Method and apparatus for determining connections in a crossbar switch

摘要

A procedure is described for determining which source to connect to which destination in a non-blocking crossbar switch through which a plurality of sources may be attempting to gain access to a plurality of destinations. To this end, a metric is dynamically associated with each source and with each destination. Matching of sources to destinations is accomplished by iteratively assigning the destination having the smallest metric of all currently unmatched destinations to the source having the smallest metric of all currently unmatched source.
