随着网络技术的不断发展,特别是无线环境和移动设备的引入,更多的具有不同的QoS需求的业务也将在网上得以实施,这使得传统的网络级QoS保证将不能满足用户的QoS需求,自适应QoS是在应用级解决未来无线移动网络环境下用户质量需求的较好方法。文章针对未来网络所具有的网络异质性、用户移动性、多链路覆盖、多服务覆盖等特点,提出了一个对等结构的自适应QoS模型框架,首先分析了自适应QoS基本结构、研究内容、系统特征、环境特征等,然后提出了系统的基本功能结构,并对其进行了详细讨论,最后提出了进一步研究工作的方向。
With the continuous development of network technology, especially the introduction of wireless environment and mobile devices, more services with different QoS requirements will also be implemented on the Internet, which makes the traditional network-level QoS guarantee will not meet the QoS requirements of users , Adaptive QoS is a good way to solve user quality requirements in the future wireless mobile network environment in the application level. Aiming at the characteristics of network heterogeneity, user mobility, multi-link coverage and multi-service coverage in the future, this paper proposes a peer-to-peer QoS model framework. Firstly, the basic structure of adaptive QoS is analyzed. Content, system characteristic, environment characteristic and so on, and then put forward the basic functional structure of the system, discussed it in detail, and finally proposed the direction of further research.
