Abstract

Various embodiments provide methods, devices, and non-transitory processor-readable storage media enabling network probing with a communication device based on the communication device sending a probe via a first network connection and receiving the probe via a second network connection. By leveraging a capability of a communication device to establish two network connections at the same time, various embodiments may enable a single communication device to act as both a probing client and a probing server. In this manner, various embodiments may enable standalone network probing, i.e., network probing that may not require a remote dedicated probing server to act as a probe generator or a probe sink.
