Formal Worst-Case Timing Analysis Of Ethernet Tsn'S Burst-Limiting Shaper

Daniel Thiele, Rolf Ernst
2016 Zenodo  
We present a formal timing analysis for BLS in order to compute worst-case latency bounds.  ...  One of these traffic shapers is the burst-limiting shaper (BLS). In this paper, we evaluate whether BLS is able to fulfill these strict timing requirements.  ...  We presented a formal analysis approach to derive worstcase timing guarantees for the burst-limiting shaper (BLS) of the upcoming Ethernet TSN standard.  ...

Formal worst-case timing analysis of Ethernet TSN's time-aware and peristaltic shapers

Daniel Thiele, Rolf Ernst, Jonas Diemer
2015 2015 IEEE Vehicular Networking Conference (VNC)  
We present a formal timing analysis, which is a key requirement for the adoption of Ethernet in safety-critical real-time systems, to derive worst-case latency bounds for each shaper.  ...  In this paper, we consider TSN's time-aware and peristaltic shapers and evaluate whether these shapers are able to fulfill these strict timing requirements.  ...  A first attempt of a formal timing analysis of TSN's traffic shapers (including the burst-limiting shaper) has been presented in [7] .  ...

Zero Jitter for Deterministic Networks without Time-synchronization

Jinoo Joung, Juhyeok Kwon
2021 IEEE Access  
Note that for the C&C FA the max burst size is equal to the twenty times of the max packet length. Similar arguments can be applied to the worst case analysis for the audio or video flows.  ...  The worst packet's service time is at the last of the slot. At the 4 th node, the slot can be as short as the twenty C flows' burst transmission time.  ...

Regulating Scheduler (RSC): A Novel Solution for IEEE 802.1 Time Sensitive Network (TSN)

Jinoo Joung
2019 Electronics  
Attaching a regulator in front of a scheduler to limit the maximum burst is considered as a viable solution.  ...  Flow based schedulers suggested in a traditional integrated services (IntServ) framework are O(N) or O(log N), where N is the number of flows in the scheduler, which can grow to tens of thousands in a  ...  Intuitively, DRR* gives the worst case DRR service to i in terms of packet service finish time. Now we will come back to the nw-DRR scheduler.  ...

A Survey on Network Calculus Tools for Network Infrastructure in Real-time Systems

Boyang Zhou, Isaac Howenstine, Siraphob Limprapaipong, Liang Cheng
2020 IEEE Access  
CATS focuses on the timing analysis of real-time tasks. It can provide both the best and the worst-case response times of tasks after giving the task pattern and the computational resources.  ...  Thus, we do not use CATS to estimate the worst-case delay bound in this paper. G. WOPANETS WOPANets is short for WOrst-case Performance Analysis of Embedded Networks [27] .  ...  His research focuses on CPS/IoT (Cyber-Physical Systems/Internet of Things) and is geared toward enabling intelligent infrastructure based on the convergence of real-time sensing, model-driven data analytics  ...

The Virtual Bus: A Network Architecture Designed to Support Modular-Redundant Distributed Periodic Real-Time Control Systems [article]

Mark Turner, University, The Australian National
The Virtual Bus network architecture uses physical layer switching and a combination of space- and time-division multiplexing to link segments of a partial mesh network together on schedule to temporarily  ...  The Virtual Bus architecture achieves deterministic delivery times for time-sensitive traffic over multi-hop partial mesh networks by employing true line-speed switching; delays of around 15ns at each  ...  Acknowledgements Acknowledging that this is a research exercise, rather than the design and implementation of an industrial network, my goals in terms of the network size and capacity to be supported by  ...
