最近提出了几种支持IP移动性的架构。然而，大多数研究表明，目前的协议总体上不能满足音频应用的性能要求。在这项研究中，我们提出了一种基于组播的协议，以减少切换过程中的时延和丢包，为IP移动性支持提供基础。我们使用大量的仿真来评估我们的协议在各种真实和生成的拓扑上的性能，并将其与其他几种移动协议，特别是移动IP协议进行了比较。我们将切换延迟估计和路由效率作为比较的指标。我们在研究中采用了路由分析(而不是数据包分析)方法，并将其应用于广域网环境中。我们的仿真结果表明，我们提出的协议有显著的改进。平均而言，基本移动IP消耗的网络带宽几乎是我们建议的协议的两倍，并且经历的端到端和切换延迟是我们建议的协议的两倍多。此外，即使在路由优化的情况下，我们的协议的平均切换延迟估计也比其他协议要小。我们进一步提出了对移动IP协议的扩展，以支持我们的协议，并且只需最小的修改。
Several architectures have been recently proposed to support IP mobility. Most studies, however, show that current protocols, in general, fall short from satisfying the performance requirements for audio applications. In this study, we propose a multicast-based protocol to reduce latency and packet loss during handoff and provide the base for IP mobility support. We use extensive simulation to evaluate our protocol's performance over a variety of real and generated topologies, and we compare it to several other mobility protocols, especially the Mobile IP protocols. We take handoff delay estimates and routing efficiency as metrics for our comparisons. We take a route analysis (as opposed to packet analysis) approach in our study, and we apply it in the context of wide-area networks. Our simulation results show significant improvement for our proposed protocol. On average, basic Mobile IP consumes almost twice as much network bandwidth, and experiences more than twice as much end-to-end and handoff delays, as does our proposed protocol. In addition, average handoff delay estimates for our protocol prove to be less than that for other protocols in this study, even with route optimization. We further propose an extension to Mobile IP to support our protocol with minimal modification.
