摘要
IETF提出的移动IP支持移动节点进行全球的INTERNET上的移动,但是当移动节点进行微移动时,现有的移动IP方案会在网络中产生大量的注册报文,降低网络性能,造成较大的注册延时,从而引起严重的包丢失和通信吞吐量下降,因此有必要加以改进。文章介绍了三级模型、CellularIP和HAWAII等三种改进的移动性IP协议,并进行了详细分析。
The IETF Mobile IP standard is intended to solve the general problem of host mobility in the global Inter-net.When mobile devices crossing cell boundaries frequently(micro mobility),the standard Mobile IP will result in fre-quent location updates and degradation of network performance,as well as the latency involved in the re-routing of the packets the loss of packets.Therefore the standard Mobile IP must be improved to adaptive this situation,i.e.micro mo-bility.In this paper,three typical improved Mobile IP protocols are introduced and deeply analyzed,and it will be help-ful for the further solution of this problem.
