【摘要】：當(dāng)今社會,隨著數(shù)據(jù)業(yè)務(wù)量的迅速增長和網(wǎng)絡(luò)使用者對網(wǎng)絡(luò)服務(wù)質(zhì)量要求的不斷提高,高可用性已經(jīng)成為衡量高性能網(wǎng)絡(luò)最重要的指標(biāo)之一。目前鏈路聚合技術(shù)通過傳輸鏈路備份可提高網(wǎng)絡(luò)高可用性,已成為必用的組網(wǎng)方案之一。虛擬交換技術(shù)通過增加網(wǎng)絡(luò)拓?fù)渲腥哂喙?jié)點(diǎn)和備份設(shè)計(jì),可大程度提高網(wǎng)絡(luò)高可用性,是網(wǎng)絡(luò)高可用性保障的最優(yōu)解決方案。其具體表現(xiàn)為：將多臺框式分布式設(shè)備虛擬為一臺虛擬設(shè)備,上下聯(lián)設(shè)備通過跨設(shè)備鏈路聚合與虛擬設(shè)備相連,既提供了冗余鏈路,又實(shí)現(xiàn)動(dòng)態(tài)負(fù)載均衡,且充分利用所有帶寬。當(dāng)其中一條物理鏈路出現(xiàn)故障時(shí),切換到另一條鏈路的時(shí)間在毫秒內(nèi)。這樣通過多鏈路備份提高了網(wǎng)絡(luò)的高可用性。另外這種組網(wǎng)方式因無需配置MSTP、VRRP協(xié)議而簡化了網(wǎng)絡(luò)配置。 當(dāng)然虛擬交換技術(shù)也有其不足,即當(dāng)虛擬設(shè)備內(nèi)某兩個(gè)成員設(shè)備間鏈路出現(xiàn)故障時(shí)虛擬設(shè)備發(fā)生分裂,形成兩個(gè)虛擬設(shè)備,出現(xiàn)多激活現(xiàn)象,導(dǎo)致網(wǎng)絡(luò)癱瘓。因此如何快速檢測到多激活及檢測到多激活后該如何處理對于虛擬交換技術(shù)的發(fā)展是極其重要的。目前各個(gè)框式分布式設(shè)備廠商已經(jīng)提出了多激活檢測方法和處理機(jī)制,基于此,本文介紹一種多激活檢測方法和處理機(jī)制,該方法以鏈路聚合技術(shù)中的LACP協(xié)議和虛擬交換技術(shù)為背景,所做工作主要是在軟件層面上對基于LACP的多激活檢測模塊和處理模塊進(jìn)行設(shè)計(jì)與實(shí)現(xiàn)。在對鏈路聚合技術(shù)和虛擬交換技術(shù)進(jìn)行了研究與分析后,本文先對多激活檢測方法和處理機(jī)制原理進(jìn)行了分析,其次對多激活檢測模塊和處理模塊進(jìn)行了總體設(shè)計(jì),然后采用開發(fā)工具進(jìn)行實(shí)現(xiàn),最后在實(shí)驗(yàn)設(shè)備上驗(yàn)證設(shè)計(jì)內(nèi)容是否具有可行性。 通過實(shí)驗(yàn)測試,當(dāng)多激活發(fā)生時(shí),采用本文設(shè)計(jì)的多激活檢測模塊和處理模塊,可檢測到多激活,并可保證網(wǎng)絡(luò)正常運(yùn)行。
[Abstract]:In today's society, with the rapid growth of data traffic and the increasing demand of network users for network quality of service, high availability has become one of the most important indicators to measure high-performance networks. At present, link aggregation technology can improve network high availability through transmission link backup, and has become one of the necessary networking schemes. Virtual switching technology can greatly improve network high availability by adding redundant nodes and backup design in network topology. It is the best solution to guarantee network high availability. Its concrete performance is as follows: the multi-frame distributed device is virtual as a virtual device, and the up-and-down devices are connected to the virtual device through the aggregation of cross-device links, which not only provides redundant links, but also realizes dynamic load balancing. And make full use of all the bandwidth. When one of the physical links fails, the time to switch to the other is within milliseconds. In this way, the high availability of the network is improved through multi-link backup. In addition, the network configuration is simplified because it does not need to configure MSTP,VRRP protocol. Of course, the virtual switching technology also has its shortcomings, that is, when the link between two member devices in the virtual device fails, the virtual device splits, forms two virtual devices, and the phenomenon of multi-activation results in the network paralysis. Therefore, how to quickly detect multi-activation and how to deal with it after detection of multi-activation is very important for the development of virtual switching technology. At present, various distributed device manufacturers have proposed multi-activation detection methods and processing mechanisms. Based on this, this paper introduces a multi-activation detection method and processing mechanism. This method is based on the LACP protocol and virtual switching technology in link aggregation technology. The main work of this method is to design and implement the multi-activation detection module and processing module based on LACP on the software level. After the research and analysis of link aggregation technology and virtual switching technology, this paper first analyzes the principle of multi-activation detection method and processing mechanism, and then designs the multi-activation detection module and processing module as a whole. Then use the development tool to realize, finally verify the feasibility of the design content on the experimental equipment. Through the experimental test, when the multi-activation occurs, the multi-activation detection module and the processing module designed in this paper can be used to detect the multi-activation and ensure the normal operation of the network.
