Study of enterprise load balancing algorithms using model-based design

Abstract

Given work describes load balancing algorithms for external services with unspecified clients used in real enterprise facilities. Simplest example of such service is a pair of a web server and a browser. Principles of load balancing, their pros and cons are considered, their implementation and applicability to different services are described. Algorithms of load balancing for DNS Round Robin, Direct Routing, Redirect methods are studied. Result of model implementation for cluster system allowed to obtain estimations of oscillation effect decrease between its overloaded and normal states. As a conclusion recommendations for using implemented model of queuing network for different enterprise services of user request processing are given.
