Abstract

La présente demande concerne un procédé et un appareil de transmission de données. Le procédé comprend les étapes suivantes : un premier dispositif obtient une cellule d'unité de service optique (OSU) ; le premier dispositif mappe la cellule OSU à une trame STM -1 ; le premier dispositif envoie la trame STM -1 à un second dispositif ; le second dispositif reçoit la trame STM -1 du premier dispositif, la trame STM -1 comprenant la cellule OSU ; et le second dispositif dé-mappe la trame STM -1 pour obtenir la cellule OSU. Selon la solution de la présente demande, lorsqu'un réseau SDH/MSTP se trouve entre le premier dispositif et le second dispositif, le premier dispositif mappe la cellule OSU à la trame STM -1 et l'envoie et le second dispositif reçoit la trame STM -1 et dé-mappe la cellule OSU à partir de la trame STM -1, mettant ainsi en œuvre une transmission de bout en bout une fois que des données sont mappées sur la cellule OSU.
