Research On Internet Broadband Access Technology And Its Engineering Implementation

As a subject of combination of computer science and communication technology,broadband access network is the key point to the development of national information infrastructure.In recent years,with the rapid evolution of Internet and communication network technology,the demand for network quality is gradually increasing,and the rise of cloud computing and big data services has also brought new requirements for network services.Meanwhile,the broadband access network is still one of the bottlenecks in the development of communication networks.Choosing appropriate access network technology to construct and deploy broadband access network efficiently is the key to solve the problems facing today.This thesis focuses on the practical research of Internet broadband access technology.The main work of this thesis includes:(1)Summarize the overall development of broadband access network technology,analyze the necessity of rational use of access network technology in engineering practice,outline the broadband access technology architecture,carry out detailed analysis and research on key technologies of broadband access network,and various broadband access technologies are compared in terms of transmission efficiency,transmission mode,deployment cost and construction environment.(2)Typical schemes and deployment principle of FTTH technology are analyzed,and FTTH access mode is analyzed from network structure.The functions and deployment strategies of OLT,ONU and ODN are elaborated,and the scenarios that FTTH is applicable to are provided.Through the modeling of different application scenarios,several construction schemes of FTTH access technology based on GPON are proposed.(3)Based on the FTTH access technology of GPON,the broadband access schemes of two campuses of Huaiyin Normal University are designed and implemented according to the user's application requirements,including the design of network topology structure,the deployment of access layer OLT,BRAS equipment,network management system,dual hot standby and light cat.The feasibility of construction,construction method and test results of construction acceptance are expounded in detail.
