ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a managing system and a managing method of a mobile agent.
The mobile agent has aimed to perform appropriate processing in an appropriate place while accompanied by the movement of the code of the agent and the movement of data. The system construction with a high flexibility becomes possible by moving the agent, and continuing processing while communicating among the agents if necessary.
The application system created based on the mobile agent technology can be considered as a set of programs which activate in different computers. On the other hand, ones that mobility is given to the object based on a conventional object-oriented technology can be considered as an agent.
The mobile agent system is characterized with mobility. Therefore, the computer, which generates the agent, can be in a state of “Wait” until generated agent finish all work and return to the computer. That is, since it is unnecessary to activate the computer in the waiting state, the activation can be paused. However, in a case computer does not activate when the agent, who ended the round, intends to return the computer which generated the agent, a fact that the agent waits at the previous computer occurs, then, according to circumstances, the state, which the agents concentrates on a specific computer, occurs.
In the technology as mentioned above, when the agent cannot reach the final target computer since the agent moves not only data but also an own code to the itinerary, it is necessary to make the agent staying as it is. Therefore, there are disadvantages such as not being capable of activating a new agent with a small-scale computer which does not comprise the secondary memory or has the small memory capacity etc.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a managing system and a managing method of a mobile agent who can hold an agent temporarily without consuming a resource of a small-scale computer.
The managing system of the first mobile agent system according to the present invention wherein the mobile agent system comprises: a plurality of agent systems for generating an agent, executing the agent and performing a movement processing of the agent; at least one agent holding server having an agent holding table; and a network connected thereto, and wherein each of the plurality of agent systems has agent managing means to transfer the agent to the agent holding table of the agent holding server when the mobile agent system does not accept the agent in a case the agent is moved from the agent system under execution to the mobile agent system, and the agent holding server has server managing means to hold the agent in the agent managing table, and to move the agent when the mobile agent system can become accepting it. In the first agent managing system, each of the plurality of agent systems comprises: an agent transmitting and receiving section for transmitting and receiving the agent through the network; an agent storage section for holding an received agent; an agent manager for managing a generation of the agent, transmitting and receiving the agent, and an execution of the agent, and for moving the agent to the agent holding server specified by the agent when the mobile agent system can not accept the agent; and an agent execution section for executing a processing of the agent. A first method of managing the agent which has a plurality of agent systems for generating an agent, executing the agent and performing a movement processing of the agent; at least one agent holding server having an agent holding table; and a network connected thereto, according to the present invention comprises the steps of: transferring the agent to the agent holding table of the agent holding server when the mobile agent system does not accept the agent in a case the agent is moved from the agent system under execution to the mobile agent system; and moving the agent held in the agent managing table of the agent holding server to the mobile agent system when the mobile agent system can become acceptable.
By providing the agent holding server in the network of the mobile agent system, when the agent system, which is an itinerary of the agent, does not activate, the agent can be temporarily moved to the agent holding server. And, when the mobile agent system becomes in an activation state, by moving the agent, there is an advantage to be possible to make the processing of other agents executed preventing the agent on a small-scale computer from staying.
In the first agent managing system, each of the plurality of agent systems further comprises means for serializing and transferring the agent to the agent holding table of the agent holding server, when the mobile agent system can not accept the agent; and means for deserializing the serialized agent when the serialized agent serialized by the agent system is received through the agent holding server. In the first agent managing system, when the agent acceptance request is received from the mobile agent system, the agent holding server moves the agent to the mobile agent system stored in the agent holding table according to the request. In the method of managing the first agent, the steps of deactivating the own system until the agent issued by the agent system is processed by other agent systems connected with the network and returns; and confirming an existence of the agent moving to the own agent system for the agent holding server after the deactivated agent system starts, and requesting an itinerary of the agent are further provided. When the agent system which issues the agent deactivates and thereafter the system activates, it is possible to confirm whether the agent moving to an own agent system is returned to the agent holding server and request of movement of the agent. Therefore, the monitoring whether the agent system (That is, the target computer) with the agent holding server is activating becomes unnecessary.
In the first agent managing system, each of the plurality of agent systems further comprises means for serializing and transferring the agent to the agent holding table of the agent holding server, when the mobile agent system can not accept the agent; and means for deserializing the serialized agent when the serialized agent serialized by the agent system is received through the agent holding server. In the first method of managing the agent, the steps of: serializing the agent by the agent system under execution and transferring it to the agent holding table of the agent holding server when the mobile agent system can not accept the agent; and deserializing the agent by the mobile agent system, which receives the serialized agent from the agent holding server are further provided. Since only a state of the agent is serialized and moves to the agent holding server, and is deserialized when receiving a predetermined information, the consumption of the computer resource can be suppressed.
In the first agent managing system, the plural agent system further comprises: means for deactivating the system until the agent issued by the agent system is processed by other agent systems connected with the network, and returns; means for requesting an itinerary of the agent moving to an own agent system from the agent holding table of the agent holding server after the deactivated agent system activates the system; and means for deserializing the agent moving to the own agent system, which is moved from the agent holding server, and is serialized by another agent system while the agent system is in a deactivation state. In the first method of managing the agent, the steps of: deactivating the system until the agent issued by the agent system is processed by other agent systems connected with the network and then the agent returns; confirming an existence of the agent moving to the own agent system for the agent holding server after the deactivated agent system starts, and requesting an itinerary of the agent; and deserializing the agent moving to own agent system
