Abstract

Selon l'invention, pour permettre une réduction de la fréquence des délais d'attente de communication dues au retard de réponse de communication, un appareil de mise à jour de temps d'attente de réponse met à jour un temps d'attente d'un premier appareil de communication par rapport à une réponse de communication de la part d'un deuxième appareil de communication à une valeur qui augmente de manière monotone en fonction d'un temps de réponse de communication entre le premier appareil de communication et le deuxième appareil de communication.
