Abstract
Time information which is to be transmitted via a data packet network is called up from a time information source and is transmitted to a data packet transmission module. The data packet transmission module controls the transmission time of a data packet in which the time information is transmitted via the data packet network. The transmission time and the calling of the time information are aligned with respect to one another in time by a transmission signal which is generated by the time information source or by the data packet transmission module and indicates the transmission time.
Claims17
A method for transmitting time information via a data packet network, comprising:
- calling time information from a time information source;
- sending the time information to a data packet transmission module which times transmission of data packets;
- transmitting the time information from a first communications device to a second communications device via a data packet;
- using a transmission signal to coordinate transmission of the data packet and calling of the time information with respect to one another, the transmission signal indicating the time of transmission;
- and
- generating a reception signal when a data packet receiving module at the second communications device receives the data packet transmitted via the data packet network, the reception signal initiating a call for reception time information from a time information source in the second communications device wherein
- the second communications device passes on the data packet to a third communications device,
- pass-on-information indicates the time at which the data packet is passed on to the third communications device, and
- the reception time information and the pass-on-information are passed on, with the data packet.
