Q: There are several ways to transfer the switch, what is the difference?

A: The switch has cut through, Store and forward and fragment free three transmission modes.

First: Cut through transmission mode is forwarded after receiving the destination address. This way the delay is small, but corrupted data is forwarded as well.

Second: Store-and-forward transmission mode to receive the full data packet, check good or bad, forwarding, bad discard again. The transmission is reliable, but the delay is longer.

Third: Fragment free transmission mode received packets, more than 64bytes forwarding, less than 64bytes of discarded. This is a good or bad way between these two ways.
