It works by scheduling bandwidth probes between pairs of hosts, wherein each pairwise exchange reveals the upload constraint of one participant. Using the abstraction of bandwidth tournaments, unresolved hosts are successively paired with each other until every peer knows its upload bandwidth. [&hellip;]"}
