The Research And Implement Of The IP Network Data Collecting Mechanism Based On The Dynamic Task Agent

Along with the increasing scale and complicacy of the network, and various of devices and interface technologies, it's harder to manage the network effectively and keep the running quality of the network .It's the base of the IP network management to get the IP network management data reliably and timely through effective collecting methods. So, the research of data collection which is highly timely and strongly expansible is always an important problem in the network management area.As for the problems in the existing collecting methods, this paper puts forward the data collecting way based on the dynamic task agent, and gives out the structure of this method to make it accord with the demands of flexible collecting, abroad collecting content, and provide varies of collecting strategies, also this paper does some research on some key problems and gives us the solutions to them.1) Abstract collecting strategy: abstract a serial of commands which are for performance data-acquisition to a collecting strategy.2) The adapting of the collecting strategy: abstract the corresponding process from a collecting task to a collecting strategy to an adapting regular, and save it in the configuration files, this way divides the operation logic and the process.3) The way of transformation and link: we use the way of linking terminal to link to the destination device as a whole, and then execute the collecting strategy. We find two linking ways which can fulfill the demands: Telnet and SSH ways, the first way uses the proclaimed in writing way for network data transformation, it has hidden trouble in the security of network data. The second way uses encrypted data transformation, it figures out the security problem of network data transformation.4) Collecting result parsing: as for the collecting result parsing, we use the way used in problem 2. We define different parsing regulars for different returned files which belong to different device types, different manufactures, and different operation systems, the parsing regulars are described by regular expressions.On the base of the research and the solution given of the key problems listed above, this paper gives out the Java implement of the dynamic task agent data collecting method, and has successfully applied this implement in a large IP network integrated management platform project, and obtains favorable impacts.
