Abstract:
1. A method of switching comprising: employing a plurality of switch units each switch unit having m inward ports and n outward ports, m>1, n>1, arranging said switch units into Π matrices, Π>1, each matrix having ν rows and μ columns, ν>1, μ>1, wherein ν×m=μ×n; connecting each source node from among a plurality of source nodes to a switch unit in each of said μ columns in each of said matrices; connecting each sink node from among a plurality of sink nodes to each switch unit of a respective column in each matrix; maintaining at said each source node identifiers of Π switch units, one in each of said Π matrices, connecting to said each sink node; and selecting, at a controller of a specific source node, a preferred switch unit, among respective Π switch units directly connecting said specific source node to a specific sink node, for establishing a simple path.
