Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is elaborated:
The present invention is the improvement to mobile agent migration mechanism, by moving cache management person AMCM(Agent Migration Cash Manager to increasing a mobile agent on mobile agent platform, be called for short AMCM), after mobile agent moves unsuccessfully, give AMCM to preserve packaged mobile agent information, when same mobile agent is asked after migration again, by main body mobile management person (the Agent Mobility Manager on AMCM and local mobile agent platform, be called for short AMM) mutual, packaged message is sent to object website.
one, mobile agent platform
Mobile agent platform model of the present invention, as shown in Figure 1, is made up of following components:
1, message delivery system (Message Transport System): be a component software of controlling entire message exchange (comprise and be sent to remote platform and send to the machine from remote platform) in platform also referred to as Agent communication channel (Agent Communication Channel is called for short ACC).
2, mobile agent management system (Agent Management System, be called for short AMS): be one to the mobile agent platform mobile agent of controlling that exercises supervision.On a platform, only have an AMS to exist.AMS provides life cycle service, is safeguarding the catalogue (Directory of Agent Identifiers is called for short AID) of a mobile agent identity and the state of mobile agent.Each mobile agent must register to obtain an effective AID to AMS.
3, LIST SERVER (Directory Facilitator is called for short DF): be a mobile agent that mobile agent communication directory service in platform is provided.In platform, DF is equivalent to a LIST SERVER, and each mobile agent that service is provided can be registered its service to DF, and other mobile agent can be inquired about such service from DF, also can subscribe to this class service.
4, main body mobile management person (Agent Mobility Manager is called for short AMM): be a mobile agent that migration service is provided in platform.AMS on local platform and the AMS on the platform of strange land carry out alternately, thereby help this mobile agent to move from local platform migration to strange land platform.
5, mobile agent migration cache management person AMCM(Agent Migration Cash Manager, is called for short AMCM): be a mobile agent that the service of migration buffer memory is provided in platform.Detailed workflow sees below literary composition.
In the time that a mobile agent platform starts, AMS, AMM, AMCM and DF are created immediately, and ACC module is set to allow message communicating.
Owing to only having a java application, therefore on every main frame, only move a Java Virtual Machine.Each Java Virtual Machine is one to be carried out the basic container of a complete runtime environment is provided for mobile agent, and allows multiple mobile agents on a main frame, to carry out simultaneously.
Primary tank is the container of AMS, AMM, AMCM and DF mobile agent resident and that used by mobile agent platform inside.Other mobile agent container is connected to primary tank, and provides a runtime environment completely for the execution of any mobile agent.
two, the life cycle of mobile agent
Mobile agent life cycle in the present invention can be in following any one state (referring to as Fig. 2):
1, initial condition: generate a mobile agent object, but also not upper oneself being registered to AMS, both there is no name, there is no address yet, can not communicate by letter with other mobile agents.
2, active state: mobile agent object registration is upper to AMS, has a formal name and address, has the feature of whole mobile agents.
3, suspension status: current mobile agent object is out of service.Inner thread will be suspended, and not carry out the behavior of mobile agent
4, wait state: mobile agent object is being waited for its corresponding service conditions, will continue operation as long as meet certain condition mobile agent.
5, deletion state: mobile agent has been clearly to have discarded, internal thread has stopped the execution of mobile agent and has deleted from AMS.
6, transfer state: in the time that a mobile agent changes to a reposition, it can enter this state, system can buffer memory those to be sent to the message of reposition.
