快速层次移动IPv6协议的比较性能评价

本文用ns-2网络模拟器给出了一种F-HMIPv6协议与MIPv6、HMIPv6、FMIPv6、FHMIPv6（HMIPv6与FMIPv6的简单结合）的比较性能分析。通过仿真实验检测了MN从一个子网移动到另一子网发生切换时的延时与丢包性能。从实验结果可知，它们的延时和丢包性能从优到劣的顺序依次为：F-HMIPv6、FHMIPv6、FMIPv6、HMIPv6和MIPv6。     

A framework for end-to-end RSVP context transfer in mobile IPv6

A framework for end-to-end RSVP context transfer in Mobile IPv6（MIPv6） based on the architecture of F-HMIPv6 is proposed in this paper. The scheme provides an end-to-end RSVP context transfer for real-time applications to overcome the weakness of Context Transfer Protocol which can not meet the need of end-to-end QoS mechanisms because contexts are only transferred between Access Routers（ARs）, therefore they can promptly get the same forwarding process, minimize the handover service disruption, and avoid initiating the end-to-end RSVP signaling from scratch after an MN performs handovers. It may also reduce the signaling overhead and handover latencies by adopting the F-HMIPv6architecture. The performance of the approach is compared with the re-initiating RSVP signaling to re-establish QoS states using network simulator, and the numerical results show that the scheme has the less latency and packet loss than that of the re-initiating approach.     

QoS接纳控制算法性能分析与比较

对5种QoS接纳控制算法进行性能分析和比较。论文在NS2中构建了实验用的网络拓扑和流量，在RSVP信令下，对3种不同带宽利用率的网络场景进行了仿真，并对以上算法在各种场景下的丢包率、接入率、传输时延和时延抖动情况进行了分析和比较。     

一种基于VLAN划分的MIPv6仿真实验环境

介绍了一种移动IPv6实验系统。该系统建立在局域网环境中，移动节点漫游切换的实现采用了不同于传统手工拔插线或修改ESSID的方法，即通过在交换机中划分VLAN来实现。介绍了实验系统的构成、移动节点切换以及系统控制程序的实现。实验结果表明，与传统切换方式相比，采用基于VLAN的切换方式不仅使MN的切换更加方便、快速，而且使MN切换过程中的丢包和时延也都得到了改善。
