Abstract
(EN) Disclosed in embodiments of the invention are a service transmission method and a first transmission device. The method comprises: mapping n client signals all having a rate t to ms/t sub-load regions of m FlexO frames, wherein a payload region of each of the m FlexO frames is divided into s/t sub-load regions, and each FlexO frame is transmitted via a FlexO channel having a transmission rate s; configuring FlexO type information, timeslot overhead information, and signal mapping information for each FlexO frame; and transmitting the m FlexO frames to a second transmission device through m FlexO channels having a transmission rate s, wherein the second transmission device is used to parse, according to the FlexO type information, timeslot overhead information, and signal mapping information, the client signals carried by the ms/t sub-load regions. The embodiments of the invention provide an improvement in flexibility of service transmission.
(FR) Conformément à des modes de réalisation, l'invention concerne un procédé de transmission de service et un premier dispositif de transmission. Le procédé consiste à : mapper n signaux de client ayant tous un débit t à ms/t régions de sous-charge de m trames FlexO, une région de données utiles de chacune des m trames FlexO étant divisée en s/t régions de sous-charge, et chaque trame FlexO étant transmise par l'intermédiaire d'un canal FlexO ayant un débit de transmission s ; configurer des informations de type FlexO, des informations de surdébit de créneau temporel, et des informations de mappage de signaux pour chaque trame FlexO ; et transmettre les m trames FlexO à un second dispositif de transmission par l'intermédiaire de m canaux FlexO ayant un débit de transmission s, le second dispositif de transmission étant utilisé pour analyser, selon les informations de type FlexO, les informations de surdébit de créneau temporel, et les informations de mappage de signaux, les signaux de client transportés par les ms/t régions de sous-charge. Les modes de réalisation de l'invention permettent d'améliorer la flexibilité de la transmission de service.
(ZH) 本发明实施例公开了一种业务传送方法和第一传送设备,该方法包括:将n个速率均为t的客户信号映射到m路FlexO帧的ms/t个子负荷区上,m路FlexO帧中每路FlexO帧的净荷区被划分为s/t个子负荷区,每路FlexO帧用于通过一路传输速率为s的FlexO通道传输;为每路FlexO帧配置FlexO类型信息、时隙开销信息和信号映射信息;通过m路传输速率为s的FlexO通道向第二传送设备传输m路FlexO帧,第二传送设备用于根据FlexO类型信息、时隙开销信息和信号映射信息解析ms/t个子负荷区承载的客户信号。采用本发明实施例,提高了业务传送的灵活性。
