Dynamic Load-balance Scheduling Approach in Linux Based on Real-time Modifying LVS Weight
Yihua Liao, Min Lin · Advances in engineering research/Advances in Engineering Research · 2017
Linux Virtual Server (LVS) cluster technology is widely applied at high-performance web service.In LVS, Weighted Least-Connection (WLC) scheduling algorithm is usually adopted due to its good effect.However, WLC scheduling algorithm can't always make real server (RS) run efficiently.In order to improve RS usage and make RS in health load, we proposed a dynamic load balance scheduling approach (DLSA) which dynamically modifies the weight of RS by the feedback information from RS. Experimental results show that DLSA can make full use of RS in LVS.
