6. the future work

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

Intelligent Agent

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 envi

A mobile agent System

• 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.

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.

Environment

• 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 i
