Disclosed herein is technology to reduce latency of frames through a network device supporting various priorities. In an implementation, a method comprises configuring one or more priorities with a preemptive right over other one or more of said plurality of priorities; receiving frames in a sequence, each of the frames having a frame priority comprising of one of said plurality of priorities; queuing the received frames in a predetermined order based on a frame arrival time and the frame priority; transmitting a current frame based on a current frame priority and current frame arrival time; stopping transmission of the current frame when a later frame in the sequence is received that has a later frame priority with preemptive right over the current frame priority; transmitting an invalid frame check sequence; transmitting the later frame; and restarting the transmission of the current frame after transmitting the later frame.

Preemptive packet transmission

An integrated pluggable optical tap module configured to be coupled to a host interface of a network equipment for tapping a signal of an optical transport link comprises a first, a second optical interface, and an active optical receiver. The optical pluggable module also includes a passive optical tap for splitting a signal received from the first optical interface and transmitting the signal on the second optical interface and a copy of the signal to the active optical receiver. The active optical receiver converts said signal to an electrical signal for transmission to the host interface.
