Abstract
This paper discusses architectural performance of virtual operating switches, and systems under various topological structures to handle packet deliveries of large streaming and dynamic data sets. The topology structures studied include: tree, fully connected mesh, and star. A virtual network framework is developed that can generate any number of nodes with reconfigurable parameters. An evaluation on memory requirements, disk-space, and CPU usage on three different virtual network switches (openvSwitch, openSwitch, openWRT) were also investigated. Two specific protocols–Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) are tested against bandwidth requirements.
Highlights
When creating a large test network, a physical system would be the most ideal in that it would more closely mimic a real life structure
Two hypervisors were used in this paper, Oracle virtual machines (VM) VirtualBox and VMware vSphere ESXi
Oracle VM VirtualBox, referred to as just VirtualBox, is an open source and free to use hypervisor that is supported on a number of different operating systems as well as containing support for the virtual machines to be tested
Summary
When creating a large test network, a physical system would be the most ideal in that it would more closely mimic a real life structure. Two hypervisors were used in this paper, Oracle VM VirtualBox and VMware vSphere ESXi. Oracle VM VirtualBox, referred to as just VirtualBox, is an open source and free to use hypervisor that is supported on a number of different operating systems as well as containing support for the virtual machines to be tested. Three virtual switch OS‟s were used: Open vSwitch, OpenSwitch and OpenWRT These operating systems were chosen due to being open source, free to use, and their large market share. An open source allows a user to modify and compile the operating system to their desire This can become useful for removing unneeded applications and other files to reduce space. Each can be installed directly on a physical commercial router or network switch Each runs their own modified version of Linux that is tailored with different applications to reach the same goals. The largest contributors to the hardware specifications are the file size and memory requirements
