Remarques

TCP est un protocole de couche de transport chargé d’envoyer et de recevoir de manière fiable des paquets de données. Il est défini dans la RFC 793 de l’IETF.

Pour plus d’informations sur les statistiques de trafic TCP disponibles pour les applications, consultez la documentation de classe TcpStatistics . Notez que l’objet retourné par cette méthode reflète les statistiques au moment de la création de l’objet TcpStatistics . Ces informations ne sont pas mises à jour dynamiquement.
