Abstract

Des modes de réalisation de la présente invention concernent un procédé de transmission de données et un dispositif électronique. Le procédé comprend les étapes suivantes : un dispositif de traitement de données de client réalise séparément une première tâche de téléchargement vers l'aval de données dans N serveurs et détermine N débits de transmission de données entre le dispositif de traitement de données de client et les N serveurs, N étant un entier positif ; déterminer, sur la base des N débits de transmission de données, dans au moins un serveur parmi les N serveurs, que le débit de transmission de données entre le ou les serveurs et le dispositif de traitement de données de client est supérieur ou égal à un débit de transmission de données prédéfini ; le dispositif de traitement de données de client réalise une seconde tâche de téléchargement vers l'aval de données au moyen du ou des serveurs. Puisque le débit de transmission de données entre le ou les serveurs déterminés et le client est élevé, le temps de transmission de données peut être raccourci, ce qui améliore effectivement l'efficacité avec laquelle le client obtient des données du serveur.
