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
1. A survey of Network Management – 1990 s: 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
the paradigms of network management
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
• The standards for agent – KQML(Knowledge Query Manipulation Language) – OMG’s MASIF (Mobile Agent System Interoperability Facility ) – FIPA (the Foundation for Intelligent Physical Agents)
• 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).
• Mobile Agent – comes from the distributed application community – a software agent that can roam between execution environments
• The current research of mobile agent – Aglets(IBM), AMETES(Goethe Universität), D’Agent (Dartmouth College), Grasshopper(IKV++Gmh. H), …etc. More projects are listed in Appendix A.
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
4. The architecure of IMA system – Manager Agent: the manager of agents. – Action Agent (AA): the work agent under the control of manager agent.
4. The architecure of IMA system
• Research in the 5 areas of Network Management – Performance management – Configuration management – Accounting management – Fault management – Security management
The benefit from Intelligent Agent and Mobile Agent: • Data remote collection • Real-time monitor • Remote control and operation • Data intelligent analysis • Multi-agent collaboration
• 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
