【摘要】：运营级以太网OAM主要包含故障管理和性能监控这两大基本功能。其中，性能监控通常指丢包率、时延/抖动、吞吐量这三项以太网最重要的性能指标。传统以太网性能监控测试一般使用仪表对交换机进行离线脱机测试。 ITU-T Y.1731标准定义了以太网故障管理和性能测试的实现方法，特别适用于多业务等级应用为主的城域以太网。但是，ITU-TY.1731的性能监控细分为时延、时延抖动、丢包率等多项功能，同时发起这些性能测试不仅配置繁琐，而且性能监控作为按需功能无法持续，如何基于Y.1731标准快速有效监控城域以太网性能指标成了亟待解决的问题。本文基于ITU-T Y.1731标准，进行实现城域以太网性能监控技术的有关研究。首先以ITU-T批准的Y.1731基于以太网网络的OAM功能和机制为参考，研究性能监控测试的原理，包括丢包率、时延/抖动。在协议研究的过程中，详细阐述了相关技术的原理和实现流程。然后具体分析改进的以太网性能监控方法的主要设计思路，主要包括该功能模块的新增功能以及时间校准方法的流程图。最后，在烽火网络公司USP平台上搭建实验环境，对用该方法测试以太网OAM丢包率、时延/抖动参数进行了验证，并对此进行了分析。试验结果表明，在该方法下，用户可以设置最小时间间隔和相关参数阈值，并能显示历史监控情况和实时监控情况,从而达到更好地监控以太网性能参数的目的。
[Abstract]:Operational Ethernet OAM mainly includes two basic functions: fault management and performance monitoring. Performance monitoring usually refers to packet loss rate, delay / jitter, throughput, which are the three most important performance indicators of Ethernet. The traditional Ethernet performance monitoring test generally uses the instrument to carry on off-line offline test to the switch. The ITU-T Y.1731 standard defines the implementation method of Ethernet fault management and performance testing, especially for metropolitan Ethernet with multi-service level applications. However, the performance monitoring of ITU-TY.1731 can be subdivided into several functions, such as delay, delay jitter, packet loss rate, etc. How to quickly and effectively monitor the performance index of Metro Ethernet based on Y. 1731 has become an urgent problem. Based on ITU-T Y. 1731 standard, this paper studies the performance monitoring technology of Metro Ethernet. Firstly, based on the OAM function and mechanism of Ethernet network approved by ITU-T, the principle of performance monitoring and testing, including packet loss rate, delay / jitter, is studied. In the process of protocol research, the principle and implementation flow of related technology are described in detail. Then the main design ideas of the improved Ethernet performance monitoring method are analyzed, including the new function of the function module and the flow chart of the time calibration method. Finally, the experimental environment is built on the USP platform of the beacon network company, and the test method is used to test the packet loss rate, delay / jitter parameters of Ethernet OAM, and the analysis of this method is carried out. The experimental results show that under this method, the user can set the minimum time interval and the threshold of related parameters, and can display the historical monitoring and real-time monitoring, so that the Ethernet performance parameters can be monitored better.
