摘要/Abstract

摘要： 针对移动网络应用在代理移动IPv6域中存在切换时延大并且缺乏对域间切换有效支持的问题,提出一种基于PMIPv6的移动网络快速切换方案。该方案通过结合二层机制在移动节点完成注册之前进行预切换,提前获取节点信息,建立缓存数据转发隧道,利用扩展的信令消息进行不同域间实体的交互,实现对域间切换的有效支持,并引入双重缓存机制,避免了切换过程中的分组丢失。分析和仿真结果表明,本方案相对传统机制,降低了系统切换时延。

Abstract: A PMIPv6based fast handover scheme for NEtwork MObility was proposed to solve the problem of long handover delay and lack of effective inter-domain handover scheme to support NEtwork MObility in Proxy Mobile IPv6Network．With the help of L2scheme to perform pre-handover before mobile node getting registered,information is acknowledged and tunnel for buffering packets is established in advance．Inter-domain handover is supported by extending signaling to make entities communication in different domain and eliminates the packet loss problem by introducing double buffering scheme．Analysis and simulation show that this proposal can reduce the delay during handover compared to the existing mechanisms.
