Abstract
While content-aware QoS is increasingly desired for cluster-based Web systems, the high processing overhead it caused can easily make the Web switch a system bottleneck. In this paper, we present a more scalable architecture in which content-aware request distribution and service differentiation can be performed on the back-end server nodes. Based on this scalable architecture, a kernel content-aware QoS mechanism is proposed for Web clusters. Simulation results demonstrate that this kernel content-aware QoS mechanism can provide guaranteed performance for preferred clients even when the server is subjected to a client request rate that is several times greater than the server’s maximum processing rate.
