about

nx_udp_tracker.nx -- BitTorrent UDP tracker protocol (BEP-15), bits-up. module: nishi-core.torrent.udp_tracker depends: nx_syscalls.nx capability: CORE_COMPUTE wired_status: FULLY_WIRED The dominant tracker transport (BEP-15, Olaf van der Spek 2008): ~618 bytes / 4 packets for 50 peers vs HTTP's ~1206 / 10 -- half the bytes, no TCP setup. Two-step: connect (get a connection_id) then announce (get peers). Pure build/parse here (KAT'd, deterministic); the UDP socket round-trip reuses the net stack + nx_net_governor pacing. Big-endian wire; magic protocol_id 0x41727101980.
