摘要
移动用户对实时业务(语音、视频业务)的需求引发了对移动IPv6环境下服务质量问题的研究.针对移动IPv6实时业务的QoS特性,提出了一种可缩放的服务质量架构———非集中层次化移动IPv6管理QoS架构,定义了该架构中的基本元素、架构的部署及其在实际使用中的交互,并利用比较分析和仿真的方法验证了该架构的可行性、可扩展性、切换延迟及传输延时小等优越性.
The demand of real time service such as voice and video applications in mobile IPv6 requires new solutions to the problems of Quality of Service. To provide end-to-end, flow based QoS in a mobile environment, there must be a proper deployable QoS architecture. A scalable De-Centralized Hierarchical Mobility IPv6 Managed QoS Architecture is proposed. The basic elements, the deployment of the architecture, and the concrete interaction in applications are described. The analysis and the simulation results showed the feasibility of the architecture and its advantages such as higher extensible ability, smaller handover delay and data transfer delay.
