移动IPv6为IPv6节点提供了在Internet不同子网中使用不变的家乡地址进行漫游通信的能力。相比于传统固定网络,节点的移动为通信的服务质量(QoS)保证提出了新的挑战。介绍了当前的移动IPv6技术和IP网的QoS技术,并针对移动IPv6的特点阐述了其QoS机制,对比各种机制的特点,对其进行网络时延的分析。最后说明了移动IPv6的QoS需要解决的问题。
Mobile IPv6 provides IPv6 nodes the ability to roam at home addresses that use the same home address on different subnets of the Internet. Compared with the traditional fixed network, the movement of nodes poses new challenges for the quality of service (QoS) of communication. The current technologies of Mobile IPv6 and QoS of IP network are introduced. The QoS mechanism of Mobile IPv6 is expounded. Compared with the features of various mechanisms, the network delay is analyzed. Finally, the problem of mobile IPv6 QoS needs to be solved.
