The Generalized Precision Time Protocol (gPTP) synchronizes timekeeping across a network so that requirements for time-sensitive applications can be met. It includes the maintenance of synchronized time during normal operation and following the addition, removal, or failure of a network component. The gPTP Test Suite is a Defensics test suite designed for testing the robustness of gPTP instances by sending them invalid, incorrect, and malformed data. These anomalies can reveal bugs and other unintended behavior in tested implementations. Discovered faults can then be analyzed and remedied by the developers.
