Abstract: A method for efficient utilization of a transport capacity provided by an optical transport network includes mapping client signals comprising lower order optical data units into optical data tributary units, each requiring a number of tributary slots of an aggregate payload area having a size corresponding to the available aggregated OPU payload areas of Nx independent higher order optical data units to be transported. The method further includes multiplexing the optical data tributary units into the aggregate payload area. The method further includes mapping the tributary slots of the aggregate payload area into tributary slots provided by the OPU payload areas of the Nx independent higher order Optical data units according to a predefined mapping rule. The method further includes multiplexing the Nx independent optical data units containing the payload areas or transmitting them as optical transport units.

Abstract: A method for removing static differential delays resulting from an independent transport of the client signals of a client signal bundle through an optical transport network, OTN, which comprises OTN mappers mapping received client signals to ODU signals transported to OTN demappers demapping received ODU signals to client signals, wherein a process slave, PS, at the OTN mapper end of said OTN network supplies continuously or in response to a received request information about timing relations between the client signals of said client signal bundle to a process master, PM, at the OTN demapper end of said OTN network used by the process master, PM, to remove the static differential delays between the client signals of the respective client signal bundle.
