Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to each layer in an information processing system (for example, a communication control system) that has a hierarchical structure and has an interface between adjacent layers (each layer that realizes the processing performed by the information processing system). Regarding a data type data transfer processing method that performs data transfer processing (communication processing) between (processing means) using data types (control of transfer of data to be transferred between each layer is realized by transfer of control data between each layer) .

0002

[Prior Art] Conventionally, in this type of data type data transfer processing method, data to be transferred (user business data, etc.) is directly exchanged between data transfer means in adjacent layers.
An interface between hierarchies has been realized by directly exchanging control data between data transfer control means in adjacent hierarchies.

0003

[Problem to be Solved by the Invention] In the conventional data type data transfer processing method described above, the data transfer means and the data transfer control means each have separate interfaces between adjacent layers, so it is difficult to add new functions to each. When adding data transfer control means within a hierarchy, in addition to adding a new function to the data transfer control means within each hierarchy, it is necessary to add a new interface for the data transfer control means between adjacent hierarchies. The disadvantage is that the amount of additional work becomes enormous.

[0004] Furthermore, when it is desired to pass control (control data) between layers that are not adjacent to each other, data transfer control means in an intermediate layer, the data transfer control means, and data transfer control means in an adjacent layer are used. Since control is passed sequentially using an interface between layers, there is a drawback that independence between layers regarding data transfer control means is reduced.

[0005] In view of the above points, an object of the present invention is to improve the extensibility of each layer (ease of adding functions, that is, even when a new function is added, it is possible to improve the extensibility of each layer). (no need to modify anything) and improved reliability (improved reliability based on the improved extensibility mentioned above; in other words, reliability due to fewer modifications required even when new functions are added) The object of the present invention is to provide a data type data transfer processing method that can improve the independence between layers.

[0006]

[Means for Solving the Problems] The data type data transfer processing method of the present invention is a data type data transfer process that performs data transfer processing between each layer in an information processing system that has a hierarchical structure and has an interface between adjacent layers. In the method, data transfer means in each layer transfers data to be transferred to an adjacent layer, data transfer control means in each layer controls transfer by this data transfer means, and either data to be transferred or control data. and a layer control means within each layer that realizes an interface between adjacent layers by passing layer control data having the following information.

[0007]

[Operation] In the data type data transfer processing method of the present invention, the data transfer means in each layer transfers the data to be transferred to the adjacent layer, and the data transfer control means in each layer controls the transfer by the data transfer means. , the layer control means in each layer delivers layer control data including either data to be transferred or control data, thereby realizing an interface between adjacent layers.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the data type data transfer processing system of the present invention. The data type data transfer processing method of this embodiment includes a first layer 1, a second layer 2, and a third layer 3 (first layer 1, second layer 2, and third layer 3). 3 is 1 as a whole
processing of two information processing systems).

The first layer 1 includes data transfer means 11, data transfer control means 12, and layer control means 13.

The second layer 2 includes data transfer means 21, data transfer control means 22, and layer control means 23 and 24.
It is composed of:

The third layer 3 includes data transfer means 31, data transfer control means 32, and layer control means 33.

FIG. 2 is a diagram showing the format of layer control data 4 transferred between layers. The hierarchy control data 4 includes hierarchy destination information 41 indicating which hierarchy the destination of the hierarchy control data 4 is, and whether the destination of the hierarchy control data 4 is "data transfer means" or "data transfer control means". It consists of means destination information 42 indicating whether there is any data, and data content 43 in which data to be transferred (user business data, etc.) or control data is stored.

FIG. 3 is a flowchart showing the processing of the hierarchy control means 24. This process includes a layer control data existence recognition step 241, a layer destination information determination step 242, a next layer transfer recognition step 243, a means destination information determination step 244, a data transfer control means layer control data transfer step 245, and a data transfer control means layer control data transfer step 245. The transfer means hierarchical control data transfer step 246 is performed.

Next, the operation of the data type data transfer processing system of this embodiment configured as described above will be explained. Note that the operation when the transfer target data and control data are transferred from the third layer 3 to the first layer 1 will be described here.

First, the case where data to be transferred is transferred from the third layer 3 to the first layer 1 will be explained.

In this case, the data transfer means 31 in the third layer 3 sends the layer control data 4 (layer destination information 41) to the layer control means 24 in the second layer via the layer control means 33.
"First layer" is set in "1st layer", "data transfer means" is set in means destination information 42, and layer control data 4) in which data to be transferred is stored in data contents 43 is sent.

The hierarchy control control 24 sends a message to the data transfer means 21 because the sent hierarchy control data 4 is not addressed to "its own hierarchy" (the "second hierarchy" is not set in the hierarchy destination information 41). The hierarchical control data 4 is passed.

The data transfer means 21 is connected to the hierarchical control means 23.
The layer control data 4 is sent to the layer control means 13 in the first layer 1 via.

The hierarchy control means 13 determines that the sent hierarchy control data 4 is addressed to "its own hierarchy" (the hierarchy destination information 4
1 is set to "1st layer"), and is addressed to the "data transfer means"("data transfer means" is set in the means destination information 42).
is set), the hierarchical control data 4 is passed to the data transfer means 11.

[0021] This allows the first layer 1 to receive predetermined data to be transferred.

Next, the case where control data is transferred from the third layer 3 to the first layer 1 will be explained.

In this case, the data transfer control means 32 in the third layer 3 transfers data to the second layer 2 via the layer control means 33.
Hierarchical control data 4 is stored in the hierarchical control means 24 ("first layer" is set in the hierarchical destination information 41, "data transfer control means" is set in the means destination information 42, and control data is stored in the data content 43). The hierarchical control data 4) is sent.

The hierarchy control means 24 passes the hierarchy control data 4 to the data transfer means 21, since the sent hierarchy control data 4 is not addressed to "its own hierarchy". in this way,
Even if the data content 43 is control data, the data transfer control means 22 is not involved in the transfer of the hierarchical control data 4 at all.

[0025] The data transfer means 21 is connected to the hierarchical control means 23.
The layer control data 4 is sent to the layer control means 13 in the first layer 1 via.

The hierarchy control means 13 determines that the sent hierarchy control data 4 is addressed to "its own hierarchy" and is addressed to the "data transfer control means" (the "data transfer control means" is set in the means destination information 42). Therefore, the hierarchical control data 4 is passed to the data transfer control means 12.

[0027] This allows the first layer 1 to receive predetermined control data.

Next, as a representative explanation of the operations of the hierarchy control means 13, 23, 24, and 33, the hierarchy control means 2 when receiving the hierarchy control data 4 from the hierarchy control means 33
The operation No. 4 will be explained. In this case, the hierarchy control means 24 performs the following processing (see FIG. 3).

When the existence of the transferred hierarchical control data 4 is recognized (step 241), the hierarchical control data 4 is
It is determined whether the destination is "my layer"("secondlayer" is set in the layer destination information 41) (step 242).

[0030] If the destination is not addressed to ``my layer'' in this judgment, it is recognized that ``transfer to the next layer (first layer 1)'' is to be performed (step 243), and the data transfer means 21 is instructed to control the layer. Data 4 is passed (step 246). Hierarchical control data 4 from the third layer 3 to the first layer 1 explained earlier
The processing of the layer control means 24 in the transfer of the data corresponds to this case.

[0031] If the destination is determined in step 242 as being addressed to "my layer", the destination of the layer control data 4 is also addressed to the "data transfer means" (means destination information 42
(step 244).

If it is determined that the destination is the "data transfer means", the hierarchical control data 4 is passed to the data transfer means 21 (step 246).

If it is determined in step 244 that the destination is not addressed to the "data transfer means" (if it is addressed to the "data transfer control means"), the hierarchical control data 4 is passed to the data transfer control means 22 (step 245). .

[Effects of the Invention] As explained above, the present invention provides a data transfer means, a data transfer control means, and a layer control means in each layer, thereby making it possible to realize an interface between layers using only the layer control means. , it is possible to improve the scalability and reliability of each layer.

[0035] Furthermore, when control data is transferred between non-adjacent hierarchies, it is possible to transfer the data without going through the data transfer control means in the intermediate hierarchies, which has the effect of increasing the independence between hierarchies. be.
