摘要
传统互联网以'固定、有线'为主的连通方式,难以适应新的无线/移动网络的发展需求.本文提出了一种新一代互联网移动管理机制——标识分离映射机制ISMS,详细介绍了ISMS的基本理论和协议流程,并与移动IPv6协议进行了性能分析和对比.ISMS是一种基于网络的移动管理机制,其切换管理和位置管理均由网络完成,能够满足新一代互联网移动管理机制在快速切换、路由优化、可扩展、可控可管、保护位置隐私、安全性和降低无线链路开销等方面的需求.理论分析表明ISMS的网络层面平均切换时延远小于移动IPv6的平均切换时延,能够有效支持绝大部分实时应用.原型系统的实现和验证进一步说明了ISMS的可行性和有效性.
Traditional Intemet was originally designed for statically located terminals and can hardly meet the new requirements of wireless/mobile networks. This paper proposes a candidate for the mobility management scheme in future Internet, named Identifiers Separating and Mapping Scheme （ ISMS）, discusses its basic theory and detailed approaches, and compares it with Mobile IPv6. ISMS is a network - based mobility management scheme which deploys location management and handover management inside of the network. It is also designed to satisfy the needs of faster handover, route optimism, scalability, controllability, location privacy, security and decreasing consumption on wireless links. Analysis shows that the average handoff delay of ISMS is far smaller than that of Mobile IPv6 and can satisfy most of the real - time applications. Experiments performed on a prototype show that ISMS is feasible and effective.
