Yggdrasil builds end-to-end encrypted networks with IPv6. Beyond the
similarities with cjdns is a different routing algorithm. This
globally-agreed spanning tree uses greedy routing in a metric space.
Back-pressure routing techniques allow advanced link aggregation bonding
on per-stream basis.  In turn, a single stream will span across multiple
network interfaces simultaneously with much greater throughput.
