The present invention relates to a method for obtaining network resource information of an agent client, and more particularly, to obtain network resource information of other agent clients by exchanging network resource information between agent clients. It relates to an acquisition method.

Recently, as the amount of information on Internet sites increases, the necessity of providing a tool for searching for necessary information is increasing. So far, most sites use simple keyword-based search techniques, which are difficult to properly express the user's intentions, resulting in too many or unintended results, and users naturally search for information. I can't.

With recent advances in artificial intelligence, intelligent agents (or software agents) that can handle a variety of user needs (e.g. information retrieval, decision making, commodity price comparison, etc.) I am getting it. Here, the intelligent agent is a software that automatically solves a task desired by a user on behalf of the user, and is an autonomous process of performing a task on behalf of the user for a specific purpose.                         

The intelligent agent does not exist on its own but is part of or operates in an environment. In addition, the intelligent agent has a function of recognizing and responding to changes in the environment, learning based on experience, and co-operating with other agents to perform work.

The intelligent agent is classified into an internet agent, an interface agent, a mobile agent, and an electronic commerce agent according to a function to be performed.

The Internet agent is an application that resides in a server and accesses other Internet sites to obtain distributed online information. The interface agent is an application that executes a desired task through an application connected to a network. Is an application for moving itself to other servers for remote execution, and the e-commerce agent is an application for obtaining a product list information, etc. desired by a user from various Internet shopping malls.

On the other hand, the intelligent agent is the IP address of the server equipped with the intelligent agent to obtain distributed online information and product list information, run an application connected to the network, or move itself to another server, Network resource information such as stored data list, application program information, operating system environment (hereinafter referred to as service list), etc., should be recognized in advance.

1 is a block diagram of an agent network including an agent client and a resource server according to a conventional scheme.

As shown in FIG. 1, an agent network including an agent client and a resource server according to a conventional scheme includes a file server 10 for providing an agent application file and IP addresses of a plurality of agent clients 30 and 40. A resource server 20 for storing network resource information stored in each of the agent clients 30 and 40 and the online information and product list information distributed in the agent network, or an application connected to a network is executed. Or a plurality of agent clients (the first agent client 30 and the second agent client 40) for moving or moving itself to a server to which another agent client belongs.

2 is a flowchart illustrating a process of acquiring network resource information of an agent client according to a conventional scheme.

First, the first client agent 30 requests an agent application program to the file server 10 (200).

Then, the file server 10 transmits an agent application program to the first agent client 30 (201).

Then, the first agent client 30 downloads and installs an agent application program from the file server 10 (202). Here, the agent application program includes an IP address of the resource server 20.

Thereafter, the first agent client 30 accesses the resource server 20 through an IP address previously included in the agent application program (203).

Then, the resource server 20 requests network resource information from the first agent client 30 (204), and accordingly receives network resource information from the first agent client 30 (205). 1 The network resource information of the agent client 30 is registered (206).

Subsequently, the first agent client 30 requests network resource information of the second agent client 40 from the resource server 20 (207), and requests the second agent client 40 from the resource server 20. After receiving the network resource information (208), and accesses to the second agent client 40 via the received network resource information (209), and performs the service (210).

The prior art as described above provides network resource information of all agent clients to one resource server 20 to provide each agent client with a list of services owned by each agent client and location (IP address) information of each agent client. Manage it by storing it. In addition, each agent client accesses the resource server 20 each time in order to perform the service, checks network resource information of the agent client supporting the service, and then accesses the agent client.

However, the above-described conventional technology has a problem in that communication between agents is lost when a failure occurs in the resource server 20 that holds network resource information of all agent clients.

In addition, the prior art as described above does not provide mobility and independence to intelligent agents because all agent clients connect to other agent clients through the resource server 20.

The present invention has been proposed to solve the above problems, and provides a method for obtaining network resource information of an agent client by exchanging network resource information between agent clients to obtain network resource information of other agent clients. Its purpose is to.

The present invention for achieving the above object, the step of loading the network resource information that is previously stored in one agent client; A connection attempt step of the one agent client attempting to access a specific agent client through the loaded network resource information; A network resource information registration step of registering the loaded network resource information with the accessed specific agent client as the one agent client makes a connection with the specific agent client; The one agent client requesting and receiving network resource information of another agent client from the specific agent client; And updating, by the one agent client, the network resource information of the received other agent client in the loaded network resource information.

The above-mentioned objects, features and advantages will become more apparent from the following detailed description in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a diagram illustrating an embodiment of an agent network including an agent client and a file server to which the present invention is applied.

As shown in FIG. 3, an agent network including an agent client and a file server to which the present invention is applied includes a file server 10 storing an agent application file, and online information and products distributed in the agent network. A plurality of agent clients (first agent client 31, second agent client 32, for obtaining list information, running an application connected to a network, or moving itself to a server to which another agent client belongs) Third agent client 33 and fourth agent client 34).

The file server 10 is an additional component and provides an agent application file to each agent client 31 to 34. In addition, the agent clients 31 to 34 may download and install an agent application program from the file server 10 or read and install an agent application program stored in various recording media (eg, CD). have. In addition, the file server 10 may store only the minimum information, that is, the IP address of the agent client, in order to reduce the file capacity of the agent application program.

The agent clients 31 to 34 access the agent client through network resource information of another agent client included in the agent application program downloaded or read from the recording medium. That is, the agent clients 31 to 34 do not request an IP address of another agent to an intermediary server such as the resource server 20, but directly through the IP address of the agent included in the agent application program. It connects to agent client and performs the corresponding service.

Meanwhile, the agent clients 31 to 34 initially acquire network resource information of the agent client through the file server 10 or the recording medium, and then access other agent clients through the IP address currently held. Acquire IP addresses and service lists of other agent clients (agent clients newly joining the agent network).

Each of the agent clients 31 to 34 stores network resource information of another agent client as shown in Table 1 below. Hereinafter, after the first agent client 31 initially acquires network resource information of the second agent client 32 with reference to FIG. 4, the other agent clients (the third agent client 33 and the fourth agent client) A process of obtaining network resource information of 34) will be described in detail.

4 is a flowchart illustrating a process of acquiring network resource information of an agent client according to the present invention. Hereinafter, an agent application program is stored in the file server 10, and only the network resource information of the second agent client 32 is included in the agent application program, and the second agent client 32 is itself. It is assumed that network resource information of the third agent client 33 and the fourth agent client 34 is held.

First, the first agent client 31 downloads an agent application file from the file server 10 and installs an agent application program (400). In addition, the first agent client 31 may read and install an agent application program stored in a recording medium.

Thereafter, the first agent client 31 accesses the second agent client 32 through the IP address of the second agent client 32 previously stored in the agent application program (401).

Then, the second agent client 32 requests network resource information from the first agent client 31 (402).

Then, the first agent client 31 transmits its network resource information to the second agent client 32 (403).                     

Then, the second agent client 32 updates the network resource information of the received first agent client 31 in its network resource information (404). That is, the network resource information of the first agent client 31 is stored in the network resource information of the third agent client 33 and the fourth agent client 34 in which the network resource information of the second agent client 32 has been previously stored. It is updated to include.

Thereafter, the first agent client 31 requests network resource information from the second agent client 32 (405).

Then, the second agent client 32 transmits the network resource information owned by the second agent client 32 to the first agent client 31 (406).

Then, the first agent client 31 updates the received network resource information of the second agent client 32 by including it in the network resource information held by the first agent client 31 (407). That is, the network resource information of the third agent client 33 and the fourth agent client 34 is stored in the network resource information of the second agent client 32 in which the network resource information of the first agent client 31 has been previously stored. It is updated to include.

Thereafter, the first agent client 31 accesses the third agent client 33 through the IP address of the third agent client 33 among the updated network resource information (408). Thereafter, the processes '401' to '407' are performed between the first agent client 31 and the third agent client 33, so that the network resource information of the third agent client 33 is the first. The network resource information of the agent client 31, the second agent client 32, and the fourth agent client 34 is updated.

After the process '407', the fourth agent client 34 accesses the fourth agent client 34 through the IP address of the fourth agent client 34 among the network resource information updated by the first agent client 31 (409). Thereafter, a process of updating network resource information between the first agent client 31 and the fourth agent client 34 is performed, so that the network resource information of the fourth agent client 34 is converted into the first agent client 31. The network resource information of the second agent client 32 and the third agent client 33 is updated.

Meanwhile, the third agent client 33 performs the above process to obtain network resource information (IP address) of the fourth agent client 34 through the first agent client 31 to obtain a fourth agent client ( 34, the service can be performed (410).

5 is a flowchart illustrating an embodiment of a method for obtaining network resource information of an agent client according to the present invention.

First, the first agent client 31 loads stored network resource information (500).

Thereafter, the first agent client 31 attempts to connect to the second agent client 32 according to the agent client connection attempt order previously set (501). Here, the preset agent client connection attempt order is set according to an agent client order having a lot of network resource information or a recently connected agent client connection order.

Then, it is checked whether there is a response from the second agent client 32 which attempted the connection (502).

As a result of the check 502, if there is no response from the attempted agent client 32, the process proceeds to step '501' and attempts to connect to another agent client according to a preset agent client connection attempt sequence to see if there is a response. If there is a response from the second agent client 32 that attempted the connection, the first agent client 31 registers the loaded network resource information with the second agent client 32 (503). At this time, the first agent client 31 registers its network resource information with the second agent client 32, so that the second agent client 32 changes the network resource information of the first agent client 31 ( If the IP address is changed or the list of services owned is updated), it can be updated by reflecting it in its network resource information.

Thereafter, the first agent client 31 requests the second agent client 32 network resource information of the other agent client (504), and accordingly the network of another agent client from the second agent client 32 Receive resource information (505).

Thereafter, the first agent client 31 updates the received network resource information of the received other agent client in the loaded network resource information (506).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention as described above, by connecting to other agent clients through the network resource information of the other agent clients obtained by exchanging the network resource information between the agent clients, thereby preventing the communication between the agent clients is prevented, This not only provides mobility and identity to the agent client, but also maintains the latest network resource information of all agent clients at all times.
