Saihu: A common interface of worst-case delay analysis tools for time-sensitive networks

Jean-Yves Le Boudec, Seyed Mohammadhossein Tabatabaee

Time-sensitive networks, as in the context of IEEE-TSN and IETF-Detnet, require bounds on worst-case delays. Various network analysis tools compute such bounds; these tools are based on different methods and provide delay bounds that are all valid but may ...

Computation of ultra-short-term prediction intervals of the power prosumption in active distribution networks

Jean-Yves Le Boudec, Mario Paolone, Fabrizio Sossan, Plouton Grammatikos

Microgrids and, in general, active distribution networks require ultra-short-term prediction, i.e., for subsecond time scales, for specific control decisions. Conventional forecasting methodologies are not effective at such time scales. To address this iss ...

Network-calculus service curves of the interleaved regulator

Jean-Yves Le Boudec

The interleaved regulator (implemented by IEEE TSN Asynchronous Traffic Shaping) is used in time-sensitive networks for reshaping the flows with per-flow contracts. When applied to an aggregate of flows that come from a FIFO system, an interleaved regulato ...

Network-Calculus Service Curves of the Interleaved Regulator

Jean-Yves Le Boudec, Ludovic Bernard Gérard Thomas

The interleaved regulator (implemented by IEEE TSN Asynchronous Traffic Shaping) is used in time-sensitive networks for reshaping the flows with per-flow contracts. When applied to an aggregate of flows that come from a FIFO system, an interleaved regulato ...

A Palm Calculus Approach to the Distribution of the Age of Information

Jean-Yves Le Boudec

A key metric to express the timeliness of status updates in latency-sensitive networked systems is the age of information (AoI), i.e., the time elapsed since the generation of the last received informative status message. This metric allows studying a numb ...

Quasi-Deterministic Burstiness Bound for Aggregate of Independent, Periodic Flows

Jean-Yves Le Boudec, Seyed Mohammadhossein Tabatabaee

Time-sensitive networks require timely and accurate monitoring of the status of the network. To achieve this, many devices send packets periodically, which are then aggregated and forwarded to the controller. Bounding the aggregate burstiness of the traffi ...

Configuration of Guard Band and Offsets in Cyclic Queuing and Forwarding

Jean-Yves Le Boudec

Cyclic Queuing and Forwarding (CQF) is a mechanism defined by IEEE TSN for providing low jitter in a deterministic network. CQF uses a common time cycle and two buffers per node output port: during one cycle incoming packets are stored in one buffer while ...

Worst-Case Delay Analysis of Time-Sensitive Networks With Deficit Round-Robin

Jean-Yves Le Boudec, Seyed Mohammadhossein Tabatabaee

In feed-forward time-sensitive networks with Deficit Round-Robin (DRR), worst-case delay bounds were obtained by combining Total Flow Analysis (TFA) with the strict service curve characterization of DRR by Tabatabaee et al. The latter is the best-known sin ...

Efficient and Accurate Handling of Periodic Flows in Time-Sensitive Networks

Jean-Yves Le Boudec, Seyed Mohammadhossein Tabatabaee

Total Flow Analysis (TFA) is a method for the worst-case analysis of time-sensitive networks. It uses service curve characterizations of the network nodes and arrival curves of flows at their sources; for tractability, the latter are often taken to be line ...

Design of cost functions for the real-time control of microgrids hosting distributed energy-storage systems

Jean-Yves Le Boudec, Mario Paolone, Plouton Grammatikos

The research of this paper is framed in the context of multi-layered, optimization-based approaches for microgrid control. Specifically, we focus on the design of real-time objectives that are typically proxies of long-term ones. Examples include tracking ...
