Abstract
A method is disclosed for transmitting data between a source node and destination node connected via multiple paths of a heterogeneous network, at least one of the paths delivering packets with a non-deterministic delivery time. Data is divided into frames, each frame comprising a number of packets, where processing by the destination node of an information packet p is conditional on receipt of the data for any information packet i where i<p. A number of sequential transmission slots s, each for transmitting a given packet p of a frame, are allocated for each network path k. A set D of possible assignments of packets to transmission slots for a frame are provided. The method comprises determining an assignment x with minimum in-order delivery delay of said packets based on expected arrival times of packets to their destination and expected reordering delay for packets. Packets are then transmitted in accordance with the determined assignment x.
