网络融合环境下OTN的组网方式

在三网融合形势下,多媒体业务与数据传输需求不断增加,对传统骨干传输网络提出更高的要求。传统的基于WDM、SHD技术的光纤通信网络虽可满足传输容量需求,但存在成本较高、扩展和调度能力差、业务多样化能力弱等问题,不能进行有效的组网,难以满足未来发展的需要,因此选用新一代的OTN技术进行组网成为发展的必然趋势。通过相关资料研究,结合工作实践经验,对OTN技术的特点、OTN在光通信网络中的组网方式进行总结分析,以期促进OTN技术的应用与发展。

On the OTN Network Convergence Networking Environment

Triple play situation,multimedia services and the increasing demand for data transmission,the traditional backbone transmission network put forward higher requirements. Based on traditional WDM,SHD optical fiber communication network technology,although transmission capacity to meet the problem,but there are higher costs,expansion and scheduling ability,business diversification ability is weak and other issues,cannot be effective networking,it is difficult to meet the future development needs,the choice of a new generation of OTN technology for networking has become an inevitable trend. In this paper,information research,combined with practical work experience,OTN technology analyzes the characteristics of its optical communication network networking development is summarized and analyzed in order to promote the application and development of OTN technology.
