Mixed control method of Web QoS based on threshold of balance status
HU Debi · Computer Engineering and Applications Journal · 2013
On the basis of web-server control clusters with QoS, based on L4/L7 switching, a mixed load balance strategy is designed, which takes into account content of request, server performance and overall equilibrium state of the cluster load. Algorithm introduces a feedback loop which dynamically adjusts the weights of servers, by choosing different strategy according to thresholds of load balance, the performance of the Web cluster system is promoted.
