Multi-Stream Gate Control of Time Aware Shaper for High Link Utilization

2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021
Ultra-low latency (ULL) data transmission is essential for many network applications. The IEEE 802.1Qbv Time-Aware Shaper (TAS) is a typical mechanism for providing ULL data transmission in bridged networks. All TAS enabled nodes must be time-synchronized and their gate time schedule in the gate control list (GCL) must be pre-configured considering the

A Framework for Virtualizing Time-aware Shaper Using High Performance NFV

2020 25th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA), 2020
In this work, we discover the feasible methods of using Network Function Virtualization (NFV) to reduce the complexity and cost of implementing and deploying the Time- aware Shaper (TAS). TAS is one of the traffic shapers presented in the recent IEEE Time Sensitive Networks (TSN) standard for industrial Ethernet.

eTAS: Enhanced Time-Aware Shaper for Supporting Nonisochronous Emergency Traffic in Time-Sensitive Networks

IEEE Internet of Things Journal, 2022
To guarantee stringent real-time requirements of time-critical traffic in industrial systems, the IEEE time-sensitive networking (TSN) task group has standardized time-aware shaping (TAS) in IEEE 802.1Qbv, which schedules precise and periodic transmission times using pre-assigned traffic information.

Gate Shrunk Time Aware Shaper: Dynamic Shaping Control on White Box Switch

2018 23rd Opto-Electronics and Communications Conference (OECC), 2018
We report an experimental evaluation of a gate-shrunk time aware shaper implementing a software version on white-box switch. A 77.5%, 60.0%, and 20.0% shrinkage rate by employing the proposed GS-TAS are achieved.

Study on Affect of GCL of Time-Aware Shaper on QoS for IEEE802.1 TSN Networks

2020 IEEE 9th Global Conference on Consumer Electronics (GCCE), 2020
A time-triggered scheduling mechanism called Time-Aware Shaper (TAS) is one of IEEE802.1 Standards and has a parameter, which is called Gate Control List (GCL), to control for each class of stream or traffic. QoS will be degraded if the implementer of TAS does not use an appropriate value of the GCL. This paper studies the effect of the GCL on QoS over
