1. A remote data concentrator (RDC) for an avionics Ethernet network, said RDC comprising:

  • a line replaceable unit (LRU) input;

    a first processing lane directly coupled to said LRU input, said first processing lane having a first output;

    a second processing lane directly coupled to said LRU input, said second processing lane having a second output; and

    a processor coupled to said first processing lane and said second processing lane and configured to route data from at least one of said first output and said second output to the Ethernet network, said processor comprising a link coupling said first processing lane with said second processing lane, said link configured to transfer data between said first processing lane and said second processing lane, wherein the first processing lane and the second processing lane process universal data protocol (UDP) messages in parallel, and wherein each processing lane synchronizes a virtual link sequence number for each UDP message transmitted between the first processing lane or the second processing lane and the Ethernet network.
