以太OAM连通性检测功能的研究及实现
发布时间：2018-08-01 09:35
【摘要】：以太网诞生之初主要用于局域网。由于局域网本身具有较好的稳定性及可靠性，以太网在设计之初未太过多的考虑管理及维护机制。而随着技术的发展，以太网没有可靠OAM机制的问题不断凸显，制约着以太网在更大范围中的应用。针对于以太网OAM的迫切需求，国际标准化组织IEEE和ITU-T分别制定并公布了802.1ag协议和Y.1731协议。由以上两个协议构成了完整的电信级以太网OAM协议簇。 本文以全球第二大企业级交换机设备商H3C通信公司的Comware V7操作系统中CFD协议功能模块为蓝本进行阐述。CFD协议模块基于IEEE802.1ag和ITU-TY.1731两份协议，主要提供企业级及电信级的基于VLAN的二层链路端到端OAM功能。作者在2012年至2013年于H3C公司实习11个月，完整的参与了CFD模块的开发工作，主要负责其内部以太网告警抑制功能、快速检测功能及性能测试功能的开发工作。本文以模块中最为重要的快速检测及以太网告警抑制为重点进行论述，对其模块架构、业务流程、处理实现进行详细阐述，并在最后进行系统测试来检验模块的功能。作者在项目开发中提出并实现了以太网告警抑制的分布式均衡处理方法，极大的减少了系统实现以太网告警抑制所需要的资源，并且提高了以太网告警抑制处理的速度。 CFD模块实现后，向企业级及电信级网络提供快速且高可靠性的网络连通性监测，补充了以太网在OAM机制的缺失，，从而为以太网在电信级网络的应用提供了保证。
[Abstract]:Ethernet is mainly used in local area network at the beginning of its birth. Because the LAN itself has good stability and reliability, Ethernet has not too much consideration of management and maintenance mechanism at the beginning of the design. With the development of technology, the problem of Ethernet without reliable OAM mechanism is constantly highlighted, and the application of Ethernet in a wider range is made. In the urgent need of Ethernet OAM, the international standardization organization IEEE and ITU-T have formulated and announced the 802.1ag protocol and the Y.1731 protocol respectively. The whole telecom level Ethernet OAM protocol cluster is formed by the above two protocols.
In this paper, the CFD protocol function module in the Comware V7 operating system of H3C communications company H3C communications company, the world's largest enterprise, is described as the blueprint of the CFD protocol function module. The.CFD protocol module is based on the IEEE802.1ag and ITU-TY.1731 protocol based on the two layer link end to end OAM function based on the VLAN based VLAN. The author is from 2012 to 2013. After 11 months of internship in H3C, the company was fully involved in the development of the CFD module, mainly responsible for its internal Ethernet alarm suppression function, rapid detection function and performance testing function development. This paper focuses on the most important rapid detection and Ethernet alarm suppression in the module, and its module architecture and business process. In the project development, the author puts forward and realizes the distributed equilibrium processing method of Ethernet alarm suppression, which greatly reduces the resources needed by the system to realize Ethernet alarm suppression and improves the speed of Ethernet alarm suppression processing. Degree.
After the implementation of the CFD module, it provides fast and reliable network connectivity monitoring to the enterprise and telecommunication networks, complements the lack of Ethernet in the OAM mechanism, thus providing a guarantee for the application of Ethernet in the telecommunication level network.
