METHOD AND OPTICAL SWITCHING NODE FOR TRANSMITTING DATA PACKETS IN AN OPTICAL TRANSMISSION NETWORK

摘要

The present document relates to a method for transmitting client data packets through an optical transmission network comprising multiple nodes, comprising:- receiving (705) a first container (200) at a node (110a, 110b, 110c), the first container comprising a container header (210) and a container payload portion (220), wherein the container header (210) comprises at least information regarding a destination node of the first container (200) and wherein the container payload portion (220) includes a data portion comprising information associated with one or more client data packets, said data portion being directed to the destination node of the first container (200), the container header (210) further comprising occupancy information indicative of the space occupied by the data portion in the container payload portion (220) or about free space in the container payload portion (220);- determining (740) whether free space is available in the container payload portion (220) for carrying a further data portion);- providing the further data portion, the further data portion comprising information associated with further client data packets being directed to the destination node of the first container (200); and- transmitting (760), in the optical domain, a second container (220) comprising a container header (210) including updated occupancy information and a container payload portion (220) including the data portions.
