A Mobile Cache and the Evaluation Method for MIPv6 Smooth Handovers
一种用于MIPv6平滑切换的移动缓存和评价方法

A well-known structure has been used for Mobile IPv6 smooth Handovers in most released frameworks. As the management of mobility signals, the caching and forwarding of pre-path packets are all operated by access routers, the structure is hard to deploy and implement in real networks. In this paper, a mobile cache was proposed for Mobile IPv6 smooth handovers. The time sequence of buffer-forwarding process was analyzed. An evaluation method was formulized with the packet loss rate and the packet out-of-order rate. In simulation, the evaluation method was analyzed and validated. The mobile cache can optimize the structure of smooth handovers, and the evaluation method can enhance the performance of buffer-forwarding processes.
