Abstract
An improved packet routing network is disclosed in which inbound packets do not have to arrive synchronously. The network includes collision avoidance circuitry and an m stage switching network where the number of input lines to the network is 2.sup.m. Each stage in the first (m-1) stages further comprises one or more line reducing circuits. Each line reducing circuit transfers each data packet input on an input line thereof to one of a plurality of output lines thereof. The number of line reducing input lines is greater than the number of line reducing output lines. The transfer is accomplished in a manner guaranteeing that no two data packets are output on the same line reducing output line.
