Description

[Detailed Description of the Invention] Field of the Invention The present invention relates to a communication address system, and particularly in a computer network where a plurality of processing devices including computers, terminals, etc. communicate through transmission paths. This relates to a method for specifying a message communication address.

Configuration and disadvantages of conventional technology Conventionally, this type of communication address designation method has
There is a method in which a message transmitted through a transmission path has one address for either the sender or the destination (centralized address management method), or a method in which a pair of addresses for the sender and destination are provided in the message ( A distributed address management method is known.

In these systems, a processing device on the originating side and a processing device on the destination side exchange messages with each other, and related processing is performed by both processing devices. For this reason, it has been impossible to sequentially transmit one message to multiple processing devices in a specified order and have each processing device perform unique processing such as processing the data and addresses included in the message. . Furthermore, since the address is fixedly set in the message, there is a drawback that it is not possible to respond flexibly and quickly in the event of a computer network failure or additional processing.

Purpose of the Invention The present invention has been made in order to eliminate the drawbacks of the conventional systems as described above. has a destination address area with addresses of multiple destination processing devices and an origination address area with addresses of multiple origination side processing devices,
The message is transmitted to each processing device in the order of addresses specified in the destination address area, and each processing device performs specific processing such as processing of data and addresses included in the message. It is an object of the present invention to provide a communication address system that allows each processing device on the destination side or the sender side to easily and reliably perform the specific processing, and improves message transfer efficiency. The purpose is

Configuration of the Present Invention Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a format diagram showing a message applied to a communication address system which is an embodiment of the present invention. In FIG. 1, 1 is a message flowing through a transmission path, 2 is a destination address area (DAF), 3 is an originating address area (OAF), and 4 is data. In the destination address area 2, the addresses of the destination processing devices to which the message 1 is sent are written in order, such as a first destination address, a second destination address, a third destination address, and so on. As a specific example, if (first destination address, second destination address, third destination address) are D, F, G, message 1
is sequentially transmitted to the processing device with address D, then to the processing device with address F, and then to the processing device with address G, and each processing device performs the above-mentioned unique processing. The originating address area 3 includes a first originating address, a second originating address, and a third originating address.
The address of the originating processing device through which the message 1 passed is written in order, such as the originating address and so on. As a specific example, (first originating address, second originating address, third originating address) are A, D,
In the case of F, the history indicates that this message 1 was first generated in the processing device at address A, then passed through the processing device at address D, and finally sent from the processing device at address F. It will be done.

Operation of the present invention FIG. 2 is an explanatory diagram showing the operation mode of the communication address system which is an embodiment of the present invention. FIG. 2 shows the destination address area 2 when the processing device at address A sends a message 1a, passes through the processing devices at addresses D and F, and finally reaches the processing device at address G. The transition with originating address area 3 is clearly shown. The first destination address in the destination address area 2 of the message 1a sent from the processing device at address A is D, and the first destination address in the sending address area 3 is
The originating address is A. After this message 1a arrives at the processing device at address D and undergoes the above-described specific processing, the address is changed as shown in message 1b.

That is, message 1b is message 1a
The first destination address D becomes the second originating address, and the second destination address F and third destination address G become the first destination address and the second destination address, respectively. Here, the first originating address A remains unchanged. Next, the same algorithm is used in the processing device at address F to generate message 1c, and in this way, A→
The information is transmitted to the processing devices having respective addresses in the order of D→F→G, and the above-mentioned unique processing is performed at each processing device.

FIG. 3 is a detailed format diagram showing data 4 of message 1 in FIG. FIG. 3 specifically shows what kind of processing is performed in each processing device at addresses D, F, and G. As shown in FIG. 3, data 4a includes a basic job control statement 5 that specifies memory capacity and execution priority, a compile control statement 6 for compiling on the processing device at address D, and a command for compiling on the processing device at address F. , an execution control statement 8 for execution by the processing device at address G, and inter-processing device transfer data 9 for storing data necessary for source programs and compilation. Jobs (units of work from a human perspective)
is input at the processing device at address A, and
is compiled by the processor at address F, linked by the processor at address F, and executed by the processor at address G.

Other Embodiments of the Invention FIGS. 4 and 5 are explanatory diagrams each showing the operation mode of a communication address system which is another embodiment of the present invention. In FIG. 2 mentioned above, when the processing device at address D is requested to perform compiling processing, if it determines that it cannot perform this processing, there is a method for finding another processing device to perform the compiling processing on behalf of the processing device, and how to perform this compiling processing on behalf of the processing device. One possible method is to cancel the process and discard the job. FIG. 4 shows a case where the processing device at address D requests the processing device at address C to perform the compiling process on its behalf. At this time, address D
The processing device inserts the address C into the address of the first destination address D, and sends a message 1e with this first destination address D as the second originating address.
is bypassed to the processing device at address C. After processing this message 1e, the processing device at address C changes the destination address area 2 and originating address area 3, respectively, as shown in message 1f, and then sends it to the processing device at address F to continue processing.

In addition, in FIG. 5, the processing device at address D attempts to transmit the message 1d received from the processing device at address A to the processing device at address F, but as shown by the x in FIG. This shows the case where the message is sent back to the processing device at the original address A because line breaks have occurred at three locations. In this case, the processing device at address D receives the message 1d from the processing device at address A.
In order to return the message to the processing device of the sender's address A, insert the address A into the first destination address D of the destination address field 2, as shown in message 1g, and set this first destination address D as the second originating address. Changes are made to message 1g, which has the following configuration.

As mentioned above, when transferring message 1, the destination address area 2 is stored in the processing device for each address.
By performing dynamic processing such as exchanging, deleting, adding, and inserting the contents of the originating address area 3,
It becomes possible to flexibly and quickly deal with distributed processing, route changes, addition of processing, etc. of the information included in the message 1. Furthermore, in document communication, when a document is circulated among multiple people, it is possible to clearly indicate the person who will circulate the document, and it is also possible to easily keep a history of the document.

Effects of the Invention As described above, according to the communication address system according to the present invention, the destination/originating addresses of a plurality of processing devices are provided in the destination address area and the originating address area in a message, and the destination address area and the originating address are The configuration is designed to perform dynamic processing such as exchanging, deleting, adding, and inserting the contents of the address area.
It has various features such as:

(1) Message transfer efficiency is extremely high because jobs transmitted by messages can be distributed and processed by multiple processing devices, or multiple jobs can be transmitted together in one message.

(2) During the transmission of a message, the message can be bypassed to an unscheduled processing device, making it easier to process additional work.

(3) Since multiple identical addresses can be included in the destination address area, repeated processing is possible.

(4) Since a trace of the address of the processing device through which the message passed is left, it is easy to grasp the status of the processing result.

(5) In the event of a network abnormality such as a transmission line disconnection or computer failure, the route of the message can be changed, and in the worst case, the message can be returned to the starting point, improving reliability and facilitating maintenance. It is.

(6) By allowing only a single address to be held in an address area, it is possible to degenerate to the conventional address management system.

Therefore, it is possible to significantly improve message transfer efficiency and reliability in a computer network that performs communication by transmitting messages processed by a plurality of processing devices through transmission paths. This has an excellent effect of further improving the performance.
