Abstract: In one embodiment, data packets are captured from a network using a physical, network-connectable data capture probe. As the data packets are captured, the data packets are time-stamped with time-of-capture time-stamps. The time-stamped data packets are then stored; and in parallel, the time-stamped data packets are forwarded to at least one consumer in real-time.
