Abstract
A method for transmitting a client signal in an optical transport network includes: dividing a payload of an optical payload unit signal into m first-granularity tributary slots; dividing one of the m first-granularity tributary slots into n second-granularity tributary slots, where a rate of the first-granularity tributary slot is n times that of the second-granularity tributary slot, m is a positive integer, and n is a positive integer greater than 1; mapping a first client signal onto a payload in which one or more of the n second-granularity tributary slots are located; adding an overhead of the first-granularity tributary slot and an overhead of the second-granularity tributary slot for the optical payload unit signal, to generate an optical data unit signal; and sending the optical data unit signal.
