    摘要: A method includes receiving a first capture time corresponding to a first time that a data packet is received at a first probe and a second capture time corresponding to a second time that the data packet is received at a second probe. The data packet is from existing network traffic transmitted over a data network. The first and second probes can be configured to capture the data packet in response to a capture instruction. The first capture time and second capture time are different and are used to calculate the latency of at least a portion of a data network.
