VIRTUAL DEVICE COLOCATION DETERMINATION USING RAW SIGNAL DISTANCE MEASUREMENTS

A device determines whether virtual resources are co-located on a physical resource. The determination is performed by aggregating a plurality of timestamps into a data structure, each timestamp of the plurality of timestamps corresponding to one of a sent time or a receive time of a network packet exchanged between two of the virtual resources, the data structure representing one or more raw signals of distance between sets of the virtual resources that exchanged network packets, the virtual resources synchronized to a common reference clock. The device determines, using the data structure, subsets of sets of virtual resources that are using shared physical hardware. The device outputs indicia of the subsets.
