(1) Distribution Server Information Management System The distribution server information includes (A) where and in which distribution server the divided data is stored (current address of the data), and (B) free space of each distribution server. It is specification information such as capacity. The distribution server information is stored and managed by the distribution server information DB. First, a candidate server to be a distribution server is registered in the distribution server registration DB. Also, registration information such as the line, specifications, and free space between each distribution server and the candidate server is stored in the distribution server information DB. The distribution server information DB receives the divided and transmitted distribution information from the content management server, receives change information such as storage, addition, and deletion, and updates the information each time. In accordance with the request from the content charge management server, the distribution server information, (A) where and in which distribution server the divided data is stored (current address of the data),
(B) Provide specification information such as the free space of each distribution server.

(2) Upload of Content Data to Distribution Server (Server Data Update System = Addition) Upload of content data is performed under the following server data update process. The server data update is performed under two main processes of 1) update of the management server and 2) update of the upload / portal server.

FIG. 5 is a flowchart showing a basic flow of information update processing of the management server when adding a content. First, content data is uploaded from the content provider through the upload portal server through the management server in charge. The responsible management server receives the content. The received content is subjected to processing such as encryption, and the encryption key is transmitted from the responsible management server to the distribution server information DB. next,
The responsible management server divides the content. For dividing the content, the rule of division itself can be encrypted using random numbers of light or chaos theory. The encryption key is also transmitted to the distribution server information DB and stored. The above operation is performed for each divided data obtained by dividing the original content.

In the present invention, data that is uploaded from a content provider and divided and stored in a distribution server and that is re-integrated during or after download includes characters such as text and characters created using a word processor. Information, image information, image data, 3D image data, moving image data, animation, audio data, e-books such as PDF files, presentations, slides and slide shows, real-time images, programs and game software, Web, e-mail and Web mail, Includes news, audio, proposals, or any combination of these, as well as any content. In addition to dividing and storing static data such as still images and re-integrating them later, moving images and animations, slide shows and other dynamic data as described later, or chronological data such as e-books and presentations This includes the case of dividing and reintegrating data including elements. Furthermore, the case where data is temporarily and temporarily divided or re-integrated, such as data that can be browsed by television, voice, radio, live broadcasting, or frame-by-frame transmission, may be included. Furthermore, by dividing and storing calculation software, search software, etc., or storing them in a mirror server, executable software can be distributed and distributed to maintain data security and security.

Alternatively, a split type conference room (chat bulletin board), a conference room using a mobile server, a conference room using a mobile / split type server, a conference room not provided in the server, and the like can be installed and operated.

Next, the management server accesses the distribution server information DB and extracts an optimal distribution server to be installed from the distribution server candidates. The distribution server is automatically extracted from server data such as the total data amount, the specifications of the installation server, and the line. In some cases, manual or semi-manual operation is also possible. Then, the data of the divided content is transmitted to the extracted distribution server and stored. A record of the data arrangement (distribution server information and content parts information) indicating which distribution server the divided content is stored in is transmitted to the distribution server information DB and stored. The above operation is performed for each divided data obtained by dividing the original content, and all the data is stored in a plurality of distribution data.

After the data storage operation is completed, the result is transmitted to the upload portal server. It also takes a record of the uploaded data and sends the log to the log portal server.

As a division method for dividing data of contents, software, and the like stored in the distribution server, the following division method can be used, for example. First,
The length of the data to be divided can be regularly divided according to the amount of data and the like. Next, the length of the data to be divided can be irregularly divided using a random number of light, chaos theory or the like. Further, it is possible to store the individual data after the division in an irregular group. Alternatively, individual data after division can be regularly grouped and stored. Furthermore, the data to be split can be encrypted before or after the split, which is desirable for further preserving the confidentiality of the data. In addition, it is also possible to encrypt each of the divided data. One type of content, software, or the like can be encrypted using a plurality of types of encryption means, and the encryption method used here can be randomly extracted and used.
Encrypted data of one content or software can be managed by a plurality of management servers.

When uploading content or the like, if the data is to be divided first, 1 the content provider divides regularly 2 the content provider terminal divides irregularly 3 the upload / portal command from the portal server Regular division 4 Various methods such as irregular division by the command from the upload / portal server can be adopted. Alternatively, as a method for the user terminal to select a distribution server, for example, the following various methods can be adopted. 1 View the response speed of the distribution server 2 Refer to the route information to the distribution server 3 Download the test file from the distribution server,
Measure speed 4 Automatically receive and cache information about distribution server in advance 5 Use dedicated protocol 6 Use existing Internet protocol 7 Randomly select 8 User configure

All the following processes are performed through the upload portal server. The content provider sends content information (file name, amount of information, etc.)
The portal server receives the content information. The upload / portal server accesses the management server information DB and extracts a new charge management server. The extracted responsible server information is transmitted to the content provider. Next, the upload portal server instructs the responsible management server to receive the content, and the content provider uploads the content through the upload portal server. Upload the content to the responsible management server. Receive the content reception result from the responsible management server. If there is no problem, record the responsible management server information. The responsible management server information and the content information are registered together in the management server information DB.

When adding content to the distribution server,
When the portal server only points to the management server, or when the portal server acts as a gateway, as a process for determining which distribution server stores the divided data, for example, the following method is used. Can be taken. For example, the distribution server can be automatically determined based on the specifications of the distribution server, or can be specified by specifying the distribution server according to the determination of a system administrator or the like. In addition, by using random numbers of light, chaos theory, and the like, a distribution server can be selected irregularly. In addition, it is possible to select distribution servers by combining them with the security and other ranks required for the stored data, for example, by classifying the distribution servers according to their ranks and the like according to their specifications, lines, and security. it can.

FIG. 2 is a flowchart showing an example of a basic processing flow of a client program display application (normal reception) at the time of content distribution. First, the application transmits content information (address information and the like) to the proxy program in the user terminal, and requests the proxy server for the content information. At this time, techniques such as HTTP, streaming, and the like can be used for smooth reception. Next, the proxy server receiving the request responds, receives the data, and analyzes the header of the received data. Next, it receives the management server information, starts the corresponding server reception process, and receives data according to the process of the corresponding server according to the management server information and the content information. The content data is transmitted to the application, and the above operation is sequentially repeated according to the instruction of the parent process of the proxy server, and the content is sequentially displayed.

Through the above processing, a distributed server-based content and software distribution service system that receives data in a divided form at the time of downloading and reintegrates the data after downloading is realized.

As described above, the basic system of the present invention has been described in detail. However, the present invention is not limited to the above-described embodiment, but falls within the scope of the invention described in the appended claims.

Further, in any of the embodiments of the present invention, the movement, addition, and deletion of data include the movement, addition, and deletion of a database. Log portal servers, log DBs, etc. are also subject to movement, addition, and deletion. For example, 1 split the log server 2 do not split the log server 3 move without splitting the log server 4 split and move the log server 5 similar cases are possible in the log DB

According to the number of accesses from the user,
A content and software distribution service system based on a distributed server, characterized in that the number of servers can be automatically increased or decreased, is realized by the following configuration. Original server Multiple mirroring candidate servers Software for mirroring Virtual server for mirroring

According to the present embodiment, the mirroring can be performed automatically, so that the risk of the server going down is reduced. Also, the number of distribution servers can be increased in accordance with the increase in the number of accesses, or even if the number of accesses increases, there is no need to enlarge the management server. There is no need to invest in fixed mirror servers. In addition, the number of servers can be increased according to changes in the number of accesses according to time of day and seasonal changes. Idle servers can be used in units of hours and periods in which idle servers can be used. Since the server can be temporarily rented, there is an advantage that waste of capital investment can be reduced, and a server rental business can increase business income.

The basic processing flow of this embodiment is as follows. First, when a certain number of accesses to the original server are collected, a server to be mirrored is extracted from the registered servers. Next, copying of the original server to the extracted server is started. Assign a virtual domain to the automatically mirrored server and start operation as a mirror server. When the number of accesses drops below a certain number, end the work as a mirror server and delete the information as a mirror server. Stand by as a candidate server for the next automatic mirroring server.

1. The mirror server can be used by renting an idle server or the like in addition to the case where the system administrator of the present invention prepares the mirror server. In this case, the lending relationship of the server does not matter whether it is continuous, limited, temporary, or a fixed period of time. In this case, for example, the following is possible. Pre-register rental servers for automatic mirroring by time of day. For the server that wants mirroring, select the conditions for using the temporary mirroring server and contract in advance. The role of "insurance" for servers that want temporary mirroring when the number of accesses increases. The server that wants to mirror,
Membership fee as "insurance fee" and rental cost will be paid. Depending on the conditions, it will be possible to increase the number of mirroring servers to infinity.
Mirroring usage limit is determined and a deposit is collected accordingly. Records how much the mirroring server has been used, and notifies the system administrator server, the rented server, and the server that provided the rental, respectively, of the market situation and the associated billing information. The rental fee charged to the server to be mirrored is set according to the size of the server and the required line speed, etc., and charged according to the usage time. The rental fee for the server used for the mirroring is set based on the line conditions and computer specifications, and is paid according to the usage time. The system management company collects the rental fee from the server administrator who borrowed the mirror server. The system management company paid the rental fee to the server administrator who lent the mirror server. The system administrator collects a certain amount as a management fee, such as system operation costs.

The mirror for storing the divided data
Content and software distribution service system by distributed server, which can maintain data security etc. by moving the server, can move the server for a certain period of time or constantly, so that the server can be hacked, cracked, etc. It is a security system to protect. Further, by moving the database at regular intervals or constantly, a security system for protecting the database from hacking, cracking, and the like can be provided.

These systems are realized by the following basic configuration. Original server data Multiple destination candidate servers (pre-registered) Virtual domain Determines the destination, applies random numbers of light, chaos theory,
Encrypted software Software that notifies the destination and current address to the portal site Set a proxy server on the user's computer Ensure that multiple mirror servers exist at all times in case of an accident such as the user's data integration software going down

According to these systems, since servers of the same virtual domain move at regular intervals, it is difficult to pursue the current address of the domain, so that illegal intrusion such as hacking and cracking can be prevented. In addition, the wandering and dispersing properties of the server itself serve as an alternative to firealls. Furthermore, security can be improved by dividing and storing each data file.

In the present embodiment, the "automatic mirroring of server" is applied, and copying and deletion are repeated to move the virtual domain. Therefore, both the management server and the distribution server are continuously moved at regular time intervals or constantly. It is possible. Pre-register multiple servers as destination candidates Data files are encrypted with random numbers of light, chaos theory, etc.Data files are divided and stored on multiple servers When dividing data files, random numbers of light, chaos theory, etc. are also used. Use to enhance security As a prerequisite for movement, data holding the same data is always mirrored, and there are multiple copy servers.Encryption of destinations with optical random numbers, chaos logic, etc., and extraction Copy to destination Start While the management server data is copied like an hourglass, the user can use the software that integrates the server data so that the user can use it even while the data is being moved. Move server

Also in the present embodiment, an idle server or the like can be used as a destination server by rental or the like. In this case, the following processing can be performed. Payment of rental fees to the destination server according to the usage status The server administrator who moves the server pays the system management fee, such as the system management fee, commission, and enrollment fee, to the system management company. Set the hourly unit price in consideration of such factors, and pay accordingly Rent payment from the system management company to the destination computer according to the recorded usage status

The flow for moving the distribution server and the management server consists of the following processes. Flow related to addition / migration / deletion of distribution server Management server flow when adding distribution server Management server flow when migrating distribution server Management server flow when deleting distribution server The flow will be described later in order.
