基于IPv6的MPLS VPN研究
|
摘要
随着Internet迅速的发展以及CNGI(中国下一代互联网示范工程)核心网的开通,IPv6将逐渐取代IPv4。实践也表明IPv6网络协议比IPv4不仅在网络IP地址枯竭问题的完美解决上,而且在网络管理、运行、控制、处理等许多性能上更为强大、高效。MPLS(Multi-ProtocolLabel Switching)即多协议标记交换,是一个网络层包转发新兴标准,作为一种新的Internet骨干网技术,它的实现可以简化IPv6的实施。MPLS技术是集成的路由/交换解决方案的最新进展,它无缝地集成了IP路由技术的灵活性和二层交换的简洁性,将交换机与路由器的优点完美地结合在了一起,把IP技术的灵活性、可扩展性与ATM等技术的高性能、流量控制功能很好地结合起来,成为当前业界普遍关注的热点。而以MPLS虚拟专用网络(VPN,Virtual Private Network)为主的IP VPN技术是一种灵活的VPN解决方案,其简单方便、可扩展的特性使它在众多VPN技术中独具特色。因此,基于IPv6的MPLS/VPN研究更具有广泛应用前景,具有很强的实用性。在学术上,具有很强的前沿性和前瞻性。
论文首先介绍了IPv6以及基于IPv6的MPLS VPN基本运行机制等相关知识,然后从三个方面详细介绍了本课题所做的主要工作。
(1)6PE实现IPv4向IPv6过渡。
(2)综合型的MPLS QoS在IPv6下的实现。
(3)MPLS VPN在移动IPv6下的实现。
论文最后提出了研究的不足之处,并针对研究的不足作了下一步研究工作计划。该课题以理论研究方式为基础,以真实环境实验和模拟实验为核心的方案进行研究,紧跟网络新技术的最新发展方向。
With the rapid development of Internet and the CNGI(China Next Generation Internet Demonstration Project)to open the core network,IPv6 will gradually replace IPv4.Practice also shows that the network protocol IPv6 is much more powerful and efficient than IPv4 networks not only in the IP address depletion problem on the perfect solution,but also in the performance of the network's management,operation,control and treatment.MPLS(Multi-Protocol Label Switching) is a network layer packet forwarding emerging standards,as a new Internet backbone network technology,which can simplify the implementation of IPv6.MPLS technology is the latest development of the integrated routing/switching solutions,which seamlessly integrates the flexibility of IP routing technology and the simplicity of the second floor of the exchange,and combine the advantages of switches and routers perfectly.It also combines the flexibility, scalability of IP technology with high-performance technologies such as ATM,traffic control functions well,it will become the current hot topics of common concern to the industry.By MPLS VPN(Virtual Private Network)-based IP VPN technology is a flexible VPN solution.Its features such as convenience and scalability make it a unique one among the numberous VPN technology. Therefore,based on IPv6,MPLS/VPN's study has the prospect of a more widely used,and highly practical.Academically speaking,it has a very leading edge and forward-looking.
The paper first introduces IPv6 and the basic operational mechanism of MPLS VPN based on IPv6,the related knowledge and so on,and then introduces in detail the major work of the paper from three aspects.
1) 6PE implements over IPv4 to IPv6.
2) In the implementation of synthetic MPLS QoS based on IPv6.
3) In the implementation of MPLS VPN based on mobile IPv6.
The paper proposes finally the research deficiencies,and makes a work plan for further studies to be aimed at the research deficiencies.This paper take the fundamental research way as a foundation,conducts the research taking the true environment experiment and the simulation experiment as the core plan,follows close on the network new technology the most recent development direction.
