Claim 0:
1. A data transmission method in an optical transport network (OTN), comprising:
mapping first-type service data to at least one payload block at at least one specific location in a plurality of consecutive payload blocks, wherein the plurality of consecutive payload blocks occupy a payload area of an optical data unit (ODU) frame;
mapping second-type service data to at least one payload block that is at any location in the plurality of consecutive payload blocks other than the at least one specific location;
mapping the ODU frame to an optical transport unit (OTU) frame or a flexible OTN (FlexO) frame; and
sending the OTU frame or the FlexO frame,
wherein
the first-type service data comprises first service data;
the plurality of consecutive payload blocks constitute one transport period; and
a location of a payload block occupied by the first service data in a first transport period is the same as a location of a payload block occupied by the first service data in a second transport period.
