1. A method comprising: enforcing a one-way message order mechanism for messages having independent message classes sent between first and second interconnects in an interconnect network, each of the first and second interconnects comprising a separate plurality of wiring pathways and coupled to separate pluralities of nodes and employing separate electronic pathways for messages belonging to the first and second message classes, wherein a message in a first message class is ensured to arrive at a destination node prior to a related message of a second message class sent to the destination node by employing a buffered mechanism between the first and second interconnects, wherein the buffered mechanism includes separate buffered paths corresponding to the first and second message classes and is configured to hold a message of a second message class received at the buffered mechanism in a later cycle than messages of a first class are received at the buffered mechanism and delay the message of the second message class from being sent out of the buffered mechanism until after the messages of the first class are sent out and received at their next destination.
