一个具有自适应QoS的对等系统结构框架

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。

A Peer-to-peer Adaptive QoS Architecture

With the development of Internet technology,especially the conditions of wireless and mobility be migrated, more user's tasks with different QoS requirement will be implemented in Internet, this will make current network-level QoS guarantee not meeting future user's needs.However,adaptive QoS is the best way that solves future user's quality needs in wireless mobile environments.In this paper,for the future network conditions with heterogeneity,mobility,more covered links,more covered services and so on,it proposes an adaptive QoS framework for peer-to-peer architecture. Firstly,this paper analyzes the basic architecture,studying contents,system characteristics,and environment characteristic of adaptive QoS.Then it proposes a basic function framework and details it.Finally, it shows the future work direction.
