    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： There is described a method for transmitting N parallel data flows on a parallel bus. The method comprises, at a first communication device: generating a further parallel data flow comprising alignment words periodically distributed with a period; at each period, rotating the N of parallel data flows and the further parallel data flow thus generating N+1 rotated parallel data flows, each comprising part of the alignment words periodically distributed with a frame period; transmitting the N+1 rotated parallel data flows on respective physical connections of the parallel bus. The method further comprises, at a second communication device: aligning the N+1 rotated parallel data flows by using the alignment words, thus compensating skew and obtaining N+1 aligned parallel data flows; and at each period, derotating the N+1 aligned parallel data flows, thus generating N de-rotated parallel data flows corresponding to the N parallel data flows.

    摘要： Equipment protection of a switch matrix (SM) in a network node, which contains a number of matrix modules (M1.1-M4.4, E1.5-E4.6) is achieved by slicing an input signal into k parallel signal slices (x(0)-x(3))with k>2; coding the k signal slices into a number of n coded signal slices (x(0)-x(5)) with n>k+1 using an error correcting code to add redundancy to said input signal; switching said n coded signal slices through the switching matrix (SM) via n distinct matrix modules; and decoding the n coded signal slices into k decoded signal slices to correct errors introduced while passing through said switch matrix. Preferably, the switch matrix (SM) contains a first number of matrix boards (MB1-MB4, EBS, EB6), each carrying a second number of matrix modules (M1.1-M4.4, E1.5-E4.6). The n coded signal slices are switched via matrix modules on n distinct matrix boards.
