Abstract
A system and method for correcting clock discrepancy in simultaneous network traffic data captures in a multi-tiered, multi-session environment. The invention uses intrinsic constraints imposed by the nature of the traffic onto the possible temporal sequence of the packets, The invention uses the intrinsic restraints of the network architecture and the protocols used at each segment along with the time stamps in the various segments to determine both an offset and scale correction to the clock readings (timestamps) in the traces in order to obtain a correct temporal sequence of packets when using multiple capture agents/engines/network monitors.
