Re: Fragment Free switch detail

Opposed to cut-through, which only inspects the destination address, fragement free assumes the frame is complete and forwards it when the minimal ethernet frame size of 64 bytes is met.

Most switches nowadays have sufficient processing power to run wirespeed store and forward switching, which is the most reliable of all three.
