Abstract
The present invention discloses a method and a system for transparent transport of optical channel transmission unit (OTU) signals via an optical transport network (OTN), which includes a transmitting unit and a receiving unit at the OTN network boundary: the transmitting unit converts an OTUj signal mapping entering the OTN network into OTUk signals of the current OTN network for transmission. In the mean time, it reserves the OTUj control overhead, or extracts the OTUj control overhead and transfers it to the reserved overhead location; the receiving unit receives the OTUk signals arriving at the OTN network boundary, and performs demapping and converting them into OTUj signals. In the mean time, it successively uses the aforementioned reserved OTUj control overhead, or extracts the aforementioned OTUj control overhead from the aforementioned reserved control overhead location for subsequent use, and transfers the OTUj signals from the current OTN network; the aforementioned j and k represent the rate rank of the aforementioned OTU, respectively. The present invention is capable of achieving total transparent transport of OTU signals, including a payload portion and a control overhead.
