ABSTRACT:
An adapter with two or more tails for interconnecting a node to a multi-stage interconnection network. The plurality of tails create various options. Option 1 connects a 2-tailed adapter to two sub-networks comprising the same network to provide cost effective non-blocking networks. Both serial and parallel searches through the sub-networks for non-blocked paths are supported. Option 2 connects the 2-tailed adapter to redundant networks to provide fault tolerance in case of the failure of one network. Option 3 forms direct connections amongst two or three nodes without requiring a central switch. Instead, each tail provides a direct link to a different node. Option 4 extends the adapter to provide additional tails; 3-tailed adapters provide direct links amongst four nodes, 4-tailed adapters provide direct links amongst five nodes, etc. Option 5 interconnects similar multi-tailed adapters to provide ring or hyper-cube networks without requiring a central switch.
