Data Consistency Strategy In PTN Network Management System

With people's continuous demands expansion of communication network,new communications network PTN is becoming more popular,at the same time,the development and optimization of PTN network management system has also become the focus of society communication research.To make PTN network management system more efficient,it is necessary to Solve some problems when it runs,among which data consistency is one of the key problem.Data inconsistency will not only affect the user's control on the communication network,which reduces people's trust in the network management system,but also may lead to serious consequences such as block or crash.Therefore it's urgent to improve the data consistency stragedy in PTN network management system.Based on the research of PTN network-related technology,the thesis analyzes the thesis analyzes data consistency issues in PTN network management system,and develops appropriate strategies to solve the problem for every category.The primary work is as follows:(1)Based on the analysis of the system development framework of PTN network management system,the various business segments and processes,the thesis studies the primary data inconsistency the thesis studies in the current system.The data consistency issues are distinguished into three categories: data consistency between EMS and network management system,between the Network Management System and NEs,and between the various businesses.The thesis studies the cause of each type of consistency.(2)For three types of data consistency issues occurred in PTN network management system,the thesis studies the solving strategies and key technologies.Data consistency problem between EMS and network management system is solved by synchronization algorithm based on the transaction log merging;data consistency between network element and NE is sovled by subscription and distribution mechanism and NE processing strategy of chain scission.Data consistency problems between business data is solved by data consistency check and automatic recovery technology.(3)The thesis designs the solution strategies and core technologies of the above data consistency problems and deploys network management system in Windows systems.The thesis does functional test on the synchronization process,the building of subscription relationship,comparison of business data consistency and automatic recovery module.Current research on solution of PTN network management system data consistency problem is still in the initial stage,there is no unified standard solution.This thesis studies and implements strategy to ensure data consistency in PTN network management system,which has a certain engineering significance in relevant fields.
