Simulation of Instability in Time-Sensitive Networks with Regulators and Imperfect Clocks

Regulators are used in time-sensitive networks in order to reshape traffic reducing the burstiness generated by the aggregation systems within the network. Regulators, in terms of the IEEE TSN group are defined as Asynchronous Traffic Shaping or what in th ...

Exploring manycore architectures for next-generation HPC systems through the MANGO approach

David Atienza Alonso, Marina Zapater Sancho, Arman Iranfar, Simone Libutti

The Horizon 2020 MANGO project aims at exploring deeply heterogeneous accelerators for use in High Performance Computing systems running multiple applications with different Quality of Service (QoS) levels. The main goal of the project is to exploit custom ...

Tackling the Bottleneck of Delay Tables in 3D Ultrasound Imaging

Giovanni De Micheli, Luca Benini, Federico Angiolini, Marcel Arditi, Aya Mohamed Naguib Ahmed Ibrahim

3D ultrasound imaging is quickly becoming a refer- ence technique for high-quality, accurate, expressive diagnostic medical imaging. Unfortunately, its computation requirements are huge and, today, demand expensive, power-hungry, bulky processing resources ...

Designing Best Effort Networks-on-Chip to Meet Hard Latency Constraints

Giovanni De Micheli, Luca Benini, Srinivasan Murali, Ciprian Seiculescu, Hamid Sarbazi-Azad, Dara Rahmati

Many classes of applications require Quality of Service (QoS) guarantees from the system interconnect. In Networks-on-Chip (NoC) QoS guarantees usually translate into bandwidth and latency constraints for the traffic flows and require hardware support in t ...

An Analytical Model for the Contention Access Period of the Slotted IEEE 802.15.4 with Service Differentiation

Giovanni De Micheli, Nadia Khaled, Eugène David Ngangue Ndih

The IEEE 802.15.4 standard is poised to become the global standard for low data rate, low energy consumption wireless sensor networks (WSN). By assigning the same sets of contention access parameters for all data frames and nodes, the contention access per ...

Mapping and Physical Planning of Networks-on-Chip Architectures with Quality-of-Service Guarantees

Giovanni De Micheli, Luca Benini, Srinivasan Murali

Networks on Chips (NoCs) have evolved as the communication design paradigm of future Systems on Chips (SoCs). In this work we target the NoC design of complex SoCs with heterogeneous processor/memory cores, providing Quality-of-Service (QoS) for the applic ...

Quantitative Modelling and Comparison of Communication Schemes to Guarantee Quality-of-Service in Networks-on-Chip

Paolo Ienne, Mehmet Harmanci, Yusuf Leblebici

We address the quantitative comparison of two basic connection schemes for on-chip communication, connection-oriented and connection-less, regarding their enforcement of a defined Quality-of-Service for the communication. For such comparison, we have built ...

Packet scale rate guarantee for non-FIFO nodes

Jean-Yves Le Boudec

Packet Scale Rate Guarantee (PSRG) is a generic node model which underlies the definition of Expedited Forwarding (EF) proposed in the context of Internet Differentiated Services. For the case of FIFO nodes, PSRG is equivalent to the well-understood concep ...

Delay Jitter Bounds and Packet Scale Rate Guarantee for Expedited Forwarding

Jean-Yves Le Boudec

We consider the definition of the Expedited Forwarding Per-Hop Behaviour (EF PHB) as given in RFC 2598\ \cite{rfc2598}, and its impact on worst case end-to-end delay jitter. On one hand, the definition in RFC 2598 can be used to predict extremely low end-t ...

Theories and Models for Internet Quality of Service

Jean-Yves Le Boudec

We survey recent advances in theories and models for Internet Quality of Service (QoS). We start with the theory of network calculus, which lays the foundation for support of deterministic performance guarantees in networks, and illustrate its applications ...
