【摘要】：随着近年来Internet网络的不断发展,随时随地移动办公成为越来越多用户的需求。VPDN英文全称“Virtual Private Dial-up Networks",网络组建中用户主点采用专线方式接入,远端用户通过拨号方式接入,是基于运营商无线网络全覆盖建构的虚拟专用拨号网络。基于MPLS VPN的VPDN组网的建设要求具备AAA认证和授权机制,融合了MPLS VPN和VPDN技术的优点,具有系统灵活且安全可靠、操作简便、管理便捷等特点。本文首先对基于MPLS VPN的VPDN网络关键技术进行了综述,包括MPLSVPN的标签转发、LNS复用、加密技术、QoS技术和VPDN的核心技术。其中MPLS-VPN的LNS复用思想解决了不同种类LNS路由配置的兼容复杂性,将系统的复杂性集中在ISP一端,ISP中LAC服务器只需与1-2台LNS设备互通,用户只需接入MPLS VPN网络即可完成网络部署,新增用户时,不需要重新进行LAC和LNS之间的互通测试。隧道技术建立在用户网关和接入服务器之间,负责把用户内网和公网的数据流量分开,远程接入用户可通过隧道登录到企业内网中。基于MPLS VPN的VPDN网络技术融合了MPLS VPN和传统VPDN的网络优点,既降低了企业投资和维护成本,并兼有MPLS VPN组网的安全灵活性。本文其次介绍了农村信用社VPDN网络的组建背景、基于MPLS VPN的VPDN网络体系的选用,并重点从MPLS VPN技术、无线网络安全技术和用户侧网络安全技术的角度对基于MPLS VPN的VPDN网络良好安全性能进行了分析。本文最后对基于MPLS VPN的VPDN网络在农村信用社的具体应用进行了研究,并从平台的搭建、设备的采购、网络设备部署和安全性能等方面进行了详细阐述,同时进行了系统测试,确保系统的可用性、灵活性。本文也对农村信用社网络正常使用过程中出现的障碍问题进行了分析总结。基于MPLS VPN的VPDN网络在实际应用中有重要的价值和深远的前景。
[Abstract]:With the development of Internet network in recent years, mobile office has become the demand of more and more users. VPDN is called "Virtual Private Dial-up Networks" in English. The construction of VPDN network based on MPLS VPN requires the mechanism of AAA authentication and authorization, which combines the advantages of MPLS VPN and VPDN technology, and has the advantages of flexibility, security and reliability. This paper first summarizes the key technologies of VPDN network based on MPLS VPN, including MPLSVPN label forwarding, LNs multiplexing, and so on. Among them, MPLS-VPN 's LNS reuse idea solves the compatible complexity of different kinds of LNS routing configuration, and the complexity of the system is concentrated in the ISP end of ISP. The LAC server only needs to communicate with 1-2 LNS devices. Users only need to access the MPLS VPN network to complete the network deployment. When adding new users, there is no need to re-test the interworking between LAC and LNS. The tunneling technology is built between the user gateway and the access server. It is responsible for separating the data flow of the user's intranet from the public network, and the remote access user can log in to the enterprise's intranet through the tunnel. The VPDN network technology based on MPLS VPN combines the advantages of MPLS VPN and traditional VPDN, which reduces the cost of enterprise investment and maintenance. It also has the security flexibility of MPLS VPN network. Secondly, this paper introduces the background of setting up VPDN network of rural credit cooperatives, the selection of VPDN network system based on MPLS VPN, and focuses on MPLS VPN technology. From the point of view of wireless network security technology and user-side network security technology, the good security performance of VPDN network based on MPLS VPN is analyzed. Finally, the application of VPDN network based on MPLS VPN in rural credit cooperatives is studied. And from the platform construction, equipment procurement, network equipment deployment and security performance are described in detail. At the same time, the system is tested to ensure the availability of the system. Flexibility. This paper also analyzes and summarizes the obstacles in the normal use of rural credit cooperative network. The VPDN network based on MPLS VPN has important value and far-reaching prospect in practical application.
