Description

[Detailed Description of the Invention] [Summary] Regarding the function expansion method of protocols using subsets, the purpose is to reduce the amount of software development and prevent the software from becoming complicated. We have set up subsets consisting of special processing programs that group terminal-specific functions as individual processes, and by combining various subsets for various unique functions according to customer conditions with standard protocol processing, it is possible to eliminate the need to change the standard protocol. It is configured to achieve specific functions requested by customers.

[Industrial application field]

The present invention relates to a method for expanding the functionality of a protocol using a subset, and more specifically, the present invention relates to a method for expanding the functionality of a protocol by using a subset, and more specifically, the present invention relates to a method for expanding the functionality of a protocol by using a subset, and more specifically, the present invention relates to a method for expanding the functionality of a protocol using a subset. Regarding a protocol function expansion method using subsets, which adds unique functions to standard protocol processing by creating subsets of unique functions requested by customers that cannot be handled alone, and combining the subsets with standard protocol processing. .

With the diversification of terminal specifications, requests for customer-specific specifications, and the increasing complexity of network configurations, there is an increasing need to quickly provide unique functions that cannot be supported using developed standard protocol specifications alone. ing.

However, if software is developed by incorporating all of the various and unique functions into one standard protocol specification, the number of development steps will be enormous and the software will become complicated.

[Conventional technology]

Conventionally, when there is a request for a unique function from a customer regarding one standard protocol process, the unique function is incorporated into the standard protocol process to provide the customer-specific function. Furthermore, when multiple customers requested various functions, they were all incorporated into standard protocol processing, or the functions were provided as separate, similar protocols.

That is, in the conventional file management method, FIGS. 6 and 7
As shown in the figure, when the standard protocol processing file X incorporates the unique functions A and B, there is only one similar file that incorporates the unique functions A and B.

[Problem to be solved by the invention] When providing protocol processing that incorporates various functions into existing standard protocol (software) processing, as in the conventional method described above, it is always necessary to refile the entire protocol processing. Because of the complexity of the process and the complexity of the protocol processing, the number of man-hours required for testing to confirm the safety of files increases. In addition, when developing a new similar protocol, there is a problem that the overall software development increases and the number of software development steps increases. Furthermore, since many similar protocol processes are derived, there is also the problem that management after development is complicated.

The present invention utilizes the software resources of standard protocol processing, collects unique functions as a subset apart from standard protocol processing, and combines this subset with standard protocol processing to provide unique functions. The purpose is to reduce the amount of development and prevent the complexity of software.

[Means to solve the problem]

FIG. 1 is a diagram explaining the principle of the present invention. As shown in the figure, in the present invention, various and unique functions A and B are subsetted to create separate files α and β from standard protocol processing X.
Manage as. By developing only this subset, it is possible to reduce development man-hours and simplify the software.
By combining subsets and standard protocols, it is possible to quickly provide specific functionality requested by customers.

In this way, data exchangers can provide customer-specific functions,
Alternatively, we provide subsets consisting of programs for specific processing that summarize functions unique to the terminal as individual processing, and create various subsets for various unique functions according to the customer's conditions.
By combining this with standard protocol processing, it is possible to realize specific functions requested by customers without changing the standard protocol.

[Effect]

In the conventional method, specific functions are incorporated into the standard protocol processing file, so there is only one similar file that incorporates the specific functions, but in this method,
As shown in FIG. 1, standard protocol processing files and unique function files are managed as separate files.

The file loading method will be described below, taking as an example the relationship between a packet switching processing device (PTX) that controls a plurality of packet multiplexing devices (AP) in a packet switching device.

In the packet multiplexing device, the programs (files) that control multiple protocol processing are managed by the packet switching processing device.
It shall be loaded into the packet multiplexing device as necessary.

In the conventional method of loading a file from a packet switching processing device to a packet multiplexing device, as shown in FIGS. 6 and 7, it is sufficient to load the entire t1 file in which specific functions are incorporated into existing processing. However, in the method according to the present invention, after loading a file for standard protocol processing, a subset file related to the standard protocol is loaded. When loading this subset file, a function specific to standard protocol processing is incorporated according to the information written in the subset. This means that in the conventional method, the specific functions of the packet multiplexer can be operated at the time the file managed by the packet switching processing device is loaded into the packet multiplexer, whereas in this method, the standard protocol processing file The specific functions become operational after loading the subset file.

In the present invention, in general, the specific functions required by customers for standard protocol processing are diverse, but the specific functions can be provided by making slight changes to the standard protocol processing. Noting that, the first
rI! The file management method shown in J is used, and only unique functions are developed as a subset. In order to incorporate this subset into standard protocol processing, a non-traditional file loading method is used.

First, as shown in FIG. 1, the functions requested by the customer are divided into subsets, and the subsets as shown in FIGS. 2 and 3 are created into files.

The filed subset is loaded into the external storage device (EX) 45 of the packet exchange processing device (PTX), as shown in FIGS. 4 and 5, independently of the standard protocol processing file.

In FIG. 4, an external storage device (EX) 45 contains a file X containing standard protocol processing X (hereinafter referred to as standard X) and a file containing subset A of standard X (hereinafter referred to as A of X). α, a file β which is a file of standard X subcella) B (hereinafter referred to as B of

According to the illustrated example of the line management table, for the packet multiplexer (APO) 42, the standard protocol is only standard X, no subset is loaded, and both the a-power LOO and LOI are standard X.

Regarding the packet multiplexer (API) 43, the standard protocols are standard X and standard Y, the subsets are A of X and B of X, output LIO is a combination of standard X and subsets A and B, and output Lll is standard Y. It is. Regarding the packet multiplexer (AP2) 44, the standard protocols are standard X and standard Y, the subset is B of X, and the output L20

Outputs LOO to L21 of the bus mask multiplexer are connected to telephone terminals, facsimile machines, PBXs, and the like.

FIG. 5 shows a connection with a packet switching processing device focusing only on the packet multiplexing device (API) 43 in FIG. An example of adding the relationship of files loaded to is shown below.

In FIG. 5, the subset files α and β in the external storage device 45 are created by rope ink to the packet multiplexing device (API) 43 (executed when restarting the Z heavy device, etc.). The packet multiplexing device/line management table (
A predetermined standard protocol processing file is loaded into the packet multiplexing device according to the information in the AP/line management table, and then loaded into the same device.

In the packet multiplexing device (API) 43, the subset control unit 51 changes the standard protocol processing file of the subset file α or β loaded from the packet switching processing device 41 according to the format of incorporating the subset in the subset according to the contents of the subset. That is, if the subset is in patch format, change the contents of the segments SEG2 and 5EG3 of standard protocol processing Replace.

At this point, the standard protocol processing modified by the contents of the subset is output with a unique function incorporated therein.

As a result, the output line LIO is controlled by a protocol in which functions A and B specific to standard protocol processing X are added. Further, the line Lll is controlled by the standard protocol processing Y protocol.

〔Effect of the invention〕

In data exchange, etc., various protocols are controlled simultaneously, and these protocols are initially developed as standard protocol processing based on standard specifications.

However, standard protocol processing alone cannot provide the customer-specific functions requested by many customers; however, such unique functions can often be satisfied by making slight modifications to standard protocol processing; In addition, customers require standard protocol processing in addition to specific functions;
and the provision of unique functions as soon as possible.

In such an environment, if all unique functions were built into standard protocol processing files and protocol processing was developed to meet customer needs, the amount of development man-hours would be enormous.
It has become impossible to provide functionality early.

The present invention makes it possible to simplify protocol processing, reduce the amount of development, and provide unique functions early by dividing unique functions into subsets, making the files independent, and combining the subsets with standard protocol processing.
