Analyse And Adaptation Of Dense Wave-Length Division Multiplexing Network Management Protocol

Dense wave-length division multiplexing (DWDM) can transmit a set of light waves in one fiber. This is a optical technique used to raise the bandwidth on existing fiber backbone networks. Along with the development of optical networks, each equipments manufacturer becomes isolated, which seriously obstructs mutual communication of optical networks equipments. Especially the ambiguity of optical network management protocol can not cause communication of different manufacturers' equipments. Consequently analyzing optical network management protocol is more important in mutually communication of optical networks equipments of many manufactures and many protocols.This paper systemically elaborates the thinking of analyzing DWDM network management protocols. At first, record network management protocol stack data by software of Wireshark grasping the packets, when give orders in networks management end. Then research Optical Supervisory Channel (OSC) capturing data software, including requirements analysis, software design and software test. Catch data on OSC and record total data. Further, analyze the data recorded on OSC, gradually remove the synchronous byte and the official bytes, withdraw the Data Communication Channel (DCC) bytes of network management information and reorganize DCC bytes. Finally under Wireshark of open source environment write a plug-in to analyze network management protocol assumedly. Base on above, put forward the method to verify whether the analyzed protocol is correct or not.Mutual communication of optical networks equipments of many manufacturers in lots of districts is more important, when the capacity of optical networks is bigger and the business loading on it is more. The key of mutual communication is the linking of network management. In addition to draw the uniform management standard, It is this paper's final aim that a kind of DWDM equipment with adaptive function can communicate different manufacturers' equipments.My main work includes:1. Systemically learn the principle, component and function of DWDM equipments. Be familiar with various network management protocols. Design the way of analyzing network management protocol.2. Complete requirements analysis and design of OSC data catching software, test and modify the software. Do experiments to record data using it. Analyze and process a large number of recorded data. Guess the network management protocol daringly.3. Under Wireshark of open source environment develop again for a plug-in to analyze network management protocol assumedly.
