IaaS Providers need next-generation virtualized networks, providing large-scale multi-tenancy services and meeting new requirements in terms of efficiency and availability. The main limitation of current network architectures mainly comes from inadequate design standards.

In this presentation, we present a TRILL based multi-tenant network architecture for virtualized data center networks. This architecture allows the best of both layers (bridging and routing), thus building a large-scale layer-2 network while ensuring scalability, efficiency, fault-tolerance and simplified management.

This enables also the creation of large numbers of logical networks within a virtualized data center.

The kernel part of our solution is currently developped in the Linux kernel.
