Asynchronous switching node distributing dynamically cells to outputs forming an irregular group

摘要

The addresses of an irregular group of outputs of the node (ND) cannot be linked by a mathematical relationship. In order as regularly as possible to distribute cells applied to the input of the node, the latter includes translation circuits (T1, ... TN) determining, at the input of the network, an internal routing label identifying a regular subgroup of outputs, possibly consisting of a single output, according to an algorithm which is a function of the rank (j) of the input (Ij) receiving the said cell, and of the instant at which this cell was received. This algorithm thus achieves a spatial decorrelation and a time-based decorrelation of the cells. Application to ATM telecommunications networks. IMAGE
