| With the development of the society, people's needs for communication are increasing, and demands for communication quality are also more and more high. The demands for communication gradually transfer to type diversification and unsure flow direction, which bring forward more strict requests to transmission equipment for optical transmission network of the next generation. However, the traditional SDH and WDM network can't satisfy the needs of fast expand of correspondence demands, whose bandwidth is dynamically alterable. Therefore, with the background of mutual restriction between new operation demands and existing network frame, the idea of ASON is born.This dissertation firstly introduces the technology principle and specialty of ASON skills from system frame, criterion evolvement as well as equipment development. Also, the situation of ASON equipment research is presented by compares among different manufacturers. Then the application examples of ASON in or abroad are listed in detail, which ensures the bright future of ASON.Network layout is the key factor and important guarantee of the ASON realization and network intelligence. On the basis of introduction for evolvement of ASON network construction, this dissertation emphasizes the principles, process and approach of network layout and design, and takes OptiX MDS 6600 for example to introduce the function and operation procedures of layout software. Next, construction scheme of Guangxi Mobile ASON optical network is accordingly analyzed in detail from network actuality, operation demands and construction principles, which lively demonstrates working process of network design. Finally, some noticeable problems and tips about the practical network design and the import of ASON skills are proposed, playing an important role of application.The work done by this dissertation possesses a positive meaning in ASON research fields, and should act as a good reference for superficial application of ASON skills in the future. |
