Description

E-mail Multiprocessing System and Multiprocessing Method

The present invention relates to an apparatus and a sending method for sending an e-mail through a data communication network, and more particularly, to provide an e-mail sending multiprocessing apparatus and a multiprocessing method capable of effectively processing a plurality of e-mail sending.

In recent years, as the number of Internet users has increased, information retrieval through the Internet has become more common, and accordingly, the importance of E-mail as a communication means has been highlighted. Moreover, e-mail is not only used as a means for communicating between the sender and the receiver, but is widely used as the main means for providing various information. In addition, as the technology of this field develops day by day, the format of the data constituting the main body of the e-mail is not only provided with text data but also written in the form of HTML documents, and also a larger still image. It is also evolving to include videos and videos, and the demands of e-mail users are more diverse and higher. Accordingly, the function of the processing means for sending and receiving e-mails should also be improved, but since the fundamental limitations are not overcome, the number of e-mails to be sent and the data size of the e-mails to be sent cannot be handled. For this reason, if the number of mails to be sent exceeds 1 million, there was a problem such that it takes more than half a day to process.

As one of the methods currently proposed and used as a means to solve the conventional problems, as shown in FIG. 4, a plurality of mail servers each having a unique IP address are installed and a plurality of emails are used using the same. For example, a method of performing dispatch processing.

A feature of the conventional method shown in Fig. 4 is that a plurality of e-mail processing apparatuses (mail servers) each having a unique IP address are provided. Thus, each of the e-mail processing apparatuses 100 and 200 retrieves the e-mail data body from each of the E-memory text storage units 103 and 203, and in the subscriber information storage units 104 and 204 assigned to them. After the subscriber information is obtained, the final e-mail can be combined with the e-mail and some contents of the subscriber information (for example, a name), and sent to the subscriber according to the e-mail address recorded in the subscriber information storage. Works.

In this configuration, the plurality of transmission lines 105 and 205 are physically or logically independent of each other, and the electronic mail processing device 101 is composed of an object physically separated from other electronic mail processing devices 200, and each of the storage devices. The recording data of (103, 104) and the recording data of the storage devices 203, 204 are processed independently.

Using this method, it is possible to increase the amount of e-mails processed per unit time in proportion to the number of e-mail processing apparatuses. However, in order to realize such a conventional method, since the number of physical e-mail processing apparatuses allocated to each IP address must be increased, the installation cost increases by the number of increasing processing apparatuses. In addition, since the number of available IP addresses is generally limited, there is a problem that the IP address cannot be infinitely increased in accordance with the increase in the amount of mail transmission. For this reason, it is not possible to solve an exponentially increasing mail transmission processing request by simply increasing the number of processing apparatuses in an arithmetic order.

In addition, since the e-mail address is incorrectly entered in the subscriber information or the subscriber cannot repeatedly receive the e-mail due to a defect in the receiver's communication network, the e-mail address is repeatedly attempted. There is a problem that cannot be overcome.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and provides an e-mail sending multiprocessing apparatus suitable for processing a large amount of e-mail in a short period of time, without increasing equipment or consuming an IP address for a separate e-mail server. It is technical problem to do.

By providing such a configuration, a separate e-mail which removes from the work area regularly and removes bad e-mails remaining in the third storage means repeatedly and unnecessary in the e-mail sending processing means is repeatedly lost. By allocating work to the processing unit, delays in dispatch processing can be eliminated.

Hereinafter, with reference to the accompanying drawings to explain the configuration of the present invention in more detail.

1 is a schematic block diagram showing the configuration of an electronic mail sending multi-processing apparatus according to a first embodiment of the present invention.

The e-mail sending multiprocessing apparatus of FIG. 1 mainly includes a sending mail server 1 connected to a transmission line 8, and a storage device 2 connected to a sending mail server 1 and an internal data bus 7. Consists of components.

The sending mail server 1 is configured to include an email sending processing means 10 and an email writing means 20.

In addition, the e-mail sending processing means 10 includes a plurality of e-mail sending processors 11, 12 and 13, a scheduler managing a work schedule between the plurality of e-mail sending processors, and a plurality of e-mails. And a work area divider 14 for allocating / reassigning the logically divided areas in each of the dispatch handlers and the storage device. In addition, although separately shown in the drawings, it may include a work assignment table 9 for designating a work area allocated / distributed by the work area divider.

In addition, it is preferable that at least one of the plurality of e-mail sending processors 11, 12, 13, ... (for example, 13) is configured as an auxiliary processor. Thus, the subprocessor 13 finds only the mails whose mail processing has failed (email transmission error) due to some cause such as a failure of the receiving mail server, an error in the communication line, a failure of the e-mail address, or a change of the e-mail address. It is desirable to have the treatment regularly.

The number of the plurality of e-mail sending processors 11, 12, 13, ... need not be particularly limited and can be increased to infinity as the capacity of the system allows. If your email dispatcher consists of multiple daemon programs running under the Linux operating system as a kind of RAM resident, for example, you could have 256 main processors and 128 coprocessors running in parallel, It may be configured.

In addition, each of the plurality of subprocessors 13 are paired with a plurality of other main processors divided into a plurality of groups to form a group, and each group sends an e-mail having different e-mail body data. Can be designed to process. However, it is not necessarily limited to the implementation of this form. In addition, preferably, the subprocessor 13 may include one or more separate subprocessors (not shown) for professionally processing the e-mails that have not been sent out.

3 shows an example of a method of organizing such a plurality of e-mail sending handlers in groups.

In FIG. 3, the case where 101 e-mail sending processors are provided is explained. Here, the tenth, twentieth,... The e-mail sending processors of No. 100 and No. 101 were set as subprocessors, and the rest were set as main processors. Thus, each of the tenth to the tenth subprocessors is the first to the ninth, the eleventh to the nineteenth,. The main processor of No.91 to No.99 finds and sends out only the e-mail which has failed in the sending process. In addition, the 101-second subprocessor finds only the e-mail that has failed the sending process in the 10th to 100th sub-processors to send out the mail. This process can be extended, but if the sending process is not performed even after the preset number of times (e.g. 50 times) or the predetermined time period (e.g. 5 days) is attempted, it is determined that the address is incorrect or the address is changed. Delete from sender list.

On the other hand, it is preferable that the re-sending process of the sub-processor is performed after a predetermined time has elapsed after the main processor has processed the shipment. For example, the subprocessor (No. 10 to No. 100) resends the e-mail that the main processor failed to send at 20 minute intervals, and the sub processor (No. 101) for the sub processor is another sub-hour at 1 hour interval. Allow the processor to resend a failed e-mail. And, if another subprocessor is added, the subprocessor will resend the failed e-mail every 5 hours.

The e-mail creating means 20 creates a final e-mail to be sent by combining the recorded contents of the e-mail body data storage device 3 and the subscriber information storage device 4 described later, and this e-mail storage device. Record it in (5).

The mail server 1 for sending in this configuration can be designed specifically for sending an email, but can also be configured using a general-purpose computer.

In the case of configuring the sending mail server 1 using a general-purpose computer, the plurality of email sending processors 11, 12, 13, ..., the scheduler 15 and the work area divider 14 are included. The email sending means and the email writing means 20 are generally provided in the form of a microprocessor and an executable program processed by the microprocessor. The job assignment table 9 can be configured by utilizing a temporary storage device such as RAM. In addition, an operating system for operating a general purpose computer is not particularly limited, and for example, NT, OS2, UNIX, Linux, or the like may be used.

In particular, when each of the e-mail sending means is provided in the form of a resident-type execution program that operates independently of each other, the plurality of e-mail sending processors 11, 12, 13, ... is configured as a daemon program resident in RAM It is preferable. Thus, a plurality of email composing handlers monitor whether the email has been created (or created and stored in the designated storage device), and if the email to be sent from their workspace is monitored, send the email to the subscriber. Process.

The storage device 2 stores an e-mail body data storage device 3 for recording a body of e-mails to be sent to a plurality of subscribers, and information such as name, address, contact information, e-mail address, etc. of the subscribers in the form of a database. The e-mail data created by the e-mail writer 20 is recorded on the basis of the contents of the subscriber information storage device 4 for recording, the e-mail body data storage device 3, and the subscriber information storage device 4; And an e-mail storage device 6 for storing only the e-mail recorded in the e-mail storage device 5 and having failed to be sent out.

The above-described storage devices 3, 4, 5, and 6 constituting the storage device 2 do not necessarily mean that they are physically separated, but the data storage areas of the storage device 2 may be logically divided. Approximately equivalent effect can be obtained. In addition, since it means logical division, there is no need to follow the physical recording order of data in one storage device.

For example, in the case where N e-mails are stored in the storage device 5 in order, and there are 10 main processors and one subprocessor, the first main processor includes the first, the eleventh, Twenty-first To send an e-mail to the second main processor. Send an e-mail from, , The tenth main processor is 10th, 20th, 30th,... You can send an e-mail.

Then, only the e-mail to be processed by the subprocessor 13 can be moved to a separate storage device 6 and recorded. This case is particularly effective when a plurality of main processors 11 and 12 are designed to delete the e-mail after the e-mail is successfully sent. This case will be described in more detail. In Fig. 1, the e-mails AAA, AAB and BAA have been successfully deleted and deleted from the storage device 5, and the e-mails AAC and BAB have been deleted from the storage device 5 due to unsuccessful sending, and the dedicated storage for the subprocessor. Indicates that it has moved to the device (or storage area 6). In this case, it is not necessary to move physically, and instead of deleting from the storage device 5, by giving a notation bit indicating whether or not the message is successfully sent to the data of the corresponding e-mail, and simply performing a notation indicating failure to send to this bit. In addition, the sub-processor 13 may be made to recognize that the object of the dispatch operation by checking only this failure indication. However, in the case of setting another coprocessor to assist the coprocessor 13, another notation bit is added again to distinguish whether the coprocessor is to be processed or to be processed by another coprocessor. This may have the side effect of increasing data size. Therefore, in consideration of this case, it is preferable to move to a separate dedicated storage device 6 at least once.

The work assignment table of FIG. 1 is provided for the purpose of identifying which of the work areas allocated to the plurality of e-mail sending processors 11, 12 ... is assigned to the data area of the storage device 5. This work assignment table may be marked in a portion of temporary storage area, such as RAM, associated with each dispatch processor.

The work area divider 14 is a means for performing the function of allocating the data area of the storage device to the work area of the email sending processor.

This work area distributor 14 divides the data area of the storage device 2 in a given manner and allocates a work area to each of the e-mail sending processors 11, 12,...

As the manner in which the work area divider 14 allocates a work area, various examples can be given. First, a plurality of e-mail sending processors are arranged in order of generating e-mails generated by a plurality of e-mail creation processors. Consider sequentially assigning to. Specifically, for example, the first generated e-mail is composed of 50 e-mail creation handlers and 100 e-mail sending handlers, and is assigned to the first e-mail sending processor 11. The mail is allocated to the second email sending processor 12,... The 100th generated e-mail may be allocated to the 100th e-mail dispatch processor (not shown), and the 101st generated e-mail may be assigned to the first e-mail dispatch processor 11. . The relationship between the number of installations of the e-mail creation processor and the number of installations of the e-mail sending processor is not particularly limited, and may be variously set within the system limits by an administrator or the like regarding the processing speed of a given job. If the number of the e-mail creation processor and the e-mail sending processor is the same, the correspondence between them may be 1: 1.

In addition, when the e-mail creation speed of the e-mail creation destination is faster than the dispatch processing speed of the dispatch processor for any e-mail, the created e-mail is accumulated in the storage device. At this time, a case may be considered in which data areas of the storage device for recording the e-mail are sequentially assigned to the work areas for the plurality of e-mail sending processors 11, 12,... For example, suppose that e-mails created by an e-mail creation processor are recorded and stored in sequence for an arbitrary virtual address. For the 16 e-mail dispatch handlers, the end of this virtual address ends with 1 (eg, 00000001, 00000011, etc.), the e-mail addressed to the first e-mail sending processor 11, the e-mail addressed to an address ending in 2 (eg 00000002, 00000012) to the second e-mail sending processor 12,... An e-mail addressed to an address ending in A (eg 0000000A, 0000001A) may be assigned to work with the A-mail dispatch handler.

As another example, the data area of the storage device is allocated to an arbitrary address. Specifically, for example, an e-mail designated as 00000001 at 10000000 is sent to the first e-mail sending processor 11, and an e-mail indicated at 10000001 at 20000000 is sent to the second e-mail sending processor 12. You can allocate workspaces by,, and so on. In this case, the processing speed of each e-mail dispatch processor 11, 12, ... is different, so if at least one e-mail dispatch handler is finished and rested, check the new e-mail dispatch handler. It is desirable to have a variable setting function so that a work area can be allocated.

Hereinafter, with reference to FIG. 2, 2nd Embodiment which concerns on this invention is described.

The second embodiment of the present invention shown in FIG. 2 differs from the first embodiment in that it does not include separate e-mail creating means (20 in FIG. 1) and e-mail storage devices 5 and 6. . In this case, the case where the e-mail body having the same contents is sent to all the subscribers without adopting a configuration in which the e-mail body is edited in a form suitable for each subscriber to create a separate e-mail is adopted.

Therefore, a plurality of e-mail sending processors 11, 12, 13, 31, 32, 33 create an e-mail preparation based on the information recorded in the e-mail data storage 3 and the subscriber information storage 24. And (in fact, it's just a combination).

The plurality of e-mail sending processors 11, 12, 13, ..., 31, 32, 33 in this second embodiment can also be logically divided into a plurality of groups as in the first embodiment. Thus, each group can be designed to create and send an e-mail for different e-mail data. That is, the first group dispatch processor 11, 12, 13 dispatches the email data A to the subscriber for the email information providing service, and the third group dispatch processor 31, 32, 33 sends the email data. Send B to the subscriber for the e-mail information service.

A plurality of data areas of the subscriber information storage device 24 in the second embodiment shown in FIG. 2 can also be set as a work area for each of the plurality of e-mail sending processors 11, 12, 13. At this time, the setting method of the work area can be made in substantially the same way as the work area setting for the data area of the e-mail storage apparatuses 5 and 6 described in the first embodiment shown in FIG. .

In addition, the electronic mail sending processors 11, 12, 13, ..., 31, 32, 33 of the second embodiment shown in FIG. 2 also have the main processors 11, 12, 31, 32 and the auxiliary processor 13, ..., 33), the subprocessor may be configured to resend the failed e-mail in the main processor. In this case, too, since it is made by the method equivalent to embodiment mentioned above, detailed description is abbreviate | omitted.

The HIT TABLE shown in FIG. 2 is provided so that the coprocessor can easily identify its work target. This heat table is used as a means for indicating whether or not an e-mail transmission has been successfully performed for each subscriber for each e-mail data stored in the e-mail data storage 3. The heat table may be provided with a separate area in the temporary storage device such as the storage device 2 or the RAM not shown in the physical configuration. It may also be done by adding a confirmation bit.

The job divider 14 may also assign work to a plurality of e-mail sending processors 11, 12, 13, ..., 31, 32, 33 using this heat table.

Other configurations are equivalent to those of the first embodiment, and thus detailed descriptions thereof will be omitted.

As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to this embodiment. That is, the features of the configuration of the first embodiment and the second embodiment may be configured in a new embodiment in a form that is combined with each other.

For example, although the heat table is used in the second embodiment and not described in the first embodiment, the heat table is also used in the first embodiment, so that the data area of the electronic mail storage device is used in a plurality of e-mails. It can also be assigned to the dispatch handler's workspace.

In addition, in the above description, the electronic mail body is not particularly limited, but may be applied regardless of the form of text mail or web mail, and may also be applied to the form of attached mail.

In addition, in the above description, a plurality of dispatch processors are described as if each is composed of independent hardware, but need not necessarily consist only of hardware as described above, and may have a form of a plurality of executable programs processed by a microprocessor. have.

By providing a multi-processing apparatus for sending and receiving e-mails as described above, even if the number of subscribers requesting information through e-mails increases, a large amount of e-mails can be quickly generated without adding a special server or consuming additional IP addresses. It is now possible to process shipments without omissions or duplicates.
