Reduced banyan-type multiplane rearrangeable switching networks

The new concept of the multiplane rearrangeable switching network is presented. The new switching network's architecture is based on the well-known baseline network (the log
₂
(N, 0, 1) switching network). This new architecture can easily be obtained from the baseline network by the removal of some switching elements. It is therefore called the reduced baseline switching network and is denoted by log
^r

₂
((N, 0, 1). The new multiplane rearrangeable reduced baseline switching network requires fewer switching elements and crosspoints than the multiplane switching network which is based on the plain baseline network.
