Description

[0001]
BACKGROUND OF THE INVENTION
The present invention, for example, distributes stock price information and financial information to a large number of connected computers at all times, or performs a certain information processing in response to a request, and then distributes the information to a large number of computers (clients, The present invention relates to an information distribution and response system that is a network to which a server is connected, mediates requests and services between computers, and responds with predetermined information to certain requests.
[0002]
In particular, a client simply requests a desired information without being aware of a specific server, and a predetermined server executes information processing and information transmission corresponding to the request, and information on the execution result is returned to the client. The present invention relates to an “information distribution response system” in which a large number of computers participate.
[0003]
It should be noted that the term “information distribution response system in which a large number of computers participate” is used here to represent a specific image of the system, and not only “large numbers” but also “plurality” of computers are connected. Any system can be used.
[0004]
In addition, as described later, according to the system of the present invention, the computer is assumed to “join”. The computer registers a service that can be performed by the computer and operates as a client. This is because it becomes a server that provides.
[0005]
[Prior art]
2. Description of the Related Art A network system that distributes stock price information and financial information that is currently widely used to connected computers is a client server system that includes a client that issues a predetermined request and a server that provides the predetermined information in response to the client's request It was made up of.
[0006]
In this conventional client-server system, the client is aware of the location of the server and tries to connect directly to the server for communication. In other words, conventionally, when a client issues a request, data specifying the communication partner server is included in the command statement of the request, and then the request is transmitted to the server to obtain an answer.
[0007]
For this reason, in the conventional client-server system, the user cannot obtain desired information unless he / she is well aware of the network environment such as server arrangement. Further, even for a user who is familiar with the network environment, the procedure for creating a request sentence or a program including the request sentence is complicated.
[0008]
Specifying this server is not limited to a simple request statement, but is also the same in network programming in which a predetermined computer operates as a client server system. That is, the software program for operating the client server system is strongly dependent on the network environment.
[0009]
For this reason, in such a network program that relies heavily on the network environment, when the configuration of the server or application software is changed, the program is forced to be overhauled. This is extremely inconvenient in the current situation where it is necessary to flexibly change the arrangement of servers and clients or upgrade software.
[0010]
On the other hand, in order to improve the complexity of the request sentence of the client server system, a concept (standard, interface) called “agent” has recently been proposed.
[0011]
This agent performs necessary procedures as a user's “agent” and is characterized by having knowledge necessary for processing. For example, in a network that reserves a ticket with an agent, the user does not specify a specific server, but only enters the desired ticket condition, and the agent searches for the server corresponding to the request, and the job ( Transfer ticket reservation process).
[0012]
That is, the agent transfers information exchanged between a plurality of open systems (each of which has a client and a server as systems) as a unified “work specification” between the systems. This work specification usually contains the following information:
[0013]
(1) Identifier of job information object such as system name and job name
(2) Information about access authority such as reference to and execution of job information object
(3) Information about the job processing result report destination and its content specifications
(4) Job processing request destination system name, information on transfer and operation
(5) Cooperative processing information specifying the processing to be performed next
In addition to the object-oriented framework, the agent has the knowledge to properly use data and procedures, and user requests are referred to as “work specifications”, and user requests are transferred as jobs between open systems (clients and servers). To do.
[0014]
This "agent" concept has been studied as a user interface, according to which a job is entered on one system (client), the data necessary to execute the job is collected from another system, and further The job can be executed on another system.
[0015]
[Problems to be solved by the invention]
However, the above "agent" has not yet been put into practical use, it has only been proposed as a concept of data and procedure transfer standards, and no definite thing has been realized as a concrete means of the system. .
[0016]
In addition, the “agent” still depends on the network environment, as is clear from the fact that the “work specification” includes information such as the job processing result report destination and the job processing request destination.
[0017]
For this reason, when rearranging servers and application software, the agent software program had to be reviewed. As a result, the network environment is inevitably fixed, and it has not been possible to flexibly cope with the entry of a new system (client, server) or the deletion of an existing system (client, server).
[0018]
In addition, since the data transfer, operation, and format must be unified, the processing is complicated, and it has been impossible to flexibly incorporate various existing systems.
[0019]
Furthermore, in the conventional client-server system including the agent, the server that performs processing is fixed, and the computer's ability to perform various types of processing cannot be fully utilized.
[0020]
Therefore, the problem to be solved by the present invention is to allow changes in the network environment such as rearrangement of servers and application means, and to maximize the ability of computers connected to the network by uniform and simple requests. The object is to provide an "information distribution response system in which a large number of computers participate" that can obtain the processing results used.
[0021]

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described below with reference to the accompanying drawings.
First, for easy understanding, an example of a physical system configuration of the information distribution response system according to the present invention will be shown and described.
[0055]
FIG. 1 shows a physical configuration example of an information distribution response system according to the present invention. The information distribution / response system in FIG. 1 includes two workstations (WS1, WS2) and four personal computers (PC1 to PC4). In addition, it is assumed that an external network (NET1) is also connected to this system so as to be accessible.
[0056]
It is assumed that each workstation (WS1, WS2) and personal computer (PC1 to PC4) have application means (indicated by reference sign AP in the figure and surrounded by a square frame).
[0057]
It is assumed that the external network (NET1) has an interface between the application means and the information distribution response system according to the present invention.
[0058]
Here, the application means refers to information processing means that specializes functions for a specific purpose. The application means may be hardware that performs fixed processing, but is preferably a computer processing device that is controlled by predetermined application software and performs predetermined processing at a certain point in time.
[0059]
The application means may comprise an object by object-oriented programming, but the application means itself is a means controlled by a procedural program and has an object-oriented programming interface with the information distribution response system according to the present invention. It may be a thing.
[0060]
Here, an object is classified according to a certain attribute, and data and a procedure are integrated. The object has the following characteristics.
(1) Objects (class objects) having the same attribute basically have the same method (means for performing predetermined processing).
(2) Attributes and methods of a class object can be inherited by other class objects.
(3) It is possible to request another object to perform processing using a method possessed by the object.
[0061]
The “object” in this specification includes hardware for executing the object in addition to software that integrates the data and procedure.
[0062]
That is, each processing means (core node, management section, processing means of each management section, or application means) constituting the system of the present invention can be expressed by the above object, and each processing means or management section is an object. Thus, the system of the present invention can flexibly cope with various processes. In the following embodiments, each processing means constituting the system is assumed to be an “object”. However, this does not mean that the present invention is limited to an object-oriented framework. That is, the same function as the object may be realized by a computer controlled by a normal procedural program.
[0063]
In the configuration example of FIG. 1, the personal computer PC1 is an object that operates as an inquiry response type server, the personal computer PC2 is an object that operates as a transmission type server, the personal computer PC3 is an object that operates as a client, and the personal computer PC4 is also operated as a client. Each object.
[0064]
Here, “inquiry-response type server” refers to a server that performs predetermined information processing in response to a request (inquiry request) from a client and responds. “One-side transmission type server” refers to a request from a client. A server that transmits predetermined information in response to (one-side transmission request). Servers in a client server system can be normally divided into these two types of servers.
[0065]
The workstation WS1 has two objects that operate as inquiry response servers and objects that operate as core nodes. The workstation WS2 has an object that operates as a one-side transmission server. Further, the application means on the external network NET1 is grasped here as an object that operates as a client or a server.
[0066]
Note that each of the inquiry response type server, the one-side transmission type server, and the client is an “application unit” in this specification.
[0067]
Each object has an interface with an information distribution response system (abbreviated as “IDP” in the description of this embodiment) (denoted as IDP API in FIG. 1).
[0068]
In this embodiment, one core node is generated when the system is started. In the example of FIG. 1, it is generated in the workstation WS1, but this is not fixed, and may be generated in a suitable workstation by the system at startup. Further, objects below the core node described later may be generated by being distributed to a plurality of workstations. A plurality of core nodes may be generated for each service ID described later. In this case, different information distribution responses can be performed by the core node.
[0069]
For this core node, each personal computer and workstation object has a "connection". Here, the connection is a path for sending a predetermined message between objects to a partner object. This message can request processing of a predetermined method to the partner object. In other words, each object can request other objects to perform predetermined processing and information distribution through “connection”.
[0070]
As shown in FIG. 1, in the information distribution response system of the present invention, all servers and clients are connected to the core node by connections. This means that the core node mediates requests and information transmission between all objects (server and client).
[0071]
The information distribution response system in FIG. 1 has two types of inquiry response type servers. These inquiry response services are classified into “inquiry response service ID 100” and “inquiry response service ID 200”, respectively, according to the content of the inquiry response service. The inquiry response type server that performs the inquiry response service ID 100 exists in the personal computer PC1, while the inquiry response type server that performs the inquiry response service ID 200 exists in the workstation WS1.
[0072]
Here, the service ID is an identifier that identifies the inquiry response service or the one-side transmission service according to the information content, data type, etc., and is specified by a number or the like.
[0073]
The workstation WS1 has two inquiry response type servers that perform the same inquiry response service ID 100. These inquiry response type servers that perform the same inquiry response service are referred to as “nodes” of the inquiry response service ID 100. As in the example of FIG. 1, a plurality of nodes may exist for the same service ID. Physically, a node means a device (application means) existing on the network.
[0074]
The information distribution response system in FIG. 1 has two types of one-side transmission type servers. These one transmission services are classified into “one transmission service ID 150” and “one transmission service ID 250”, respectively. On the other hand, the one transmission type server that performs the transmission service ID 150 exists in the workstation WS2, while the one transmission type server that performs the transmission service ID 250 exists in the personal computer PC2. Similar to the inquiry response type server, a plurality of one-side transmission type servers can exist in the same computer. Similarly to the inquiry response service, there are a plurality of “nodes” that perform the one transmission service for the same one transmission service ID.
[0075]
It should be noted here that according to the present invention, each server is not recognized as a specific physical device, but as a service ID classified according to the content of the service.
[0076]
That is, as will be described later, in the present invention, a computer (regardless of a server and a client) connected to a system registers information that can be provided and the contents of information that can be provided in advance as a service ID in the core node. The client designates a predetermined service ID to the core node and issues a request, and the core node searches for a server that provides the service ID and transfers the job.
[0077]
By recognizing a server as a service ID in this way, it becomes possible to deal with physical server relocation and the like only by changing the registered contents of the core node.
[0078]
In addition, a computer that is a client is requested to perform a predetermined process and operates as a server. On the other hand, a server can request a service of another server as a client. In other words, a computer connected to the system registers a service that it can provide in advance, and when requested for that service, it operates as a server, but it is not fixed as a server. You can also request services from other servers. Thereby, according to this system, the capability of the computer which operates as a client can also be used, and the capability of all the computers connected to the system can be utilized.
[0079]
In the information distribution response system of FIG. 1, a server and a client that perform two types of inquiry response services (ID100, ID200) and two types of one-side transmission services (ID150, ID250) have connections to the core node. With this configuration, the personal computers PC3 and PC4 that are clients can receive four types of services, that is, service IDs 100, 200, 150, and 250, through the core node.
[0080]
The workstation WS2 can also receive services from other servers as a client from time to time.
[0081]
Next, the configuration of the core node which is the central part of the present invention will be described below.
FIG. 2 shows the structure of the class object of the core node. In FIG. 2, each object is surrounded by a square line, the object name is shown in the upper part, the attribute is shown in the middle part, and the method of the object is shown in the lower part.
[0082]
As shown in FIG. 2, the core node denoted as a whole by reference numeral 1 includes a main control unit 2, an application means management unit 3, a one-side transmission type server management unit 4, an inquiry request management unit 5, and a one-side transmission request management unit. 6 and.
[0083]
The application means management unit 3 includes application information management means 3a and application management table management means 3b.
[0084]
On the other hand, the transmission type server management unit 4 includes a server node ID management unit 4a, a server service ID management unit 4b, and a server information list management unit 4c.
[0085]
The inquiry request management unit 5 includes reply watcher means 5a, request queue management means 5b, and request queue manager means 5c. The converter means 5d is added in another embodiment. An embodiment having the converter means 5d will be further described later.
[0086]
On the other hand, the transmission request management unit 6 includes request element management means 6a, request information management means 6b, request information list management means 6c, and data dispatcher means 6d. The converter means 6e is added in another embodiment. An embodiment having the converter means 6e will be further described later.
[0087]
The application information management means 3a is means for managing channel information and information related to application means for each channel that maintains communication between a predetermined request and application means that processes the request. That is, in the system of the present invention, a predetermined server (application means) processes and distributes information for a predetermined request, but it is necessary to maintain a communication port for the information flow. The communication point of information flow is a channel.
[0088]
The application information management means 3a manages information on application means for providing services for each channel (location of application means, etc.) and other channel information (for example, channel identifiers, etc.).
[0089]
There is one application management table management means 3b in the entire system, which has an application management table and manages the application information management means 3a. Here, “management” between objects means, for example, that the application management table management unit 3b requests the application information management unit 3a to search information on a predetermined application unit and obtain a response. Say. The same applies to “management” between objects.
[0090]
The application management table is a table in which information (application information) of each application means connected to the information distribution response system is registered. The application management table registers information of all application means regardless of the client and the server. Here, the application information registered in the application management table is information for identifying each application means, for example, a service ID for identifying the contents of a service provided by the application means, the location of the application means, and the like.
[0091]
The server node ID managing means 4a exists for each transmission node that transmits information for each transmission service ID, and manages information on the transmission node. That is, the one-side transmission service ID may have a plurality of one-side transmission nodes, but the server node ID management unit 4a manages node information such as the location of each one-transmission node.
[0092]
One server service ID management unit 4b exists for each transmission service ID, and manages the server node ID management unit 4a.
[0093]
One server information list management unit 4c exists in all systems, has a server information list, and manages the server service ID management unit 4b. The server information list is a list in which all one-side transmission servers are registered.
[0094]
The reply watcher unit 5a is a unit that exists for each inquiry request ID, registers information of application units waiting for a response, monitors the response, and transmits response data when there is a response. The request ID is an identifier assigned to each request in order to specify the request.
[0095]
The request queue management means 5b exists for each inquiry response service ID, manages information of an inquiry response type server that performs the corresponding inquiry response service, and holds inquiry request inquiry data.
[0096]
That is, when there is an inquiry request, the request queue management means 5b searches for an inquiry response type server that performs the corresponding inquiry response service, and asks the inquiry data (information of the application means that made the inquiry and processing). The original data) is transferred and the inquiry data is registered until a response is received.
[0097]
The request queue manager 5c exists for each inquiry response service ID, and manages the request queue manager 5b.
[0098]
The request element management means 6a exists for each subkey of one transmission request, and stores and manages subkey information. Here, the “sub key” is a partial key that constitutes a key that is designated when a transmission request is made on one side, and is a key for filtering transmission data on the other side. For example, when requesting distribution of stock price information, a certain brand may be designated or a certain period may be designated. In this case, the key for designating a fixed brand is a subkey, and the request element management means 6a manages the contents (subkey information) indicated by the subkey.
[0099]
The request information management means 6b exists for each request content of one transmission request, and manages the request element management means 6a. Here, the request content of the one-side transmission request is the content of the one-side transmission request specified by the combination of the sub keys. For example, in the previous example, the stock price information is specified as “how many brands and how many periods”. Even the same one transmission request has a plurality of request contents depending on the contents.
[0100]
The request information list management means 6c exists for each transmission service ID, and manages the request information management means 6b. The one-side transmission service ID is an identifier indicating one-side transmission service of stock price information in the above example.
[0101]
One data dispatcher means 6d exists in the entire system, manages the request information list management means 6c, and transmits transmission data to the application means.
[0102]
The above is the description of each constituent unit of the present embodiment. Next, the operation of each constituent unit in the inquiry response service and the one-side transmission service will be described below. In the following description, the relationship between the constituent means becomes more apparent by referring to the configuration of the information distribution response system shown in FIG.
[0103]
First, to configure the information distribution and response system of the present invention, a computer must be connected to the system. More precisely in accordance with the configuration of the present invention, application means must be connected to the system. FIG. 3 shows the flow of processing for connecting the application means. In the flowchart of FIG. 3, the processing means for performing the processing of each processing step is shown in parentheses.
[0104]
As shown in FIG. 3, in order to connect the application means to the information distribution response system of the present invention, the computer requesting connection requests the main control unit 2 of the core node 1 to connect the application means (step S100).
[0105]
Receiving this connection request event, the main control section 2 generates an event for connecting the application means to the application means connection acceptance channel (step S110). This event is processed as follows.
[0106]
First, a new application information management unit 3a is created for the application unit that requests connection, and channel information, information about the application unit, and the like are registered (step S120).
[0107]
Next, the new application information management means 3a is registered in the application management table (step S130).
[0108]
The above is the process for connecting the application means, but the application means that provides the service must be declared as a server. The flow of server declaration processing is shown in FIG. In the flowchart of FIG. 4, the processing means for performing the processing of each processing step is shown in parentheses.
[0109]
As shown in FIG. 4, in order for the application means to provide a service as a server, it must be declared to the main control unit 2 of the core node 1 as a server (step S200).
[0110]
In response to the server declaration event from the application means, the main control section 2 creates application information management means 3a for the application means (step S210).
[0111]
Next, depending on the type of service provided by the application means, either the following processing as a one-side transmission type server or processing as an inquiry response type server is performed.
[0112]
If the server that made the server declaration is a one-side transmission type server, first, the server information list management means 4c registers the server information in the server information list (step S220).
[0113]
Next, the server information list management means 4c searches for the server service ID management means 4b that is the same as the service ID of the server. If there is no corresponding server service ID management means 4b, a new server service ID management means 4b is created (step S230).
[0114]
Next, the server service ID management means 4b searched or created in step S230 creates a server node ID management means 4a for the declared server (step S240).
[0115]
Finally, the server information list management unit 4c sets a transmission start flag for the server (step S250).
[0116]
If the server that made the server declaration is an inquiry response type server, the corresponding application information management means 3a has already been created in step S210, and therefore the inquiry response type server is registered in the inquiry request management unit 5 here.
[0117]
First, the application information management means 3a searches for a request queue manager means 5c having the same inquiry response service ID (step S260). If there is no request queue manager means 5c having the same inquiry response service ID, it is newly created.
[0118]
Next, the application information management means 3a registers the information of the server making the server declaration in the request queue manager means 5c searched or created in step S260 (step S270).
[0119]
Finally, the request queue manager 5c acquires the request queue manager 5b, and registers the server declaring the server as an inquiry response type server (node) that provides an inquiry response service corresponding to the inquiry response service ID. (Step S280). Here, “acquisition” means that a predetermined object is searched and various messages can be sent through the connection.
[0120]
The above is a description of the server declaration and its processing. The information distribution response system in which the application means are connected as described above and the application means that operates as the server is registered as the server is described in the following. Distribute and respond. In the following description, this information distribution and response will be described separately.
[0121]
First, an information response, that is, an inquiry response service will be described. The inquiry response service includes transmission of an inquiry request from the client to the inquiry response type server and transmission of a response from the inquiry response type server to the client. These transmissions are all performed via the core node 1.
[0122]
FIG. 5 shows a flow of transmission of an inquiry request from the client to the inquiry response type server. In the flowchart of FIG. 5, the processing means for performing the processing of each processing step is shown in parentheses.
[0123]
The inquiry request is issued from the client, and is input as an inquiry event to the main control unit 2 of the core node 1 as shown in the beginning of FIG. 5 (step S300).
[0124]
Receiving the inquiry event, the main control unit 2 generates application information management means 3a for each channel (step S310).
[0125]
Next, the application information management means 3a generated in step S310 obtains the request queue manager means 5c of the inquiry response service ID corresponding to the inquiry request (step S320).
[0126]
The request queue manager 5c acquired in step S320 acquires the request queue manager 5b having the same inquiry response service ID (step S330). The request queue manager means 5c passes information (inquiry data or information on the inquiry source application means) related to the inquiry request to the acquired request queue management means 5b (step S340).
[0127]
The request queue management means 5b registers information related to the inquiry request in the request queue, that is, the inquiry request queue (step S350).
[0128]
Next, the request queue management means 5b acquires the reply watcher means 5a, and registers the application means of the inquiry request source as a response waiting application means (step S360).
[0129]
The reply watcher unit 5a acquired in step S360 sets a response wait timer for the inquiry request and monitors the response (step S370).
[0130]
Next, the request queue management means 5b searches for an inquiry response type server (node) that performs an inquiry response service in accordance with a predetermined processing priority, and has the highest processing priority among the inquiry response type servers that can be processed. The application information management means 3a of the high inquiry response type server is acquired (step S380).
[0131]
Next, the application information management means 3a transmits inquiry data to the searched inquiry response type server (step S390). As a result, the inquiry request and inquiry data are processed by a predetermined inquiry response type server.
[0132]
The above is the transmission of the inquiry request from the client to the inquiry response type server. Next, the transmission of the response from the inquiry response type server to the client after the inquiry response processing will be described.
[0133]
FIG. 6 shows a flow of transmission of a response from the inquiry response type server to the client. In the flowchart of FIG. 6, the processing means for performing the processing of each processing step is shown in parentheses as in FIG.
[0134]
The response transmission event is issued from the inquiry response type server that performed the processing, and is input to the main control unit 2 of the core node 1 as shown at the beginning of FIG. 6 (step S400).
[0135]
Receiving the response transmission event, the main control unit 2 acquires the application information management means 3a corresponding to the inquiry response type server that responds (step S410).
[0136]
Next, the application information management unit 3a acquired in step S410 acquires the request queue manager unit 5c of the corresponding inquiry response service ID (step S420).
[0137]
The request queue manager 5c acquired in step S420 acquires the request queue manager 5b having the same inquiry response service ID (step S430).
[0138]
The request queue management means 5b acquired in step S430 deletes the inquiry request that has been inquired from the request queue (step S440).
[0139]
Next, the reply watcher means 5a deletes the data related to the application means (client) of the inquiry request source from the data of the response waiting application means (step S450).
[0140]
The inquiry request is deleted from the inquiry request management unit 5 through the processes in steps S420 to S450 described above.
[0141]
Next, the reply watcher means 5a accesses the application management table management means 3b and acquires the application management table management means 3b (step S460).
[0142]
The application management table management means 3b acquires the corresponding application information management means 3a from the information of the inquiry response type server, and the reply watcher means 5a obtains the information of the request source application means by the application information management means 3a. (Step S470).
[0143]
Finally, the reply watcher unit 5a transmits the response data to the request source application unit obtained as described above (step S480).
[0144]
The above is the processing flow of the core node 1 regarding the transmission of the inquiry request of the inquiry response service and the return of response data. Next, the processing of the core node 1 related to the request and transmission of the one-side transmission service will be described.
[0145]
On the other hand, the transmission service is divided into transmission of one transmission request from the client to the one transmission type server and transmission of one transmission data from the one transmission type server to the client, similarly to the inquiry response service. All of these transmissions are also performed via the core node 1.
[0146]
FIG. 7 shows a flow of transmission of a one-side transmission request from the client to the one-side transmission type server. In the flowchart of FIG. 7, the processing means for performing the processing of each processing step is shown in parentheses.
[0147]
On the other hand, the transmission request is issued from the client and is input as an event of one transmission request to the main control unit 2 of the core node 1 as shown in the beginning of FIG. 7 (step S500).
[0148]
The main control unit 2 that has received the one transmission request event generates application information management means 3a for each channel (step S510).
[0149]
Next, the application information management means 3a obtained in step S510 obtains the data dispatcher means 6d to check whether or not the same one transmission service is performed (step S520).
[0150]
The acquired data dispatcher means 6d searches the requested information list management means 6c having the same ID as the requested one-side transmission service ID (step S530). If the request information list management means 6c having the same ID does not exist, it is newly generated.
[0151]
Next, the searched or generated request information list management means 6c searches for the request information management means 6b whose request contents match (step S540). If there is no request information management means 6b having the same request content, it is newly generated.
[0152]
Here, the request content may include various conditions for the data to be distributed even in the same one transmission service ID, and in this case, it is a one transmission request that is distinguished depending on the conditions of the distribution data. . The contents of the request are one-side transmission request keys.
[0153]
Next, the retrieved or generated request information management means 6b registers information on subkeys constituting the request key in the request element management means 6a (step S550).
[0154]
Next, the request information management unit 6b generates a request source application unit management unit 7 and registers information of the request source application unit (step S560).
[0155]
Finally, the application information management unit 3a generated in step S510 transmits one transmission request to the one transmission type server corresponding to the request (step S570).
[0156]
The above is the transmission of the one transmission request from the client to the one transmission type server. Next, the transmission of the one transmission data from the one transmission type server to the client will be described.
[0157]
FIG. 8 shows a flow of transmission of one-side transmission data from the one-side transmission type server to the client. In the flowchart of FIG. 8, the processing means for performing the processing of each processing step is shown in parentheses as in FIG.
[0158]
On the other hand, an event of transmission of transmission data is emitted from the one transmission type server that distributes and is input to the main control unit 2 of the core node 1 as shown at the beginning of FIG. 8 (step S600).
[0159]
Receiving the transmission event, the main control unit 2 acquires the application information management means 3a corresponding to the one-side transmission type server (step S610).
[0160]
Next, the application information management unit 3a obtained in step S610 acquires the data dispatcher unit 6d to search for the request source client (step S620).
[0161]
The acquired data dispatcher means 6d searches for the request information list management means 6c having the same ID as the transmission service ID requested to be distributed (step S630).
[0162]
Next, the data dispatcher means 6d searches for the request information management means 6b whose request contents match through the request information list management means 6c (step S640).
[0163]
If there is a request information management unit 6b that matches the request contents, the request information management unit 6b acquires the request source application unit management unit 7 and acquires information on the request transmission source application unit (step S650). .
[0164]
Finally, the data dispatcher means 6d transmits one transmission data to the request transmission source application means obtained in step S650 (step S660).
[0165]
The above is the processing flow of the core node 1 regarding the transmission of the one transmission request and the distribution of the one transmission data in the one transmission service.
[0166]
As is clear from the description of FIGS. 1 to 8, the information distribution response system according to the present invention does not communicate directly between the client and the server, but registers the service provided by the server as a service ID in the core node. Specifies a service ID to be used and makes an inquiry to the core node, and the core node requests the server providing the service ID to provide the service. The server also sends data to the core node instead of sending the data directly to the client, and the core node distributes it to the client requesting the service ID.
[0167]
As described above, the server is managed by the service ID, and this management is performed by the core node, so that by changing the service ID, a large number of servers can be connected and a system that provides a large number of services can be obtained. In addition, the server can be extended easily by making a server declaration without changing the previous system.
[0168]
In addition, by making a request with the service ID in this way, it is possible to unify the data acquisition method from the system and to construct a user-friendly system.
[0169]
In terms of programming that constitutes the client server system, the program of the node that constitutes the system does not depend on the environment of the system such as the arrangement of the server, so that application means can be made into parts and components.
[0170]
Furthermore, a computer connected to the information distribution response system registers a service (information processing or data distribution) that can be provided as a service ID, and provides the service when requested. As a client, it is possible to request a service from another server. As a result, the information distribution response system according to the present invention can be utilized without leaving the processing capacity of the existing computer, and an extremely efficient information processing system can be obtained.
[0171]
Further, if only one transmission service ID and the content of the transmission data are the same, a plurality of clients can enjoy one single transmission service at the same time. This makes it possible to distribute information that is expected to be used in a very efficient manner.
[0172]
Further, the request queue management means 5b has information of a plurality of inquiry response type servers that provide the same inquiry response service. The request queue management means 5b checks these inquiry response type servers when sending a predetermined inquiry request, and requests the server having the highest processing priority order among the processable inquiry response type servers. . As a result, the load on the information distribution and response system is averagely distributed, the hardware resources of the system can be used efficiently, and the possibility that the function of the system is impaired due to the concentration of processing on a specific server may be reduced. it can.
[0173]
The server load balancing function is not an essential component of the information distribution response system of the present invention, and may be a system that does not have this function.
[0174]
Next, a modified example (another embodiment) of the above embodiment will be described below.
In the above embodiment, the information distribution response system (the claims 1 to 13 of the present application) that provides both the one-side transmission service and the inquiry response service has been described. However, it is of course possible to configure an information distribution response system that provides only a transmission service (claims 14 to 23 of the present application) or an information distribution response system that provides only an inquiry response service (claims 24 to 33 of the present application).
[0175]
In the above embodiment, the service ID has been described on the assumption that the service ID is classified according to the content of the provided service and the type of data. Here, the type of data refers to, for example, text data or data specifying specific application software (OS, word processor, spreadsheet, database, etc.).
[0176]
That is, in the above-described embodiment, the request specifies predetermined information content and its data format by the service ID, and obtains corresponding information.
[0177]
However, according to the present invention, the difference between the application software can be absorbed by providing the converter means 5d and the converter means 6e shown in FIG.
[0178]
In this case, the service ID is simply classified according to the service content, and the client designates the content of information to be acquired and the service ID, and further specifies the type of data to be acquired and issues a request. The converter means 5d and the converter means 6e convert the data provided by the server into a data format desired by the client, and the reply watcher means 5a and the data dispatcher means 6d return the converted data to the client.
[0179]
By doing so, data processed by other application software can be used, and an information distribution response system with low dependency on the OS and high efficiency can be obtained.
[0180]
In the description of the above embodiment, the events sent to the main control unit of the core node are all sent from the client or the server. However, as shown in FIG. 1, the information distribution response system of the present invention can also process events from other networks.
[0181]
As a result, the information distribution response system of the present invention is not configured by only a single network, but the network and the network form an information distribution response system in a complex manner. Information can be acquired.
[0182]
The information distribution response system of the present invention includes a case where the information distribution response system is a complex system incorporating the plurality of networks.
[0183]
【The invention's effect】
As is clear from the above description, according to the information distribution response system of the present invention, the server is identified by the service ID, the client issues a request by specifying a predetermined service ID, and the core node mediates the request. Processing is requested to a predetermined server, and a response from the server is returned to the requesting client. As a result, the program for controlling the client and the server becomes independent from the network environment, and changes in the network environment such as server rearrangement and expansion can be absorbed.
[0184]
In addition, when a user acquires data, the user can obtain desired information from the information distribution response system simply by specifying the desired data or service. As a result, a system that realizes simple data acquisition can be provided.
[0185]
Furthermore, since the server is not fixed as a server and can receive services of other servers as a client, the ability of the entire computer connected to the system can be fully utilized. As a result, an information distribution / response system with extremely high utilization efficiency can be obtained.
[0186]
Further, by combining the networks in a complex manner, it is possible to provide an information distribution response system that performs extremely wide information processing and information distribution.
