    摘要： A method is described for controlling the switching of data packets through a network element. he method comprises the steps of receiving first data packets at an input module and storing at least part of the received first data packets into an input queue of the input module, calculating from the status of the input queue a first quantity of the first data packets and requesting the first quantity of data packets to be switched from the input module to an output module, granting a first allowed quantity being all or part of the first requested quantity of data packets to be switched. The method further includes the steps of, before the step of granting, receiving second data packets at the input module and storing at least part of the received second data packets into the input queue, calculating from the value of the first requested quantity and from the status of the input queue a second quantity of the second data packets and requesting the second quantity of data packets to be switched from the input module to the output module.

    摘要： It is disclosed an optical coherent receiver comprising a number of decoding blocks configured to implement iterations of a FEC iterative message-passing decoding algorithm. The decoding blocks are distributed into two (or more) parallel chains of cascaded decoding blocks. The receiver also comprises an intermediate circuit interposed between the two parallel chains. The optical coherent receiver is switchable between (i) a first operating mode, in which the intermediate circuit is inactive and the two parallel chains separately implement the FEC message-passing decoding algorithm on respective client channels; and (ii) a second operating mode, in which the intermediate circuit is active and the two parallel chains jointly implement the FEC message-passing decoding algorithm on a same client channel, by cooperating through the intermediate circuit.

    摘要： It is disclosed a method for decoding an information word from a set of coded words. The method comprises the steps of receiving a coded word, of selecting a coded word having the minimum distance from the received coded word from a pre-configured sub-set of the set of the coded words, wherein the sub-set is configured to at least two coded words having each other a distance higher than the minimum distance between the coded words of the set, and of decoding the information word from the selected coded word.
