【摘要】：隨著MPLS VPN技術(shù)在城域網(wǎng)上的廣泛部署和使用,該技術(shù)可以滿足不同用戶對實時語音、在線視頻、海量數(shù)據(jù)以及其他Internet業(yè)務(wù)的需求。基于MPLS所構(gòu)建VPN的網(wǎng)絡(luò),利用公網(wǎng)路由來傳遞私網(wǎng)VPN路由并對各VPN業(yè)務(wù)流量進行有效的隔離,從而為各企、事業(yè)單位的信息化提供了高效的保證,所以城域網(wǎng)MPLS VPN網(wǎng)絡(luò)如何提升差別化Qos的服務(wù)水平成為關(guān)注的熱點。本文將對MPLS的Qos區(qū)分模型和MPLS流量工程進行研究。 本文首先從MPLS的概念和基本原理著手,介紹了MPLS VPN網(wǎng)絡(luò)VPNV4路由的傳遞過程以及MBGP/MPLS VPN的實現(xiàn)技術(shù)。其次通過對MPLS VPN的QOS和流量工程進行分析和研究,給出了MPLS VPN網(wǎng)絡(luò)中MPLS區(qū)分服務(wù)的實現(xiàn)模型和感知區(qū)分服務(wù)的流量工程實現(xiàn)的解決方案。最后根據(jù)不同的網(wǎng)絡(luò)應(yīng)用環(huán)境和全網(wǎng)可用帶寬資源情況,階段性的對MPLS DifferServ、MPLS流量工程和DS-TE技術(shù)實施部署。 依托仿真的網(wǎng)絡(luò)實驗室條件,結(jié)合某省運營商的城域網(wǎng)網(wǎng)絡(luò)建設(shè)項目,優(yōu)化了MPLSVPN網(wǎng)絡(luò)部署的方案,并從該城域網(wǎng)現(xiàn)有的NGN、VPN、互聯(lián)網(wǎng)專線業(yè)務(wù)以及未來即將開展的IPTV等業(yè)務(wù)的差異化需求為出發(fā)點,以用戶的最終最優(yōu)的主觀體驗為目標(biāo),對MPLSDifferServ及感知區(qū)分服務(wù)的流量工程進行部署。根據(jù)現(xiàn)網(wǎng)的實際業(yè)務(wù)應(yīng)用,在實驗環(huán)境中設(shè)計了三種MPLS VPN網(wǎng)絡(luò)Qos的部署場景,并對實驗數(shù)據(jù)進行分析,為下一階段城域網(wǎng)Qos部署提供重要依據(jù)。
[Abstract]:With the wide deployment and use of MPLS VPN technology in man, this technology can meet the needs of different users for real-time voice, online video, massive data and other Internet services. Based on the VPN network built by MPLS, the private network VPN route is transmitted by public network routing and the traffic of each VPN service is effectively isolated, which provides an efficient guarantee for the informationization of enterprises and institutions. So how to improve the service level of differential Qos in metropolitan area network (man) MPLS VPN has become a hot spot. In this paper, the Qos differentiation model and MPLS traffic engineering of MPLS are studied. This paper begins with the concept and basic principle of MPLS, introduces the transfer process of VPNV4 routing in MPLS VPN network and the implementation technology of MBGP/MPLS VPN. Secondly, through the analysis and research of QOS and traffic engineering of MPLS VPN, the implementation model of MPLS differentiated service in MPLS VPN network and the solution of realizing traffic engineering of perceived differentiated service are given. Finally, according to the different network application environment and the available bandwidth resources of the whole network, the MPLS DifferServ,MPLS traffic engineering and DS-TE technology are deployed in phases. Based on the network laboratory conditions of simulation, combined with a provincial operator's metropolitan area network construction project, the scheme of MPLSVPN network deployment is optimized. From the view of the existing NGN,VPN, dedicated line service of the Metropolitan area Network (man) and the needs of the future IPTV and other services as the starting point, and taking the final optimal subjective experience of the user as the goal, this paper deploys the traffic engineering of MPLSDifferServ and perceptual differentiated service. According to the actual service application of the present network, three kinds of MPLS VPN network Qos deployment scenarios are designed in the experimental environment, and the experimental data are analyzed, which provides an important basis for the next stage of the metropolitan area network (man) Qos deployment.
