【摘要】：運(yùn)營級以太網(wǎng)OAM主要包含故障管理和性能監(jiān)控這兩大基本功能。其中，性能監(jiān)控通常指丟包率、時延/抖動、吞吐量這三項(xiàng)以太網(wǎng)最重要的性能指標(biāo)。傳統(tǒng)以太網(wǎng)性能監(jiān)控測試一般使用儀表對交換機(jī)進(jìn)行離線脫機(jī)測試。 ITU-T Y.1731標(biāo)準(zhǔn)定義了以太網(wǎng)故障管理和性能測試的實(shí)現(xiàn)方法，特別適用于多業(yè)務(wù)等級應(yīng)用為主的城域以太網(wǎng)。但是，ITU-TY.1731的性能監(jiān)控細(xì)分為時延、時延抖動、丟包率等多項(xiàng)功能，同時發(fā)起這些性能測試不僅配置繁瑣，而且性能監(jiān)控作為按需功能無法持續(xù)，如何基于Y.1731標(biāo)準(zhǔn)快速有效監(jiān)控城域以太網(wǎng)性能指標(biāo)成了亟待解決的問題。 本文基于ITU-T Y.1731標(biāo)準(zhǔn)，進(jìn)行實(shí)現(xiàn)城域以太網(wǎng)性能監(jiān)控技術(shù)的有關(guān)研究。首先以ITU-T批準(zhǔn)的Y.1731基于以太網(wǎng)網(wǎng)絡(luò)的OAM功能和機(jī)制為參考，研究性能監(jiān)控測試的原理，包括丟包率、時延/抖動。在協(xié)議研究的過程中，詳細(xì)闡述了相關(guān)技術(shù)的原理和實(shí)現(xiàn)流程。然后具體分析改進(jìn)的以太網(wǎng)性能監(jiān)控方法的主要設(shè)計思路，主要包括該功能模塊的新增功能以及時間校準(zhǔn)方法的流程圖。最后，在烽火網(wǎng)絡(luò)公司USP平臺上搭建實(shí)驗(yàn)環(huán)境，對用該方法測試以太網(wǎng)OAM丟包率、時延/抖動參數(shù)進(jìn)行了驗(yàn)證，并對此進(jìn)行了分析。試驗(yàn)結(jié)果表明，在該方法下，用戶可以設(shè)置最小時間間隔和相關(guān)參數(shù)閾值，并能顯示歷史監(jiān)控情況和實(shí)時監(jiān)控情況,從而達(dá)到更好地監(jiān)控以太網(wǎng)性能參數(shù)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.
