Throttle and Preempt: A New Flow Control for Real-Time Communications in Wormhole Networks

In this paper, we study wormhole routed networks and their suitability for real-time traffic in a priority-driven paradigm. A traditional blocking flow control in wormhole routing may lead to a priority inversion in the sense that high priority packets are blocked by low priority packets for unlimited time. This uncon-trolled priority inv...More
