Heuristiques de conception de topologies réseaux : application aux réseaux locaux industriels

Abstract : Industrial Ethernet is a controversial discussion topic mainly due to its non-determinism. Many researches focus on the improvement of Ethernet's capabilities to deliver the deterministic performance required by critical applications. Generally, that is obtained by modifying the Ethernet protocol or the traffic generated by the applications. Furthermore, the industrial context imposes a links redundancy in order to provide reliable architectures. That is why we propose to improve the switched Ethernet topology performances by optimizing the network organization at the level of the physical layer. Some graph partitioning techniques have been used in order to design optimized topologies which guarantee bounded maximum end to end delays. Two heuristics have been developed and adapted to this network design problem. The obtained results show the interest of the proposed method.
