summary

Claims a 1.2–2.5× throughput boost for inter-datacenter bulk transfers by converting multicasts into algebraic mixes using linear network coding and running as an overlay so it does not change TCP or routing. It adds a custom hop-by-hop hardware backpressure to keep asynchronous arrivals and finite buffers from overflowing, implements coding/decoding at data centers, and evaluates on geo-distributed AWS testbeds (Internet2 and B4 topologies) against single-path, multipath and Steiner baselines.
