Project Information
The Topology Management Tool (ToMaTo) is a topology-centric network testbed. ToMaTo has been developed in the context of the German-Lab research project which has been funded by the German Ministry of Education and Research (BMBF).
Currently the testbed is run by the ToMaTo consortium and academic institutions can join it for free if they contribute resources. Thus ToMaTo continuously grows and already spans across multiple continents.

Main Features
Intuitive editor
Create your virtual network topology in an intuitive web-based editor. No need to write config files or code.
Up and running in seconds
Even very complex topologies can be configured and started in a few seconds.
Sites worldwide
Create topologies that go around the globe, select freely from our various sites.
Packet capturing
Have a look at what goes over the wire. Just activate packet capturing on a link and analyze the traffic in Wireshark.
Link emulation
Configure different properties like latency, packet loss or bandwidth on each link.
Graphical console
Control your virtual machines directly from a web-based console viewer. Watch your VM boot or control graphical user interfaces.
Virtual networks
Use virtual switches or external networks to connect your topology.
Different virtualization technologies
Select from full virtualization (KVM) and container virtualization (OpenVZ) for each topology component to save resources.
Pre-configured templates
Select from a wide range of pre-configures VM images spanning from Debian, Ubuntu and other Linux systems to Windows XP.
Integrated monitoring
Observe the resource usage of a whole topology or individual components.
