      "text": "## TCP congestion control\n\nTCP congestion control lets many hosts share networks without collapsing throughput under load. Each connection maintains a **congestion window (cwnd)**\u2014how much unacknowledged data it may have in flight. The sender also respects the receiver\u2019s **receive window**. The effective send rate is bounded by the smaller of the two and by round-trip time (RTT).\n\nClassic TCP (Reno and cousins) alternates **slow start** and **congestion avoidance**. After idle or loss, cwnd often starts small (sometimes one segment). In slow start, each ACK that advances the window typically grows cwnd by about one segment, so the window ramps quickly until it hits **ssthresh** or loss appears. Above ssthresh, congestion avoidance adds roughly one segment per RTT (often via additive increase on ACKs), probing for more capacity without overshooting as aggressively.\n\n**Loss** is treated as a congestion signal (buffer overflow or wireless corruption, depending on era and algorithm). On timeout, many variants slash cwnd sharply and re-enter slow start. On three duplicate ACKs, **fast retransmit** resends a missing segment without waiting for the timer; **fast recovery** holds cwnd higher than after a timeout, then eases back toward congestion avoidance.\n\nNewer designs react to more than drops. **CUBIC** (common on Linux) uses a cubic function of time since the last loss to grow cwnd quickly when far below the prior peak and cautiously near it. **BBR** models the path\u2019s **bottleneck bandwidth** and **minimum RTT**, pacing sends to match capacity while limiting queue buildup instead of using packet loss as the primary signal.\n\nAcross flavors, the pattern is the same: **probe** for available capacity, **back off** when the path is saturated, and **fairness** emerges because every flow that sees the same signals tends to converge toward a balanced share of the bottleneck.\n\n---\n\n## [notes.md](<synthetic-project>)\n\nCreated at [<synthetic-project>) with 60 one-line fruit entries (plus a short title).\n\n## `seq 1 400`\n\nThe last number printed is **400**."
