Abstract

In the data packet router disclosed herein, a matrix of crosspoint switch elements connects data sources to selected destinations during each of a succession of intervals. Allocation of switch elements to desired connections is accomplished by a process which provides a data array having a number of data elements corresponding to the number of switch elements. During each interval, a source is assigned to each of the data elements in accordance with a first current pseudo-random shuffle pattern and a respective destination is assigned to each of the data elements in accordance with a second current pseudo-random shuffle pattern. A new set of shuffle patterns is generated during each interval. An incremental testing is performed across the data array to locate matches not previously allocated and each match found is successively allocated to this switch element corresponding to the data element. After testing, the complete array of switch elements are operated, during a subsequent interval, in accordance with the previously determined allocations.
