【摘要】：MPLS_VPN(Multiprotocol Label Switching Virtual Private Network,多协议标签交换虚拟私有网络)是一种新颖实用的网络技术。VPLS(Virtual Private LAN Service,虚拟专用局域网服务)是MPLS_VPN的二层实现。MPLS_VPN能够像传统VPN那样将不同地域的各用户站点组成一个逻辑上的虚拟专用网。通过运营商网络进行隧道连接,MPLS_VPN能为接入该网络的用户提供类似局域网的链接效果。此外它还拥有一些较传统VPN更好的特性:较低的数据开销、较低的开设费用、较简便的维护方式以及更好的安全性。本文主要在以下三方面进行研究。1.通过对MPLS_VPN相关协议的充分研究并分析用户的实际需求,确定目标设备的功能。找到在MPLS_VPN网络条件下接入设备的基本硬件需求。选取合适的硬件设备,结合EDA设计技术,设计出一种即满足用户需求又具有一定拓展潜力的接入硬件平台,为上层应用提供基础。2.研究比较国内外各种MPLS_VPN,尤其是VPLS网络的接入技术,参考用户网络的实际情况和需求,研究了VPLS网络接入的特点和数据格式,据此制定了具体的实现方案,设计并实现了一个基于MAC in MAC技术,同时拥有用户隔离、快速接入、简易配置、优化网络等优秀特性的接入平台。3.利用一个小型实用网络搭建了测试环境,并采取一系列试验证明了该平台的可行性和有效性。当前该接入器设备已正式应用在目标用户网络中,获得很好的使用效果。最后讨论对该应用的优化方法和实现其他应用的途径。在测试环境中实现了大量用户静态路由配置,实现了用户自由入网功能,减少了公网接入设备90%以上的地址存储量,减少了90%以上的配置时间和70%以上的线路铺设费用,取得了极好的实用效果。基于本论文提出的方案设计接入适配设备,可以有效减少网络搭建、管理过程中的配置操作,降低对维护管理时的技术难度,从而有效减少网络的开通成本和运维成本。在为用户提供高效连接的同时还保护用户现有设备价值。该方案的硬件平台具有极大的拓展性,可以在该平台上实现多种MPLS_VPN技术的应用。
[Abstract]:MPLS_VPN (Multiprotocol Label Switching Virtual Private Network, multi-protocol label switching virtual private network) is a novel and practical network technology. VPLs (Virtual Private LAN Service, Virtual Private Local area Network (VPN) is the second layer implementation of MPLS_VPN. VPN can form a logical virtual private network (VPN) from user sites in different regions like traditional VPN. Through the tunnel connection through the operator network, MPLS_VPN can provide the link effect similar to the local area network for the users who access the network. In addition, it has some better features than traditional VPN: lower data overhead, lower opening cost, easier maintenance and better security. This paper mainly studies in the following three aspects. Through the full study of MPLS_VPN related protocols and the analysis of the actual needs of users, the function of the target equipment is determined. Find out the basic hardware requirements of the access device under the condition of MPLS_VPN network. Select the appropriate hardware equipment, combined with EDA design technology, design an access hardware platform that not only meets the needs of users, but also has a certain expansion potential, which provides the basis for the upper application. 2. This paper studies and compares the access technology of various MPLS_VPN, especially VPLS network at home and abroad, refers to the actual situation and requirements of user network, studies the characteristics and data format of VPLS network access, and formulates the concrete implementation scheme. An access platform based on MAC in MAC technology is designed and implemented, which has excellent characteristics such as user isolation, fast access, simple configuration, optimized network and so on. A small practical network is used to build the test environment, and a series of experiments are carried out to prove the feasibility and effectiveness of the platform. At present, the access device has been officially applied in the target user network, and good results have been obtained. Finally, the optimization method of the application and the ways to realize other applications are discussed. A large number of user static routing configurations are realized in the test environment, the function of free access to the network is realized, the address storage capacity of the public network access equipment is reduced by more than 90%, the configuration time is reduced by more than 90%, and the line laying cost is reduced by more than 70%. Excellent practical results have been obtained. Based on the scheme proposed in this paper, the design of access adaptation equipment can effectively reduce the configuration operation in the process of network construction and management, and reduce the technical difficulty of maintenance management, so as to effectively reduce the opening cost and operation and maintenance cost of the network. It not only provides efficient connection to users, but also protects the value of existing devices. The hardware platform of this scheme has great expansibility, and it can realize the application of many kinds of MPLS_VPN technology on this platform.
