Abstract
A network device receives a label-switched-path (LSP) labeled data packet, maps the LSP labeled data packet to an input queue, maps a data packet in the input queue to an output queue based on a received LSP label value and a received exp label value, and transmits the LSP labeled data packet from the output queue.
