【摘要】：随着MPLS VPN技术在城域网上的广泛部署和使用,该技术可以满足不同用户对实时语音、在线视频、海量数据以及其他Internet业务的需求。基于MPLS所构建VPN的网络,利用公网路由来传递私网VPN路由并对各VPN业务流量进行有效的隔离,从而为各企、事业单位的信息化提供了高效的保证,所以城域网MPLS VPN网络如何提升差别化Qos的服务水平成为关注的热点。本文将对MPLS的Qos区分模型和MPLS流量工程进行研究。 本文首先从MPLS的概念和基本原理着手,介绍了MPLS VPN网络VPNV4路由的传递过程以及MBGP/MPLS VPN的实现技术。其次通过对MPLS VPN的QOS和流量工程进行分析和研究,给出了MPLS VPN网络中MPLS区分服务的实现模型和感知区分服务的流量工程实现的解决方案。最后根据不同的网络应用环境和全网可用带宽资源情况,阶段性的对MPLS DifferServ、MPLS流量工程和DS-TE技术实施部署。 依托仿真的网络实验室条件,结合某省运营商的城域网网络建设项目,优化了MPLSVPN网络部署的方案,并从该城域网现有的NGN、VPN、互联网专线业务以及未来即将开展的IPTV等业务的差异化需求为出发点,以用户的最终最优的主观体验为目标,对MPLSDifferServ及感知区分服务的流量工程进行部署。根据现网的实际业务应用,在实验环境中设计了三种MPLS VPN网络Qos的部署场景,并对实验数据进行分析,为下一阶段城域网Qos部署提供重要依据。
[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.
