Research On Concurrent Data Analysis Technology Of Network Node

With the popularity of computer application technology and the rapid development of virtualization technology,the network of carry business information has penetrated into all fields of people's life.A network often by a larger number of function nodes(network equipment or terminal)connected component.How to effectively and timely found all nodes in the network,how to real-timely monitor the variation status and abnormal events,how to dynamically calculate the network topology,how to identify topology under cloud architecture,which becomes the main problem of reliable operation of network autonomous domain system.Starting from the traditional network node monitoring technology,this paper made in-depth analysis of the network node data mutation detection technology and the network technology computing technology,cleared the objective requirement of the new generation of network monitoring system,including of discovering complex network topology dynamically,node data variation real-time monitoring and identify topology under cloud architecture.Research and improve the network node concurrent data analysis technology.Research based on SNMP protocol and BFD protocol focused on the key technologies of data monitoring network node structure,including the type of node id uniquely identifies and discern,puts forward the virtual and hidden nodes detection technology,puts forward the technique of network topology discovery based on three table,puts forward the link layer hidden node topology computing technology,puts forward the technique of network topology is proposed based on BFD protocol,improve the mechanism of the alarm information collection and reporting.All modules were designed on the principle of achieving functions and optimizing performance,the research can achieve monitor in real time of network node running status and report exception,preliminary identification of node topology in cloud architecture,help managers timely find abnormalities and effectively solve problems.Based on the above works and around the compatibility,robustness and high efficiency of the system,the functionality and performance of system has tested in the real network environment.The test results show that the system can real-time grasp the running state of the network nodes and abnormal events,plays an important role for the safe operation of the network system.
