AW th a cut-through arch tecture, the sw tch has to exam ne only the f rst 128 bytes of the

packet header to determ ne where the packet needs to be sent. The packet can then be

forwarded to the dest nat on before the sw tch rece ves the ent re packet. Th s

arch tecture results n very low latency, wh ch s requ red for HPC and H gh-Frequency

Trad ng (HFT) env ronments. W th a store-and-forward arch tecture, the sw tch rece ves

the ent re packet, analyzes t, and then determ nes where t should go. As a result, store-

and-forward arch tectures requ re larger buffers to rece ve data and usually have h gher

latency.
