Technologies are provided for preventing abuse of software-defined datacenter networks. In some examples, an SDN abuse prevention module within a control layer of an SDN may use graph analysis rules and monitor network paths over time to detect and prevent abusive network conformation change command series. Instance-generated network paths may be analyzed to determine if the paths attempt to repeatedly traverse one or more sensitive network paths. If so, the paths may be implemented or denied based on, among other things, the time scale within which they attempt to repeatedly traverse the sensitive network paths.
