Abstract: The present invention provides a method, apparatus and system for transmitting and receiving a client signal. A client signal is mapped to a low-order ODU via a GFP scheme, wherein the low-order ODU is sized to M equal sized timeslots of a high-order OPUk, wherein the high-order OPUk is divided into N equal sized timeslots, wherein M is any one of a 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. The low-order ODU with the client signal is mapped to M equal sized timeslots of the high-order OPUk via a GMP scheme; and an OTU with the high-order OPUk and overheads is formed, and then the OTU is transmitted.

Abstract: The present invention provides a method, apparatus and system for transmitting and receiving a client signal. The method for transmitting a client signal includes, at the transmitting end, mapping a client signal to be transmitted to a corresponding low-order Optical Channel Data Unit (ODU) in a low-order ODU set, wherein low-order ODUs in the low-order ODU set having rates increased in order, and having rate correspondence relations with the client signals; mapping the low-order ODU to a timeslot of a high-order Optical Channel Payload Unit (OPU) in a high-order OPU set; and adding overheads to the high-order OPU to form an Optical Channel Transport Unit (OTU), and transferring the OTU to an Optical Transport Network (OTN) for transmission.

Abstract: A method and apparatus for address assignment and node scheduling within an ad-hoc communication system is provided herein. During operation a personal area network coordinator (PANC) (40) will divide a superframe (301) into a plurality of slots, assigning each sub-tree under the PANC's direct child node to each slot for communication with the PANC. Each sub-tree coordinator will be assigned a same logical address by the PANC. As a result, a sub-tree coordinator synchronizes to the PANC node in only one subsuperframe slot assigned by the PANC with different sub-tree coordinators synchronizing to the PANC in different slots.
