Abstract
Official abstract text for this publication.
The embodiments of the present invention disclose method and apparatus for mapping and de-mapping in an optical transport network, where the mapping method includes: constructing an Optical Channel Data Tributary Unit (ODTU) according to an amount M of time slots of a High Order Optical Channel Payload Unit (HO OPU) to be occupied by a Low Order Optical Channel Data Unit (LO ODU); mapping the LO ODU to a payload area of the ODTU in a M-byte granularity; encapsulating overhead information to the overhead area of the ODTU; and multiplexing the ODTU, which has been mapped the LO ODU and encapsulated with the overhead information, to the HO OPU, so as to provide a high-efficient and universal mode for mapping the LO ODU to the HO OPU.
First claim
Opening claim text (preview).
The invention claimed is: 1. A mapping method used in an Optical Transport Network (OTN), comprising: constructing an Optical Channel Data Tributary Unit (ODTU) according to an integer value M larger than 1, wherein the integer value M equals the number of time slots of a High Order Optical Channel Payload Unit (HO OPU) that are to be occupied by data of a Low Order Optical Channel Data Unit (LO ODU) via the ODTU; mapping the data of the LO ODU into a payload area of the ODTU by…
