1. An avionics data communication network, comprising:
a computing device configured to:
asynchronously transmit data packets in parallel via three or more redundant network interface controllers (NICs); and
bound the data packets offered to the avionics data communication network using a token bucket filter (TBF);
three or more redundant network switches, each configured to receive and relay the data packets from a different NIC of the three or more redundant NICs of the computing device, wherein each of the computing device and the three or more redundant network switches implement prioritized fair share schedulers to regulate transmission of the data packets; and
an avionics device configured to receive the data packets from the computing device within a deterministic end-to-end transmission delay bound, the avionics device receiving the data packets via at least one of the three or more redundant network switches.
