Abstract

The majority research related to cloud computing infrastructure has focused on the communication between Virtual Machines (VMs) in a cloud platform. Which neglected the possible performance difference caused by virtual network function used in the communication between VMs. The virtual network function such as virtual router (VR) tends to introduce overhead on network performance. Besides, another trending part of today’s data-centers are the software basedVirtual switches called OpenVirtual Switches (OVS) which are capable of forwarding traffics between VMs and the physical network. Similarly, there is also VXLAN implemetation that uses linux bridge which can refer as Native VXLAN. This project is to investigate the performance difference of OVS and Native VXLAN by benchmark and compare the performances of OVS and Native implementations in a VXLAN network with different type of use cases using an Open Source based cloud management platform.
