摘　　要：随着移动互联网技术的发展,人们希望在移动过程中获取Internet服务,如何采用NEMO(NetworkMobility)技术为列车等移动子网提供移动性支持成为一个研究热点。当前,越来越多的移动设备具有多种网络接口,可同时接入Internet获取服务。采用多接口技术可以有效地扩大终端或子网的移动范围,提高传输的可靠性,并实现负载均衡。但是,当前的NEMO协议只提供单一接口上的移动性支持,而无法实现多接口的移动性支持。本文在研究多接口移动网络的基础上,提出并实现了一种基于多接口NEMO的子网移动性支持方案,采用多种连接方式为列车等移动子网提供服务。为了测试该方案的性能,搭建了一个实验环境。实验结果表明,该方案能够为移动子网提供全局的移动性支持,并可以在多个接口之间实现无缝切换。Along with the development of wireless and mobile technologies, many people want to get the Internet services when they are moving. How the NEMO （network mobility）-based technology is applied to provide mobile support for mobile networks such as train networks becomes a hot spot in research. Nowadays, more and more mobile devices are equipped with multiple interfaces which can be connected into internet to provide reliable transmission and realize load balance. However, the current NEMO protocol provides only mobile support at a single interface instead of at multiple interfaces. So, in this paper, the multiple-interfaces-based NEMO mobile support scheme is proposed, which uses multiple interfaces to provide Internet services for mobile networks. A test-bed is set up to evaluate the performance of the scheme. The experimental results indicate that the proposed scheme can provide global mobile support and realize seamless handover among multiple interfaces.
