Injection Time Planning: Making CQF Practical in Time-Sensitive Networking

IEEE Conference on Computer Communications, 2020
Time-Aware Shaper (TAS) is a core mechanism to guarantee the deterministic transmission for periodic time-sensitive flows in Time-Sensitive Networking (TSN). The generic TAS requires complex configurations for the Gate Control List (GCL) attached to each

An Efficient Heuristic CQF Scheduling in Time-Sensitive Networking

IEEE Transactions on Industrial Informatics
IEEE 802.1Qch, also known as cyclic queuing and forwarding (CQF) shaper, enhanced the dynamic and flexible behavior of time-sensitive networking. Schedulability of the CQF is one of the major research fields used to improve system performance.

Towards Fine-Grained CQF Scheduling for TSN with Temporal Conflict Resolution

International Conference on Parallel and Distributed Systems
Time-Sensitive Networking (TSN) with Cyclic Queuing and Forwarding (CQF) enables deterministic communication in distributed cyber-physical systems. However, existing CQF schedulers model the timeslot as the minimum unit and ignore intra-timeslot dynamics;

Deterministic Flow Delivery via Routing-Scheduling Co-Optimization in Multi-Queue CQF

Global Communications Conference
Mission-critical applications require deterministic services for coexisting periodic and bursty flows. While the original cyclic queuing and forwarding (CQF) bounds delay via a dual-queue ping-pong buffering mechanism, its rigid architecture suffers from
