Proactive quality of service in multi-matrix system bus

A multi-matrix bus system is disclosed that provides proactive quality of service (qos) by propagating, as soon as possible through an arbitration node in a network transfer request path, a highest priority value coming from an upstream arbitration node or master that has a current bus request pending at the arbitration node. The bus system ensures that any last downstream arbitration node knows at any time which is the highest priority request pending in the network transfer request path from the masters that are competing to share the bus layer switches and arbitration nodes in the network transfer request path.. ...
