Redundancy Test And Reliability Research Of Information System

At present,the information system has been widely used in all walks of life,which provides convenience for the business,but also for the continuity of the business has brought hidden dangers.Therefore,the reliability of information system directly affects the stability of bearing business,and to guarantee lasting and effective operation of the information system,you need to understand the actual operation of the information system,the operation level reflects the information system through the data information,timely detection of problems in the running process of the system and solve the weakness.Based on the information system of Xijing University is currently running as the background,the first N-1 fault analysis of network equipment,and based on the analysis results of the designed redundancy scheme of Xijing University information system;according to the reliability of information system operation,analyzed from two angles of function and process,using the Petri net theory to establish the reliability model of information system operation process the operation process,information system and quantitative measure of the reliability,through the control on the reliability of information system to safeguard the information system in the operation process;related technology and the redundancy test were studied.The constructed information system redundancy function testing scheme.The specific research contents are as follows:1.Information system N-l automatic fault simulation method and analysis.Xijing University network portal system,OA office system,using the LoadRunner tool to the key links and key nodes in the network topology(server and core switches)fault setting,fault analysis,fault simulation,load action,check check,accident countermeasures form,accident countermeasures form,report output.Aiming at the information portal system and the OA office system,this paper puts forward the scheme of the N-1 fault simulation of the information system,and carries on the simulation experiment.2.Information system redundancy scheme.Analysis of the status quo of Xijing University information system,analysis of single point hazard at present the school of information systems and network equipment;then,according to the school's OA office system,educational management system and school portal,put forward specific design redundancy.3.Reliability evaluation model of information system based on Petri net.Fault analysis is carried out in Xijing University information system as the background,the basic theory of Petri net based financial management system,taking Xijing University as the background,this paper proposed an evaluation model of information system based on Petri network reliability,and the data center platform of financial management system simulation.
