Descriptions of open source networking software for Linux or BSD systems: configuration, operation, maintenance
GNS3 is a very popular network simulation tool that runs on the major operating systems: Windows, Mac OS, and Linux. GNS3 is primarily used to emulate networks of Cisco routers and is used by professionals studying for Cisco certification exams. GNS3 supports Cisco router software images running on the Dynamips hardware emulation program. GNS3 also […]
Virtual Networks over Linux (VNX) is an open-source network simulation tool that builds and modifies virtual network test beds automatically from a user-created network description file. In its current version, VNX supports several different virtualization methods: KVM, user-mode linux, and DynaMIPS. VNX was developed by the Telecommunication and Internet Networks and Services (RSTI) research group
In this post, I describe the procedure I followed to install the VNX Network Simulator on a computer running the Ubuntu Linux 13.10 operating system. The VNX system consists of the VNX program that parses the scenario description XML file and builds and manages the virtual network elements; XML files that contain a description of
The Mininet open-source network simulator is designed to support research and education in the field of Software Defined Networking systems. Mininet creates a simulated network that runs real software on the components of the network so it can be used to interactively test networking software. Software Defined Networking (SDN) is a relatively new technology, but
The easiest way to get started using the Mininet network simulator is to use the Mininet virtual machine. It is based on the Ubuntu Linux Server operating system and comes with all the software and tools required to support Mininet already installed. The Mininet web site provides detailed setup notes, describing how to download and use the
Marionnet is an open-source network simulator that creates a network composed of Linux virtual machines. A group of educators at the Université Paris 13 created Marionnet so they could use it as an educational tool. Marionnet allows students to build and configure networks, and save their configurations for future use. It also allows teachers to
I’ve been using Parallels Desktop for Mac to run a Debian Linux 6.0 virtual machine. I wanted to install the Parallels Tools in the Debian virtual machine so I could take advantage of better integration between the Linux virtual machine and the Mac OS X host computer. It wasn’t as straightforward as I thought it
The Marionnet network simulator is easy to install but there are some specific system configurations that must be changed so that all the features of Marionnet work well. This post will describe the installation procedure for the Marionnet open-source network simulator on Debian Linux 6.0.
The Integrated Multiprotocol Network Emulator/Simulator (IMUNES) is a fast, functional network simulator that runs on the FreeBSD operating system. It was created by a team of researchers and educators at the University of Zagreb. The IMUNES development team offers a VirtualBox image of a FreeBSD system with IMUNES installed so it is easy to evaluate.
The Cloonix development team recently released Cloonix version 21. The new version includes some significant improvements, such as support for Cisco software images (via Dynamips) and support for 32-bit architectures. The Cloonix developers also added a large library of prepared filesystems including new, lightweight versions of popular linux filesystems, such as debian, ubuntu and fedora,
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
