ABSTRACT:
The addresses of an irregular group of outputs of an asynchronous switching node distributing cells dynamically to outputs constituting an irregular group cannot be related by any mathematical relationship. To distribute cells applied to inputs of the node as regularly as possible, the node includes translator circuits determining at the network input an internal routing label which identifies a regular subgroup of outputs, each of which may consist of only one output. To this end it uses an algorithm dependent on the rank of the input receiving the cell and the time at which the cell is received. This algorithm therefore achieves spatial decorrelation and temporal decorrelation of the cells. The asynchronous switching node can be used in ATM telecommunication networks, for example.
