Research On The Optimizing Scheme Of Tietong's GPON Network Uplink Bearer

Today,major operators are struggling to expand their market coverage.From the early 2G communications to the later 4G smart communications,the three major operators in China are expanding their business territory to the extreme.Until recent years,major operators have demonstrated their magic in the home broadband market,hoping to dominate the future home broadband market.A mobile company in a certain city has secretly worked hard to form a fraternal unit with the local Tietong company,complete the construction of the provincial network direct link,achieve mutual business visits,and jointly expand the territory in a home broadband market in a city,and strive to Win an unbeatable reputation in the customer base.The Tietong company used the advantages of GPON technology's high speed,low cost,and wide coverage to use the GPON network earlier to cover the local home broadband market resources.However,with the explosive growth of home broadband demand,the position of OLT equipment in the network It is also getting higher and higher.Networking forms such as FTTH,FTTB and FTTO put forward requirements for higher reliability and faster traffic for GPON networking applications.Network bandwidth capacity and security are also challenged.The current online bandwidth is insufficient,and Tietong City The pressure of the local area network is huge,and the uplink of the bare fiber single fiber also exposes the weakness of network security.The Tietong company needed an effective measure to quickly and stably solve the current network problems.This article mainly studies the technology and characteristics of the GPON network based on the consideration of available network resource conditions such as a transmission network and a metropolitan area network.How to quickly and cost-effectively solve the existing network problems and how to optimize GPON in the long run The network is well placed to do a good job.Through a detailed survey of mobile and Tietong resources in a certain city,it is considered that in the short term,it is difficult to solve the existing problems related to the capacity and security of the Tietong GPON network by constructing the Tietong metropolitan area network and transmission network.After investigating the mobile network resources in a certain city,this paper advocates the bold use of the "two-network integration" method,which is the best solution for the optimization and rectification of Tietong's GPON network.A city's transmission network and metropolitan area network is large in scale,rich in resources,and regularly maintains data and regulates traffic.It will “graft” Tietong OLT into the mobile metropolitan area network,and take mobile OTN transmission protection,and finally point to the mobile Internet exit,which can greatly solve the problem.When network traffic congestion bottlenecks and upstream transmission security issues.During the transformation,this article compared several OLT uplink data protection methods,studied the basic principles of LACP,UAPA,and VRRP protocols,and determined the OLT uplink data protection scheme according to the needs of this transformation.Several connection modes of MAN and OLT are listed,and the feasibility in the existing network is analyzed one by one.The type of the uplink transmission channel is determined.After comparing the advantages and disadvantages of the horizontal and vertical directions,the final channel type is determined.Visited equipment manufacturers of metropolitan area networks to understand the future network equipment network distribution trends and included them in subsequent optimization plans.This paper analyzes the structure and design of user data under the OLT in the existing network,organizes the cutover data,and finally formulates a final optimization and transformation plan for a city's Tietong GPON network,and uses a certain city's Tietong and OLT as a pilot project to carry out actual optimization Reconstruction work.By comparing the data of the provincial mobile traffic monitoring platform before and after,it can be seen that the optimization measures studied in this paper are effective,greatly reducing the cost and cycle of the reconstruction.At the same time,the network traffic congestion problem and the security brought by the original OLT bare fiber single uplink The problems were resolved.
