Abstract: In one embodiment, a process observes a communication network with automated systems for packet relative arrival times between a pair of devices having stable or periodic communications within the communication network. The process performs a spectral analysis on the packet relative arrival times between the pair of devices to determine a periodicity of communications between the pair of devices. When a change in the periodicity of communications between the pair of devices is detected based on continued inference observing, the process may then mitigate the change in the periodicity of communications between the pair of devices.
