A topography contains the list of needed PCs for the experiment, which software images are needed, and how the PCs are networked. Topographies are best created using our Network GUI tool. A basic topography for testing a firewall could look like this: Firewall topography
where PC0 would be an "external" host, PC1 would be the firewall, and PC2 would be an "internal" host. Topographies are uploaded to ReAssure as XML files.
