Performance analysis of network virtualization in cloud computing infrastructures on OpenStack

Abstract

Cloud computing has become popular in IT technology because of advantages that focus on flexible, scaling, resources and services which help customers easy to build their own on-demand IT system. Cloud computing also has ability to balance, share, and manage IT resources between customers to get better performance. OpenStack, a new open source cloud computing framework which was a built-in modular architecture and focus on IaaS. OpenStack also focuses on NaaS by using network virtualization technology and OpenStack has been used popular in business. This paper does a research on network performance on OpenStack network module code name Neutron. The parameter related to network performance such as throughput, package loss, time and delay of data transmission are estimated through UDP protocol. Our research investigated the possible internal traffic flow pattern and evaluated network performance of each pattern on OpenStack cloud computing environment.
