open-source network simulation tools that run on Linux or BSD systems
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
GNS3 can be used to simulate a network composed exclusively of open-source routers, switches, servers, and hosts. In this post, we will investigate how well GNS3 works when we use it strictly as an open-source network simulator, without using Cisco or Juniper routers in the simulation.
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
