摘要:

提出了基于多协议标记交换(MPLS)的端到端自适应移动IP(MIP)快速切换技术,旨在提高基于MPLS移动IP的灵活性与可扩展性. 基于运营网络的层次化结构,通过在标记交换路由器(LSR)中添加与更新移动节点(MN)列表,以分布实施的方式动态优化区域外地代理(RFA)的部署. 理论分析表明,该技术具有对上层应用和底层网络服务透明、节省开销、部署灵活、向后兼容等优点.

Abstract:

An end to end adaptive multi-protocol label switching (MPLS)based fast handover method for mobile IP(MIP) was proposed to improve the flexibility and scalability of MIP over MPLS. The new method was based on the hierarchical structure of network in operation. Through installing and timely refreshing a mobile node(MN) list in each label switched router (LSR),the deployment of regional foreign agent (RFA) could be optimised dynamically in a distributed way. Theoretical analysis demonstrates that the new method is transparent to the upper layer applications and underlying network services, backward compatible, easy to deploy and cost effective.

Key words: mobile IP, fast handover, multi-protocol label swiTching
