(DE) VERFAHREN ZUR KLASSIFIKATION VON DATENSTRÖMEN UND NACHRICHTENWEITERLEITUNGSVORRICHTUNG
(EN) DATA STREAM CLASSIFICATION METHOD AND MESSAGE FORWARDING DEVICE
(FR) PROCÉDÉ DE CLASSIFICATION DE FLUX DE DONNÉES ET DISPOSITIF D'ACHEMINEMENT DE MESSAGES
Abstract
(EN) Embodiments of this application disclose a data flow classification method. The method is applied to a packet forwarding device between an internal network and an internet. The method in the embodiments of this application includes: A packet forwarding device obtains a plurality of data flows, and extracts address information and time information of each of the plurality of data flows. The packet forwarding device selects, from the plurality of data flows based on a source IP address of each data flow, a data flow set that is generated when a first client device accesses a plurality of services. The packet forwarding device determines, based on a destination IP address and a destination port number of each data flow in the data flow set, a service set that includes a first service and a second service and that is accessed by the first client device. The packet forwarding device determines a correlation between services in the service set based on time information of each data flow in the data flow set. Then, the packet forwarding device determines that the first service and the second service are used to implement a first application. In this case, the packet forwarding device determines that data flows corresponding to the first service and the second service are data flows of the first application.
(FR) Selon divers modes de réalisation, la présente invention concerne un procédé de classification de flux de données, appliqué à un dispositif d'acheminement de messages entre un réseau interne et l'internet. Le procédé selon les modes de réalisation de la présente invention comprend les étapes suivantes : un dispositif d'acheminement de messages acquiert une pluralité de flux de données, et extrait des informations d'adresse et des informations temporelles de chaque flux de données de la pluralité de flux de données ; en fonction d'une adresse IP d'origine de chaque flux de données, obtient, par filtrage de la pluralité de flux de données, un ensemble de flux de données généré lorsqu'un premier dispositif client accède à une pluralité de services ; détermine, en fonction d'une adresse IP de destination et d'un numéro de port de destination de chaque flux de données de l'ensemble de flux de données, un ensemble de services comprenant un premier service et un second service auquel accède le premier dispositif client ; en fonction des informations temporelles de chaque flux de données de l'ensemble de flux de données, détermine une corrélation entre divers services de l'ensemble de services ; puis détermine que le premier service et le second service sont utilisés pour mettre en œuvre une première application ; et ainsi le dispositif d'acheminement de messages détermine que le flux de données correspondant au premier service et au second service est un flux de données de la première application.
