5. What’s Intelligent Agent? [Wooldridge and Jennings 1995] Autonomous: agents perform majority of their tasks without the direct intervention of humans or other agents. Social ability: agents interact, when they deem order to accomplish their tasks and to help others. Responsiveness: agents perceive their environment and respond in a timely fashion to changes occurring in the environment.

13. Advantages of Using Mobile Agent Cut down network load (makes the connection quality better). Mobile Agents and Network Load Reduction (Danny B. Lange, 1998)

14. Advantages of Using Mobile Agent (cont.) They overcome network latency They execute asynchronously and autonomously. Mobile Agent has capability of adapting and reacting network environment changes dynamically and automatically.

15. Fault-tolerant. When a host where Agent is running tends to crash, all Agents will be warned and given time to dispatch and continue their tasks on another host in the network. Scalability. Another benefit of using Agent system is easy to add new Agents to an existed Agent host. Advantages of Using Mobile Agent (cont.)

19. NameRoles UserWhen making a tracking request via a portal web-site, users provide Order-No or Customer-No to User Interface. User Interface User Interface receives users ’ information and passes it Coordinators. Coordinators AgentCoordinator Agent gets information from user through User Interface, and then performs routing, that is, figuring the company holding the user ’ s order. Information GrabberAfter routing, Coordinator Agent passes the information got from user to Information Grabber. Then Information Grabber grabs related data from external source either via mid-tier programs or by itself. External ResourcesExternal Resource is where the needed data externally stored.

23. System Structure Order-Tracing Agent

24. 1. Send Customer ID or Order ID to retailer’s website. Retailer means who the customer placed order to. Any type of Web-Server can be used for receiving users’ Order-Tracing request entrance only if it is connected to Agent-Center. 2. Pass ID to Agent-Center. Alliances’ web-servers must have two main features to work with Agent- Center. One is the parameters that will be received by Agent-Center; two is the ‘action’ got to be pointed to the Agent-Center’s address. 3. In the Agent-Center, here is a critical component called Agent-Web-Server, which is full time standby for receiving ID messages that customers passed to retailer’s Web-Server. Agent-Web- Server acts as the main role in the Order-Tracing system. In this step, when retailer’s web-server receives customers ID messages, it will be automatically passed to Agent-Web-Server, and a sequence of activities will be invoked by the Agent- Web-Sever. System Procedure(1) Order-Tracing Agent Retailer

25. 4 AgentCenterHub Agent is invoked to decide which alliance it should dispatch to. The searching mechanism is designed and programmed here. By retrieving the IP address stored in the AgentCenter’s database, Agents have specific destinations to go and ask for certain services. 5. After AgentCenterHub has destination data in hand, Coordinators are invoked to be dispatched to those destinations and are given the customer’s ID data. 6. Coordinators invoke Information Grabbers in Alliances’ hosts and pass the ID to it. Order-Tracing Agent System Procedure(2)

26. 7. The Information Grabber invoked by the Coordinator then starts to retrieve the local database and set about its order existence check procedure according to the customer’s ID. 8. If this specific order is confirmed to be existed in certain firm, the Information Grabber then replies ‘Affirmative’ to the Coordinator. The Coordinator then goes back and reports it to the AgentWebServer Agent to have the Presenter ready to present the order information. Order-Tracing Agent System Procedure(3)

32. System Installation Agent platform installation: 1. Directly copy the Aglet1.1_ from the source CD to the destination directory. 2. Set up the environment variable: CLASSPATH: Agent variable:.;C:\aglets1.1.0\lib;C:\aglets1.1.0\public; For connecting Oracle database: o:\oracle\ora81\jdbc\lib\classes12.zip; For connecting SQL database: C:\driver\freetds_jdbc\freetds_jdbc.jar Add aglet_home variable and set it for your aglet directory Add jdk_home variable and set it for your jdk directory PATH: C:\aglet1.1_\aglets1.1.0\bin; Note that the C: or o: directory is depending on where you installed it for. System Installation Dealer side: copy the files from the CD’s directory “system/dealer_side” to your system’s (aglethome, usually named Aglet1.1_)/ aglets1.1.0/ public/ thesis. Data side: copy the files from the CD’s directory “system/data_side” to your system’s (aglethome, usually named Aglet1.1_)/ aglets1.1.0/ public/ thesis. Note: customize the “InfoGrabber.java” file for connecting the database. And then recompile this modified file and reboot the Aglet system.
