1. Distributed Network and System Management Based on Intelligent and Mobile Agents Jianguo Ding 25/03/2002 DVT-DatenVerarbeitungsTechnik FernUniversität

2. Content 1. The survey of network management 2. introduction of agent 3. Network management + intelligent and mobile agent 4. the architecture of the IMA system 5. the 5 areas in network management 6. the future work

3. 1. A survey of Network Management –1990s: SNMP (Simple Network Management Protocol),CMIP (Common Management Information Protocol): centralized –based on CORBA (Common Object Request Broker Architecture): distributed –the paradigms of network management

4. the paradigms of network management

5. 2. Agent: a computational entity that acts on behalf of a user or another program and it is autonomous, both proactive and reactive, and exhibits a certain degree of ability to learn, to cooperate, and to move. –Autonomy –Re-and Pro-activity Reactivity Proactivity –Cooperation –Learning –Mobility

6. The standards for agent –KQML(Knowledge Query Manipulation Language) –OMG’s MASIF (Mobile Agent System Interoperability Facility ) –FIPA (the Foundation for Intelligent Physical Agents)

7. Intelligent Agent –comes from Distributed Artificial Intelligence (DAI) and is spread to distributed system. Intelligent agent usually includes some of the properties described above. –the action of intelligent agent is based on its Beliefs, Desires and Intentions (BDI).

8. Mobile Agent –comes from the distributed application community –a software agent that can roam between execution environments

9. The current research of mobile agent –Aglets(IBM),AMETES(Goethe Universität),D’Agent (Dartmouth College),Grasshopper(IKV++GmhH),…etc. More projects are listed in Appendix A.Appendix A

10. 3.Integrate the Intelligent and Mobile Agent to Network Management Why we select Intelligent and Mobile Agent for network management –Cooperation –Flexibility –Efficiency –Resource saving –Support heterogeneity –Support legacy systems

11. 4. The architecure of IMA system –Manager Agent: the manager of agents. –Action Agent (AA): the work agent under the control of manager agent.

12. 4. The architecure of IMA system

17. Research in the 5 areas of Network Management –Performance management –Configuration management –Accounting management –Fault management –Security management

18. The benefit from Intelligent Agent and Mobile Agent : Data remote collection Real-time monitor Remote control and operation Data intelligent analysis Multi-agent collaboration

19. Future work –integrated architecture of network management based on IA, MA, especially the dynamic architecture to adapt the modification of network topology and structure –the negotiation between Agents (Manager Agent, Action Agent), how to find a efficient and security method to exchange the knowledge and data between agents –the 5 areas in Network management –the security of agents and the security management in Network Management
