ROME: Routing on Metropolitan-Scale Ethernet

The authors present the architecture and protocols of ROME, a layer-2 network designed to be backwards compatible with Ethernet and scalable to tens of thousands of switches and millions of end hosts. ROME is based upon a recently developed geographic routing protocol, Greedy Distance Vector (GDV). Switches in ROME do not need any location information. Protocol design innovations in ROME include a stateless multicast protocol, a Delaunay DHT, as well as routing and host discovery protocols for a hierarchical network. ROME protocols do not use broadcast. Extensive experimental results from a packet-level event-driven simulator, in which ROME protocols are implemented in detail, show that ROME protocols are efficient and scalable to metropolitan size.
