Research Of Distributed Network Management Model Based On Mobile Agent And Agents Group

With the continous development of application and technology of computer network,the computer network has become more and more popular in our common life.The development make everyone's daily life even the life line of one country depend on the computer network heavily,so stability and reliability of network runing are seemed to be vital,and thus network management emerges as the times requires.Network management technology has been developing rapidly since SNMP (Simple Network Management Protocol) was published at the end of 1980s.lt becomes an essential element in constructing and maintaining networks along with the enhancement of management functions and expanding of managed objects.The current commercial network management softwares are all based on SNMP frame.The management agent daemoning in the managed device is responsible for maintaining the MIB of the device.The management station is responsible for manipulating all the data.The model has exposured some disadvantages,for example that the management agent has no intelligence and is short of flexibility.Though the layer frame of SNMPv2 protocol overcomes the disadvantages of concentrative management in some extent.But the ability of communication between manager and manager is limited.and the management function is yet short of flexibility and intelligence and the problem can't be resolved in nature.The emergence of mobile agent gives network management an revolution,and soon the mobile agent becomes the hotspot of research.Mobile agent is the intelligence body that can move in the network and complete relevant tasks,it has the feature of mobility,intelligence, concurrent,autonomy,durative.The advantages of mobile agent primely make up for the lack of network management system based on SNMP protocol and meet the variety requirement of the network development.With the expanding of network, network management is from concentration to distribution gradually.At the same time,the SNMP protocol is being seemed as mainstream network management protocol and supported by most of the devices in present network.So the distributed network management based on SNMP protocol and mobile agent is becoming the hotspot of current research.This paper aims at the research of the model of network management based on SNMP protocol and mobile agent and agents group.The emphaseses of the research are on the SNMP protocol,mobile agent,agents group and the distributed network management model which combines SNMP protocol,mobile agent.agents group.
