Abstract

本申请揭示了一种光传送网中低速业务数据的处理方法、装置和系统，用以解决现有低速业务承载方法存在的复杂度高的问题。该方法包括：首先，将低速业务数据映射到一个新定义的低速数据帧中，其中，所述低速数据帧的速率和所述低速业务数据的速率匹配，该数据帧包括开销区和净荷区，所述净荷区用于承载所述低速业务数据，所述低速数据帧的净荷区的速率不小于所述低速业务数据的速率，所述低速业务数据的速率小于1Gbps；然后，将所述低速数据帧映射到另一数据帧的一个或多个时隙中，所述时隙的速率不大于100Mbps；最后将所述另一数据帧映射到光传输单元(OTU)帧并发送所述OTU帧。通过本申请揭示的低速处理方法，可以直接采用新的OTN帧来进行业务承载，发送和处理复杂度降低，处理速度也较快。
