Workshop presentation

The Real-Time Networks (RTN) 2017 is a satellite workshop of the 29th Euromicro Conference on Real-Time Systems (ECRTS 2017), the premier European venue for presenting research into the broad area of real-time and embedded systems.

The RTN workshop is the fifteenth in the series of workshops that started at the 2002 ECRTS conference. No edition took however place in 2015. To continue a new series of workshops, RTN 2017 focuses on the current technological challenges around real-time network infrastructures either between chips or on-chip (NoC). Besides, accepted papers will be published in SIGBED Review unless authors explicitly refuse in order to keep material for a later publication in a conference or journal.

The RTN workshop provides a relaxed forum for both industrial and academic participants to present and discuss new ideas, new research directions and to review current trends in the area of real-time networks and NoC. Schedule will provide significant time for discussions among the attendees.

The RTN workshop seeking regular research paper or position paper that should not exceed 6 pages. Areas of interest include, but are not limited to:
  • Real-time network on chips (NoC)
  • Real-time Software Defined Networks (SDN)
  • Real-time message scheduling and mapping over off and on-chip networks (TSN, Ethernet, CAN, FlexRay, NoC, etc.)
  • Real-time applications (automotive, aerospace, multimedia, etc.): implementation, experimentation and evaluation
  • Performance evaluation, simulation and modeling tools of real-time networks (automotive, aerospace, multimedia, etc.)
  • Networked embedded systems and sensors, cyber-physical systems, internet of things
  • Real-time network management and time synchronization
  • Wireless technologies and Sensor Networks (WSNs) and applications

Keynote talks
  • Priority-based Wormhole Networks-on-Chip: challenges and opportunities

    Speaker: Leandro Soares Indrusiak, University of York.

    Abstract: Wormhole switching is widely used in network-on-chip (NoC) architectures due to small buffering requirements on each network router, which in turn results in low area and energy overheads. This is of key importance in multi-core and many-core processors, as the area and energy share of the on-chip interconnect itself can reach up to 30% of the area and energy used by the whole processor. However, the nature of wormhole switching allows a single packet to simultaneously acquire multiple links as it traverses the network, which can make worst-case packet latencies hard to predict. This becomes particularly severe in large and highly congested networks, where complex interference patterns become the norm.

    Different link arbitration mechanisms can result in different worst-case latency prediction models, and recent research has addressed NoCs with TDM, round-robin and priority arbitration. In this talk, I will focus on priority-preemptive wormhole NoCs. I will give a detailed account of the architectural features that can support that type of arbitration in NoCs, and will review the latest research on analytical methods aimed at predicting worst-case packet latency over such networks. I will then show opportunities and advantages of using priority-preemptive NoCs in the domains of multi-mode, mixed-criticality and secure systems, where the trade-off between flexibility and predictability that is inherent to such networks can be fully exploited.

  • Advances in Time-Sensitive Networking

    Speaker: Lucia Lo Bello, University of Catania.

    Abstract: In many contexts, such as, industrial and automotive networks, for efficiency and cost reasons the time-sensitive traffic flows generated by applications requiring predictable transmission times, low latency and low jitter are mixed with flows originated from applications with less severe timing constraints. In these conditions, it is imperative to guarantee the timing behavior of time-sensitive traffic. The work within the IEEE 802.1 Time-Sensitive Networking (TSN) Task Group, which is part of the IEEE 802.1 Working Group, goes into this direction. The talk will review the TSN set of standards and address some of the defined mechanisms to provide deterministic services through IEEE 802 networks, i.e., guaranteed packet transport with bounded latency, low packet delay variation, and low packet loss.
