网络控制系统Web服务器服务质量管理方案的研究

提出一种基于Web的自适应内容传输管理方案，为不同网络客户提供不同优先级的性能服务，并且各种服务相互独立，同时能基于请求率和传输带宽共享系统资源。这种方案在传统的允入控制基础上改善了服务性能，根据网络负载情况和服务质量需求自适应选择传输内容，满足了客户对网络传输服务质量需求。该管理方案可以在三层模型的中间层实施，便于修改和维护，给出的实验结果显示了该方案的有效性。

Research on network control system Web server QoS management solution

This paper presents a new approach to Web server resource management solution based on Web content adaptation.This method can provide architecture for performance differentiation among classes of clients,performance isolation among independence services,and capacity sharing on request rate and delivered bandwidth.This approach subsumes traditional admission control technicians and enhances server performance by selectively adapting content in accordance with both load conditions and QoS requirements.This management solution can be implemented in middle-ware of three layer model which is ease to be modified.At last the experiment data illustrates the validation of this approach.
