1. An apparatus, comprising:

  • at least one non-transitory memory configured to store instructions; and

    one or more processors in communication with the at least one non-transitory memory, wherein the one or more processors is configured to execute the instructions to;

    receive, by a current node and from a previous node each in a network path along which first data is transmitted from a transmitting node to a receiving node in a network, network path information that is based on a first policy and is in a header of a first packet that is specified according to a label switching forwarding paradigm, the network path information in the header of the first packet being for use by the current node in transmitting the first data along the network path from the transmitting node to the receiving node in the network, where the network path information in the header of the first packet is received based on a node-scope specific identifier in a node-specific identifier space of a first node, and the node-scope specific identifier in the node-specific identifier space of the first node identifies, for the first node, a particular node in the network path along which the first data is transmitted;

    determine, by the current node, a node-scope specific identifier in a node-specific identifier space of a second node that identifies, for the second node, the particular node in the network path along which the first data is transmitted;

    map the node-scope specific identifier in the node-specific identifier space of the first node, to the node-scope specific identifier in the node-specific identifier space of the second node; and

    transmit, based on the node-scope specific identifier in the node-specific identifier space of the second node, the first data from the current node along the network path including the particular node.
