【摘要】：随着Internet规模不断的扩大，用户对网络的使用也提出了新的要求。但是由于互联网对数据的稳定性还没有太好的办法，网络流量的控制就难以保证。当Internet达到一定规模后，，Internet将在很多领域（流量，稳定，网络地址，安全）存在着威胁，这些问题对于目前的技术来讲是很难解决的。如何将IP技术与ATM技术更好的融合，更好的实现路由与交换的作用，应该是现在研究的中心。很多网络服务商以及一些研究者提出了很多解决的方法，其中多协议标记交换（MPLS）技术被提出之后，才让大家重新有了新的方向。多协议标记交换（MPLS）是新一代的网络交换标准，它不仅具有第二层标记交换的特点，而且它还具有第三层路由的特性，通过把二层的数据链路协议与三层的路由转发技术应用到一起，在目前的网络状况下，这样的解决方案对数据分组转发中的问题有很大的帮助。架构MPLS VPN网络就是它的一个主要解决方案。论文首先介绍了相关技术的背景及其特点，同时对MPLS的网络结构、技术规则等方面进行了一些具体的研究和讨论。同时对在实际应用中存在的问题提出了相应的解决方案，在掌握以上知识和理论的基础上，并按照相关企业的网络特点，完成了一个MPLS VPN企业网络实例。进行有针对性的分析，构建一个基于MPLS VPN体系结构的企业内部网络拓扑，配置相关的网络设备。
[Abstract]:With the continuous expansion of Internet scale, users also put forward new requirements for the use of the network. However, because the stability of the Internet to the data is not too good, it is difficult to guarantee the control of network traffic. When Internet reaches a certain scale, there will be threats in many fields (traffic, stability, network address, security). These problems are difficult to solve for the current technology. How to integrate IP technology and ATM technology better, better realize the role of routing and switching, should be the center of current research. Many network service providers and some researchers have put forward a lot of solutions. After the multi-protocol label switching (MPLS) technology was put forward, it was only then that we had a new direction. Multiprotocol label switching (MPLS) is a new network switching standard. It not only has the characteristics of layer 2 label switching, but also has the characteristics of layer 3 routing. Through the application of layer 2 data link protocol and layer 3 routing and forwarding technology, under the current network conditions, this solution is of great help to the problem of data packet forwarding. MPLS VPN network architecture is one of its main solutions. Firstly, the background and characteristics of related technologies are introduced. At the same time, the network structure and technical rules of MPLS are studied and discussed in detail. At the same time, the corresponding solutions to the problems in practical application are put forward. On the basis of mastering the above knowledge and theory, and according to the network characteristics of related enterprises, a MPLS VPN enterprise network example is completed. A network topology based on MPLS VPN architecture is constructed and related network devices are configured.
