Design And Implementation Of Network Element Software System Of Optical Transmission Equipment Based On SNMP

In recent years,with the rapid development of information and technology,optical transmission technology has gradually developed into the research focus of national communication network.Various communication devices have sprung up,and there are some research results in the field,which can deal with device communication and abnormal results.It is widely used in banking,education,military,medical and other fields.With the expansion of the application field of optical transmission equipment and the higher and higher requirements for the communication quality of equipment,the current network element software system of optical transmission equipment still has deficiencies in reliable data transmission,master control line card management,problem real-time positioning and so on.Firstly,there are many communication modes of equipment hardware at present.Most of the communication modes do not carry out data verification,and there is a problem of unreliable data in transmission.Then,when the current master manages multiple line cards,the transmission efficiency is too low to ensure the real-time performance of data transmission rate.Finally,when the optical transmission equipment is put into the specific field application,there are complex field environments such as long distance from the station,inconvenient traffic,prohibition of personnel from entering at will and so on.Lack of positioning problem analysis function.To solve the above problems,this paper proposes a network element software system based on optical transmission equipment.Firstly,the data transmission of the communication interface of the main control card is optimized.The data transmission between the main control card and each line card uses the user datagram protocol(UDP)synchronization mechanism: UDP synchronization mechanism improves the reliable transmission of data,and can greatly save the resources occupied by the central processing unit(CPU)compared with the transmission control protocol(TCP).The master adopts the Dynamic Host Configuration Protocol(DHCP)technology to optimize the address allocation of the line card through the MAC address of the line card,which facilitates the master's management of the line card.By registering the channel management interface,the operation efficiency of the board is improved.Finally,according to the actual application scenario of the equipment,the functions of alarm supervision,optical power performance monitoring statistics and automatic optical power reduction(APR)are proposed,and the second level processing process of alarm reporting and performance monitoring is carried out to solve the problem of difficult on-site positioning.Analyze the data and locate the problem.In addition,this paper independently designs the private management information(MIB)library,which can read,modify and monitor MIB data safely and effectively in the MIB Browser,which improves the effective management of equipment.The experimental results show that the network element software system is not only reliable in the management of line card and data transmission,but also has high resource utilization,and improves the communication efficiency between main control and line card.Through the data transformation of Secure CRT terminal and private MIB file,it can accurately locate the on-site problem analysis and improve the efficiency of problem solving.
