Design And Implementation Of Routing Management In PON System Based On Load Sharing Mode

With the development of Internet access technology and communication technology,and the acceleration of social information,the demand of image,voice and multimedia services is constantly increasing,which also means the sharp growth of network transmission data.4G on mobile devices and 5G technology,which is gradually becoming more and more popular today,pose great challenges to modern networks.In recent years,the rapid development and popularization of passive optical network(PON)has attracted much attention.Compared with traditional access network,PON has advantages of low cost,easy maintenance,strong stability and high reliability.It is also the focus of major communication equipment manufacturers and operators to realize various communication protocols on PON system stably.Link layer protocol in OSI model,link aggregation technology is one of the more widely used technologies.It can not only improve the network transmission rate,but also provide a backup link to protect the role.However,the data processing capacity of single-disk link aggregation is limited compared with cross-disk link aggregation.Therefore,cross-disk link aggregation is born,which can improve the data processing capacity of the system,so as to improve the work efficiency.At the same time,the implementation of routing protocol technology is also very important.It is also an indispensable technology to realize internetwork segment communication on PON system and ensure network speed and stability.Based on IEEE802.3 AD protocol standard and actual project requirements,this paper proposes a PON system routing technology method based on cross-disk link aggregation to achieve the purpose of reducing costs,increasing bandwidth,improving system stability,enhancing data processing capacity,and connecting across network segment.In this paper,the PON system network structure,implementation principle,LACP protocol and three-layer routing protocol are described in detail.Secondly,the paper introduces the detailed design scheme and implementation method of this subject.Finally,it is supported by experiments on Huawei e NSP simulator and OLT developed in this project.The experimental results show that the implementation of routing technology based on the cross-disk link aggregation technology meets the functional requirements of the project development,which not only improves the link bandwidth and realizes the cross-network segment connection,but also enhances the stability and reliability of the system.
