Abstract
(EN)
A device may include a first interface and a second interface. The device may also include memory containing a set of rules and representations of pre-defined violations thereof. The de vice may also include digital logic programmed to: (i) receive, by way of the first interlace, an Ethernet frame containing Ethernet header fields and an Ethernet payload, wherein the Ethernet payload contains a payload; (ii) extract data from the Ethernet header fields, wherein the data defines a transaction that is functionally equivalent to a further transaction that is defined by the payload; (hi) apply the set of rules to tire transaction, wherein doing so involves comparing fields m the data to values and concluding that the transaction, does not contain any pre-defined violations; and (iv) modify the Ethernet frame to contain content based on the payload, and transmit the Ethernet frame out the second interlace.

L'invention concerne un dispositif comprenant une première interface et une seconde interface. Le dispositif peut également comprendre une mémoire contenant un ensemble de règles et des représentations de violations prédéfinies de celle-ci. Le dispositif peut également comprendre une logique numérique programmée pour : (i) recevoir, au moyen du premier entrelacement, une trame Ethernet contenant des champs d'en-tête Ethernet et une charge utile Ethernet, la charge utile Ethernet contenant une charge utile ; (ii) extraire des données des champs d'en-tête Ethernet, les données définissant une transaction qui est fonctionnellement équivalente à une autre transaction qui est définie par la charge utile ; (hi) appliquer l'ensemble de règles à la transaction, en comparant des champs dans les données à des valeurs et en concluant que la transaction ne contient pas de violations prédéfinies ; et (iv) modifier la trame Ethernet de sorte qu’elle contienne un contenu en fonction de la charge utile, et transmettre la trame Ethernet hors du second entrelacement.
