Physical implementation of the switching fabric of a massive broadband switching network constructed from recursive 2-stage interconnection. The recursive 2-stage construction is realized through a hierarchical levels of implementation, including inside-chip implementation, PCB implementation, orthogonal...http://www.google.com/patents/US7072334?utm_source=gb-gplus-sharePatent US7072334 - Physical implementation of switching fabrics constructed from recursive 2-stage interconnection
