Abstract (en)
[origin: WO2014090612A1] A method for synchronizing data packets from an unclocked data communication network (14) with a clocked data communication network (12) comprises the steps: receiving clocked data packets (72) from the clocked data communication network (12) in a gateway (28) at clock cycles (70) of the clocked data communication network (12); packing data from the clocked data packets (72) into first unclocked data packets (74) for the unclocked data communication network (14) in the gateway (28); providing the unclocked data packets (74) with one time stamp each, from which a clock cycle of a clocked data packet (72), the data of which have been packed into a respective first unclocked data packet (74), can be reconstructed; transmitting the first unclocked data packets (74) via the unclocked data communication network (14) to a receiver node (24) of the unclocked data communication network (14); reading the time stamps out of the first unclocked data packets (74) and reconstructing the clock cycle (80) of the clocked data communication network (12) from the time stamps, a transmission frequency, a number of clocked data packets and/or a local clock in the receiver node (24); and transmitting second unclocked data packets in a clock cycle (84) which is synchronous with the reconstructed clock cycle (84).
