about

nx_intl_h2h.nx -- INTERNATIONAL head-to-head: our pipelines vs the rival TRANSPORT CLASSES on the paths that matter to the family (operator 2026-07-02: "benchmark against other systems capabilities and speeds like telegram etc for international interactions as those will be key"). EXTENDS the proven nx_room_perf_measure harness (same frame-by-frame physics, same honesty rules) to FOUR grounded intercontinental profiles x FOUR transport classes: (A) OURS-LIVE TCP relay + JPEG: a lost segment head-of-line blocks (+1 RTT) -- today's wire. (B) OURS-TARGET RS-FEC(k=8,m=2) over datagram (nx_room_fec_relay, BUILT, unwired): <=m losses recovered in-flight, no retransmit. (C) RIVAL-UDP Telegram/Zoom/WhatsApp CALL class: UDP + concealment + low jitter buffer (MODELED from banked rival_telegram/rival_mtproto/conn_webrtc -- concealment counts as smooth, the GENEROUS reading for rivals). (D) RIVAL-TCPFB the SAME rivals behind hard NATs/firewalls: TCP relay fallback -- identical head-of-line physics to (A). International hotel/corp/mobile nets hit this a lot. Profiles (grounded conn_subcable/conn_rtt + the Minsk-Dallas 150ms already banked): P1 Texas<->Minsk 150ms/2% P2 Texas<->Kyiv 160ms/5% P3 Texas<->Manila 200ms/3% P4 intl mobile LTE 180ms/8% jitter+-40. Also computes OUR voice mouth-to-ear per profile with TODAY's 21ms capture framing. HONEST: simulated links + real mechanisms; rival classes are MODELED not live-captured -- the live-capture h2h stays on the BEHIND list. GREEN = measurement SOUND (controls hold), verdict printed honestly. Log -> knowledge/status/intl_h2h.log. expect_exit: 0 license_tier: ORIGINAL
