality of computers based on a management request command issued by a management request unit. In the management system, the following was done.

That is, (1) each of a part of the computers, based on the management request command issued by the management request means,
A resource management agent having resource name information to be managed and management operation information is generated for each resource type, and the generated resource management agent is provided to a network. On the other hand, when a resource management agent into which management result information is inserted is provided. And agent management means for providing the manager with the inserted management result information and responding to the manager. (2) Some or all of the computers each have an agent processing means, and the agent processing means is provided to the network. If a resource management agent is received, and a resource for the resource name information included in the received resource management agent is under the management of the own computer, the resource is managed based on the management operation information included in the resource management agent; The management result information is inserted into the resource management agent, The above-mentioned resource management agent is given to the above-mentioned agent processing means of another computer which has not visited, and when there is no above-mentioned agent processing means of another computer which has not visited, the above-mentioned resource management agent is generated by the above-mentioned agent Give to the means.

Further, the agent control processing means, when there are a plurality of accepted resource management agents,
A priority determining unit that determines the priority of the resource management agent received based on a predetermined rule;

In the present invention, (1) some computers respectively generate resource management agents for each resource type based on the management request command issued by the management request means and give the resource management agents to the network; When the inserted resource management agent is given, the inserted management result information is given to the manager and responds. (2) Some or all of the computers are assigned resources based on the resource management agent provided to the network. If it is under the control of its own computer, it manages this resource based on the resource management agent, inserts the management result information into the resource management agent, and sends it to other computers not visiting the resource management agent. When there is no other computer that has not been visited, it is given to the originating computer, Fixedly no longer be installed, i.e., there is no need to determine the installation position of the agent.

When there are a plurality of accepted resource management agents, the priority of the accepted resource management agents is determined based on a predetermined rule, thereby numerically expressing the cost and value of each resource management agent. Eliminates the need.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (A) First Embodiment Hereinafter, a network resource management system according to the present invention will be described.
A first embodiment realized by a distributed system of a client-server model will be described in detail with reference to the drawings. Here, FIG. 1 is a block diagram showing a functional configuration of the first embodiment, FIG. 2 is a block diagram showing a physical network configuration thereof, and FIG. 3 is a flowchart for explaining its operation. is there.

In FIG. 1, a network resource management system according to the first embodiment includes a client 1-1,
It has a configuration in which a proxy server 1-2, primary servers 1-3 to 1-5, and secondary servers 1-6 to 1-8 are provided.

The client 1-1 issues a resource management request for monitoring and operating network resources.

Resource management agent general control section 1-9
Corresponds to a resource management request issued by the client 1-1 (for example, 1-1 shown in FIG. 1).
6 to 1-20) to control the destination of the issued resource management agent and the cooperation between the resource management agents.

The proxy server 1-2 runs on a computer connected to the network, and has such a resource management agent general control unit 1-9.

Resource management agent control unit 1-10-1
Reference numeral -12 is for accepting the issued resource management agent and controlling the resource management performed by the accepted resource management agent, cooperation between the resource management agents, and the destination of the resource management agent.

The primary servers 1-3 to 1-5 operate on computers connected to a network, and have such resource management agents 1-10 to 1-12.

Resource object manager 1-13 to 1-1
Reference numeral 5 denotes a resource object such as a resource object obtained by converting a CPU resource of a computer into an object, a resource object of a printer, a resource object of a user using the computer, and a resource object obtained by converting resources on each network such as TCP packets. It manages objects (for example, 1a, 1b, 2a, 3a to 3c shown in FIG. 1).

The secondary servers 1-6 to 1-8 run on computers connected to the network together with the primary servers 1-3 to 1-5. Such a resource object management unit 1-13 ~ 1-15.

The network resource management system according to the first embodiment has a physical network configuration as shown in FIG.

In FIG. 2, between networks 0 to 3,
They are connected by routers (or gateways) 2-9 to 2-11. In addition, on each network, a computer 2
Network resources such as -1 to 2-7 and a printer 2-8 are connected.

A client that issues a network resource management request exists on a computer connected to the network. The number of clients existing on one computer, the number of clients existing on one network, and the number of clients existing on the entire network are not limited.

A proxy server for receiving a resource management request issued by a client also exists on a computer connected to a network. In principle, it is preferable that one proxy server exists on one network, but if there is no proxy server depending on the proxy server that exists on another network, or if there are multiple proxy servers on one network May be present.

Further, the primary server which performs control based on the resource management agent from the proxy server, and the secondary server which is the location of the resource object and which manages the resource object, both exist on computers connected to the network. And exists at a uniquely determined position on the network such as an IP address space.

Further, a plurality of resource management agents can exist at each position where the primary server exists, and the position can be moved to another primary server. On the other hand, a plurality of resource objects can exist at each position where the secondary server exists.

Next, the operation of the network resource management system according to the first embodiment will be described in detail with reference to the flowchart of FIG.

The client 1-1 issues a network resource management request to the designated proxy server 1-2 (step 3-1). The client 1-1 issues this request using a general tool such as a browser of the World Wide Web. Also,
This request includes the name of the resource to be managed and the content of the management operation, and it is assumed that a plurality of resource names can be specified.

The proxy server 1-2 has a client 1-1.
Receives the resource management request issued by. This proxy server 1
-2 also uses a general tool like the client 1-1. For example, World Wide W
HyperText Transfer used by eb
It uses a general communication procedure such as rProtocol.

The proxy server 1 receiving the resource management request
2 analyzes the contents of the resource management request (step 3-
2) In the resource management agent general control unit 1-9, one resource management agent is issued for one resource name included in the resource management request (step 3).
3). That is, when a plurality of resource names are included in the management request, a plurality of resource managements are issued.

The resource management agent issued from the proxy server 1-2 is, for example, as shown at 1-16 to 1-20 in FIG.
The server moves to one of the primary servers 1-3 to 1-5 having the server 12 (step 3-4). Here, an example in which the user first moves to the primary server 1-3 will be described below. The resource management agent includes a resource management agent control unit 1-1.
From 0, a standby state is set until the execution of the management operation is permitted (no in step 3-5). When the execution of the management operation is permitted by the resource management agent control unit 1-10 (yes in step 3-5), the client 1-1
Requests the resource object management unit 1-13 of the secondary server 1-6 to execute a management operation on the resource object corresponding to the resource name requested by the user (step 3-6).

The resource object management section 1-13 checks whether or not a resource object to be managed is present on the secondary server.
7) The management operation is executed (step 3-8),
The execution result is returned to the resource management agent. If it does not exist (no in step 3-7), an error is returned to the resource management agent.

Next, if there is a primary server that has not been visited yet (Yes in step 3-9), the resource management agent moves to the primary server. In this case,
It will move to one of the primary servers 1-4 or 1-5. Similarly, in the destination primary server, when permission to execute the management operation is obtained, the management operation is requested to the resource object management unit. If the resource object to be managed exists in the resource object management unit, the management is performed. Perform the operation and respond with the result of the operation, and if it does not exist, respond with an error, and move to a primary server that has not been visited.

As a result, when there are no primary servers that have not been visited (no in step 3-9), the resource management agent 1 issues a resource management agent general control unit 1.
Return to proxy server 1-2 having -9 (step 3-1)
0).

The proxy server 1-2 responds by outputting the execution result brought back by the resource management agent to the client 1-1 (step 3-11).

As described above, according to the first embodiment, a resource management agent is issued for each resource in response to a resource management request from a client, and each resource management agent moves to one resource to be managed. , The client can manage the network resources without knowing the location of the resources to be managed.

Further, according to the first embodiment, since each resource management agent moves and executes a management operation, the client can execute a single resource management request on resources existing at a plurality of locations. To perform administrative operations.

Further, according to the first embodiment, since a general protocol is used for communication between the client and the proxy server, it is not necessary to provide a new means on the client side.

(B) Second Embodiment Hereinafter, a network resource management system according to the present invention will be described.
A second embodiment realized by a client-server model distributed system will be described in detail with reference to the drawings. Here, FIGS. 4 and 5 are block diagrams showing a detailed configuration of each part of the second embodiment, and FIG. 6 is a flowchart for explaining the operation.

Although not shown, the second embodiment also has a configuration similar to that of the first embodiment. However, in the second embodiment, the resource management agent control unit provided in the proxy server and the primary server has a more detailed additional configuration. Therefore, hereinafter, the detailed configuration of the resource management agent control unit will be described in detail.

FIG. 4 is a block diagram showing a detailed configuration of the resource management agent control unit in the second embodiment. In FIG. 4, a primary server (or a proxy server) 4
-1 resource management agent control unit 4-2
Moves the resource management agent to another primary server, an agent generation unit 4-5 that generates a resource management agent, an agent storage unit 4-6 that stores the generated resource management agent and the visited resource management agent. Agent movement control unit 4-7, an agent reception control unit 4-8 for receiving a resource management agent from another primary server, and a synchronization control unit 4 for controlling the execution order when a plurality of resource management agents are present. -9, a resource management operation storage unit 4-10 for temporarily storing the resource name, operation content, and execution result of the executed resource management agent, and a resource object for executing the resource management operation based on the executable resource management agent. A resource management operation requesting unit 4-11 for requesting the management unit is provided.

FIG. 5 is a block diagram of the synchronization control unit 4-
9 is a block diagram showing a detailed configuration of No. 9; FIG. In FIG.
The synchronization control unit 4-9 includes an agent standby unit 5-2 that waits until the resource management agent becomes executable, and an inference unit 5-3 that infers the priority of the resource management agent.
And an executable agent determining unit 5-4 for determining an executable resource management agent based on the inference result.

Next, the operation of the resource management agent control unit in the second embodiment will be described in detail with reference to the flowchart of FIG.

In the agent generation unit 4-5, when the client issues a resource management request or as a result of executing a resource management operation in the secondary server, it is found that a resource following the specified resource name exists. In such a case, a resource management agent for performing the resource management operation is created (step 6-1). Note that one resource management agent is generated for each resource name.

When the resource management agent is generated in the agent generation unit 4-5, the agent storage unit 4
At -6, the generated record is stored (step 6-2). Also, the generated resource management agent,
It moves to another primary server specified by the agent movement control unit 4-7 (step 6-3).

The resource management agent that has moved to the intended primary server is received by the agent reception control unit 4-8 of the primary server. Here, if there is already a visit record or a record of generation of this resource management agent in the agent storage unit 4-6 (no in step 6-4)
Side), the information is not stored in the agent storage unit 4-6,
Acceptance of this resource management agent is rejected. If there is no visit record or generation record of the resource management agent (yes in step 6-4), the received visit record of the resource management agent is stored in the agent recording unit 4-6, and The management agent is provided to the synchronization control unit 4-9 (step 6-
5).

In the synchronization control unit 4-9, the resource name and the operation content to be executed by the given resource management agent are queued in a queue in the agent waiting unit 5-2 (step 6-6). . The inference unit 5-3 infers the priority of executing the resource management agent in accordance with the names of the resources queued in the queue and the contents of the operation (step 6-7). The execution order of the management agents is rearranged (step 6-8).

Here, the executable agent determining unit 5-
In step 4, if there is an active resource management agent, that is, if it is not executable (step 6-
9), no management operation is performed. Of course, here
When a new resource management agent is given, it will be further reorganized. If it is confirmed that there is no resource management agent in execution (yes in step 6-9), the resource management agent having the highest priority is determined to be executable, and the executable resource management agent is determined to be executable. It is given to the resource management operation requesting unit 4-11.

In the resource management operation requesting unit 4-11, a resource management operation is requested to the resource object management unit in the secondary server based on the given resource management agent (step 6-10). The requested resource management operation is executed by the department. When the resource object management unit obtains a result based on the execution of the resource management operation, the obtained operation execution result is provided to the primary server.

The operation execution result given to the primary server is stored in the management operation result storage unit of the resource management agent (step 6-11), and is also stored in the resource management operation storage unit 4-10 (step). 6-12).

Here, when the resource management operation storage unit 4-10 stores the operation execution result, the resource management operation requesting unit 4-11 requests again the same operation content for the same resource name. Without making such a request, the stored operation execution result is given to the resource management agent, and the processing of the resource object management unit can be reduced. In addition,
The operation execution result stored in the resource management operation storage unit 4-10 is a temporary result deleted after a predetermined time.

The resource management agent receiving the management operation execution result, if there is an unvisited primary server (step 6-13yes side), the agent movement control unit 4
Move to another primary server indicated by -7. If there is no unvisited primary server (No in step 6-13)
Side), moves to the proxy server (step 6-14), and gives the operation execution result to the client.

As described above, according to the second embodiment, the same effects as those of the first embodiment can be obtained, and further, the following effects can be obtained.

That is, according to the second embodiment,
As a result of executing a resource management operation, an agent generation unit that generates a resource management agent is provided even if a resource following the specified resource name exists, so it became necessary from the execution result of the resource management request from the client. The resource management agent can be issued, and the resource management request issued by the client is not lost.

Further, according to the second embodiment, since the agent movement control unit for instructing the destination of the resource management agent is provided, the resource management agent does not need to have information such as a destination list. The information amount of the management agent can be reduced.

Further, according to the second embodiment, since the agent reception control unit for determining whether or not the visited resource management agent is accepted is provided, the same resource management agent does not return.

Furthermore, according to the second embodiment, when a plurality of resource management agents are present, a synchronization control unit for determining the priority order is provided, so that a plurality of resource operations are not performed at the same time. At the same time, resource operations can be executed with priorities.

Further, according to the second embodiment, the resource management operation storage unit for storing the resource name, the operation content, and the execution result of the executed resource management agent for a predetermined time is provided. Will not be executed repeatedly.

(C) Third Embodiment Hereinafter, a network resource management system according to the present invention will be described.
A third embodiment implemented by a client-server model distributed system will be described in detail with reference to the drawings. Here, FIG. 7 is a block diagram showing a detailed configuration of each part of the third embodiment, FIG. 8 is a flowchart for explaining the operation, and FIGS. 9 to 11 explain a method for inferring the priority. FIG.

Although not shown, the third embodiment has a configuration similar to that of the second embodiment. However, in the third embodiment, the inference unit in the synchronization control unit has a more detailed additional configuration. Therefore, the detailed configuration of the inference unit will be described below.

FIG. 7 is a block diagram showing a detailed configuration of the inference unit. In FIG. 7, the inference unit 7-1 according to the third embodiment makes a rule for an inference method of the priority order based on the operation content and the operation waiting time for the resource name that the resource management agent is about to execute. An inference rule unit 7-2 for performing the following, and a priority order determination unit for reorganizing the priorities of the resource names and operation contents queued in the agent standby unit according to the inference result from the inference rule unit 7-2. Is provided.

Next, the operation of the inference unit in the network resource management method and apparatus of the third embodiment will be described in detail with reference to the flowchart of FIG.

The priority order determination unit 7-3 creates an order table in which the operation standby time and the priority are added to the resource names and operation contents queued in the agent standby unit (step 8-1). Here, the newly queued one has the operation standby time of 0 and the lowest priority added.

In the inference rule section, inference is performed by a rule-based inference method. Hereinafter, the inference method will be described with reference to FIGS.

For example, regarding the operation contents, if the operation contents are information acquisition operations, then the priority is slightly lowered. If the operation contents are information setting operations, then the priority is greatly increased. Is short, then the priority is not changed. If the operation wait time is quite long, then the priority is greatly increased. The degree is expressed by a function as shown in FIG.
Here, FIG. 9A is a function expression relating to the operation content, and FIG. 9B is a function expression relating to the operation standby time. The function shown in FIG. 9 is an example, and can be changed according to a network environment or the like.

Here, the inference method will be described by taking as an example a case where the operation content is an information acquisition operation and the operation standby time is t shown in FIG. 9B. First, since the operation content is an information acquisition operation, the function NM of FIG. 9A is applied, and the degree of priority is the entire area of the function NM (step 8-2). On the other hand, since the operation standby time is t, the functions ZR and PM in FIG. 9B are applied, and the degree of priority is a hatched portion as shown in FIG. 10 (step 8-3). Here, the hatching unit 10-1 indicates the priority when the function ZR is applied, and the hatching unit 10-2 indicates the priority when the function PM is applied.

FIG. 11 summarizes the degrees of priority expressed in this manner. The hatched portions 11-1 and 11-2 correspond to the hatched portions 10 in FIG.
-1 and 10-2, and the hatched portion 1
1-3 shows the degree of priority of the function NM in FIG. 7A due to the fact that the operation content is an information acquisition operation. From this result, the center position of the portion indicating the degree of priority is calculated, and the priority is inferred (step 8-).
4).

In the priority order determining unit 7-3, the order of the resource name and the operation content in the agent standby unit is reconfigured based on the inferred priority order (step 8-5).

As described above, according to the third embodiment, the same effects as those of the second embodiment can be obtained, and further, the following effects can be obtained.

That is, according to the third embodiment,
Since the degree of priority regarding the operation content and the degree of priority regarding the operation standby time are expressed by a function, and the priority is determined from the sum thereof, it is not necessary to numerically express the target value of the resource management agent.

Further, according to the third embodiment, since the operation content is included in the element for determining the priority order, it is possible to realize the resource management work corresponding to the speed of the operation content.

(D) Other Embodiments In each of the above embodiments, a case has been described in which the present invention is applied to a distributed system of a client-server model. However, the present invention is applied to a case where a plurality of computers are connected via a network. The same applies to the case where the present invention is applied to the system.

[0076]

As described above, according to the present invention, some computers each have a resource having management target resource name information and management operation information based on the management request command issued by the management request means. Create management agents for each resource type,
The generated resource management agent is provided to the network. On the other hand, when the resource management agent into which the management result information is inserted is provided, the resource management agent has agent management means for providing the manager with the inserted management result information and responding. Each of the units or all of the computers includes an agent processing unit. The agent processing unit receives a resource management agent provided to the network, and a resource corresponding to the resource name information included in the received resource management agent is managed by the own computer. If the resource management agent exists in the resource management agent, the resource management agent manages this resource based on the management operation information contained in the resource management agent, inserts the management result information into the resource management agent, and does not visit the resource management agent. Given to the agent processing means of the computer and visited When there is no agent processing means of another computer which does not have the above, since such a resource management agent is given to the agent management means of the generation source, the agent is not fixedly installed, that is, the agent is not installed. It is no longer necessary to determine the installation position of the device.

Further, if there are a plurality of accepted resource management agents,
Since there is a priority determining unit that determines the priority of the resource management agent received based on a predetermined rule, it is not necessary to numerically express the cost and value of each agent.
