Abstract: The emerging latency-sensitive services such as smart grid and tactile internet require deterministic network performance including deterministic end-to-end latency, latency jitter and bounded packet loss rate. To empower standard Ethernet with such capability, we provide a deterministic forwarding system named DLCC with end-to-end congestion control and queue management available at common hardwares to provide bounded delay over Internet. Meanwhile, DLCC provides a per-hop delay correction scheme to minimize delay variation under dynamic scenarios. Compared with other schemes, DLCC effectively reduces the delay jitter by up to 90% and is able to quickly converge to the required end-to-end delay.
