SDRN : réseau maillé temps réel dynamique défini par logiciel

Florian Greff 1, 2
Abstract : We are studying a new kind of embedded real-time mesh network. Mesh networking of the components of embedded systems reconciles their real-time constraints with the new application needs in terms of bandwidth and tight interactions. The plurality of communication paths results in increased flexibility, resilience, scalability and load balancing characteristics. However, this requires the ability to dynamically allocate network resource with respect to the needs of running applications. Our approach is to allow applications to make online real-time flow resource requests and consequently allot network resources according to these requirements. To this end, we have designed the Software-Defined Real-time Networking (SDRN) architecture. It addresses flow isolation, timing analysis, routing, fault tolerance, as well as the interfaces with the application layer and the lower layers of the system. It also allows any module to be replaced without interfering with the remainder of the architecture. It has been validated via an implementation on an in-silicon RapidIO platform. This thesis describes our research on the SDRN architecture. It also proposes an original method for experimenting on embedded networks, ERICA. The ERICA framework automatically generates all what is needed to conduct a network experiment in a selected environment (such as a simulator or a testbed), with both physical and simulated aspects. Hence, it allows the researcher to perform a high-level thinking of the whole experimentation process and to reuse applications and experiment designs from an experimentation stack to another
