1. A method to reduce latency of frames transiting through a network device with a plurality of input ports and a plurality of output ports supporting at least a lower and a higher frame priorities, the method comprising:
receiving said frames for transmission at an output port of the plurality of output ports, from the plurality of input ports;
queuing in a queue said received frames based on a frame arrival time and a priority associated with the frame;
selecting a first frame of a first frame priority to transmit on the output port from the queue;
stopping transmission of the first frame in response to receiving a second frame with a second frame priority wherein said second frame priority is higher priority than said first frame priority;
transmitting an invalid frame check sequence;
transmitting the second frame; and
retransmitting the first frame after the transmission of the second frame is completed,
wherein an updated time-stamp associated with the second frame is reapplied upon said second frame being retransmitted.
