| 摘要 |
The invention is directed to a switching device (Sij) adapted to connects parts of a computer interconnection network, having N input ports (Ia-Ih) and N output ports (Oa-Oh), the device adapted for routing data packets by means of direct crosspoints (CPxy), the direct crosspoints configured for enabling direct connectivity between each of the N input ports to a subset m<N of the output ports only, in accordance with connectivity needs of the computer interconnection network. Preferably, it furelm.) they comprises an additional circuitry (L) and additional crosspoints (APx,L, APL,y) configured such that at least some of the input ports of the switching device can be indirectly connected to at least some of the output ports of the switching device, through the additional circuitry. The invention further concerns an interconnection network and a method for routing data.
