Method for reducing the latency time for interactive data communication between a client computer (12) and a server computer (8), connected via a satellite network (1) containing a geostationary satellite (6), whereby a data processing program (10) is running on the server computer (8) producing data, which are transferred to the client computer (12) in the form of data packets (20, 20m, 20mUDP) and displayed by said client computer via a display medium (14) connected to the client computer (12) in the form of an interactive user program (26), and whereby the operator of the client computer (12) is given an input prompt (22) by the user program (26) to enter further data, which are transmitted to the server computer (8) in the form of further data packets (24, 24m, 24mUDP) via the satellite network (1), wherein the transmission of further data packets (24, 24m, 24mUDP) from the client computer (12) to the server computer (8) occurs essentially without an acknowledgement of the receipt of the transmitted further data packets (24, 24m, 24mUDP) by the server computer (8).
