摘要	Emerging time-sensitive applications in Wide Area Network (WAN) put forward urgent demands for deterministic Quality of Service (QoS), which cannot be satisfied by traditional networks. Deterministic Networking (DetNet) is designed to achieve deterministic transmission in Layer-3 networks. Based on the Cycle Specified Queuing and Forwarding (CSQF) mechanism, it has been able to provide bounded latency and jitter for time- sensitive flows. However, packets may experience unnecessary queuing delay when transmitted with CSQF, which will further affect their end-to-end latency. In this paper, the Cyclic Fast Queuing and Forwarding (CFQF) mechanism is proposed to address the problem. It sends packets meeting transmission conditions in advance according to their arrival time, reducing their queuing delay by several cycles while maintaining the same jitter's bound. To deploy CFQF in WAN, we present the FastDet architecture that enables Faster Deterministic transmission and offers differentiated services for different types of flows. The simulation results demonstrate that FastDet can provide bounded end-to-end latency and jitter for time-sensitive flows with lower queuing delay than the existing deterministic networking architecture, and the QoS of flows with other types can also be guaranteed to some extent, indicating its feasibility to be applied in WAN.
