| The bandwidth and traffic of high-speed optical fiber backbone network is growing rapidly,which means the signal accessing and processing of the backbone network is becoming the basis of information security,network management and behavior analysis and other related technologies.It is significant for our military to practice the cyberspace attack-defense war that switching access and preprocessing the optical transport network(OTN)signals at 100 Gbps rate level with high-performance,which laying a solid foundation for the "Big Data" era that has come.Facing the rapid development of cyberspace field and strategic situation of our country and military,this paper regarded the 100 Gbps OTN signal as object of study,proposed and designed 100 Gbps OTN signal access and processing system.The main work is as follows:(1)Analyzed the mainstream optical network transmission technology and OTN receiving and processing equipment,and summarizes the main procedures and technologies that are currently applied to 100 Gbps OTN signal access and processing;(2)According to the mission requirements,the overall design scheme of 100 Gbps OTN signal access and processing system is put forward.Through the analysis and demonstration,the paper puts forward the concrete realization method of the main function module of the system;(3)Designed,manufactured and debuged 100 Gbps OTN signal full speed access and error correction decoding processing of the hardware circuit board,completed the hardware base of the total system;(4)By utilizing RS(255,239)encoding,finished the signal forward error correction,completed the goal of signal access processing;(5)Deeply analysied of the 100 Gbps OTN signal access processing technology in all aspects,summarized and testedentire system performance. |
