[Industrial Field of Application] The present invention relates to a communication control adapter that supports a plurality of communication lines and hierarchical communication procedures, or a communication control procedure management method in a communication control device.

With recent advances in data communication technology, hierarchical communication procedures have become commonplace, and a plurality of communication procedures have come to be defined for each layer.

FIG. 4 is a diagram showing an example of the layering of recent communication procedures, in which the network layer determines which communication network (for example, telephone 'M4/data network/-, The data link layer is a layer that determines which line (data link) of each communication network layer to use, and the physical layer is a layer that determines the physical connection procedure for bit transmission. In addition to this, there are also upper layers such as a transport layer.

Furthermore, the independence of each layer from other layers is further strengthened, allowing the necessary layers to be prepared when necessary, the communication procedures for each prepared layer to be selected, and the combinations to be applied to each communication partner. It is thought that the number of operational formats that will be changed will increase in the future.

FIG. 5 is a diagram showing an example of a combination of communication procedures in each layer, and the communication procedures in each layer differ depending on the communication partner (a, b, '-.X).

Furthermore, recent improvements in hardware technology have improved the capabilities of communication control adapters or communication control devices, and it has become common for one adapter to support multiple hierarchies. 'Under these circumstances, communication control procedure adapters are now required to have a communication procedure management system that allows the combination of communication procedures used in each layer to be changed on a line-by-line basis.

[Prior art and problems to be solved by the invention] FIG. 6 is a diagram illustrating a communication procedure management system in a conventional communication control adapter.

Conventional communication control adapters (including communication control devices)
Even in the case of a dedicated adapter with a fixed communication procedure (communication protocol) as shown in (a) of this figure, or a general-purpose adapter with no fixed communication procedure as shown in (b) of the figure, When changing the communication procedure used on a certain line, disconnect and stop the -degree lines ■ and ■, and then reload (IPL) the software for the communication procedure of the [phase] that requires the change. ) was necessary.

Therefore, there was a problem in that communication was disconnected up to line (2), which did not require any change in the communication procedure.

FIG. 7 is a diagram showing an example of the configuration of a conventional communication control adapter.
The communication procedure of the layer 81 control unit, -.-) was configured in series. In other words, the coupling relationship between each communication procedure control section 23 was determined in advance.

In this figure, the connection relationship has been determined such that procedure B1 is below procedure 1, and procedure C1 is below it. Therefore, there is a problem in that it is difficult to change the combination of communication procedures for each layer.

In view of the above-mentioned conventional drawbacks, the present invention provides a communication control adapter that supports multiple communication lines and layered communication procedures;
Or in a communication procedure management method in a communication control device,
The purpose of the present invention is to provide a method of configuring a communication control adapter that makes it possible to dynamically change the combination of communication procedures on a line-by-line basis, and that does not affect communication on other lines at all. It is something to do.

[Means for solving problems]

FIG. 1 is a diagram showing the principle of a communication control procedure management system according to the present invention.

The above problem can be solved by providing a communication control adapter or a communication control device with a communication procedure management system having the following configuration.

A communication control adapter or communication control device 2 that supports a plurality of communication lines and layered communication procedures has a plurality of communication procedure control units 23 that control the communication procedures of each layer, and controls each of those communication procedures. A command means 31 from the main unit 1 that individually creates/deletes or activates/deactivates the units 23 and a command from the main unit 1 that changes the coupling relationship between each communication procedure control unit on a line-by-line basis. A means 32 is provided to determine the combination of communication procedures of each layer in a particular line.
Configure it so that it can be changed without affecting communication on other lines.

[Effect]

That is, according to the present invention, the communication control adapter has a plurality of communication procedure control units for each layer in parallel, and each communication procedure control unit can be created/deleted, activated/
To enable deactivation to be performed individually, and to change the coupling relationship between the communication procedure control units on a line-by-line basis by a command from the main body.

This allows the communication procedure for a certain line to be changed without affecting communication on other lines. For example, (1) First, disconnect only the communication of the line whose communication procedure you want to change. Therefore, communication on other lines continues.

(2) Regarding the tapping line, by command from the main unit,
The connection relationship between the plurality of communication procedure control units to be used is changed, for example, by updating the connection table.

At this time, if the necessary communication procedure control section does not exist, the communication procedure control section is created/activated by a command from the main body.

Furthermore, when the connection relationship is changed, if there is a communication procedure control section that is no longer needed, it is deactivated/deleted to save memory resources within the communication control adapter.

(3) What was changed in (2) is the record of the coupling relationship of the communication procedure control unit for a certain line, and does not affect the operation of the communication procedure control unit itself, so is continued.

(4) After changing the coupling relationship as described above, when communication on that line is restarted, the communication procedure has been dynamically changed.

Therefore, in a communication control adapter (or communication control device) that supports multiple lines, it is possible to dynamically change the communication procedure of a certain line without affecting other lines, and to change the communication procedure of a specific line without affecting other lines. You can perform maintenance work on a specific line without affecting the line. Also, create multiple communication procedure control units.

Since it is only necessary to activate the adapter and define its connection relationship, there is a great effect that each communication procedure control section can be shared between different communication control adapters.

FIG. Join table 210, data transfer unit 22.
Each communication procedure (Al-C2) control unit 23. and control command interface 3 are necessary means for implementing the present invention. Note that the same reference numerals indicate the same objects throughout the figures.

Hereinafter, the communication control procedure management system of the present invention will be explained with reference to FIG. 2 and FIG. 3 while referring to FIG.

First, the configuration of the communication control adapter of the present invention will be explained with reference to FIG.

In the present invention, the management section 21 is provided in the communication control adapter 2.
is provided, and this management section 21 manages a plurality of communication procedure (Al-C2) control sections 23, but these communication procedure (81 to C2) control sections 23 exist in parallel, and There is no associative relationship.

The management section 21 is provided with a connection table 210 that stores the connection relationships of each communication procedure (Al-C2) control section 23.

In this connection table 210, which communication procedure is used for each layer is stored for each line. In other words, the coupling relationship of the communication procedure (Al-C2) control unit 23 is stored for each line.

In the present invention, the communication control adapter 2 is provided with a data transfer section 22, which is a common part for transferring data between the respective communication procedure (Al-C2) control sections 23, and Procedure (Al-C2) Information exchange between the control units 23 is performed via this data transfer unit 22.

That is, the data transfer unit 22 performs each communication procedure (A1-C
2) When data is transferred between the control units 23, an inquiry is made to the management unit 21.

The management section 21 examines the connection table 210, and depending on the contents thereof, instructs the data transfer section 22 from which communication procedure control section 23 to which communication procedure control section 23 the data should be passed.

In order to perform the above operations, the management section 21 issues commands to the main body 1 to create/delete and activate/deactivate each communication procedure (Al-C2) control section 23. An interface 31 is provided. It also provides a command interface 32 for changing the coupling relationship between each communication procedure (Al-C2) control section 23 on the coupling table 210.

The operation when changing the communication procedure of a certain line using the above means will be explained using the example of updating the connection table shown in FIG.

1) First, in the initial state, rAl, B1 . They communicate using a combination of communication procedures called cIJ.

2) The communication procedure for line ■ is as follows.
Due to the change in the communication form of communication partner 1, rA2.
B2. Assume that it becomes necessary to change to cIJ.

3) The main body 1 first disconnects communication on the line (2) using the normal communication command interface 4.

4) Next, if the communication control adapter 2 does not include the communication procedure (A2.B2) control unit 23 necessary for changing the communication procedure, the main unit 1 sends a command interface to the management unit 21. 31, the above communication procedure (A2
, B2) Instruct to create the control unit 23.

When the management unit 21 notifies completion of creation of the communication procedure (A2.B2) control unit 23, the main body 1 activates the communication procedure (A2.B2) control unit 23 using the same command interface 32. Of course, it goes without saying that the creation and activation of the communication procedure control section may be instructed by one command.

5) If there is a communication procedure control unit 23 such as the communication procedure (C2) control unit 23 that is not used on any line, the main body 1 instructs the management unit 21 to deactivate or delete it through the command interface 31. You may give instructions. By doing so, resources such as memory within the communication control adapter 2 can be saved.

6) When the necessary communication procedure control unit 23 is assembled, the main body 1 requests the management unit 21 to change the communication procedure of the line ■ to “A2°B2.CLJ” using the command interface 32. By instructing to update the connection relationship of the line (■) on the table 210, the management unit
1 updates the join table 210.

7) Thereafter, the main body 1 resumes communication on the line 2 using the normal communication command interface 4.

8) The data delivery unit 22 of the communication control adapter 2:
According to the contents of the connection table 210, information is exchanged between the communication procedure control units 23, so communication on the line
2. B2. This is done using a procedure called CIJ.

9) While all of the above is being executed, the main body 1 continues communication on the line (2) using the normal communication command interface 4.

Therefore, the communication procedure (Al, B1.CI) control unit 23 continues to perform communication operations without being affected by the change in the communication procedure for the line (2).

Next, other embodiments of the present invention will be described.

1. In the same way as changing the communication procedure of line ■ as described above, change the communication procedure (A2.82) control unit 23.
Instead, for example, by using a test communication procedure (T1, T2) control unit 23 (not shown), a test can be performed on a certain specific line (2) without stopping communication on other lines. It is possible to improve maintainability.

2. Also, when changing the communication procedure of line ■, the communication procedure (A
2) If you use the communication procedure (0) r NULL j instead of the control unit 23, the above connection table 2
If step 10 has the corresponding step "0", skip that layer and
Information can be passed to the communication procedure control unit 23 in the next layer.

This operation allows the main body 1 to jump over a certain level and directly access the lower level, making it possible to omit communication procedures for a specific level.

As is clear from the above detailed description, in the present invention, since the interface between each communication procedure control section 23 and the data transfer section 22 can be standardized, the design of each communication procedure control section 23 is easy. Moreover, each communication procedure control unit 23 can be used in common between each communication control adapter.

As described above, the present invention provides a communication control adapter that includes a management section, a connection table that the management section can access based on command instructions from the main body, and a plurality of communication procedure (Al-C2) controls that are independent of each other. and the communication procedure (Al-C2
) The above-mentioned command interface that creates/deletes and activates/deactivates the control unit, and the data transfer unit that exchanges information between the control units for each communication procedure (^1 to C2),
By creating/deleting, activating/deactivating the communication procedure (Ai to C2) control unit using commands from the main unit, and changing the coupling relationship of the communication procedure control unit corresponding to the line in the coupling table. The feature is that the communication procedure for each line can be dynamically changed for each line.

〔Effect of the invention〕

As described above in detail, the communication control procedure management method of the present invention is a communication control adapter that supports a plurality of communication lines and hierarchical communication procedures.

Or, in a communication control device that has multiple communication procedure control units that control the communication procedures of each layer, a command from the main unit that individually creates/deletes or activates/deactivates each communication procedure control unit. and a command means from the main unit for changing the coupling relationship between the respective communication procedure control units on a line-by-line basis. is configured to be changed without affecting communication on other lines, so a communication control adapter (or communication control device) that supports multiple lines is required.
In this system, communication procedures for a specific line can be dynamically changed without affecting other lines, and maintenance work on a specific line can be performed without affecting other lines. Also, create and activate multiple communication procedure control units,
