移动IP/IPv6中移动检测的研究

The Research of Movement Detection of Mobile IP/IPv6

目前,移动IP/IPv6只适合于宏移动环境,其主要原因是切换时延过长,难以保证切换期间原有会话不中断和达到零分组丢失的目标。能否缩小切换时延决定了移动IP/IPv6是否适应微移动环境,而移动检测机制是移动IP/IPv6中影响切换时延的一个主要因素。本文就移动IP、IPv6中的移动检测机制作研究,提出了数据链路层触发检测以及扩展IRDP和RA报文的移动检测方案。

The mobile IP/IP_v6 is only suit for the'macro'movement at prrsent.Because of its switching delay,it the most important for mobile IP/IP_v6 in 'micro'movement environment.Movement Detection is one of main factos of the switching delay,and the paper will propose that extending the IRDP or RA packet and associating data link layer to perfom movment detection help the switching delay.
