Webtransfers. For example, when sending a large message, the HCA hardware on the sending node segments it into packets sized for transmission as it puts the data directly from the user’s memory onto the underlying wire. The receiving node’s HCA hardware reassembles these packets into the original message directly in the user’s memory. Fig. 1.
