Abstract
Conventional wisdom has held that routing protocols can not achieve both scalability and high availability. Despite scaling rather well, today's Internet routing system does not react quickly to changing network conditions. Overlay networks, on the other hand, can respond quickly to changing network conditions, but their reliance on aggressive probing does not scale to large topologies. This project presents a resilient layered routing architecture called UFO (Underlay Friendly to Overlays), which achieves the best of both worlds by providing router support for overlay routing mechanisms. UFO comprises two changes to existing routers: (i) data-plane support for deflection packets at the behest of the overlay and (ii) explicit notification about significant changes in network conditions. We present these two mechanisms, and demonstrate how they facilitate the scalable deployment of overlay routing mechanisms at the network layer. Prototype is implemented based on PL-VINI platform, with preliminary evaluation results.
