Patent ID: 7016363

Claim:
An interconnect structure comprising; a plurality of interconnected nodes including distinct nodes A, B, C, and D; data interconnect lines AB 1 and AB 2 coupled from the node A to the node B for sending data from the node A to the node B; data interconnect lines CD 1 and CD 2 coupled from the node C to the node D for sending data from the node C to the node D; a data interconnect line AD coupled from the node A to the node D for sending data from the node A to the node D; means for detecting a condition at the node C; means for sending a control signal CS from the node C to the node A, the control signal being determined at least in part by the condition at the node C; and means for sending a message M arriving at the node A to the node B or the node D on a data interconnect line selected from among the data interconnect lines AB 1 , AB 2 , and AD depending at least partly on the control signal CS; wherein the condition at the node C, depending at least in part on quality of service of messages, if any, passing from the node C to the node D, manages sending of messages from the node A to the node D.
