Design And Implementation Of Distributed Network Quality Monitoring System

“Distributed network quality monitoring system”which is a oriented to IP network,intelligent,pure software network quality monitoring products,it can be effectively used in the complex network environment composed of multi vendor network devices.The whole system is based on IP network performance monitoring technology,system development and integration with the actual demand.Network manager through a simulation test center located in the network management center,According to the IP network topology and test requirements deployment test agent and test function,continuous IP network performance monitoring,to do the depth of fault detection in the presence of performance problems,Improve the network operator's working efficiency,shorten the network troubleshooting time.The main research contents of this paper:In view of several important indicators that affect the user's perception of the network,the real-time monitoring and statistics,and then according to the important degree of weight calculation.The results can be used as an indicator to judge the overall quality of a network.in this paper by taking shaanxi branch of China mobile network quality monitoring system as the background.Development and application of requirement analysis for system construction by detailed work process,Uses the object-oriented method to complete the system architecture design.By fully automated process to implement a set of relatively perfect in functions of network quality monitoring information system.The system can be expanded,on-demand dynamic adjustment,real-time testing of distributed network quality monitoring system.To support the network administrator to view and analyze the network quality data from the web management terminal through the terminal commands provided by the web page management terminal in real time.System support through the API interface to achieve from the system management terminal management network traffic.To discuss the processing and analysis of the bottom layer and application layer protocol to realize the classification of the business.This system realize automatic management process,include for quality of network administrators,network maintenance personnel provide test tools such as;Provide test data record;Test node detection;Backup test report;Test report;The network quality evaluation;Test data query;Based on the analysis of statistics;Print quality test report;Rights management functions;Data security;Data management;Each node equipment management;The main functions such as database system.System log records support itself,convenient administrator real-time view.Support reports directly to the output,which can be carried out in accordance with the need of key nodes of network quality assessment,and adjustment suggestion is given.The innovation of this paper is:The performance of the network application layer protocol is analyzed and optimized by the simulation user's real behavior;Through the statistics of large data,on the IP bearer network content,line,equipment,give the optimization of the proposed targeted,at the same time,the traffic on the access layer for early warning.
