We tool a first look at the Common Open Research Emulator (CORE) in a previous post. We used the VCORE virtual appliance that we downloaded from the CORE web site to evaluate CORE but we found some issues with missing software. Now, we will install CORE on an Ubuntu Linux system as the first step […]
The Common Open Research Emulator (CORE) is an open-source network simulator developed by Boeing’s Research and Technology division and supported, in part, by the US Naval Research Laboratory. It is a fork of the IMUNES Network Emulator project and it was developed as a tool to support a mobile data networking research project. It can
The Netkit open-source network simulator was created by a group of university professors who use it as a tool in their teaching. They created a large number of pre-configured lab scenarios, each with lecture slides that describe the scenario and the technology used in the scenario, and make these assets available on the Netkit web
We will install the Netkit open-source network simulator on an Ubuntu Linux 12.04 system that is installed on a virtual machine on my iMac. As I’ve mentioned before, running Linux in a virtual machine on a Windows or a Mac is a convenient way to experiment with different Linux systems and software. Netkit, because it
We will install the Cloonix open-source network simulator on a Knoppix Live USB drive. Knoppix is a version of Linux that is designed to boot from a CD, DVD, or USB drive. It can run on almost any computer hardware and it runs in memory, so it does not affect the hard drive of computer
I used the Cloonix open-source network simulator to simulate a very simple network. This helped me understand how to use the “point and click” functionality provided by the graph function to manually build and configure a test network. I also hope that the following procedure would be useful as a simple tutorial for anyone interested
For a while now, I’ve been trying to get the Cloonix open-source network simulator working on a computer running the Knoppix Linux distribution. I wanted to run everything on a USB Flash stick that could be attached to any computer and to create a portable version of Cloonix. Since I cannot yet run Cloonix in
This article describes my first experience with the cloonix open-source network simulator. I installed cloonix on ubuntu 12.04 and tested it by running the demonstration script provided with the cloonix package. The demonstration script sets up a simulated OSPF network and runs HTTP traffic between two virtual computers attached to that network. The cloonix package
A network of virtual machines can be used for practical testing and research. Sandia National Laboratories recently announced that they have created a virtual network of three hundred thousand virtual machines, each of which is running the Android operating system, on a single large supercomputer. In the recent past the researchers at Sandia National Laboratories
