IP networks today require massive effort to conﬁgure and manage. Ethernet is vastly simpler to manage, but does not scale beyond small local area networks. This paper describes an alternative network architecture called SEATTLE that achieves the best of both worlds: The scalability of IP combined with the simplicity of Ethernet. SEATTLE provides plug-and-play functionality via ﬂat addressing, while ensuring scalability and efﬁciency through shortest-path routing and hash-based resolution of host information. In contrast to previous work on identity-based routing, SEATTLE ensures path predictability and stability, and simpliﬁes network management. We performed a simulation study driven by realworld trafﬁc traces and network topologies, and used Emulab to evaluate a prototype of our design based on the Click and XORP open-source routing platforms. Our experiments show that SEATTLE efﬁciently handles network failures and host mobility, while reducing control overhead and stat...
