毕业设计论文-一种基于dmvpn技术的网络平台的设计论文

摘 要

随着现代社会生活与信息技术的发展，福利彩票销售系统面临着过度依赖于传统IPSEC VPN的手工配置静态隧道、不支持隧道动态获取IP地址，网络中流量负载均衡、数据安全性能有待提高等问题，严重制约着福彩事业的进一步发展。

本文在A市福利彩票系统网络平台改造项目的实践基础上，采用目前流行的DMVPN(Dynamic Multipoint VPN，动态多点VPN)技术针对以上问题提出了一种有效的解决方案。在该方案中使用了mGRE（Multipoint GRE,多点GRE）和NHRP（Next Hop Resolution Protocol，下一跳解析协议），结合IPSec，较好地解决原来的网络平台存在的问题。经试运行表明，这种网络平台解决方案能给予福彩系统良好的支撑。

ABSTRACT

With the development of modern social life and information technology, welfare lottery sale system are facing many problems. Such as it highly relies on the traditional IPSEC VPN and need handling the static tunnel by man, while it does not support the tunnel to gain the IP address accordingly; the balance of the flow on the internet and the safety of the data need be improved and so on. All of these problems restrict the improvement of welfare lottery affairs. Based on the practice of on-line stage improving project of welfare lottery sale system in city A, we find a more efficient plan to solve these problems by using the most popular DMVPN(Dynamic Multipoint VPN) technology. In our plan we used mGRE(Multipoint GRE) and NHRP(Next Hop Resolution rotocol), to combine with IPSec, after testing we found it did work.

Key words: mGRE; NHRP; DMVPN
