WMQ: Towards A Fine-grained QoS Control for E-Business Servers

As the Internet increases explosively, the QoS support in e-business server is becoming more and more important. However, the implementation of a fine-grained QoS control model in the e-business servers is a challenging task. In this paper, we propose a WorkManager-based QoS scheduling framework (WMQ) for e-business servers. This framework hides the complexity of QoS scheme implementations and provides a flexible architecture supporting fine-grained QoS control. A prototype of our framework has been implemented within the open-source server Tomcat. The evaluation of this prototype shows that our approach allows Tomcat to effectively meet the QoS requirement of the applications by fine-grained QoS control. Our experience also shows that the WMQ framework can efficiently simplify and reduce the implementation effort involved in developing QoS-enabled e-business servers.
