The Design And Analysis Of Triple-play Terminal Software System Based On PON Network

NPC(the National People's Congress)and CPPCC(Chinese People's Political Consultative Conference)are going to be held soon this year.Premier Li Keqiang's government work report in 2018 viewed the Internet as the green power of the new economy,with reference to the Internet-related policies.Tri-network integration refers to the information and communication network where the three major networks of telecommunication network,computer network and cable television network are mutually infiltrated and compatible,and integrated into one,providing comprehensive multimedia communication services including voice,data,and images.The triple play network provides a high-speed broadband multimedia platform for the realization of the Internet.To promote high-bandwidth access services requires high-speed metropolitan bearer networks and access terminals that provide multiple services to home users.The access terminal is located in the user's home.In the entire metropolitan area network,the device most closely contacted by the customer,its function and performance deeply affect the customer's perception of the entire network.This topic is designed based on the PON network three-network convergence terminal software system for discussion and research,home gateway terminal design and functional performance test analysis,in the home gateway terminal to improve the user's perception of the network.This topic mainly did the following work:(1)According to the International Telecommunication Development Alliance and international regulatory standards,introduced the relevant technologies of triple play,briefly described the development and current status of PON networks,elaborated the technical principles of 10G GPON,and compared them with the existing GPON.The technical SIP protocol of VOIP is introduced.Finally,the technical principles and functions of IPTV are introduced.(2)Begin to elaborate the problems faced by the triple play software system,start from the problems,put forward the main points of requirement analysis,analyze the functional requirements and performance requirements of the three service modules of the triple play system,and specify the goals for test analysis..(3)It is clear that the home gateway terminal of this project is based on BCM chip design,and the software system is to build a platform in the embedded Linux environment.Then the architecture of the software system is introduced,and the overall functional modules are designed in layers.Then the functional design and performance design of the three modules of WAN,VOIP and IPTV are respectively described.(4)Finally simulate the operator's network to set up a corresponding test environment,test and analyze the function and performance of the three main service modules of the home gateway terminal,and finally test the integration of the three major services in one,and put forward a variety of pressure and load,etc.Performance Testing.The terminal equipment studied in this paper has already been initially developed and gradually put into mass production.In the operator's PON network,downlink bandwidth of up to 200Mbps or more can be provided.In addition,the design of the software system used in this project has a certain degree of portability and extensibility in the home gateway terminal of DSL,CABLE,etc.,and the test and analysis method plan has certain reference.
