【摘要】 移动IPv6的提出使得网络节点的透明性移动成为了可能,即移动节点在接入新的子网时,不需要变动自己的IP地址便能享有新的网络域的资源并且保持与原来网络的连接,这为移动计算和移动办公提供了一个很好的解决规范。但移动IPv6在切换过程中的延时和中断却不能满足越来越多的多媒体,即时通讯等实时应用的要求。 论文的开始部分详细讨论分析了快速层次移动IPv6框架,是对现有的研究技术进行了综合和改进而提出的解决方案,它有效地缩短了移动节点在切换过程中的延时,使移动节点在不同子网切换过程中达到“无缝切换”的效果,是移动IPv6推广应用的关键。 为了适应越来越多的多媒体及实时应用,使得移动节点在切换过程和切换之后仍然能够有效地享有服务质量的保证,就需要引入服务质量保证的解决方案。本文后面部分详细介绍了现今网络下实现QoS的主要模型,研究了其在移动环境下遇到的问题,综合并改进了MRSVP协议及相关技术,并提出了基于快速层次移动IPv6下的服务质量保证解决方案,并给出了模拟实验环境下的性能对比分析,这对于移动IPv6以后的实际应用是一个重要的保证。更多还原

【Abstract】 The Mobile IPv6 specifies a protocol which allows nodes to remain reachable while moving around in the IPv6 Internet. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. This makes the so-called movement work very convenience. However, there is a period during which the Mobile Node is unable to send or receive packets because of link switching delay and IP protocol operations.This is known as the "handover lantancy".To solve the handover lantancy problem is becoming important in Mobile IPv6 application. This paper describes a resolution of F-HMIPv6 to improve handover latency due to Mobile IPv6 procedures. And the resolution is a contribution to the Mobile IPv6 application as it works well.These days,the real time service of new applications, including teleconferencing, remote seminars, and distributed simulation, become more and more popular. This is another challenge to the Mobile IPv6 application. So it is necessary to integrate the QoS into it. This document specifies a resoluction of QoS based upon the F-HMIPv6, to meet the growing need for real-time service under Mobile IPv6 environment.更多还原
