【摘要】：在数字化网络日益增长和普及的当今,各种类型的数字信号共享网络。随着数字信号颗粒呈现高速率、高带宽的发展,作为一切信号承载网的城域网也需朝着更加稳定、更加高速、更加灵活、更加安全的方向发展,而基于OTN技术的城域网正能很好的解决这一问题。本文首先对城域网建设、OTN技术应用于城域网、模拟测试平台搭建进行了详细的需求分析,明确了城域网的重要性和OTN技术应用的必要性,且需要一个模拟的测试平台对各种网络应用进行测试和分析,得出结论和方法。再对OTN技术中涉及到城域网组网的部分进行了详细的分析,包括OTN城域网的层次结构、帧结构、开销信息、封装方法等,为OTN城域网设计建设中的技术采用和实施提供支持。然后探讨了新型城域网应该具备的特征,包括网络安全、网络承载方式、多业务传送、网络性能等,为OTN城域网的运营提供评判手段和方式。进而对城域网中传送的各种重要业务进行分析和讨论,包括业务的接入方式、业务的传送特征等,体现出OTN城域网中多业务接入和运行的优势。再对OTN城域网的专用管理仿真软件进行了设计和开发,得到了专用的成都OTN城域网仿真管理软件,该软件包含了OTN城域网各项功能实现的各种基础模块。在基于以上讨论分析的基础上,搭建了基于OTN技术的模拟城域网,包括网络设备和网管的选择、网络规划、设备特征、波道规划等,模拟建设了一个小型的、配置基本完整的城域网。再通过在搭建的OTN城域网中,规划和加载不同类型的信号,进而讨论了OTN城域网中的业务配置、保护策略、网络测试等方面的内容,测试和分析了不同类型业务在OTN城域网中的运行情况。通过对以上所有内容的讨论和分析得到了在新一代城域网网络规划建设中,基于OTN技术城域网的巨大优势,得出了基于OTN技术的城域网组网建议方案等,为OTN城域网的规划和建设提供了重要的参考依据。OTN作为一种新型的网络技术,其在城域网建设中的优势十分明显。但是,任何一种新技术的应用必然会有一个摸索前进的过程。本文正是通过对OTN技术多层面的分析、测试、讨论,得出结论和报告,为今后OTN技术的大规模网络应用提供了帮助。
[Abstract]:Nowadays, with the increasing and popularization of digital networks, various types of digital signal sharing networks are available. With the development of digital signal particles with high speed and high bandwidth, man, as a carrier network of all signals, needs to be more stable, faster, more flexible and more secure. The man based on OTN technology can solve this problem very well. In this paper, firstly, the construction of man, the application of OTN technology in metropolitan area network, and the construction of simulation test platform are analyzed in detail, and the importance of man and the necessity of OTN technology application are clarified. A simulated test platform is needed to test and analyze all kinds of network applications and draw conclusions and methods. Then the part of OTN technology related to the construction of metropolitan area network is analyzed in detail, including the hierarchical structure, frame structure, overhead information and encapsulation method of OTN metropolitan area network, which provides support for the technology adoption and implementation in the design and construction of OTN metropolitan area network. Then it discusses the characteristics of the new man, including network security, network carrying mode, multi-service transmission, network performance and so on, which provides the evaluation method and method for the operation of OTN metropolitan area network. Then it analyzes and discusses various important services transmitted in man, including the access mode of services and the characteristics of service transmission, which reflects the advantages of multi-service access and operation in OTN Metropolitan area Network (man). The special management simulation software of OTN metropolitan area network is designed and developed, and a special Chengdu OTN man simulation management software is obtained. The software includes various basic modules for the realization of various functions of OTN metropolitan area network. Based on the above discussion and analysis, an analog man based on OTN technology is built, including the selection of network equipment and network management, network planning, equipment characteristics, channel planning, etc. Basically complete configuration of man. Then through planning and loading different types of signals in the OTN man, the service configuration, protection strategy, network testing and so on in the OTN metropolitan area network are discussed. The operation of different types of services in OTN man is tested and analyzed. Through the discussion and analysis of all the above contents, the great advantages of the man based on OTN technology in the new generation of man network planning and construction are obtained, and the suggestion scheme of the metropolitan area network construction based on OTN technology is obtained. It provides an important reference for the planning and construction of OTN man. As a new type of network technology, OTN has obvious advantages in the construction of metropolitan area network. However, the application of any new technology will inevitably have a process of groping ahead. Through the analysis, test, discussion, conclusion and report of OTN technology, this paper provides the help for the large-scale network application of OTN technology in the future.
