Conception et Ingénierie de Réseaux Nouvelle Génération Orientés Ethernet

Abstract : The increase in individual and professional customer expectations, as well as the fast technological evolutions, are leading to the design of the Next Generation Internet (NGI). Network optimization allows operators to efficiently deliver high-quality services at reduced costs. Due to the pre-eminence of Ethernet technologies at the customer premises and in the access network segment, and due to its low cost, Ethernet is a natural candidate to serve as the technology of choice of the NGI. In the metropolitan network segment, efforts have led to specifying Ethernet flavors which allow mapping client traffic into Virtual LANs. In this thesis, we investigate how to efficiently assign these VLANs to the Spanning Trees generated by Ethernet's Spanning Tree Protocol, since this is currently the only way to perform traffic-engineering and network optimization in this network segment. In the core network segment, several initiatives aim at turning Ethernet into a GMPLS-controlled connection-oriented technology (such as Layer 2 LSPs and PBB-TE). In this thesis, a new type of connection for packet- and frame- based, connection-oriented and GMPLS-controlled technologies is introduced and studied: the bus-LSP. Both in single-layer and in multi-layer networks, it provides the operator with significant cost reduction. We provide quantification of this reduction, as well as engineering methods for efficiently deploying bus-LSPs. We also detail the control plane protocols extensions needed to manage these bus-LSPs.
