Enhanced Dynamic Load Balancing Algorithm in Computer Networks with Quality of Services

Abstract

Nowadays there is an increase in transfer volumes of audio, video and other types of multimedia content in modern computer networks (CN). Multimedia streaming and multicasting applications have limited jitter and end-to-end delay requirements and do not allow full providing of all necessary conditions for efficient data transmission on the Internet. To provide quality of service (QoS) of streaming applications Internet Engineering Task Force (IETF) proposed two QoS architectures: IntServ and DiffServ. However, these architectures have the limited ability of dynamical change in the movement of data flows and do not ensure compliance with all QoS requirements. Complexity in service of CN is often combined with incomplete compatibility of network decisions that involves dependence on the hardware manufacturers. The purpose of the work is the development of the enhanced dynamic load balancing algorithm in CN with QoS. The present work is dedicated to the simulation of software of dynamic load balancing processes. The results of the investigations of the offered algorithm on different topology of CN by 5 QoS-metrics are presented too. The assessment and comparison of the efficiency of the offered load-balancing algorithm with known analog such as Yen’s algorithm including traffic engineering (TE) module are executed.
