Summary:Methods, systems, and computer readable media for rapid filtering of opaque data traffic are disclosed. According to one method, the method includes receiving a packet containing a payload. The method also includes analyzing a portion of the payload for determining whether the packet contains compressed or encrypted data. The method further includes performing, if the packet contains compressed or encrypted data, at least one of sending the packet to an opaque traffic analysis engine for analysis, discarding the packet, logging the packet, or marking the packet. La présente invention concerne des procédés, des systèmes et des supports lisibles par un ordinateur permettant un filtrage rapide d'un trafic de données opaque. Le procédé comprend les étapes consistant à : recevoir un paquet contenant une charge utile ; analyser une partie de la charge utile afin de déterminer si le paquet contient des données compressées ou chiffrées ; et, le cas échéant, envoyer le paquet à un moteur d'analyse de trafic opaque à des fins d'analyse et/ou rejeter le paquet et/ou le consigner et/ou le marquer.
