Research On The Management Of Network Based On Mobile Agent

At present,the scale and complexity of computer networks have been expanding,the demands of heterogeneous,flexible and expansively are more and more urgent.In this case, tradition SNMP network management appeals its weak point,it's based on Manager/Agent Model.This centralized management has little flexibility and intelligent,it's easily to cause traffic bottleneck,and hard to fit the development of network,this needs a new management and architecture.The mobile Agent technology gives a revolution to network management.It has the characters of mobility,intelligence,parallelism,autonomy,and continuity.Besides,its high intelligence and powerful remote data process ability,can remarkable reduce the load of network traffic and management station.Parallelism can balance the traffic,optimize network performance.It can runs on many platforms,and use to manage huge,distributed, heterogeneous network.It also can be customized,give a flex way to manage.The mobile Agent technology will cover the shortage of SNMP based managements,obviously add up the flexibility and expansibility,minimize the traffic delay and load,and greatly improve the performance of network management system.This thesis presents a hybrid environment where network management application uses mobile agents to interact with SNMP agent via SNMP Protoeol.The Prototype implementation is also discussed in IBMAglet.By designing an Data Collection Agent which is used to collect the information of system,this thesis shows how mobile agent works in performance managemen.Some important technology of system is also analyzed detailedly and implemented in Aglet.Meanwhile,the development method of Objeet一Oriented and design patteirn technology are successfully used to develop the function modules of system so that the architecture of system is very flexible and scalable.These models provide a reference and practical values to apply and research of the management systems based on mobile agent technology.
