摘要: 现有IPv4网络的IP地址空间、安全性和服务质量控制等问题,限制了Internet应用的发展,研究IPv6的相关技术,可以推动下一代网络的建设和发展.针对移动IPv6在切换过程中出现的数据包丢失和切换延迟问题,分析了相关的快速、平滑切换和分级管理3种解决方案,并结合IETF草案文档建议,设计实现了一个基于MIPL(Mobile Ipv6 for Linux)的、具有平滑切换性能的移动IPv6切换框架.框架采用将切换过程和缓存管理相分离的松耦合模式,可有效地增强应用系统的可扩展性和可移植性,为基于移动IPv6网络的实时应用系统信息的可靠传输提供一种有效途径.

Abstract: IPv4-based networks are faced with many problems like the lack of IP address, less security, and so on, which have limited the development of Internet, therefore, it is important to study the techniques of IPv6, so as to promote the construction of the next generation of Internet. The problems of handover latency and lost packets of mobile IPv6 were discussed, in which, the three extension techniques in current mobile IPv6 protocols, namely as fast handover, smooth handover and hierarchical mobile IPv6, were firstly analyzed. And then, based on the IETF drafts, a framework with smooth handover technique was brought forward. In this framework, the handover process and the buffer management worked at different levels respectively, which would improve the expansion and portability of the application systems. This framework would be viewed as an effective method to transport reliably the real-time information of the application systems working in mobile IPv6 environment.
