【摘要】 随着全球网络技术的迅速发展,以IPv4为核心协议的第一代互联网所面临的地址紧缺、安全性不够、缺乏服务质量保证等一系列诸多问题,以及移动业务需求的迅速增长,促进了世界各国对IPv6为核心协议的下一代互联网的研究。IPv6几乎无限的地址空间、支持即插即用、强大的安全性、对移动技术的广泛支持等优点,使IPv6取代IPv4成为未来网络发展的必然。在此背景下,黑龙江省交通系统在未来网络建设规划时,必须考虑到对高性能网络日益增长的应用和需求,考虑到由IPv4网络向IPv6网络过渡时,过渡机制的选择和过渡方案的设计等问题。本论文从IPv6的技术理论分析入手,对现有IPv4-v6综合组网的三种关键技术(即双协议栈技术、隧道技术及翻译策略)进行了深入的研究,分析了这三种技术的实现机制、常用的配置方法及各自的优缺点,按照逐步演进的过渡策略,将IPv4-v6网络过渡过程划分为四个阶段,在每个阶段中按照IPv4主机与IPv6主机在网络中的不同存有比例和应用环境等,合理选择相应的技术手段,综合使用了这三种关键技术,完成了IPv4-v6综合组网方案的设计。在此基础上,经过对黑龙江省交通网络现状及对IPv6组网相关技术原理和下一代网络组网建设原则、设计需求全面分析的前提下,按照方案的设计思想设计出黑龙江省交通网络IPv4-v6综合组网方案。方案中明确了在黑龙江省交通网络IPv4-v6过渡阶段的主干网设计、接入网设计、客户端设计、路由协议设计、域名解析部署、网络安全规划、设备选型方案等问题,并规划出黑龙江省交通网络IPv6地址分配策略,为将现有的黑龙江省交通网络环境平滑顺利的由IPv4网移植到IPv6网络上提供了依据。更多还原

【Abstract】 There are many problems regarding address,sagety,and service quality guarantee facing the first generation of network with IPv4 as the core protocol. These problems along with the quick development of mobile business demand have promoted all the countries in the world to study the next generation of network with IPv6 as the core protocol.There are many advantages with IPv6,such as almost limitless address space, supporting plug and play,strong safety quality,broadly supporting mobile technics.So it is inevitable that IPv6 will replace IPv4.Under this background, when design the network construction,Heilongjiang communications system must think about the more and more apply and demand of high qulity network.It must think about the design of transition mechanism and project.This article research on the three key technics,include double protocol stack technology,tunnel technology and translation strategy.It analyzes the realizing mechanism,in common used configuration methods of the three technologies.It provides IPv4-6 network transition course to four steps.In each steps,it choices relevant technology methods according to different proportion and apply circumstance of IPv4 and IPv6.It synthesized used the three key technologies and complete the design of IPv4-v6 synthesized network project.On the basis of the research,this article analyzes Heilongjaing communications network,the relavent IPv6 network technology theory,the next network construction principles and demand for design.It provides the Heilongjiang communications network synthesized network project.The project explains many problems during the transition step of Heilongjiang communication network IP4-6,such as main network design, connect network design,client point design,route agreement desigh,domain name analyzed dispose,network safety design,equipment choice project,and so on.It makes out the address distribute policy of Heilongjiang communications net work IPv6.It provides the foundation of now network circumstances transfer from IPv4 to IPv6 of Heilongjiang communications network circumstance.更多还原
