Description

  The present invention relates to a data delivery method in data communication between a server and a client.

  With the rapid spread of the Internet, services such as ticket reservations and banking / securities transactions that were conventionally performed at sales outlets have come to be provided via the Internet. Communication technology has also advanced, and an environment has been established in which services can be enjoyed not only from home but also from mobile phones.

  However, in the conventional method in which service requests are made directly from each client to the server, requests from the client are concentrated on the server. As a result, the communication line capacity and the capacity of the server device to process cannot respond to requests from many users, and depending on the time of day and the access destination, no response will be returned no matter how many requests the user makes. Problems have started to arise.

  As a method for solving these problems, there is a communication method using a proxy. Regarding the data communication method between the server and client using HTTP (Hypertext Transfer Protocol), which is one of the communication protocols, and the data communication method between the server and client via the proxy using a proxy, January 1997 It is described from page 11 to page 13 of the published RFC2068 "Hypertext Transfer Protocol--HTTP / 1.1".

  FIG. 2 shows a data delivery method using a data communication method between a conventional server and client. In the method of Fig. 2, each client (2) individually connects to the server (1) to establish a communication path (3), and uses HTTP, which is one of the communication protocols, to transmit data on the server (1). A service request (100) for (21) is issued, and the server (1) performs data delivery in the form of returning data (21) as a response (110) to each service request (100).

  FIG. 3 shows a data delivery method using the proxy (4) as a relay device. In the method of FIG. 3, the proxy (4) of the relay device includes a relay unit (51) for relaying communication, and a storage area (referred to as a cache area) for storing the relayed data (21) as cache data (40). (53) and a storage unit (referred to as a caching unit) (52) that stores (stores or caches) data (21) in the cache area. When the proxy (4) receives the service request (100) from each client (2), it uses the caching unit (52) to check whether the requested data (21) has already been cached in the cache area (53). .

  For example, a determination is made as to whether or not the cache has been completed by using a table indicating the correspondence between the URL (Uniform Resource Locator) that is the address of the cache data (40) and the address of the cache area (53) in which the corresponding cache data is stored. This can be achieved by searching the table using the URL of the requested data (21) as a key.

  If the corresponding data cache (40) exists, the found data cache (40) is returned to the requesting client (2) as a response (110). If the corresponding cache (40) does not exist, the communication relay unit (51) transfers the service request (100) to the server (1) as a request (200) from the proxy (4), and the server (1) Returns the corresponding data (21) to the proxy (4) as a response (210). The relay unit (51) of the proxy (4) receives the response (210), requests the caching unit (52), and if the cache is possible, the data (21) returned in the response (210) The data is stored in the cache area (53) as a data cache (40). Further, the relay unit (51) relays the response (210), and returns the data (21) returned from the server (1) as the response (110) to the client (2). That is, in the method of FIG. 3, the service request (100) from each client (2) returns a response (110) to the client (2) by the proxy (4) if there is a corresponding data cache (40). By providing a plurality of proxies (4), service requests (100) from clients (2) can be processed in a distributed manner.

  In the data communication method between the server and client shown in Fig. 2, it is possible for the service provider side to respond to a large number of requests by increasing server facilities, but it occurs only infrequently. It is economically difficult to always provide an extra communication line and server device that can handle temporary concentration several times or more than usual.

  In addition, even if the proxy technology of FIG. 3 is used, for example, when a fine response such as changing the service content according to the user attribute is performed on the data provided in the server, in the conventional proxy, Since processing is not possible, the cache cannot be used, and eventually all data communication from each client to the server must be transferred. As in the case of Fig. 2, the server concentrates requests and responds quickly. There was a problem that could not be returned.

  Such a situation may become a serious problem particularly for money-related services such as commercial transactions.

  Therefore, with a limited communication line or server device, it is possible to respond finely according to user attributes, and a technology that can quickly respond to requests from many users, and devices, methods based on that technology, A system is needed.

  The above object can be achieved by the following means.

  First, in data communication between a server and a client, one or more data processing relay apparatuses that perform relay processing while processing data are provided between the server and the client. Thereby, the service request from a plurality of clients is relayed by the data processing relay device, and the server provides the service.

  Specifically, in response to a service request, the server generates and sends extension data in which data processing control information for instructing a processing method of data to be provided is added to the provided data.

  In addition to the communication relay unit and storage unit, the data processing relay device is provided with a data processing unit that performs processing according to data processing control information included in the extended data returned from the server.

  When the data processing relay apparatus receives a service request from the client to the server, the data processing relay apparatus forwards the service request to the server if the data provided for the request is not stored as a cache. Then, after storing the extension data returned as a response to the service request from the server if it can be stored in the storage unit, the provided data included in the extension data is processed according to the data processing control information. The obtained processing result data is returned to the client as a response. In addition, when the provided data has already been stored in the storage unit of the data processing relay device, the data processing relay device does not transfer the service request to the server and processes it using the corresponding stored extension data. I do.

  With such a configuration, the simultaneous service to the scale of 1 million people, which is expected to become important in the future, such as relaying the Olympic results, securities trading, etc., while suppressing the capital investment on the service provider side It becomes possible.

  In addition, requests from important customers can be processed with priority, and the latest information, video data, etc. can be serviced in order to guarantee the service quality.

  In addition, it is possible to deal with differentiated services according to the nature of customers and data, as well as outsourcing and value-added services by data centers and the like.

  The data processing relay apparatus further includes an authentication unit that identifies and authenticates the user of the client by referring to user management information that holds authentication information of each user and user group information that represents a group to which each user belongs. The data processing relay device returns the user management information by the data processing unit by returning the access control instruction information specifying the subscriber information representing the subscriber or the subscriber group of the corresponding data as the data processing control information. It is possible to return data to the client only when the user of the client who is referred to and identified and authenticated by the authentication unit belongs to the subscriber or the subscriber group of the subscriber information indicated in the data processing control information.

  That is, if the requested data is already cached, the data processing relay device can process the service request from the client without transferring the service request from the client to the server. Allocate processing and respond quickly to requests from many clients.

  In addition to access control, various instruction information such as billing is used as data processing control information, so that various processes that have been executed by servers in the past are executed on behalf of each data processing relay device. In response to a request, a response can be quickly returned while performing various processes according to the user and data.

  According to the present invention, it is possible to provide a new communication service solution in which an agent or a communication operator partially performs processing on behalf of a company and performs processing in a distributed manner on the network side.

  Specifically, communication gateway devices that relay and process communication are distributed in the network. The apparatus has a function of caching relayed data, and the content provider can add communication control information to the data to instruct priority delivery of data, user access control, and the like.

  As a result, even for requests from many users, rapid processing using data cached in the nearest device becomes possible. In addition, according to the intention of the content provider, it is possible to provide a service whose quality is changed according to the nature of the user and the data.

  By using the present invention, the server side can provide a large-scale and various services with a simple device.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a logical system configuration diagram showing an outline of the present invention.

  In the present invention, each client (2) and each server (1) are connected via a communication path (3) via a data processing relay device (5) that relays communication between the server (1) and the client (2). Take the configuration. There are one or more data processing relay devices (5) in the system, one or more clients (2) are connected to each data processing relay device (5), and each data processing relay device (5) It is connected to each server (1). In other words, when viewed from one server (1) that provides certain data, the service is hierarchically provided to one or more clients (2) via one or more data processing relay devices (6). ing. Here, the communication path (3) represents a logical connection relationship realized on a physical communication line, and does not limit the physical configuration.

  For example, as shown in the block diagram of the physical system of the present invention shown in FIG. 4, a logical communication path between the client (2) and the data processing relay device (5) shown in FIG. The setting of 3) may be performed dynamically. Specifically, communication lines (17) from multiple clients (2) are bundled by relay devices (routers) (19) and connected to the load balancer (6), and the load is determined based on information such as load information. The distribution device (6) dynamically determines the connection relationship between one or more data processing relay devices (5) connected to the load distribution device (6) and the client (2), and a plurality of clients shown in FIG. A logical communication path (3) with each data processing relay device (5) is dynamically configured. Further, the connection from each data processing relay device (5) to each server (1) may be physically connected via a relay device (router) (19) as shown in FIG.

  In the present invention, as shown in FIG. 1, the server (1) processes and relays the provided data (21) in response to the service request (200) relayed from the data processing relay device (5). The extended data (20) in which the data processing control information (22) instructing this is added to the provided data (21) is returned as a response (210). The extended data (20) may be automatically generated when the server (1) receives the service request (200), or the storage unit (10) of the server (1) is used instead of the original data in advance. It may be held in FIG. 1 shows a state in which the extended data (20) is held in advance in the storage unit (10) of the server (1) instead of the original provided data (21).

  In addition, the data processing relay device (5) of the present invention responds from the server (1) in addition to the communication relay unit (51), caching unit (52), and cache area (53) of the conventional proxy (4). It has a data processing section (54) that interprets the data processing control information (22) of the extended data (20) sent as (210) and performs processing according to the data processing control information (22).

  The data processing relay device (5) may include an authentication unit (55) for performing user authentication of the client (1). Further, a user management server (7) holding user management information (70) such as authentication information of each user may be provided and connected to each data processing relay device (5) via a communication path (3).

  FIG. 5 shows a configuration example of the user management information (70) managed by the user management server (7). User management information (70) of each user includes user name information (71) indicating a user name, user password (72) indicating a password for authentication, and user attribute information (73) indicating user attributes such as gender and age. ), User group information (74) holding the group name to which the user belongs, and the minimum, maximum, default, etc. of service priority allowed for each user, used for controlling the service quality and the like for each user The user priority information (75) indicating

  When user authentication is performed by the data processing relay device (5), the service request (100) also includes user authentication information. FIG. 6 shows a configuration example of the service request (100). As shown in FIG. 6, the service request (100) includes URL (Uniform Resource Locator) information (101) indicating the access target (request destination), and, if authentication is required, client user name information (121 ), Authentication information (102) indicating a password (122) and the like. Further, in the case of charging for each access, charging approval information (103) indicating that charging has been approved is included.

  When user authentication processing is performed by the data processing relay device (5), the authentication unit (55) of the data processing relay device (5) uses the authentication information (102) included in the service request (100) from the client (2). Referring to the corresponding user management information (70) of the user management server (7), the user of the client (2) is authenticated.

  If the data processing relay device (5) is restricted to process data processing control information (22) from a specific server (1), it is included in the data processing control information (22) as will be described later. Using the authentication information of the server (1), the authentication unit (55) also authenticates the server (1). In this case, the server authentication information may be managed as user management information (70) of the user management server (7), for example, in the same manner as general user authentication information. Specifically, as shown in FIG. 5, the server (1) is a pseudo user, and the user type attribute of the user attribute information (73) of the user management information (70) is a pseudo user for server authentication. By distinguishing it from the information for general users.

  In addition, the data processing relay device (5) issues an instruction according to the amount of processing corresponding to the data processing control information (22) when charging the user for access to the paid data (21). When charging the server, a charging management device (8) that performs accounting processing of charging information for each user and server is provided, and the charging management device and each data processing relay device (5) are connected to the communication path (3). You may make it the structure connected by.

  When each data processing relay device (5) provides paid data (21) to the client (2) in response to a service request, the access billing information (300) for each user and data processing control information Processing charge information (310) for each server when processing is executed in accordance with (22) is sent to the charge management device (8), and the charge management device (8) is requested to perform charge totaling processing.

  FIGS. 7 and 8 show a processing flow from when the client (2) issues a service request (100), receiving a response (110) to the service request (100), and displaying it. Hereinafter, the processing flow will be described with reference to FIG. 1, FIG. 7, and FIG.

  First, the client (2) receives a request from the user and issues a service request (100) for the provided data (21) of the server (1) (process 1001).

  The service request (100) is transmitted to a data processing relay device (5) by the setting of the client (2) or the distribution function of the load balancer (7) shown in FIG. 4, and the service request (100) In the data processing relay device (5) that has received the request, the relay unit (51) analyzes the request (processing 1002).

  Furthermore, when performing authentication, the service request (100) is passed to the authentication unit (55), and data processing is performed using the user name information (121) of the authentication information (102) included in the service request (100) as a key. The authentication unit (55) of the relay device (5) refers to the user management information (70) of the user management server (7). Then, the password information (122) of the authentication information (120) included in the service request (100) is compared with the user password information (72) of the user management information (70), and the authentication process is performed. In case of error, the process jumps to the process 1015 in FIG. 8 (process 1003).

  If the authentication is successful, the service request (100) is passed to the caching unit (52), and the caching unit (52) provides data corresponding to the URL information (101) to be accessed specified in the service request (100). (21) or whether the cache (40) of the extended data (20) including the provided data (21) exists in the cache area (53) (process 1004).

  If the corresponding cache (40) exists as a result of the check, the provided data (21) or extended data (20) of the cache (40) is copied from the cache area (53) and taken out, and the process jumps to process 1009 (process 1005).

  If the corresponding provided data (21) or extended data (20) does not exist as a result of the processing 1005 cache check, the service request (100) from the client (2) is sent to the service from the data processing relay device (5). The relay unit (51) transfers the request (200) to the server (1) (process 1006).

  Upon receiving the service request (200) from the data processing relay device (5), the server (1) processes the request, and provides the provided data (21) or the provided data (21) in the requested provided data (21). The extended data (20) to which the processing control information (22) instructing the delivery processing method for 21) is added is returned to the request source (5) as a response (210) (processing 1007).

  Upon receiving the response (210) from the server (1), the relay unit (51) of the data processing relay device (5) sends the provided data (21) or extended data (20) of the response (210) to the caching unit (52). If it can be cached according to the protocol specification, it is stored as the cache (40) in the cache area (53) (process 1008).

  The provided data (21) or the extended data (20) obtained in the process 1005 or the process 1008 is passed to the data processing unit (54), and the data processing unit (54) is provided data (21) or the extended data. (20) A check is made (process 1009). If the obtained data is the requested provision data (21) itself, the process jumps to processing 1015 in FIG.

  As a result of processing 1009, when the obtained data is found to be extended data (20), in the case where the processing instruction by the data processing control information (22) is restricted to some servers (1), further data processing The unit (54) passes the server authentication information (221) included in the data processing control information (22) (details of the data processing control information (22) will be described later) to the authentication unit (55), and sends the user management server ( Have the authentication unit (55) authenticate the server (1) using the user management information (70) of 7). If authentication fails, the process jumps to process 1015 as an error (process 1010).

  The data processing unit (54) refers to the data processing control information (22) of the extension data (20), and sequentially extracts the data processing instructions (222) described in the data processing control information (22) one by one. If there is a data processing instruction (222), the process proceeds to the next process 1012. If not, the process jumps to the process 1014 (process 1011).

  The data processing unit (54) executes processing according to the extracted data processing instruction (222), and obtains provided data (21) to be returned as a response (110) to the client (2) (processing 1012).

  If an error is detected as a result of the process 1012, or if the obtained result requires an immediate response, the process proceeds to a process 1014. Otherwise, the process returns to the process 1011 (process 1013).

  When charging the server (1) according to the data processing, the data processing unit (54) generates processing charging information (310) indicating the charging information for the server (1), and the charging management device Send to (8) (process 1014).

  The relay unit (51) uses the obtained provision data (21) or error information (23) as a response (110), and returns it to the client (2) in a state where unnecessary data processing instructions are deleted (processing 1015). .

  Finally, the client (2) receives the response (110), and displays the response (110) or stores it in the device (process 1016).

  In the case of a configuration in which a plurality of data processing relay devices (5) are arranged between the server device (1) and the client device (2), the above processing procedure is changed as follows, and the provided data (21 ) May be shared.

  First, in the process 1012, when the requester to the data processing relay device (5) is another data processing relay device (5), the processing according to the instruction is performed in advance for each data processing instruction (222). Decide whether to execute each data processing relay device or not, and execute the instructed processing if the fetched data processing instruction (222) is an instruction to be executed by each data processing relay device . Specifically, for example, an instruction regarding a process that should be executed only once in all data processing relay devices, such as a process for a replacement / insertion instruction for updating provided data (21) and a charging process based on a charging instruction, is executed. Without other instructions, the instructed process is executed. In processing 1015, when the obtained provision data (21) is returned as a response (110), if the requester is another data processing relay device (5), not only the provision data (21) but also data processing The extended data (20) including the control information (22) is returned as a response (110). For example, each data processing relay device (5) holds a list of IP addresses of other data processing relay devices that can be a requester for the device, and determines whether the requester is another data processing device, This can be done by comparing with the IP address of the requester.

  In the embodiment of FIGS. 7 and 8, an example is shown in which processing billing information (310) is sent to the billing management device (8) every time billing for data processing is performed in processing 1014. However, the data processing relay device ( The processing billing information (310) may be temporarily stored in 5) and collected to some extent, and then sent to the billing management device (8) or the collected information may be sent.

  FIG. 9 shows data processing relay device (5), server (1), client (2), user management server (7), billing management device (8), replacement / insertion data information server (9) described later, etc. An example of a physical configuration of the apparatus is shown. These devices can be realized on a general information processing device as shown in FIG. Specifically, a processor (11) that executes an information processing program (18), and a memory that holds various types of data that are directly referenced from the information processing program (18) being executed by the processor (11) and the processor (11) ( 12), an external storage device (13) that stores and holds a large amount of information processing programs (18) and various data in a nonvolatile form, and other information processing devices and communication devices connected to the communication line (17) The communication device (14) that transmits / receives data and the input / output device (15) that controls input / output with the operator are connected by a bus (16) for exchanging data, instructions, data arrival notifications, and the like. The information processing program (18) executed by the processor (11) holds procedure information for realizing each of the above-described devices, and the user or the operator is provided via the input / output device (15) as necessary. In response to the instructions from the user or operator, the external storage device (13) is instructed to transfer data between the external storage device (13) and the memory (12), or the communication device (14 ) To read the data arrival notification from the memory (12), or instruct the communication device (14) to send the data on the memory (12) to another information processing device .

  In the embodiment of FIG. 9, the storage unit (10) of the server (1) shown in FIG. 1 and the cache area (53) of the data processing relay device (5) are the external storage device (13) or the memory (12). Realized as part of

  The user management information (70) of the user management server (7) and the replacement / insertion data (900) of the replacement / insertion data information server (9) described later are stored on the external storage device (13) or the memory (12). Managed.

  In addition, the relay unit (51), caching unit (52), data processing unit (54), authentication unit (55), etc. of the data processing relay device (5) shown in FIG. 1 are realized as special hardware. However, the embodiment using the general information processing apparatus of FIG. 9 is realized by the processing procedure described in the information processing program (18). Other functions of the server (1), client (2), user management server (7), billing management device (8), replacement / insert data information server (9) are also described in the information processing program (18). Realized by the procedure.

  Each of the information processing programs (18) described above is stored in advance in the memory (12) or the external storage device (13), or is stored from another device via a portable storage medium or a communication medium.

  Next, embodiments of the data processing control information (22) used in the data delivery method of the present invention and the data processing unit (54) according to the data processing control information (22) will be described.

  FIG. 10 shows a configuration example of the extension data (20). In this embodiment, XML (eXtensible Markup Language), which is a data description language, is used. For example, data processing control information (22) is a tag <data processing control information> </ data processing control information>. The provided data (21) can be distinguished by enclosing the tags <original data> </ original data>. The data processing control information (22) includes authentication information (221) for authenticating the server, access control instruction information (61), billing instruction information (62), etc. Take a configuration with one or more instructions (222) specified. Each data processing instruction (222) is a control instruction tag (60) so that the data processing instruction (222) can be distinguished from each other, such as <access control instruction> </ access control instruction> and <billing instruction> </ charging instruction>. Give instructions in a lump.

  FIG. 11 shows a configuration example of access control instruction information (61) for restricting users who can access data (21), which is an embodiment of the data processing instruction (222). The access control instruction information (61) uses, for example, <access control instruction> as the control instruction tag (60) in FIG. In <Access control instruction> and </ Access control instruction>, <subscriber> tag or <subscriber group> tag is used to add the subscriber name information (611) or subscription of the data (21). Non-subscriber name information (613) or non-subscriber group name information (614) for instructing a list of subscriber group name information (612) and refusing to subscribe with <non-subscriber> tag or <non-subscriber group> tag The default access permission / inhibition information (615) for access from a user who does not belong to either of them is specified by a character string “subscription allowed” or “subscription not allowed”. The subscriber name information (611), the subscriber group name information (612), the non-subscriber name information (613), and the non-subscriber group name information (614) may be specified in any order. . If more than one are specified, they are interpreted and access control is performed in the specified order. However, default access permission information (615) is specified last.

  FIG. 12 shows a detailed processing flow for the access control instruction information (61) of FIG. 11 as a specific example of the processing according to the data processing instruction (222) by the data processing unit (54) in the processing 1012 of FIG. Show.

  First, the data processing unit (54) sequentially takes out the instructions specified in the access control instruction information (61), and executes the corresponding processes according to the instruction contents (process 1101).

  If the retrieved instruction content is the subscriber name information (611), it is compared with the authenticated user name information (121) of the authentication information (102) of the service request (100) (processing 1102). If they match, the process jumps to process 1108 as accessible, and if they do not match, the process returns to process 1101.

  If the retrieved instruction content is subscriber group name information (612), the user management information (70) corresponding to the authenticated user name information (121) of the service request (100) is read from the user management server (7). The user who made the service request by checking whether the user group information (74) of the user management information (70) includes the group indicated by the subscriber group name information (612) It is determined whether the user is a member of the group indicated by the name information (612) (process 1103). If it is a member of the group, it jumps to the process 1108 as accessible, and returns to the process 1101 if they do not match.

  If the extracted instruction content is non-subscriber name information (613), it is compared with the authenticated user name information (121) of the authentication information (102) of the service request (100) (processing 1104). If they match, the process jumps to the process 1109 as an access error.

  If the retrieved instruction content is non-subscriber group name information (614), user management information (70) corresponding to the authenticated user name information (121) of the service request (100) is obtained from the user management server (7). The user who made the service request is checked by checking whether the user group information (74) of the user management information (70) includes the group indicated by the non-subscriber group name information (614). It is determined whether the user is a member of the group indicated by the subscriber group name information (614) (process 1105). If it is a member of the group, the process jumps to the process 1107 as an access error, and if they do not match, the process returns to the process 1101.

  When the fetched instruction content is default access permission information (615), according to the information (615), if “subscription allowed”, access is permitted and the process jumps to processing 1108, and if “subscription not permitted”, access is made. If it is impossible, the process jumps to process 1107 (process 1106).

  If processing 1101 has completed extracting the access control instruction information (61), or if an access error has been detected in processing 1104, 1105, 1106, error information (23) is used as a response (110) and processing 1012 End processing (processing 1107) If processing 1102, 1103, and 1106 indicate that access is possible, the provided data (21) in the extended data (20) is returned as a response (110) and processing 1012 ends.

However, as shown in FIG. 621) may be specified together with subscriber name information (611), subscriber group name information (612), and default access permission / inhibition information (615).

  The processing 1012 of the data processing relay device (5) corresponding to the embodiment of FIG. 17 further includes the subscriber name information (611) in the processing 1108 when it is determined that access is possible according to the processing of FIG. Using the respective billing amount information (621) specified together with the subscriber group name information (612) and the default access permission / inhibition information (615), the process corresponding to FIG. 14 is executed.

  According to the embodiment of the billing instruction shown in FIG. 13 to FIG. 17, the provider of the data (21) can easily set the access billing amount, as well as the minimum amount information (622) and the maximum information (623) of the billing amount. By using it, the administrator of the data processing relay device can be given the right to determine the actual charge amount. In addition, charging can be performed with the consent of the user. Further, in the embodiment of FIG. 17, it is possible to charge with different charging amounts for each subscriber or subscriber group.

  As another embodiment of the data processing instruction (222), an example of instructing partial conversion for the provided data (21) is shown below. As a specific processing example of the conversion, rewriting or insertion is given, but it is not limited to this.

  FIG. 18 shows an example of the instructed replacement or insertion instruction information (63). For the replacement or insertion instruction information (63), for example, <replacement insertion instruction> is used as the control instruction tag (60) in FIG. In <Replacement Insertion Instruction> and </ Replacement Insertion Instruction>, the replacement / insertion position information (631) indicating the replacement or insertion location of the data (21), the replacement size information (632) indicating the replacement size, Replacement / insertion data type information (633) for specifying data to be replaced or inserted, and necessary replacement / insertion parameter information (634) are specified according to the data type to be replaced or inserted.

  Examples of the replacement / insertion data type information (633) include the following.

  "Access time replacement / insertion" indicating replacement or insertion to access time, "User name replacement / insertion" indicating replacement or insertion to user name information for which a service request has been made, data processing relay device (5) side performing relay “Relay address replacement / insertion” indicating replacement / insertion to a certain address determined in step (1), data information server (9) which stores data for replacement or insertion with data classification information (641) as a replacement / insertion parameter (634) ) For the provided data (21) as “replacement / insertion by classification” and “replacement / insertion parameter (634)” indicating replacement / insertion into the data for replacement / insertion of the specified data classification registered in The replacement / insertion parameter is accompanied by calculation target position information (642), calculation target size information (643) indicating a place where the calculation is performed, and calculation type information (644) specifying the calculation type. The calculation result data of the result of performing the specified operation on the operation target specified by the data (634) is specified as replacement / insertion data, specified by the replacement / insertion position information (631) and replacement size information (632). For example, “arithmetic replacement / insertion” indicating that replacement or insertion is to be performed.

  FIG. 19 shows a replacement / insertion process for the replacement / insertion instruction information (63) of FIG. 18 as a specific example of the process according to the data processing instruction (222) by the data processing unit (54) in the process 1012 of FIG. The flow of processing is shown.

  The data processing unit (54) obtains replacement / insertion data according to the replacement / insertion data type information (633) specified in the replacement / insertion instruction information (63) (processing 1131).

  For example, when the replacement / insertion data type information (633) is “access time replacement / insertion”, time information obtained by processing the current service request is obtained and used as replacement / insertion data (processing 1141).

  When the replacement / insertion data type information (633) is “user name replacement / insertion”, the authenticated user name information (121) included in the authentication information (102) of the service request (100) is replaced / inserted data. (Process 1142).

  When the replacement / insertion data type information (633) is “relay address replacement / insertion”, the data processing relay device (5) selects one address from a predetermined (prepared) address group and replaces / It is set as insertion data (processing 1143).

  When the replacement / insertion data type information (633) is “classified data replacement / insertion”, refer to the data information server (9) that stores the data for replacement / insertion and specify it with the replacement / insertion parameter (634). According to the data classification information (641), one piece of data of the designated data classification is taken out and used as replacement / insertion data (process 1144).

  When the replacement / insertion data type information (633) is “calculation replacement / insertion”, the calculation target position information (642) and the calculation target size information (643) specified as the replacement / insertion parameter (634) are indicated. The operation specified by the operation type information (644) is performed on the location of the data (21), and the operation result data is used as replacement / insertion data (processing 1145).

  After obtaining replacement / insertion data by the above processing, the target data (21) for response (110) is targeted, and the part specified by replacement / insertion position information (631) and replacement size information (632) Then, the replacement / insertion is performed using the replacement / insertion data obtained in the process 1131, the result is used as the new response (110) data (21), and the process 1012 is terminated (process 1132).

  When the replacement size information (632) is smaller than the data size of the replacement / insertion data obtained in process 1131 in the replacement / insertion process of the process 1132, the replacement / insertion part and the subsequent parts are shifted backward, and the replacement / insertion data Secure / replace with data size. Conversely, if the replacement size (632) is larger than the data size of the replacement / insertion data, the replacement / insertion data is replaced by the data size of the replacement / insertion data from the position specified by the replacement / insertion position information (631). Therefore, when the replacement size information (632) is 0, the insertion process is performed.

  If the data replacement / insertion instruction methods shown in FIGS. 18 and 19 are used, individual data can be generated on the data processing relay device side using the same data provided from the server 1.

  Application examples are shown below. Each application example is not an option, and one or more can be freely combined.

  FIG. 20 shows an application example of access time replacement / insertion. For example, the trial period start time information (801) described in the data (21) containing trial programs for various software is replaced / replaced / replaced with the replacement / insertion position information (631) and the replacement size information (632). By specifying the insertion target, access time replacement / insertion can be set in the trial period start information (801). In the example of FIG. 20, as a result of the replacement / insertion, time information “2000/01/01 01:23:45” for which access processing has been performed is set in the trial period start information (801).

  FIG. 21 shows another application example of access time replacement / insertion. The access time replacement / insertion is performed by replacing the delivery history information (802) portion of when the data (21) is delivered by the replacement / insertion position information (631) and the replacement size information (632). By specifying the insertion target, access time replacement / insertion can be set in the delivery history information (802). In the example of FIG. 21, as a result of the replacement / insertion, time information “2000/01/01 01:23:45” subjected to the access processing is inserted into the delivery history information (802).

  FIG. 22 shows an application example of user name substitution / insertion. In the link data for referring to other data such as menus, the individual URL link information by specifying the individual URL link information (803) part for referring to the individual data for each user as the replacement / insertion target. A part of (803) can be rewritten with the user name information (121) included in the access request (100), and link data can be generated for each user. In the example of FIG. 22, as a result of the replacement / insertion, the name “user A”, who is the user who made the service request, is inserted into the individual URL link information (803).

  FIG. 23 shows another application example of user name substitution / insertion. Since the license destination information (804) portion indicating the delivery destination of the data (21) is to be replaced / inserted by the user name information (121), the license destination user name information (121) is embedded in the data (21). Can be used to check for unauthorized copying. In the example of FIG. 22, the name “user A”, who is the user who made the service request as a result of replacement / insertion, is set in the license destination information (804).

  FIG. 24 shows an example of dynamically generating local URL link information (805) in a relay network for referring to data in a server as an application example of relay address replacement / insertion. In this application example, one or more local servers (31) in the relay network have a copy (41) of data of the server (1) in advance, and the data processing relay device (5) Depending on the load of (31) and the like, one of the local servers (31) is selected and the replacement / insertion target part is replaced / inserted with the address of the local server (31).

  In the example of FIG. 24, “2.ccc.ddd” is selected from the addresses “1.ccc.ddd”, “2.ccc.ddd”, and “n.ccc.ddd” of the local server (31), “2.ccc.ddd” is inserted in the local URL link information (805). According to this application example, dynamic load distribution processing can be performed on the data processing relay device (5) side.

  According to this application example, load distribution in the data center becomes possible. In other words, the content provider places frequently accessed data in a data center or the like, and the data center distributes the load by distributing the replicated data to a plurality of internal servers as many as required according to the contract amount. It becomes possible to do. Load distribution that is difficult to achieve with a simple load distribution device, such as changing the number of load distributions flexibly or distributed in different regions, can be flexibly realized with authority on the data center side.

  FIG. 25 shows an application example of data replacement / insertion by classification. A data information server (9) storing and managing replacement / insertion data (900) is provided, and connected to each data processing relay device (5) through a communication path (3). In the data information server (9), replacement / insertion data (900) includes classification information (901) indicating the type of data, area information (902) indicating the target area of the information, gender and age of the target Are stored and managed together with target user attribute information (903) indicating the above.

  Each data processing relay device (5) is associated with a client (2) for each region in advance, and holds responsible region information (806). When the data processing relay device (5) retrieves one replacement / insertion data (900) from the data information server (9) in processing 1144, the replacement / insertion parameter ( 634) as well as the data classification information (641) specified in (634), the service area information (806) possessed by each data processing relay device (5), and the service request (100) obtained by referring to the user management server (7) The user attribute information (73) of the user management information (70) corresponding to the user name information (121) of () is also used as a key to search the replacement / insert data (900), and for the obtained replacement / insert data (900 ) Is data for replacement / insertion. In FIG. 25, “A” is specified as the data classification information (641), and data 2 is replaced / inserted in the replacement / insertion area (807) as an example of a service request from a woman over 20 years old in the Osaka area. Has been inserted.

  In the embodiment shown in FIG. 25, the data processing relay server (5) holds the assigned area information (806) in advance. However, the data processing relay server (5) is sent as a part of the service request (100) according to an instruction from the user or the like. The replacement / insertion data information server (9) may be searched using the regional information.

  According to the embodiment of FIG. 25, the creator of the provision data (21) of the server (1) registers the necessary replacement / insertion data in the data information server (9) in advance, so that the region and sex -Data suitable for age can be replaced or inserted into data (21). In addition, the creator of the data (21) does not register the replacement / insertion data in the data information server (9) in advance, but the data processing relay device (5) (or its administrator) side performs various replacement / insertion. Data for insertion is collected and registered separately, and each data (21) creator selects an appropriate classification and inserts / replaces with the authority of the data processing relay device (5) (or its administrator) A service of selecting data is also possible.

  FIG. 26 shows an application example of operation replacement / insertion. For example, in combination with user name replacement / insertion or access time replacement / insertion, license destination information (804) containing the replaced / inserted user name and delivery history information (802) containing access time information are used as the operation type. Licensed information (804): The specified encryption process is replaced or inserted so that the contents cannot be understood by a third party, or the encryption process result is replaced / inserted with falsification detection information (808) at another location. If the delivery history information (802) is later tampered with, the tampering can be detected.

  In the example of FIG. 26, as a result of replacement / insertion, the license destination information (804) is set with the information “User A” who issued the service request, and the delivery history information (802) is the time when the service request was processed. “2000/01/01 01:23:45” is set, and the falsification detection information (808) is the result of encrypting “User A” and “2000/01/01 01:23:45”. A certain “XXXXYYYYZZZZ” is set.

  FIG. 27 shows a detailed example of distribution destination instruction information (65) for distributing service requests for the same data as another example of the data processing instruction (222). In the distribution destination instruction information (65), for example, <distribution destination instruction> is used as the control instruction tag (60) in FIG. In <distribution destination instruction> and </ distribution destination instruction>, there are transfer address information (651) indicating where the data (21) is transferred and subsequent transfer address information (651). Specifies a list of distribution information (650) that is a set of transfer condition information (652) indicating the conditions for transfer to the address. As the transfer condition information (652), the attributes of the service requester, such as region, sex, age, etc. are designated.

  FIG. 28 shows a service request transfer distribution process for the distribution destination instruction information (65) of FIG. 27 as a specific example of the process according to the data processing instruction (222) by the data processing unit (54) in the process 1012 of FIG. Details are shown.

  First, it is determined whether the obtained extended data (20) is data obtained from the cache (40) or data obtained from the response (210) returned from the server (1) (process 1151).

  If the obtained extension data (20) is data obtained from the response (210) returned from the server (1), the data (21) included in the extension data (20) is processed as the response (110). 1012 is ended (process 1152).

  If the obtained extended data (20) is data obtained from the cache (40), the list of distribution information (650) specified in the data processing control information (22) is searched, and the above-mentioned classification-specific data replacement / insertion In the same manner as in, the user attribute information (73) of the service requester included in the user management information (70), the responsible area information (806) held by each data processing relay server (5), or the service request (100 ), Refer to the area information included, and select one distribution information (650) that satisfies the conditions specified in the transfer condition information (652). The transfer address (651) of the selected distribution information (65) Is sent to the processing 1006 as a request destination server (1) address, and the server (1) is requested (processing 1153).

  According to the embodiment of FIGS. 27 and 28, when a service request for a certain data (21) corresponds to transaction processing, or when data (21) must be dynamically generated for each service request, etc. A plurality of servers (1) for processing the service request are prepared, and a distribution destination designation among the plurality of servers (1) is specified from the server side according to conditions such as the gender and age of the region, the user, etc. It becomes possible to specify (5) and have the data processing relay device (5) distribute.

  FIG. 29 shows an example of delivery quality instruction information (66) that specifies the delivery priority, delivery bandwidth, etc. when delivering the data (21) by extending the access control instruction of FIG.

  FIG. 30 shows a detailed processing flow for the delivery quality instruction information (66) of FIG. 29 as a specific example of the process according to the data processing instruction (222) by the data processing unit (54) in the process 1012 of FIG. Show.

  This processing is the same from processing 1101 to processing 1107 in FIG. In the processing 1108 when it is determined that access is possible, each delivery specified together with subscriber name information (611), subscriber group name information (612), default access permission information (615), etc. According to the instruction of the quality instruction information (66), a delivery quality instruction corresponding to the user is obtained, the obtained delivery quality instruction is transmitted to the relay unit (51), the provided data (21) is set as a response (110), and processing 1012 is performed. Terminate the process.

  As a method for obtaining a delivery quality instruction corresponding to the user from the delivery quality instruction information (66), a method of simply using the delivery quality instruction information (66) as it is may be used. Further, a method of checking an instruction from the server and performing necessary correction may be used. For example, the service priority value is used as the delivery quality instruction information (66), and the user priority information (75) as shown in FIG. 5 is added to the user management information (70) held in the user management server (7). Is included, the user priority information (75) of the user is referred to. If the service priority value specified in the delivery quality instruction information (66) falls within the minimum and maximum range of priority values allowed for the user, the service priority specified in the delivery quality instruction information (66) The degree value is used as it is, and when it is out of the range, a method of correcting the priority value within the permitted range closest to the specified service priority value is used.

  According to the delivery quality instruction to the relay unit (51), when the relay unit (51) returns a response (110) to the client (2) in processing 1015, the IP header priority information indicating the delivery priority of the IP packet is displayed. The response (110) with the instructed quality is returned by an operation such as setting to a designated value.

  For example, if the relay device (router) (19) that relays data communication in the system configuration shown in FIG. 4 supports Diffserv, which is a technology that can assign priority to IP packets and control the order of relay processing, The unit (51) obtains the delivery priority according to the delivery quality instruction information, and sets the value in the ToS field (field for designating delivery priority information) of the header of each IP packet that is a data delivery unit. The Diffserv-compatible router can perform delivery using the delivery priority by relaying each IP packet with a priority according to the delivery priority information set in the ToS field.

  For the method of obtaining the Diffserv delivery priority value etc. from the delivery quality instruction information (66), a conversion table describing the conversion method from the delivery quality instruction information (66) to the Diffserv delivery priority value etc. is prepared. Alternatively, a method of obtaining using the same conversion table may be used. Alternatively, the traffic information obtained from a monitoring device or the like for monitoring the traffic on the communication path is used, and the dynamic information is converted in consideration of the traffic information. It may be a method of adjusting.

  According to the embodiments of FIGS. 29 and 30, the delivery quality can be changed according to the user and data. For example, services that are concentrated in access such as securities trading and stream distribution services such as video / audio can be handled by giving priority to important users or giving priority to stream data.

  FIG. 31 shows a configuration example of the processing billing information (310) sent to the billing management apparatus (8) as billing information corresponding to the data processing instruction of the server (1). In this embodiment, the processing billing information (310) includes target URL information (311) indicating the URL of the requested data (21), server authentication information (312) for authenticating the server, and details of the executed processing. Processing content information (313) shown.

  The access billing information (300) and the processing billing information (310) sent to the billing management device (8) are temporarily stored in the billing management device (8), and are aggregated periodically or irregularly. . FIG. 32 shows a flow of periodic counting processing for the access billing information (300) and the processing billing information (310) in the billing management apparatus (8).

  First, referring to the stored access billing information (300), the billing user authentication information (302) is used as a key, and the billing information indicated by the billing billing information (303) is added for each user, and the access bill for each user is added. (Processing 2001).

  Next, referring to the stored access billing information (300), using the billing URL information (301) as a key, add the billing information indicated by the billing billing information (303) for each URL, and add the access fee for each URL. (Processing 2002).

  Finally, referring to the stored processing billing information (310), the server authentication information (312) is used as a key, and the price corresponding to the processing indicated in the processing content information (313) is added for each server. The processing fee is obtained and the counting process is terminated (processing 2003).

  By using the accounting total result of FIG. 32, the operation manager on the data processing relay device side collects the access fee from each user on behalf of the server side, and the collected fee has the corresponding URL data. It is possible to provide a proxy service in which payment is made to the server operation manager and payment is obtained from the server side operation manager in accordance with the contents processed according to the data processing instruction.

  In the above embodiment, each tag can be realized by using, for example, XML (eXtensible Markup Language) which is a data description language.

  It is possible to provide differentiated services by performing detailed control that cannot be realized with conventional routers alone, such as users whose addresses change on mobile devices, and priority delivery according to the nature of data.

  In the present invention, since the processing instruction can be performed with the additional information of the data called the tag, and the data from which the tag is removed after the processing is performed is delivered to the client device (2), the client device (2) and the server (1) New services can be provided without affecting the program.

  Further, the data processing relay device of the present invention includes means for holding the provided data as a cache, and enables distributed service processing using the cache by the control instruction tag for instructing access control as described above. The service request from the client is handled by the nearest data processing relay device, and the data processing relay device directly returns the cached provided data to the client while checking the access. This makes it possible to respond quickly to requests from a large number of users (client devices).

  It is also possible to instruct priority cache for specific provided data (21) by applying the data processing instruction (222). In response to the priority cache instruction, the data processing unit (54) instructs the caching unit (52) to preferentially cache the provided data (21) compared to other data. As a method of preferentially caching by the caching unit (52), for example, there are the following methods.

  First, the cache area (53) is divided into a plurality of areas in advance, and in addition to the cache area for general data, data (instructed in advance by a priority cache instruction from a specific server (1) by a contract or the like) 21) Decide a priority cache area to store only. When the caching unit (52) receives the priority cache instruction, the server is specified by the server authentication information (221) of the data control processing information (22), and the specified cache area for the specified server is instructed. Store data (21) and implement priority caching.

  This method enables effective data to be preferentially cached at an effective location.

  Further, as shown in FIG. 33, by linking the processing relay device (5) of the present invention with a user management server (7) that manages user and group information, priority information, etc., in units of users and groups, Enables priority delivery of content and access control. As shown in FIG. 5, in the embodiment in which the user management server (7) has priority information (75) corresponding to the user, the data processing unit (54) of the data processing relay device (5) Even if there is no priority delivery control by (), the delivery quality instruction is given to the relay unit (51) according to the default priority value of the user priority information (75) obtained from the user management server (7). Realize priority delivery.

  If delivery quality instruction information (66) is added to the data as a control instruction tag (60), the user priority information (75) specified in the user management server (7) is considered as described above. However, since the delivery is performed, more detailed and integrated processing can be performed.

  Furthermore, the directory server that manages the user group information of the client is shared with the database that manages the relay device, so that the relay device and the processing relay device can be managed together.

  In addition, by using communication traffic measurement technology in combination, dynamic quality control according to the network load becomes possible.

  By using the configuration of FIG. 1 or FIG. 33, a large-scale data distribution service by a data center becomes possible. For example, a game software maker prepares data in which license conditions and the like are added to the game software as control instruction tags. The data center performs distribution to users on behalf of the content provider while performing user management, billing management, trial period management, and license management according to the conditions. As a result, the content provider can save the trouble of license management and the like, and can distribute the content to many users with simple equipment.

  In addition, in the intra / extranet hosting service by the data center, if the network (Internet or dedicated line) connecting the data center and the company site is a low-bandwidth communication line, some users will receive a large amount of data. The problem arises that the other requests are hardly accepted.
