In this tutorial, we demonstrate basic software-defined networking (SDN) concepts using the POX SDN controller, POX components, and the Mininet network simulator. We will show how to use the POX SDN controller to update flow tables on the SDN switches in a simulated network so every host on the network can forward packets to another […]
The Mininet network simulator includes MiniEdit, a simple GUI editor for Mininet. MiniEdit is an experimental tool created to demonstrate how Mininet can be extended. To show how to use MiniEdit to create and run network simulations, we will work through a tutorial that demonstrates how to use MiniEdit to build a network, configure network
To install the Mininet SDN network simulator on a remote server running on Amazon’s EC2 cloud, follow the procedure shown below. After installing it, I did some basic tests and it seems that Mininet works well on the Amazon EC2 server.
I recently configured an Amazon EC2 instance so that I could run the XFCE desktop environment on it and control it from my local laptop computer using SSH and VNC. But what if I want to use my iPad to do control the remote Amazon EC2 server? I want to experiment with complex network simulations
Having set up an Ubuntu Linux server running on a free micro-instance in Amazon’s Web Services EC2 service, I’d like to see how some of the open-source network simulation tools I’ve been using work in the cloud. First, I will install the CORE Network Emulator on my Amazon AWS EC2 virtual private server. Please read
In a previous post, I showed how easy it is to set up a remote server on Amazon’s AWS service. Now I would like see if I can run one or more of the open-source network simulators I’ve been using on this remote server. I want be able to access a network simulator from any
I recently set up a free Amazon AWS server. As I experimented with it, I installed a GUI desktop. Then I encountered some issues that I eventually resolved by creating a new user with its own password and then using that user for the rest of my activities. For my own reference, and in the
As an incentive to use their service, Amazon Web Services offers new users a “free tier” of service that provides a VPS “micro-instance” at no cost for one year. The free tier of service is fairly flexible. Amazon AWS provides enough free hours to run the micro-instance twenty-four hours a day for a year but,
After installing the Mininet software-defined network simulator on a virtual machine, you may want to build the documentation. Documentation is available on the Mininet web site but, if you installed a beta version of a new development release or installed an old version, you may want to use the documentation specific for the version you
Most people who use the Mininet network simulator will download and set up the Mininet virtual machine image. However, there are times when we may want to use a different version of Mininet than the one already installed in the Mininet VM. For example, we may want to use the newest features of Mininet currently
When setting up a complex network scenario in the CORE Network Emulator, we may want to change the default configurations provided by CORE services. Fortunately, the CORE Network Emulator allows the user to customize services. A user may want to customize CORE services in order to: set up complex network emulation scenarios by adding more
CORE Services is a feature of the CORE Network Emulator — an open-source network simulator — that configures and starts processes on each node running in a network simulation. Examples of processes supported by CORE Services are: quagga, dhcpd, or radvd. Because the CORE Network Emulator implements its virtual nodes using a lightweight virtualization technology
