  • receiving an original signal at an ingress capable network device in the compatible public network and that includes a destination service address;

    forwarding a destination address identifier corresponding to the destination service address to a local naming system including at least one look-up table having registered pairs of destination address identifiers and internal routing addresses internal to the compatible public network;

    performing a look-up between the destination address identifier and at least one internal routing address corresponding thereto;

    returning at least one internal routing address to the ingress capable network device from the local naming system;

    substituting the destination address identifier with the internal routing address in a transit signal corresponding to the original signal while retaining said destination address identifier in a separate portion of said transit signal;

    routing said transit signal from the ingress capable network device through the compatible public network to an egress capable network device at the internal routing address;

    removing the internal routing address from said transit signal at said egress capable network device;

    restoring the destination service address to said transit signal; and
