【摘要】：随着互联网技术的广泛应用,各种业务的发展方向是IP化。为了实现宽带IP业务灵活调度,提供灵活的网络保护和恢复机制,传输网不仅要提供高容量带宽,以满足宽带业务需求,更需要提供功能良好的端到端网络运行与操作管理(OAM)能力。OTN设备结合了SDH与WDM的优势,OTN有强大的OAM功能,可以实现大颗粒业务的灵活调度和保护,解决了SDH设备处理大颗粒业务效率低下的问题,OTN也可以提供超大容量的带宽传送。未来,OTN设备会引入更高的速率接口,目前100G OTN以及商用部署,中国移动已经在进行400G OTN设备测试。关于400G标准还没有成熟,存在多种技术选择,预计不久的将来会实现标准化。 随着OTN设备的大规模部署,OTN网络与其他网络的联合组网越来越重要。OTN与现有SDH/WDM网络联合组网,OTN与路由器IP承载网络联合组网以及多厂家互联互通成为研究的重点。OTN与SDH、IP路由器网络联合组网可以更好的优化组网结构,提高网络带宽利用率。本文的主要研究内容及成果如下： 研究不同厂家OTN设备与SDH设备业务互联互通主要问题及关键技术,根据业务互联互通存在的问题构建测试实验环境,对测试数据进行分析,提出业务互联互通解决方案。根据铁路骨干光传送网平滑升级改造实际需求,提出OTN与SDH三种组网架构,并构建实验环境进行测试验证,对测试数据进行分析比较,针对不同网络平滑升级改造环境给出相应的解决方案。对目前铁路时钟时间同步网存在的问题及缺陷进行分析研究,并对同一厂家及不同厂家OTN与SDH设备1588V2时钟组网方案进行研究,分别给出相应的1588V2组网解决方案。 对不同厂家OTN与路由器业务互联互通主要问题进行研究,并构建对应的实验环境进行测试验证,提出业务互联互通解决方案。在OTN与路由器保护协调技术及联合组网中,针对OTN与路由器端到端OAM开销协调处理以及OTN与路由器保护协调的问题,构建相应测试环境,对测试数据进行分析研究,给出了保护协调的解决方案。
[Abstract]:With the wide application of Internet technology, the development direction of various services is IP. In order to achieve flexible scheduling of broadband IP services and provide flexible network protection and recovery mechanism, transmission networks should not only provide high capacity bandwidth to meet the requirements of broadband services. It is also necessary to provide a well-functioning end-to-end network operation and operation management (OAM) capability. OTN equipment combines the advantages of SDH and WDM. OTN has a powerful OAM function and can achieve flexible scheduling and protection of large granular services. It solves the problem that SDH equipment is inefficient in dealing with large particle traffic. OTN can also provide very large capacity bandwidth transmission. In the future, the OTN device will introduce a higher rate interface, currently 100G OTN and commercial deployment, and China Mobile is already testing 400G OTN devices. The 400 G standard is not yet mature, there are a variety of technical options, is expected to be standardized in the near future. With the large-scale deployment of OTN equipment, it is becoming more and more important to combine OTN network with other networks. OTN and existing SDH/WDM network, OTN and router IP bearer network, as well as multi-vendor interconnection become the focus of research. OTN and SDHN IP router network can better optimize the network structure. Improve the utilization of network bandwidth. The main contents and achievements of this paper are as follows: the main problems and key technologies of business interconnection between OTN equipment and SDH equipment from different manufacturers are studied, and the test environment is constructed according to the problems existing in service interconnection. The test data are analyzed and the solution of service interconnection is put forward. According to the actual requirement of smooth upgrading and upgrading of railway backbone optical transport network, three kinds of network architecture, OTN and SDH, are put forward, and the experimental environment is built to test and verify, and the test data are analyzed and compared. According to different network smooth upgrade environment, the corresponding solution is given. The problems and defects of railway clock time synchronization network are analyzed and studied.
