En nous basant sur cette classification, nous avons pu réduire le champ de recherche d'attaques par détournement de l'ordre de 80%.Deuxì emement, nous avons proposé un système nous permettant d'analyser les cas suspects restants, A.2.5 Conclusion Dans cette section, 2006.

. Hu, Nous avons appliqué ce système sur un cas réel : le cas bulgare Notrepremì ere analyse (section A.2.4.1), similairè a celles faites dans ces précédent travaux, nous indique que cetévènementcetévènement réseau est effectivement le résultat d'une attaque par détournement intentionnelle. Cependant, notre seconde analyse (section A.2.4.2) utilise un ensemble de données qui nous permet d'´ elargir notre champ de vision, mais, en même temps, qui semble réfuter la thèse de l'attaque par détournement, 2007.
