Patent ID: 8259757

Claim:
A method for analysis of a synchronized data traffic of a packet and address-oriented data network, comprising: a plurality of data generating and/or data-receiving network participants, respectively with individual network addresses or other individual identification features, wherein the data network synchronizes received data packets and known transmission and processing times using receipt points in time, and data transmissions ensue synchronized with the data traffic, said method comprising: in mirror memory in at least one network participant, recording data packets that said at least one network participant has sent via the data network in parallel with the data transmission and/or data packets that said at least one network participant has received in parallel with an internal data processing; upon an occurrence of a trigger event in at least one of the active network participants, in each of the network participants equipped with a mirror memory, freezing the mirror memory of that network participant to cause each mirror memory to contain data of the same time segment for respective different points of the data network; and providing all data frozen in the respective mirror memories via the data network for evaluation while the synchronized data traffic remains unaffected.
