Solving “Big Data” problems requires bridging massive quantities of compute, memory, and storage, which requires a very high bandwidth network. Recently proposed direct connect networks like HyperX [1] and Flattened Butterfly [20] offer large capacity through paths of varying lengths between servers, and are highly cost effective for common data center workloads. However data center deployments are...
Today's mobile networks prevent users from freely accessing all available networks. Instead, seamless network composition could present a win-win situation for both users and operators. Users can gain better quality of service with more resources to choose from, while each individual operator can provision lesser bandwidth since resources can be shared during times of peak demand. In this paper, we...
We show that complex (scale-free) network topologies naturally emerge from hyperbolic metric spaces. Hyperbolic geometry facilitates maximally efficient greedy forwarding in these networks. Greedy forwarding is topology-oblivious. Nevertheless, greedy packets find their destinations with 100% probability following almost optimal shortest paths. This remarkable efficiency sustains even in highly dynamic...
