A Network Calculus Analysis of Asynchronous Mechanisms in Time-Sensitive Networks
Time-sensitive networks provide worst-case guarantees for applications in domains such as the automobile, automation, avionics, and the space industries. A violation of these guarantees can cause considerable financial loss and serious damage to human live ...
EPFL2023Reference tracking stochastic model predictive control over unreliable channels and bounded control actions
A stochastic model predictive control framework over unreliable Bernoulli communication channels, in the presence of unbounded process noise and under bounded control inputs, is presented for tracking a reference signal. The data losses in the control chan ...
2021Towards Continuous and Ambulatory Blood Pressure Monitoring: Methods for Efficient Data Acquisition for Pulse Transit Time Estimation
We developed a prototype for measuring physiological data for pulse transit time (PTT) estimation that will be used for ambulatory blood pressure (BP) monitoring. The device is comprised of an embedded system with multimodal sensors that streams high-throu ...
2020On Time Synchronization Issues in Time-Sensitive Networks with Regulators and Nonideal Clocks
Jean-Yves Le Boudec, Ludovic Bernard Gérard Thomas
Flow reshaping is used in time-sensitive networks (as in the context of IEEE TSN and IETF Detnet) in order to reduce burstiness inside the network and to support the computation of guaranteed latency bounds. This is performed using per-flow regulators (suc ...
Association for Computing Machinery2020On Cyclic Dependencies and Regulators in Time-Sensitive Networks
Jean-Yves Le Boudec, Ludovic Bernard Gérard Thomas
For time-sensitive networks, as in the context of IEEE TSN and IETF Detnet, cyclic dependencies are associated with certain fundamental properties such as improving availability and decreasing reconfiguration effort. Nevertheless, the existence of cyclic d ...

For time-sensitive networks, as in the context of IEEE TSN and IETF Detnet, cyclic dependencies are associated with certain fundamental properties such as improving availability and decreasing reconfiguration effort. Nevertheless, the existence of cyclic d ...
IEEE2019Destination buffer analysis for packets rejection obliteration in multi-channel networks
In this paper we study a multi-channel network, each station of which is equipped with a network interface that has a receiver buffer of multiple packets. In this way, each station is able to receive multiple packets per time instant. We adopt a synchronou ...
2019Flow control for Latency-Critical RPCs
Edouard Bugnion, Evangelos Marios Kogias
In today’s modern datacenters, the waiting time spent within a server’s queue is a major contributor of the end-to-end tail latency of μs-scale remote procedure calls. In traditional TCP, congestion control handles in-network congestion, while flow control ...
2018Latency and Backlog Bounds in Time-Sensitive Networking with Credit Based Shapers and Asynchronous Traffic Shaping
Jean-Yves Le Boudec, Eleni Stai, Ehsan Mohammadpour, Maaz Mashood Mohiuddin
We compute bounds on end-to-end worst-case latency and on nodal backlog size for a per-class deterministic network that implements Credit Based Shaper (CBS) and Asynchronous Traffic Shaping (ATS), as proposed by the Time-Sensitive Networking (TSN) standard ...
IEEE2018A Theory of Traffic Regulators for Deterministic Networks With Application to Interleaved Regulators
We introduce Pi-regulation, a new definition of traffic regulation which extends both the arrival curves of network calculus and Chang's max-plus g-regulation, and also includes new types of regulation, such as packet rate limitations. We provide a new exa ...
