摘要

由于移动节点的位置是不断变化的

移动IPv6协议给出了支持移动节点的远程加入和双向隧道两种组播方法

但这两种方法都有各自的缺点.本文提出基于移动预测的快速分层移动组播体系结构(mobility prediction based fast and hierarchical mobile multicast architecture

简称MP-FHMM)

通过移动预测

在切换前为移动节点配置好切换信息

并且在切换时使用基于FMIPv6改进的快速组播切换方法

有效减少了切换延迟以及由此引发的组播数据分组丢失.另外

由于采用层次型结构的移动组播管理

屏蔽了节点在子网内的移动

减少了因节点移动而重构组播树的频率.

Abstract

As mobile nodes dynamically change their locations

Mobile IPv6 offers two methods of multicast services for mobile nodes

which are called remote subscription and bi-directional tunnel

but they both have shortcomings.This paper proposed a mobility prediction based fast and hierarchical mobile multicast architecture (MP-FHMM)

which could configure the handoff information by predicting the mobility of the nodes before multicast handoff

and uses the improved FMIPv6 handoff method when mobile nodes are playing handoff.This architecture reduces handoff latency and packet loss rate causing by handoff.In addition

it uses a hierarchical architecture to isolate the subnet movement from outside

which reduces the frequency of rebuilding multicast tree because of nodes’ mobility.
