Abstract
A method of transporting a client signal across an optical transport network (OTN) comprises dividing a received client signal into a plurality of parallel signals at a lower bit rate. The parallel signals are mapped into a respective number of optical data units (ODUs), each ODU having payload bytes and overhead bytes. Each ODU is mapped into a respective optical transport unit (OTUs) having payload bytes and overhead bytes. The OTUs are transmitted across respective optical carriers. Optical channel control information is inserted into the overhead bytes of the ODU and/or OTU. The optical channel control information is used to request a change in the optical carriers used to transport the client signal.
