摘　　要：基于位置和标识分离的解决方案不能很好地同时解决移动性支持和可扩展性差的问题,并且难于部署。文章提出一种新的基于位置和标识分离的网络架构,并给出与该架构相适应的移动性管理解决方案。该方案不仅能很好地解决网络的可扩展性问题,在移动性支持方面还具有如下的特点:不需要修改终端协议栈,易于部署;标识符含有一定的路由信息,能提供较好的与传统终端互通的能力;将映射系统分布于边缘网络内,增强了系统的鲁棒性并降低了切换时延。Solutions based on ID/Locator separation are not easily deployed and cannot be used to resolve routing scalability and mobility problems simultaneously. This paper proposes a novel network architecture based on the idea of ID/Locator separation but which has a mobility management mechanism built on top of the architecture. In the proposed mobility management mechanism the protocol stack of the mobile hosts does not need modifying, so the solution is easily deployed. The IDs contain some routing information that provides intrinsic interworking capabilities with traditional mobile nodes. The mapping system is also distributed to the edge networks, increasing the robustness of the whole system and decreasing handoff delay.
