Method of transmitting data between a source node and destination node

A network node arranged to communicate with one or more destination nodes across a communication network, the network node comprising:

• a network node processor configured to:
• divide data into frames, each frame comprising a number of packets N, where, at the one or more destination nodes, processing of an information packet p of the frame is conditional on receipt of the data for any information packet i of the frame where i<p;
• allocate, for each network path k, a number of sequential transmission slots s, each for transmitting a given packet p of the frame;
• provide a set D of possible assignments x of packets to transmission slots for a frame;
• determine an assignment x based upon in-order delivery delay of the packets;
• and
• transmit the packets in accordance with the determined assignment x.

A computer program product comprising a non-transitory computer readable medium storing computer readable code which when executed in a computing device is arranged to perform a method of transmitting data between a source node and destination node connected via multiple paths of a heterogeneous network by:

• dividing the data into frames, each frame comprising a number of packets N, where, at the destination node, processing of an information packet p of the frame is conditional on receipt of the data for any information packet i of the frame where i<p;
• allocating, for each network path k, a number of sequential transmission slots s, each for transmitting a given packet p of the frame;
• providing a set D of possible assignments x of packets to transmission slots for a frame;
• determining an assignment x with in-order delivery delay of the packets;
• and
• transmitting the packets in accordance with the determined assignment x.
