Abstract

A technique is provided for transmitting client data included in a client signal via an optical transmission path of an optical transport network. The optical transport network uses transport frames include a transport frame period for transmitting client data. The method includes receiving multiple client entities comprising multiple client data bits; determining the number of client data entities received during a transport frame period to establish a mean number of client data entities to be included in a transport frame, the mean number of client data entities corresponding to a mean number of client data bits; mapping multiple client data entities into the transport frame wherein mapping comprises alternately adding and subtracting an amount of client data bits to/from the mean number of client data bits for at least two consecutive transport frames; and transmitting the transport frames comprising the client data via the optical transport network.
