How does the cut-through switching technique work?
Ans) Cut-Through switching copies only the destination address which is the first 6 bytes after the =frame preamble into its buffer. The LAN switch then looks up the destination address in its switching table and verifies the outgoing interface. The frame is then sent to the interface. A cut-through switch gives reduced latency because it starts to forward the frame as soon as it read the destination address and verifies the outgoing interface.
