== 1) Functional Description ==

The Virtual Dspin Array is a two-dimensionnal array composed of [wiki:Component/VirtualDspinRouter VirtualDspinRouter], for routing paquets of two virtual channels on the same physic network.

Two Virtual Dspin Arrays can be combined, one for request paquets, other for response paquets to form a [wiki:Component/VirtualDspinNetwork VirtualDspinNetwork].
