Titre1: DAS: An Efficient NoC Router for Mixed-Criticality Real-Time Systems
Titre2: Mixed-Criticality System and Network-on-Chip: A Dual Task and Flow Model
Mixed-Criticality Systems are real-time systems characterized by two or more distinct levels of criticality. In MCS, it is imperative that high-critical ﬂows meet their deadlines while low-critical ﬂows can tolerate some delays. Sharing resources between ﬂows in Network-On-Chip (NoC) can lead to different unpredictable latencies and subsequently complicate the implementation of MCS in many-core architectures. This talk will present ongoing work at Lab-STICC to enforce mixed-criticality requirements deployed over NoCs. We propose task and communication models to investigate their schedulability. Furthermore, a specific NoC router design is proposed and validated.
Over the past decade, a wide-ranging collection of network functions in middleboxes has been used to accommodate the needs of network users. Although the use of general-purpose processors has been shown to be feasible for this purpose, the serial nature of microprocessors limits network functional virtualization (NFV) performance. In this talk, we describe a new heterogeneous hardware-software approach to NFV construction that provides scalability and programmability, while supporting significant hardware-level parallelism and reconfiguration. Our computing platform uses both field-programmable gate arrays (FPGA) and microprocessors to implement numerous NFV operations that can be dynamically customized to specific network flow needs. Traffic management and hardware reconfiguration functions are performed by a global coordinator that allows for the rapid sharing of middlebox state and continuous evaluation of network function needs. To evaluate our approach, a series of software tools and NFV modules have been implemented. Our system is shown to be scalable for collections of network functions exceeding one million shared states.
Russell Tessier has worked in the research area of reconfigurable computing for the past 25 years. In addition to being a professor, he is the Associate Dean of Graduate Studies for the UMass College of Engineering. His current research interests include security for field-programmable gate arrays, networks-on-chip, and embedded systems.
Le séminaire poster permet de réunir les collègues de toute l'équipe et d'échanger autour d'un poster, déjà présenté lors d'une manifestation scientifique ou créé pour l'occasion.
Le séminaire poster du 4 avril a réuni 19 posters. Chaque poster fait l'objet d'un "teaser", présenté devant l'assemblé et sont disponibles dans le fichier joint.Download : Teasers du séminaire poster MOCS du 4 avril 2017 (8.89 Mo)
