摘要： 提出了一种新的框架结构以支持不同网络条件下服务质量（QoS）的动态配置及调整，同时提出了一种新的QoS参数化机制来支持网络环境的变化，并且通过编程接口（API）详细描述了这种QoS适应性机制，最后以BSD网络操作系统为例介绍了该方案的关键技术。

Abstract: This paper presents a new mechanism based on QoS(quality of service)parameterization to support adaptation for upper application to change in the network environments. It also provides an API(application progrm interface) for supporting QoS adaptation and introduces the framework to support QoS configure over different networks. Finally it describes extensions to BSD Unix which allows appication to monitor the underlying system's QoS and adapt to changes in QoS.
