Abstract:
1. A method for transmitting client signals, the method comprising: mapping a client signal to a low-order Optical Channel Data Unit (ODU) via a Generic Framing Procedure (GFP) scheme, wherein the low-order ODU is sized to M equal sized timeslots of a high-order Optical Channel Payload Unit-k (OPUk), wherein the high-order OPUk is divided into N equal sized timeslots, wherein M is any one of a number group from 1 to N; wherein if k=2, then N=8, if k=3, then N=32, and if k=4, then N=80; mapping the low-order ODU with the client signal to M equal sized timeslots of the high-order OPUk via a Generic Mapping Procedure (GMP) scheme; forming an Optical Channel Transport Unit (OTU) with the high-order OPUk and overheads; and transmitting the OTU.
