The platform providing system proposed by the present invention aims to minimize communication costs between business objects such as various types of systems, applications, devices, users, etc. existing on the Internet business. To a collaborative computing platform. Hereinafter, the description of the present invention will be described in detail with reference to the application program among various business objects.

The platform providing system according to the present invention generates an intelligent mobile agent from the application program and executes it while migrating to several nodes. That is, the intelligent mobile agent generated in the platform providing system according to the present invention is an intelligent program that automatically performs a given task and brings back the result of the execution by moving to another node on the network to perform a given task. In order to facilitate understanding of the present invention, an overview of an intelligent mobile agent will be described first.

The intelligent mobile agent can select when and where to move and how long to continue at the destination, and comprises (1) executable code, (2) information data, and (3) attribute data.

First, (1) the executable code is the most essential part of the intelligent mobile agent corresponding to the actual application, and is described in a script-type language such as Java, telescript, safetel, Perl, and the like. The executable code may be executed by an interpreter after being written in a script form or an intermediate language in order to be executed regardless of the host type.

The mobile agent is a kind of program. Like other general programs, the mobile agent includes variables that can be changed according to the result of performing tasks performed in real time and functions that can actually execute the respective tasks. As a program, a mobile agent must process and maintain a task, a workflow, a processing method, and a result given to it through each variable. These variables become attributes of the mobile agent.

In an embodiment of the present invention, the intelligent mobile agent applies a code implementation in units of Java classes, and the agent is converted into a mobile object on a platform providing system according to the present invention, and is intended to move in the form of a byte stream. Sent to the destination node. In addition, when the agent moves the client system corresponding to each node on the platform providing system, initialization information or status information required during execution is also transmitted. The state information relates to the state value and the result information executed in the previous node, because the state information is required when the agent is executed in the node after moving to another node according to the routing policy.

Hereinafter, a platform providing system capable of executing the aforementioned intelligent mobile agent will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an overall platform providing system according to the present invention.

Referring to FIG. 1, a system according to the present invention includes a server system 100 and at least one client system 150, and the server system 100 and the client systems may be connected to each other through a network such as the Internet. Can be.

The server system 100 includes a client manager 110, a task recovery unit 120, an information store 130, an authentication processor 132, and a database 140 that manage path information and the like for each client system. .

The client manager 110 collects node information and related information about client systems corresponding to each node and stores them in a database, thereby storing each node to which the intelligent mobile agent is to move to each client system. Provides access to these fields, location and route settings.

The client manager 110 collects location information about the client system when the client system boots or logs in.

When the task recovery unit 120 transmits an object, such as an intelligent mobile agent, from the first client system to the second client system, the task recovery unit 120 does not connect to the second client system or transmits the object to the movable object for the intelligent mobile agent to be transmitted. When the hopping timeout time is set, the mobile object is managed until the second client system is connected. Here, the "movable object" is to convert the intelligent mobile agent to move to another client system to a form that can move to the client system corresponding to the destination, (1) intelligent mobile agent to move, (2) And a status value, (3) operation code, and (4) signal corresponding to the result of executing the intelligent mobile agent. Operation codes and signals will be described later.

That is, when the mobile object having the intelligent mobile agent is not properly transmitted to the client system corresponding to the destination to be transmitted, the task recovery unit of the server system corresponds to the client system corresponding to the destination to which the mobile object is to be transmitted and the mobile type. Store and manage objects in the information store. Next, when the client system logs in to the server system, the server system retransmits the object stored and managed through the task recovery unit.

Since the authentication processing unit 132 is the same as the function of the authentication processing unit 194 of the client system 150 to be described later, the description thereof will be omitted.

The client system 150 includes an agent transmission unit 160, an agent execution unit 170, an agent operation unit 180, an internal interface unit 190, an external interface unit 192, an authentication processing unit 194, and the like. The intelligent mobile agent may be created and executed or transmitted to another node.

In order to support mobility of the intelligent mobile agent, the agent transmitter 160 basically implements a transmission mechanism to convert a predetermined intelligent mobile agent into a mobile object. That is, the agent transmitter 160 is configured as an application program so that an application program constituting the intelligent mobile agent can be executed in a common environment such as a platform providing system according to the present invention without distinguishing wired or wireless Internet. After the mobile object is created from the intelligent mobile agent, it is converted into a byte stream for transmission to another client system according to the routing information, and then transmitted or executed in the client system. At this time, the agent transmission unit 160 stores a copy of the mobile object in a temporary storage inside before moving the mobile object to another client system, and then transmits it to the next client system. As such, a copy of the mobile object stored in the data repository is deleted at that time when a confirmation signal is sent from the next client system corresponding to the destination.

As described above, the intelligent mobile agent is composed of executable code, information data, and attribute data corresponding to an actual application program.

The agent transmitter 160 may include (1) broadcasting to move the application to all recipients at once, (2) multicasting to move the application only to a limited group, and (3) one. Unicasting, and (4) roaming for the application.

The roaming provides a multihop function that can recognize various types of failures occurring in a network, for example, a network failure, a congestion, a failure of a receiving system, or determine by itself. Further, in the worst case where the mobile object for the intelligent mobile agent cannot move to the node, the mobile object for the intelligent mobile agent is stored and managed in the information store in the server system by the task recovery unit of the server system. It must be passed to the node.

The agent manager 180 may exchange messages between the intelligent mobile agents, perform version control on the application program of the intelligent mobile agent, and download meta data.

The agent manager 180 is responsible for overall management of each client system. The agent manager 180 manages a user of the client system, provides an installation function, and manages various information about the same.

The agent execution unit 170 executes or inspects an intelligent mobile agent in a mobile object that has been moved from a client system corresponding to another node. That is, the agent executor stores the movable object for the intelligent mobile agent in a temporary storage for fault tolerant, and when the agent execution unit migrates from a client system corresponding to the previous node, sends a confirmation signal to the previous node by transferring the confirmation signal to the previous node. Delete the copy of the portable object stored in the temporary storage of the. In addition, the agent execution unit 170 reads the state value, executes the intelligent mobile agent, stores the state value again, and migrates to the client system corresponding to the next node.

If the agent is not executed by the agent executing unit 170 while the intelligent mobile agent is stopped or the power goes out, the intelligent mobile agents are executed again after the login is executed.

The internal interface 190 transmits or transmits necessary data when an intelligent mobile agent or an interaction between a client system and a server system is required or when an application of the intelligent mobile agent requires the use of data on another node. To receive it. That is, the internal interface unit sets a path and a rule for accessing the corresponding node in order to transmit or receive data and access the corresponding node.

Such an internal interface 190 is used when information collection and exchange are needed for cooperation and meeting between agents (for example, node loss notification, rerouting, provision of recovery measures, etc.).

The external interface unit 192 is for providing data required by application programs on each client system, and is an interface unit for connecting to an external database of an external system rather than the system according to the present invention. The external interface unit 192 is an interface required for smooth connection between application programs provided in an external system and the platform providing system according to the present invention.

The authentication processing unit 194 is provided for information protection and security authentication between nodes, and SSL is set for information security and PKI is set for information authentication. The first time that you migrate to that node, the session value is created based on the time. When you migrate to another node, the sending node will generate SSL and PKI augmented values in the initial session value. Extract the SSL, PKI values.

Hereinafter, a method of implementing various functions according to the platform providing system having the above-described configuration will be described in detail with reference to FIGS. 2 to 10.
