It uses the kernel-level network stack virtualization technology provided by FreeBSD.
IMUNES runs on both the FreeBSD and Linux operating systems.
Please click here to see my posts about GNS3.Ī team of researchers at the University of Zagreb developed the Integrated Multi-protocol Network Emulator/Simulator (IMUNES) for use as a network research tool. GNS3 provides a variety of prepared open-source virtual appliances, and users can create their own. GNS3 can also be used to simulate a network composed exclusively of VirtualBox and/or Qemu virtual machines running open-source software. GNS3 has a large user base, made up mostly of people studying for Cisco exams, and there is a lot of information freely available on the web about using GNS3 to simulate Cisco equipment. GNS3 is a graphical network simulator focused mostly on supporting Cisco and Juniper software. Please click here to see my posts about the CORE Network Emulator. CORE is a fork of the IMUNES network simulator, and it adds some new functionality compared to IMUNES. CORE supports the simulation of fixed and mobile networks.ĬORE will run on Linux and on FreeBSD. This allows CORE to start up a large number of virtual machines quickly. The Common Open Research Emulator (CORE) provides a GUI interface and uses the Network Namespaces functionality in Linux Containers (LXC) as a virtualization technology.

Gns3 network simulation update#
Cloonix has an active development team, who update the tool every two or three months and who are very responsive to user input. Cloonix provides a wide variety of pre-built filesystems that can be used as virtual machines and provides simple instructions for creating other virtual machine root filesystems. Cloonix uses QEMU/KVM to create virtual machines. The Cloonix network simulator provides a relatively easy-to-use graphical user interface. Please post a comment on this page to let me know about any other open-source network simulation tools I did not include in this list. This is a list of open-source network simulators and network emulators that run on Linux or BSD.
