Abstract


Intensive optical wavelength division multiplexing (DWDM) optical wavelength can be combined in a group with an optical fiber for transmission. This is a used to improve existing fiber backbone network bandwidth laser technology . With the development of optical networks , each optical network equipment manufacturers dreams , a serious impediment to the optical network equipment interoperability . Especially in the optical network management protocol on the ambiguity , resulting in devices from different manufacturers can not communicate. Therefore resolved optical network management protocol , multi-vendor interoperability in multi-protocol optical networking equipment was of particular importance. This paper describes a more systematic analysis of network management protocol DWDM equipment ideas: First, the NMS orders at the same time with the Wireshark packet capture software , recording the NMS network management protocol stack packet ; then developed optical supervisory channel (OSC) data capture software, including the proposed requirements analysis, software design, software testing and modify the software , the OSC channel data capture , recording all the data ; further analysis of the OSC channel data recorded to gradually exclude the sync bytes and official bytes, extract containing network management information data communication path (DCC) bytes, and recombinant DCC bytes ; finally with Wireshark open source environment , network management protocol simulation analysis writing plugins . On this basis, the proposed network management protocol validation parse out the correct approach. When the optical transmission network capacity increases, carrying business , the more multi-regional multi-vendor interoperability of the greater significance of optical networking equipment . Interoperability is the key to network convergence, in addition to developing a unified management standards, the development of a functional adaptive reuse intensive light (DWDM) equipment , exchange equipment from different vendors is the ultimate goal of this study . My main work includes: 1 , systematic study of the principles of DWDM equipment , composition and function , familiar with common DWDM network protocol stack in a variety of protocols. DWDM network management protocol designed to parse ideas and methods . 2 , complete the optical supervisory channel (OSC) data capture software requirements analysis and design for software testing and modification work , the use of software developed by doing experiments recording data , a lot of analysis and processing of data , guessing network management protocol . 3, in the Wireshark open source environment, write plugins for secondary development, simulation analysis network management protocol .
