Evgeny	4556f327c2	1	4 months ago
Evgeny	1f4fe37fe5	proxy: rename + simplify + backpressure - tcp_proxy/remote_proxy → tcp_proxy_client/tcp_proxy_server - Все proxy файлы перенесены в src/proxy/ - Конфиг: [tcp_proxy]→[tcp_proxy_client], [remote_proxy]→[tcp_proxy_server] - Убран subcmd CONNECTED (0x02) — клиент шлёт DATA сразу после CONNECT - Backpressure: etcp_router_waiter_register/cancel через ll_queue threshold waiter - Клиент: recv_cb send fail → tx_buf+waiter, не tcp_recved() (окно lwIP=0) - Сервер: read_cb send fail → pause_buf+waiter, пауза read_id - CLOSE/ERROR отправляется только после drain всех очередей - Fail: conn не найден/closed → send ERROR вместо CLOSE/silent drop - PROTOCOL.md: полная архитектура с диаграммами состояний и потоков	4 months ago

Evgeny	61fee27478	congestion: burst-based BW measurement + adaptive inflight (slow start/cong avoidance/loss response) New features: - get_time_us() in lib/u_async.c/h for µs-precision timing - Burst measurement (ETCP_SECTION_MEAS_TS 0x07, MEAS_RESP 0x08, FILLER 0x09) - 12 MTU packets sent at line rate, receiver measures inter-packet gaps - Burst triggered when link saturated + min 500ms interval - Result: measured BW -> bandwidth for shaper, burst_target_bdp for window cap - 3-phase adaptive inflight in link_stats_timer_cb: - Slow start: windows doubles each RTT, exits on loss/RTT spike/threshold - Congestion avoidance: additive increase, proportional RTT shrink, multiplicative loss shrink - Burst target cap: inflight_lim <= burst_target_bdp * 1.1 - Dynamic optimal_inflight = sum(link->inflight_lim_bytes), recalculated on change - Adaptive win_timebase = rtt/2 (was hardcoded 10ms) Fixes: - dummynet.c: shaper formula fixed (80000 -> 80) - dummynet.c: queue_data_put call fixed (3 args -> 2) - etcp.c: SIZE ERROR format string (missing log_name argument) - etcp_request_pkt: FILLER leaves room for PAYLOAD overhead Tests: - test_etcp_congestion.c: single-threaded, 5-phase BW/delay/loss test - sender + receiver + dummynet in one uasync - CSV metrics output every 100ms - All 29 existing tests pass	5 months ago
