Qu'est-ce que « Hardware trigger, cut-through decision » ?

A hardware trigger is logic on a network card that watches a market-data stream for a condition set in advance by software (a price crossing a threshold, a trade on a given instrument) and, when it occurs, starts an order without the host’s involvement. A cut-through decision is a decision taken as soon as the bytes it depends on have arrived, before the frame that carries them has ended or been checked.
