1. A computer-readable non-transitory medium comprising one or more instructions for steering cloned traffic in a service function chain, the instructions when executed on a processor are operable to:

  • create a plurality of cloned data packets by creating copies of a data packet;

    activate a mirror bit in a network service header (NSH) of the cloned data packet, the mirror bit identifying the cloned packet to a service function forwarder network element as a cloned packet;

    set an indicator in each of the cloned data packets, the indicator representing that the corresponding cloned data packet is to be dropped after processing by a service function forwarder;

    identify a unique service path identifier for each cloned packet of the plurality of cloned packets; and

    transmit each of the cloned packets to a corresponding service function forwarder network element simultaneously based on the service function path identifier.
