Abstract

La présente invention concerne un procédé, un dispositif, un centre de données et un système de détection de latence de vieillissement. Le procédé consiste : à envoyer à un centre de données un message de demande utilisé pour ordonner au centre de données d'interroger un premier protocole de commande de transmission (TCP) de valeur de latence de vieillissement ; à recevoir des informations de rétroaction envoyées par le centre de données pour le message de demande ; et si les informations de rétroaction comprennent la première valeur de latence de vieillissement TCP, à déterminer ensuite une valeur de latence de vieillissement TCP cible en fonction de la première valeur de latence de vieillissement TCP. Le procédé de détection de latence de vieillissement selon la présente invention interroge la première valeur de latence de vieillissement TCP par l'intermédiaire du centre de données, et effectue une détection sur la base de la première valeur de latence de vieillissement TCP, améliorant ainsi efficacement l'efficacité de détection.
