1. An interconnection network comprising:

  • backplane means for receiving X pluggable node cards, and comprising X backplane connector groups, each backplane connector group adapted to receive mating connectors from a pluggable node card and including X/2 connectors, said backplane means including first permanent wiring which provides a first set of interconnections between a first subset of pairs of connectors in said backplane connector groups and second permanent wiring which provides a second set of interconnections between a second subset of pairs of connectors in said backplane connector groups, each pair of connectors comprising a connector in one backplane connector group and a connector in another backplane connector group, said first set of interconnections and second set of interconnections interconnecting complementary pairs of said connectors;

    a plurality of node cards, each including a card connector group for pluggably mating with a backplane connector group, each node card further including at least an additional connector adapted to receive a cable interconnection;

    processor means positioned on each node card;

    switch means on each node card for simultaneously connecting said processor means to at least two or more connectors of a card connector group.
