Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an asynchronous communication apparatus and system for asynchronously obtaining information on the operation state of an information device such as a computer or a network device connected to a network from another information device.

[0002]

2. Description of the Related Art As a method of communicating between computers,
Conventionally, there is a communication method using a socket. In this method, the program of the computer receiving the request always operates as a daemon, and when a request is received from another computer, a child process is created, and the child process receives the request from another computer. Therefore,
When a request is received from a plurality of computers at the same time, the child processes generate the number of requests and perform business processing. Also, the communication interface between the computers is not an interface such as a function interface, but just a communication message (character string), so the sending computer must create the communication message, and The computer must analyze the received communication message. Therefore, instead of the above message-type interface that is aware of the communication destination, RPC (Remote Procedure Call) that performs processing without being aware of the communication destination like a local function (subroutine) call
Was thought.

As an asynchronous communication means, SNMP (Simplified
There is a trap function of e Network Management Protocol). This is a protocol for managing computers, network connection devices, information devices, and the like in a multi-vendor network environment. In the SNMP, a management program called a manager is mounted on one computer on a network, and a program called an agent for communicating with the manager is mounted on a managed computer. When information is accessed between the manager and the agent, a method of specifying an object used to specify management information is used. Agents use traps to send information asynchronously to managers.

Further, in conventional network management in a multi-vendor environment, information devices such as workstations and computers and network connection devices such as bridges are managed using SNMP, but a Web browser (network browsing software), WWW (World Wide We
b) Server (network information providing / retrieval server software), distributed object platform technology, and Java
It did not use network monitoring (an environment centered on Sun Microsystems' object-oriented language).

[0005]

Conventionally, in order to perform asynchronous communication, a receiving program must be installed in a computer in advance. Therefore, information devices such as all computers connected to a network and network-connected devices are required. Was not always available.

In the case of a conventional communication program using a socket, a process for analyzing a communication message is required on the receiving side, so that the development of that part is necessary, which is one of the causes of the occurrence of program defects, and the development time It takes time. Also, RPC does not support object-oriented technology, so we cannot expect future development.

The W server 107, the object reference management table 108, and the applet program 109 are stored in a storage medium 110.

The distributed object platform 101 is an environment in which objects distributed in computers on a network execute processing in accordance with one flow as a whole while communicating with each other. This is a platform that can execute processing without being aware of the location of the program to be executed.
As the distributed object base 101, for example, OMG
(Object Management Group) CORBA (Co
mmon Object Request Broker Architecture) 2.0, J
RMI (Remote Method Inv) of ava (environment centered on Sun Microsystems' object oriented language)
ocation).

The interpreter 102 is an execution environment for a network-compatible object-oriented language.
This is a language execution environment suitable for processing in cooperation with a program between networks, such as a interpreter or other object-oriented languages such as conventional C ++ and Smalltalk. Here, a Java interpreter is used.

The WWW server 107 is software (network information / search service software) for releasing various information on a network and providing an information search service. Web browser 103
Is software (network browsing software) for accessing the WWW server 107 on the network to obtain information disclosed by the server 107 or to search for and search for desired information. The applet program 109 is a program developed in Java here. Computer 2 from another computer 1
When there is a download request via the Web browser 103, the applet program 109 is downloaded from the computer 2 to the computer 1, and executed as the applet 104 in the computer 1.

The communication program 106 is the computer 2
Is a program used for asynchronously communicating with the computer 1 (for example, when information about the operating state of the computer 2 is asynchronously transmitted from the computer 2 to the computer 1), and registered in the object reference management table 108. It communicates with the object. Storage media 105, 110

The applet program 109 is downloaded and executed on the interpreter 102 as the applet 104 (step 201).

When the applet has been downloaded, the distributed object infrastructure 101 is initialized (step 20).
2). If the initialization is successful, the applet 104 connects to the server object of the downloaded computer 2 (step 203). If the connection is successful, the object reference of the applet 104 itself, which is an object, is transmitted to the computer 2 (step 20).
4). Next, the applet 104 waits until a message is transmitted from the computer 2 (step 205), and upon receiving the message, displays the message (step 206). Then step 2
Returning to step 05, the process is repeated. Step 202
If each of the processes of to 204 fails, the process ends.

FIG. 3 and FIG. 4 are flowcharts showing a procedure performed by the computer 2 serving as a server in the system of FIG. The computer 2 first initializes the distributed object infrastructure 101 (Step 3)
01). If the initialization has failed, the process ends. If the initialization is successful, an object is generated (step 302), the generated object is put into a message receiving state (step 303), and a message reception wait is made (step 304). When an object reference is received from another computer (for example, computer 1), the object reference is registered in the object reference management table 108 (step 305). Thereafter, the process returns to step 304 to repeat the processing.

The object generated in step 302 performs the processing shown in FIG. First, it is determined whether there is a communication request to another computer (step 30).
7). For example, there is a case where a file is monitored, and when the description of the file is changed, the description of the file is to be notified to another computer. When such a communication request occurs, first, one object reference is extracted from the object reference management table 108 (step 309). If not, the process returns to step 308. If there is, a message is returned to the retrieved object reference (step 310). If this is successful, control returns to step 309 to retrieve the next object reference. If the message transmission fails in step 310, an object reference on the network is searched (step 311). If so, return to step 310.
If not, the object reference is deleted from the object reference management table 108, and the process returns to step 311.

As described above, in the first embodiment, the distributed object infrastructure technology, the Java language, and the We
Using a browser b, a receiving program (an applet program 109) described in the Java language is downloaded from the server (computer 2) to the client (computer 1) and executed, whereby the computer 2 is asynchronous with the computer 1 Since communication can be performed, the computer 1 can receive information transmitted asynchronously without installing a receiving program in advance. In addition, since there is no need to analyze received messages during development, the number of development steps is reduced, and program defects can be reduced.

In the above system, the computer 1
Although the example in which the computer and the computer 2 are connected to the network one by one has been described, the same processing may be performed when there are a plurality of computers.

For example, when a computer 1 and a plurality of computers 2 are connected to a network and information on the operating states of the plurality of computers 2 is desired to be obtained asynchronously by the computer 1, as described above, The computer 1 may execute the processing of FIG. 2 corresponding to each computer 2, and each computer 2 may execute the processing of FIGS. That is, in the computer 1,
A plurality of Web browsers are activated to connect to each computer 2, download an object from each computer 2, and transmit an object reference to each downloaded computer 2. In each computer 2, the object reference sent from the computer 1 is registered in a table, and when a communication request occurs, the object reference is extracted from the table and a message is sent. Note that it is also possible to perform asynchronous communication with a plurality of computers 2 on a network using one Web browser without activating a plurality of Web browsers.

When a plurality of computers 1 and computers 2 are connected to a network and information on the operating state of the computer 2 is to be obtained asynchronously by each of the plurality of computers 1, the same operation as described above is performed. In addition, the plurality of computers 1 may execute the processing of FIG. 2 on the computer 2 and the computer 2 may execute the processing of FIGS. That is, in each computer 1, network browsing software is activated, connected to the computer 2, downloads an object from the computer 2, and transmits an object reference to the downloaded computer 2. In the computer 2, the object references sent from the plurality of computers 1 are registered in a table, and when a communication request occurs, the process of extracting the object reference from the table and sending a message is performed on all the object references in the table. To do it.

Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a system configuration diagram according to the second embodiment of the present invention. A computer 41 and a computer 42 are connected to the network 100.
And the relay computer 43 are connected. In this figure, for the sake of simplicity, only one computer 41, one computer 42, and one relay computer 43 are connected to the network 100. However, in the actual embodiment, the computer 41 and the computer 42 are connected to the network 100. And a plurality of relay computers 43 are connected together. Note that the components numbered 400s in FIG. 5 correspond to the components with the same last two digits of the components numbered 100s in FIG. 1.
For example, the distributed object platform 401 in FIG. 5 is similar to the distributed object platform 101 in FIG.

The basic configuration of the second embodiment of FIG. 5 is the same as that of FIG. 1, but in the second embodiment, the computer 41 and the computer 42 do not need to directly communicate with each other. A relay computer 43 is provided. The relay computer 43 has the same configuration as the computer 2 in FIG. The computer 42 has a configuration in which the WWW server 107 and the applet program 109 in the computer 2 of FIG. 1 are deleted. The communication program 411 of the computer 42 is a program used by the computer 42 to asynchronously communicate with the relay computer 43. The object reference management table 412 (the object reference of the communication object by the relay program of the relay computer 43 is registered in advance. The communication is performed with respect to the object registered in).

FIG. 6 is a flowchart showing a procedure performed by the computer 41. The computer 41 first activates the Web browser 403, connects to another computer (here, the relay computer 43), downloads the applet program 409, and downloads the applet 4
04 and executed on the interpreter 402 (step 501).

After downloading the applet, the distributed object base 401 is initialized (step 50).
2). If the initialization is successful, the applet 404 connects to the server object of the downloaded relay computer 43 (step 503). If the connection is successful,
The applet 404 sends its own object reference to the relay computer 43 (step 504). Next, the applet 404 waits until a message is transmitted from the relay computer 43 (step 505), and upon receiving the message, displays the message (step 506). Then, step 50
Returning to step 5, the process is repeated. Steps 502-
If each process of 504 fails, the process ends.

FIGS. 7 and 8 are flow charts showing the procedure performed by the relay computer 43 in the system of FIG. The relay computer 43 first initializes the distributed object base 401 (step 601).
If the initialization has failed, the process ends. If the initialization is successful, an object is created (step 60).
2) Put the generated object in a message receiving state (step 603) and wait for a message to be received (step 604). When an object reference is received from another computer (for example, the computer 41), the object reference is registered in the object reference management table 408 (step 6).
05). Thereafter, the process returns to step 604 to repeat the processing.

The object generated in step 602 performs the processing shown in FIG. That is, it waits for a message to be received (step 606), and upon receiving the message, retrieves one object reference from the object reference management table 408 (step 60).
7). If not, the process returns to step 608. If there is, the received message is sent to the extracted object reference (step 609). If the message transmission is successful, the process returns to step 607 to retrieve the next object reference (step 61).
0). If the message transmission fails, an object reference is searched for on the network (step 61).
1). If so, return to step 612. If not, the object reference management table 408
The object reference is deleted from (step 613), and the process returns to step 610.

FIG. 9 is a flowchart showing a procedure performed by the computer 42 in the system shown in FIG.
The computer 42 first determines whether a communication request to another computer has occurred (step 70).
1). For example, there is a case where a file is monitored, and when the description of the file is changed, it is desired to notify the description of the file to another computer.
When such a communication request occurs, first, one object reference is extracted from the object reference management table 412 (step 703). This object reference is an object reference for calling a communication object of the relay computer 43 and is prepared in the object reference management table 412 in advance. That is, all communication objects of the relay computer 43 that send a message from the computer 42 when performing asynchronous communication from the computer 42 to another computer are registered in the object reference management table 412.

If there is no object reference in step 703, the process returns to step 702. If there is, a message is sent to the retrieved object reference (step 704). If this succeeds, the process loops until the next object reference can be retrieved (step 705). If the message transmission fails, an object reference on the network is searched (step 706). If there is, the process returns to step 707.
If not, the object reference is deleted from the object reference management table 412 (step 708), and the process returns to step 705.

As described above, in the second embodiment, the distributed object infrastructure technology, the Java language, and the Web
Using a b browser, a receiving program (an applet program 409) described in Java language is downloaded from the relay computer 43 to the computer 41 and executed. The computer 41 transmits an object reference to the relay computer 43, and
Then, the object reference is registered in the table 408, and when communicating asynchronously from the computer 42, a message is sent from the computer 42 to the communication object of the relay computer 43, and the received message is transmitted to the relay computer 43 by the object reference management table. 408 to the retrieved object reference. Thereby, communication can be performed asynchronously between the computer 42 and the relay computer 43, and further, communication can be performed asynchronously between the relay computer 43 and the computer 41. As a result, the computer 41 And 42 can be communicated asynchronously. The computer 4
The same processing may be performed even when a plurality of 1, the computer 42, and the relay computer 43 are connected to the network.

[0041]

According to the present invention, a communication object (for example, a receiving program described in the Java language) is downloaded and executed by using the distributed object infrastructure technology and the network browsing software. Since the program can be executed without occupation, the computer connected to the network can perform processing without installing the receiving program in advance. In addition, since there is no need to analyze received messages during development, the number of development steps is reduced, and program defects can be reduced. Further, it is possible to perform asynchronous communication with a computer on a network by using one network browsing software without activating a plurality of network browsing software.
