A network component for processing a packet can include a buffer configured to receive a packet, a forwarding unit configured to forward the packet received at the first buffer to a loopback port, and a transmitting unit configured to transmit the packet out of the loopback port. In addition, the network component can include a loopback unit configured to loop back the packet into the loopback port, a first identification unit configured to identify an egress port, and a second transmitting unit configured to transmit the packet looped back from the loopback port out of the egress port.
