A Study of Algorithm Replacement Mechanism for Environment Adaptive Load Balancer

摘要

Recently the use of computing technologies for distribution systems such as cloud or grid is increasing for effective management of IT operation and investment cost reduction. One of the important tasks in distributed systems is to prevent the server from overloading. Although a load balancer has been introduced to solve this problem, there is a limitation that an existing load balancer must use only one initially set algorithm. To solve these limitations, this paper proposes a load balancing method that dynamically replaces the load balancer algorithm according to the server status and environment. The proposed method is that the load balancer collects the server status information in real time, analyzes the result of the server status, and replaces it with an appropriate algorithm if necessary. We experimented with several algorithms and proved that this proposed load balancing is more effective than the existing load balancing.
