Abstract

L'invention concerne un procédé et un système de restauration de transmission efficace en fonction d'une conversion d'état de réseau. D'après un mode de réalisation, un procédé de restauration de transmission peut comprendre les étapes consistant à : générer une valeur d'identification unique qui ne chevauche pas des données demandées devant être transmises à un côté réception ; ajouter la valeur d'identification aux données et transmettre simultanément au côté réception les données et la valeur d'identification ; surveiller une conversion d'état de réseau pendant le processus de transmission des données ; transmettre la valeur d'identification au côté réception lorsqu'il n'est pas confirmé que la transmission des données est terminée en raison de la conversion d'état de réseau ; et traiter un résultat de réception de la valeur d'identification à titre de résultat de réception des données lorsqu'une réponse à la réception des données est reçue en tant que réponse à la valeur d'identification provenant du côté réception.
