Abstract: A method for transporting a client signal in an optical transport network (OTN) includes steps as follows. A byte number Cn of a client signal transported in a current OTN frame period is generated according to a client signal clock and a system clock. If the Cn of the current OTN frame falls in a certain range, a predetermined area in an optical channel payload unit-k (OPUk) overhead field is identified as normal, and the Cn is filled in the OPUk overhead field of the current OTN frame. Therefore, the reliability for transporting the client byte number can be improved and an OPUk overhead byte space needed for transporting the client signal byte number can be saved.

Abstract: Methods, apparatuses and systems for transporting multi-lane Ethernet signal are disclosed. The method primarily includes utilizing a plurality of timeslot channels and justification bytes configured in the OPUk-Xv to build up multiple virtually concatenated transport lanes; and transporting a lane of independent Ethernet data via each lane in the multiple transport lanes. Such schema allows to transparently transport multi-lane Ethernet signal over OTN and addresses the uncontrollability of the time delay occurred when multi-lane Ethernet signal traverse over OTN. In addition, the problem that the frequency offset does not fit the IEEE definition of the Ethernet interface is solved.
