1. A method of source routing to implement device-to-device communications across a hybrid distributed device control network, said method comprising:

  • a) originating a packet at a source node where said packet is being broadcast to all the nodes in a subnetwork in which the additional steps of;

    identifying the packet as a broadcast packet;

    encapsulating the broadcast packet in a protocol-specific packet used by the destination subnetwork; and

    passing said broadcast packet to the nodes on the destination subnetwork;

    b) having the packet consists of sections including;

    i) a header, ii) a network path, and iii) data;

    c) encapsulating the packet in a protocol-specific packet used by the subnetwork of the source node;

    d) passing said protocol-specific packet to the first destination router in the network path;

    e) having the router decapsulate the protocol-specific packet;

    f) increment the next path destination index counter by one;

    g) using the next path destination index counter to point to the next path destination address;

    h) encapsulating the packet in a protocol-specific packet used by the next destination subnetwork where said encapsulation packet has an encapsulation header that contains a destination address;

    i) passing said protocol-specific packet to the next destination router in the network path;

    j) repeating the previous five steps until the packet reaches the final destination node;

    k) identifying the packet as a broadcast packet; and

    l) encapsulating the broadcast packet in a protocol-specific packet used by the destination subnetwork; and

    m) passing said broadcast packet to the nodes on the destination subnetwork;

    n) having a response packet consist of sections including;

    i) a header, ii) a network path, and iii) data;

    o) creating an acknowledgement network path by inversing the network path of the packet;

    p) encapsulating the response packet in a protocol-specific packet used by the subnetwork of the destination node;

    q) passing said protocol-specific packet to the first destination router in the acknowledgement network path;

    r) having the router decapsulate the protocol-specific packet;

    s) increment the next path destination index counter by one;

    t) using the next path destination index counter to point to the next path destination address;

    u) encapsulating the response packet in a protocol-specific packet used by the destination addresss subnetwork;

    v) passing said protocol-specific packet to the next destination router in the network path; and

    w) repeating the previous five steps until the response packet reaches the source node.
