【摘要】 已经提出的快速和平滑切换框架中,普遍使用接入路由器进行信令的处理和数据的缓存,这种结构不易部署和扩展。本文提出了利用链路层与网络层之间的归属信息进行预测切换的协议,描述了预测切换协议的切换过程,阐述了归属信息的组织和使用方法,分析了切换协议的时延特性,并进行了实验验证。该协议通过对本地管理单元和域管理单元的使用,能够有效减少切换时延和丢包,并具有易部署和易扩展的能力。更多还原

【Abstract】 Most released frameworks of fast handovers and smooth handovers use access routers to adapt signals and buffer packets. Therefor,it is difficult to implement and expand in real networks. An anticipated protocol was proposed by using the attached information between data link layer and network layer in the paper. The handover process of the anticipated protocol was described, the organization and usage of the anticipated protocol were discussed, the delay character of the anticipated protocol was analyzed and the experiment was operated. By using local and domain management units, the anticipated protocol can reduce handover delay, solve packet loss, and has capable of implementation and expansion.更多还原
