Research And Design Of End-to-End Quality Assurance For JiangXi Telecom Optical Network

The core of "Broadband China" strategy lies in improving the user's household bandwidth and realizing the real "broadband".After several years of exploration,China Telecom has made a great breakthrough in the coverage of optical fiber network.PON network has gradually replaced copper cable network and become a new generation of access network for China Telecom.FTTH is one of PON network's main access methods.Quality assurance of these users is a new topic of our research.Thesis aims to study the PON network management interconnection scheme of JiangXi telecom access network,and introduce the principle of PON network management.Based on resource information,comprehensive analysis and comprehensive judgment,Thesis has realized automatic obstacle determination and intelligent analysis of FTTH user quality of JiangXi telecom,and has constructed an End-to-End system of JiangXi telecom optical network.Thesis mainly studies the three-layer VPN interconnection of access network,designs PON network management to collect the key indicators of OLT/ONU,and links all kinds of resource information.It also designs and sorts lots of rules to realize the automatic obstacle determination function of FTTH user quality by studying the network factors affecting user perception.We have researched and designed the End-to-End quality system of the user dimension.Through big data analysis,the system has realized the pre-inspection and repaired of the user dimension and the early warning of business quality.Thesis innovatively designs the implementation scheme of interconnection between the access network and the provincial center of all cities in the province,and makes preparations for PON comprehensive network management cloud;Thesis realizes the automatic obstacle determination function of optical network users by collecting all kinds of data affecting users' perception designing and sorting out rules;Thesis studies all kinds of algorithms through big data analysis.The intelligent analysis of the quality of optical network users is realized.JiangXi telecom optical network end-to-end system has effectively supported the construction and maintenance.
