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.

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
