For the load balancing problem of cluster system,an improved dynamic load balancing strategy based on feedback is introduced.Combined with periodic feedback theory,the strategy divides update interval into several equal subintervals,and adopts a random mechanism to distribute requests in each subinterval.The model of the process of cluster system is founded based on queuing theory and the formula for calculating the system performance is obtained.Simulation results show that,compared with Aggressive LI strategy,this strategy can attain equivalent performance at the expense of smaller cost,and has small complexity of implementation.
