Abstract: Embodiments of the present invention disclose a method for the generic mapping procedure GMP mapping, a method for GMP demapping, and an apparatus. The method for mapping includes: carrying, in an overhead GMP OH of the ith GMP block container, information about a TS that needs to be occupied by the (i+n)th GMP block container; adjusting the (i+n)th GMP block container according to the information about the TS that needs to be occupied by the (i+n)th GMP block container; performing, according to the adjusted (i+n)th GMP block container, the GMP mapping on customer service data to be sent, so that a receive end is capable of adopting a corresponding demapping manner according to a change of the block container, which implements lossless mapping and demapping processing by adopting a GMP for a variable block container.

Abstract: A method, a system, and a device for transmitting data in an OTN are disclosed herein. The method for transmitting data in an OTN includes: mapping the at least one pair of ODU0's to an ODTU to form an ODTUvkt, wherein k is greater than or equal to 1, t is 2 or 3, and an external structure of the ODTUvkt is the same as an external structure of an ODTUkt; and mapping the ODTUvkt to timeslot i and timeslot i+n of a 1.25 G ODUt, indicating the type of at least one pair of ODU0's carried in timeslot i to be ODUk, and transmitting the ODUk to a destination node.
