Patent

CA 2465127

A system and method of analyzing data traffic associated with messages being sent through a communications network is provided. The method comprises receiving data traffic, obtaining characteristics of data traffic and identifying packet flooding by analyzing the characteristics. The system and method may analyze the data traffic to determine whether the data traffic is not bursty. The system and method may also correlate characteristics of the data traffic to a Hurst parameter. The system and method may respond to packet flooding by terminating a connection associated with data traffic. Denial of service attacks can be prevented by analyzing statistics regarding the network data traffic.

L'invention concerne un système et un procédé d'analyse du trafic de données associé aux messages envoyés par un réseau de communication. Ce procédé consiste à recevoir le trafic de données, à obtenir les caractéristiques du trafic de données et à identifier l'inondation de paquets par l'analyse des caractéristiques. Ce système et ce procédé permettent d'analyser le trafic de données pour déterminer si le trafic de données s'effectue par rafale. Ce système et ce procédé permettent de mettre en corrélation les caractéristiques du trafic de données avec un paramètre de Hurst. Ce système et ce procédé permettent de réagir à une inondation de paquets en mettant un terme à la communication associée au trafic de données. On peut prévenir toute interdiction d'attaques de service par l'analyse des statistiques concernant le trafic de données réseau.
