Abstract
A packet parallel interconnection network for routing packets in parallel form comprises a three-dimensional space domain switch which interconnects a plurality of time domain switches in the form of multiple two level bus systems with separate data and control paths. The space domain switch comprises one control plane and a plurality of data switching planes such that the i.sup.th data switching plane routes the i.sup.th data slice of a packet. The control plane and the data switching planes comprise output buffered crosspoint switches. The control plane processes address information in the packets to be routed and broadcasts routing information to the data switching planes to control the routing of data slices by the data switching planes. It is a significant advantage of the time and space domain switches that decoupled control and data paths provide for overlapped control processing and data routing. The inventive interconnection network is especially useful for implementing a parallel processing system for processing database queries.
