Abstract: A method for transmitting data packets from a first node to a second node. The method includes transmitting the data packet from the first node to the one second node where each data packet is determined to be sent according to a first or a second transmission mode, where, in the first transmission mode, the data packet is transmitted to the second node according to a prescheduled scheme, where the prescheduled scheme defines a cyclic one-to-one assignment between first and second node over time slots so that the data packet is forwarded to the second node during that time slot the one-to-one assignment of which assigns the first node with the one second node and in the second transmission mode, the data packet is transmitted during an actual time slot to the second node while overruling the prescheduled scheme.

Abstract: The invention relates to a method for transmitting one or more data packets from a first node (2, 6) to one of a number of second nodes (6, 3) connected by a switching network (4, 5), wherein the data packet is transmitted from the first node (2, 6) to the one second node (6, 3) according to a transmission mode, wherein for each data packet it is determined whether it is sent according to a first or a second transmission mode depending on a network condition; wherein in the first transmission mode the data packet is transmitted to the second node (6, 3) according to a prescheduled scheme, wherein the prescheduled scheme defines a cyclic one-to-one assignment between the first (2, 6) and the second node (6, 3) over time slots so that the data packet is forwarded to the second node (6, 3) during that time slot the one-to-one assignment of which assigns the first node (2, 6) with the one second node (6, 3); wherein in the second transmission mode the data packet is transmitted during an actual time slot to the second node (6, 3) while overruling the prescheduled scheme.
