摘要: 在RFC 5555协议基础上,设计并实现一套双栈移动IPv6环境下以流为粒度的多接口业务流切换方法。利用Linux的XFRM框架、Netfilter框架以及策略路由技术,给出一种多接口移动终端在IPv4和IPv6网络中进行业务流重定向的管理方案,为上层的智能切换判决算法提供一种高效的切换实施方式。实验结果表明,该方法在双栈移动IPv6环境下,能够充分利用网络资源,提高传输效率。

Abstract: This paper designs and implements a per-flow handoff protocol among multiple interfaces in Dual Stack Mobile IPv6(DSMIPv6) based on RFC 5555. This protocol proposes a solution for multi-interface mobile terminal to perform business flow redirection flexibly in IPv4 and IPv6 networks, which utilizes the features of Netfilter, XFRM and policy routing of Linux. It provides more efficient handoff means for intelligent handoff algorithm of higher layers. Experimental results show that flow handoff in DSMIPv6 improves the performance of transmission and takes full advantage of the network resource.
