Patent ID: 7508824

Claim:
A method for transmitting data over a switchable data network, in which real-time critical and non real-time critical data are transmitted, comprising: transmitting the data by a computer in at least one transmission cycle with an adjustable duration, each transmission cycle divided into at least one first part for transmitting the realtime critical data for real-time control and at least one second part for transmitting the non real-time critical data; and establishing a communication interface by a computer between a first communication connection on a first transmission link with a first transmission cycle of a first length and a second communication connection on a second transmission link with a second transmission cycle of a second length, said establishment comprising: receiving a data packet comprising the realtime critical data according to a receive list assigned to the first transmission cycle, temporarily storing the received data packet comprising real-time critical data, and transmitting the stored data packet comprising the real-time data critical data according to a transmit list assigned to the second transmission cycle, wherein the data in the first and the second communication connections are exchanged in equidistant communication cycles.
