【摘要】 IPv6作为下一代互联网的网络层协议,将逐渐替代目前使用的IPv4,成为互联网的主流协议。由于工Pv6协议在IPv4的基础上做了很多改进,使得网管工作的重要组成部分—拓扑发现的原理和方法也有了很多改变。本文主要对AS域内IPv4&IPv6网络共存环境下的拓扑发现技术和系统作研究。论文在对IPv6协议以及网络拓扑自动发现的相关技术进行深入研究的基础上,提出了IPv4&IPv6共存网络环境下进行拓扑发现出现的新问题；然后重点研究工Pv4&IPv6共存网络拓扑发现的关键技术,如隧道的发现与验证、匿名路由器、交叉冗余链路、对等地址归并等；设计了一个自治系统中IPv4&IPv6共存网络拓扑发现原型系统,该系统可以发现自治系统中大部分的骨干网路由器,包括这些路由器间的相互连接关系；还可以发现本地链路子网内的所有路由器和主机,以及这些设备的配置信息。最后,在实验室和某AS域中进行数据测试,并分析和验证了该系统的正确性和有效性,其结果满足设计要求。本文的工作比较好地解决了AS域中工Pv4&IPv6共存网络的拓扑自动发现问题,对IPv4&IPv6一体化综合网络管理系统的研究具有较好的参考价值,为IPv4&IPv6共存网络管理及其网络拓扑研究提供了一个很好的实现方案。更多还原

【Abstract】 As a next-generation Internet’s network layer protocol, IPv6 will gradually replace the currently used protocol:IPv4, become to the mainstream Internet protocol. IPv4 IPv6 protocol as the basis to do a lot of improvements, making the work an important part of network management-principles and methods of topology discovery has also been many changes. This paper mainly does research on IPv4 and IPv6 coexisting network within AS for topology discovery technologies and a prototype system.This paper proposes the new problems in topology discovery within IPv4 & IPv6 coexistence network environment based on the in-depth study of the relevant technologies of IPv6 protocol and network topology auto-discovery; Then focuses on the topology discovery key technologies within IPv4 & IPv6 coexistence network, such as tunnel discovery and verification, anonymous routers, cross-redundant link, router alias discovery and merging and so on; Designs a topology discovery prototype system within the IPv4 & IPv6 coexisting network, The system can automatically find the majority of AS backbone routers and the connection of the link between these routers, can find the configuration information of the local routers and hosts. Finally, a series of tests performed in the laboratory and AS field, verify the correctness and effectiveness of the prototype system, The results meet the design requirements.This work properly solves the topology auto-discovery problems base on IPv4 & IPv6 coexisting network within AS, is of reference to the integrated network management system studies within IPv4 & IPv6 coexisting network, and provides a good implementation of the topology discovery approach within the coexisting network.更多还原
