Antidote is the network emulator that runs the labs on the Network Reliability Labs web site. You may install a standalone version of Antidote on your personal computer using the Vagrant virtual environment provisioning tool. In this post, I show you how to run Antidote on a Linux system with KVM, instead of VirtualBox, on […]
Antidote is a network emulator combined with a presentation framework. It was designed to create and deliver networking technology training. Its user interface operates in a web browser, including the terminals that students use to run commands on emulated network devices and servers. Antidote is the engine that runs the Network Reliability Labs web site.
Vrnetlab, or VR Network Lab, is an open-source network emulator that runs virtual routers using KVM and Docker. Software developers and network engineers use vrnetlab, along with continuous-integration processes, for testing network provisioning changes in a virtual network. Researchers and engineers may also use the vrnetlab command line interface to create and modify network emulation
In this post, I demonstrate how to create a network emulation scenario using Libvirt, the Qemu/KVM hypervisor, and Linux bridges to create and manage interconnected virtual machines on a host system. As I do so, I will share what I have learned about network virtualization on a Linux system. Libvirt provides a command-line interface that
Packet is a hardware-as-a-service vendor that provides dedicated servers on demand at very low cost. For me and my readers, Packet offers a solution to the problem of using cloud services to run complex network emulation scenarios that require hardware-level support for virtualization. Packet users may access powerful servers that empower them to perform activities
The Cloonix development team recently released a major update to the Cloonix network simulator. Cloonix version 28 makes major changes to the infrastructure of Cloonix. It changes the installation procedure, the location of Cloonix files on your computer, and the names of the commands used to start and administer Cloonix. Cloonix version 28 also makes
I need to determine the maximum number of KVM virtual machines that can run on an average laptop computer. Unfortunately, I cannot find authoritative information about the maximum number of KVM virtual machines that can run on a host computer. Most information I could find about KVM limits does not publish absolute limits but, instead,
In this post, I will show how to set up data capture in the GNS3 network simulator when using network devices that are emulated by VirtualBox or QEMU virtual machines. The GNS3 network simulator makes it easy for users to capture and view data passing across the interfaces of devices running in a GNS3 network
Open-source DevOps tools are used to deploy applications and services in datacenter server networks, but they may also enable researchers or students to simulate networks. In this post, we will survey popular open-source DevOps tools and provide links to information that shows how to use them to create network simulation scenarios. Most open-source network simulators
