10/100 Auto Negotiation Switch User's Guide byte packets are delayed by 1200 microseconds in a Store and Forward device versus 60 microseconds in a Cut-Through device. Store and Forward requires more memory because the DES-3224 must store the packet before sending it out. Advantages of Cut-Through Cut-Through is faster because the packet is sent as soon as the first 128 bytes are received.
