PMIPv6区域位置管理的动态QoS预留优化方案

Dynamic QoS Reservation Optimization Scheme Based on Region Location Management in PMIPv6

MIPv6的扩展协议PMIPv6是当下研究的热点,PMIPv6让移动节点有效摆脱了参与移动性管理的束缚,从而提高了移动IPv6的移动性能。良好的QoS是网络传输质量的基础,其中QoS预留方案为数据流提供了端到端的服务质量保障。本文将PMIPv6协议与QoS预留方案结合,提出了一种新的针对PMIPv6的QoS预留优化方案,将管理域间的信令开销限制到管理域内范围,大大减少了信令开销。

PMIPv6 is a research hotspot at present.PMIPv6 enables mobile nodes to get rid of the constraint of participating in mobility management effectively,thus improves the mobile performance of mobile IPv6.Good QoS is the basis of network transmission quality,among which QoS reservation scheme provides end-to-end service quality assurance for data flow.In this paper,PMIPv6 protocol is combined with QoS reservation scheme,and a new QoS reservation optimization scheme for PMIPv6 is proposed,which limits the signaling overhead between management domains to the domain scope and greatly reduces the signaling overhead.
