In the present invention, each communication-dedicated virtual operating system that controls communication between each AP and has both an internal task and external / user process information so that communication between the virtual operating systems can be performed according to the control of the operating system, Dedicated virtual operating system means; And an external and user process for performing communication with another AP through a message queue in the communication-dedicated virtual operating system means under the control of the communication-dedicated virtual operating system means.

Description

Unix (UNIX) system communication-only virtual OS implementation device

Generally, a communication-specific virtual operating system (COVOS) is a program that controls various communication programs executed on a branch processor, which is a bank device, and provides functions.

This COVOS does not work on Unix systems, but only on PCs.

FIG. 1 is a layout diagram of communication programs under the conventional OS, in which a plurality of COVOSs 2a-2n exist under the operating system 1 and APs 3a-3n operate under the COVOSs, respectively .

Here, one COVOS is composed of an external processor 3a-1, an internal task 3a-2, and a user process 3a-3 according to the nature of the lower AP, as shown in FIG.

The above-mentioned internal task 3a-2 is a single process because each task takes a communication method having the same nature.

The other external processes 3a-1 and user processes 3a-3 perform work by receiving only a limited user library provided by COVOS, a communication-only virtual operating system.

That is, from the viewpoint of the system operating system (OS), only the communication-dedicated virtual operating system (COVOS) including the internal task part and the external and user processors are recognized as processes.

The difference between the external process 3a-1 and the user process 3a-3 and the COVOS internal task 3a-2 has been mentioned for a while, but the biggest difference is that COVOS is slightly And the COVOS internal task controls and controls all of the tasks and controls all necessary functions.

In the case of external and user processes, COVOS requests the COVOS internal task for communication, but the COVOS communicates instead.

3 shows a block diagram of a system capable of communicating with a plurality of COVOSs. The COVOS management process 5 exists under one operating system 4. Under the COVOS management process 5, a plurality of COVOSs 6a- 6n are connected and operated.

However, in such a conventional system, since several COVOSs exist under one OS, communication between the APs under COVOS is difficult. This is because communication between an AP under COVOS1 and an AP under COVOS2 is a burden for another communication.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a communication-only virtual operating system And to provide an apparatus for implementing a communication-only virtual operating system of a UNIX system.

As mentioned in the prior art, in order to enable communication between multiple COVOS, it is necessary to integrate several COVOS into one COVOS as in the fourth method. In addition, among many existing internal tasks, the independence of the user process makes the existing COVOS provided library (LIBRARY) stronger and independent to the user process. In addition, COVOS further enhances the loose control over the existing user process, so that even if the AP that was the internal task becomes the user process, there is no modification of the CODING.

In order to accomplish the object of the present invention, each communication-dedicated virtual operating system is provided with information on an internal task and internal / external processes, And an external and user process for performing communication with another AP through a message queue in the communication-dedicated virtual operating system means in accordance with the control of the communication-dedicated virtual operating system means.

FIG. 4 is a block diagram of an apparatus for implementing a communication-only virtual operating system of a UNIX system according to the present invention.

As shown in the figure, in order to enable communications between the operating systems 10 and the communication virtual private operating systems under the control of the operating system 10, A virtual private network operating system unit 20 in which each virtual private operating system is merged; An external and user process (40) (50) for performing communication with another AP through a message queue (22) in the communication-dedicated virtual operating system unit (20) under the control of the communication-dedicated virtual operating system unit (20); And an internal task unit 30.

The operation of the apparatus for realizing the communication-dedicated virtual operating system of the UNIX system according to the present invention will be described below.

First, the communication-dedicated virtual operating system 20 existing under the operating system 10 has all the information about the external task and the user process as well as the internal task, and is responsible for communication between the APs.

Here, the communication between APs is performed as in the fifth aspect.

That is, since the device for implementing a communication-only virtual OS is configured under a UNIX OS environment, the basic communication is designed using Interprocess Communication (IPC) provided in Unix.

In other words, the user and the external processes 50 and 40 create their own message queues and register them in COVOS for communication with other APs.

Then, the message is transmitted to the partner AP to communicate with. At this time, the message is not sent directly to the AP, but is transmitted to the message queue 22 of the COVOS 20, which is a communication-only virtual operating system.

The COVOS 20 judges to which AP this message should be sent and then transmits it to the corresponding AP.

In this way, the COVOS 20 manages the external and user processes 40 and 50.

On the other hand, in the case of an internal task, the COVOS 20 sends a message to the internal task control unit 21 in the COVOS 20, and transmits the message to the corresponding AP to perform communication.

INDUSTRIAL APPLICABILITY As described above, the present invention has the effect of realizing a communication-only virtual operating system that is further enhanced by improving the control and management functions for the AP operating under COVOS.

In addition, COVOS can be used not only in UNIX operating systems but also in other operating systems by improving the function of communication-only virtual operating system (COVOS).
