Abstract: The dynamic load balancing algorithm based on the monitoring server load, self-similar characteristics of passing traffic have to provide a statistically uniform load distribution on servers, high performance, fault tolerance and capacity, low response time, the amount of overhead and losses was propose in work. Integrated measurement for the total imbalance level of the system were entered. Described in this paper load balancing system built on the basis of subsystem load balancer and subsystem control and monitoring that closely interact with each other. On the basis of the developed load balancing system is provided a dinamic algorithm of multifractal load balancing. Dynamic load balancing algorithm is based on the monitoring server load, the characteristics of self-similar traffic and turned to providing a statistically uniform distribution of the load on servers, high performance, fault tolerance and capacity, low response time, the quantity of service information and losses. In the developed algorithm data redundancy is reduced by dynamically changing the frequency intervals of control that adapts to the structure of incoming traffic given its self-similar structure. In this algorithm, the number of classes of flows depends on resource requirements. Also metrics are introduced for the each server and total imbalance level of the system. In the further work is necessary to simulate this algorithm in a distributed system and experimental study of the effectiveness of the proposed algorithm in comparison with the existing by changing the parameters of the incoming traffic.
