      "text": "## How TCP congestion control works\n\nTCP congestion control keeps the Internet stable by letting each connection estimate how much traffic the path can carry without overloading routers or links. Unlike flow control, which protects the receiver\u2019s buffer, congestion control reacts to **network** overload: dropped packets, growing queues, or explicit signals from routers.\n\nMost implementations use a **congestion window** (`cwnd`), a cap on how many unacknowledged segments may be in flight. The sender probes capacity by increasing `cwnd` while acknowledgments arrive on time; when it infers congestion, it shrinks the window.\n\n**Slow start** begins cautiously: `cwnd` grows exponentially (often doubling each RTT) until a threshold or until loss occurs\u2014fast discovery of spare bandwidth on a new path. After that, **congestion avoidance** usually increases `cwnd` more slowly (classically one segment per RTT), so growth stays near the sustainable rate.\n\n**Loss-based** algorithms (Reno, CUBIC on many Linux systems) treat packet loss as congestion: on timeout they often reset `cwnd` to one segment; on duplicate ACKs they **fast retransmit** and **fast recover**, cutting the window but avoiding a full restart. That recovers quickly from isolated drops while backing off when the path is saturated.\n\n**Delay-based** and hybrid schemes (Vegas, BBR) watch RTT or bottleneck rate. Rising delay can mean queues are filling before drops happen, so they can ease sending earlier. **ECN** lets routers mark packets instead of dropping; TCP treats marks like loss and reduces rate, easing queue buildup.\n\nEach connection independently adapts, so many flows sharing a link tend toward a fair share of capacity\u2014TCP\u2019s distributed feedback loop is what keeps aggregate traffic from persistently exceeding what routers and links can handle.\n\n---\n\n**File:** [notes.md](<synthetic-project>) \u2014 60 fruit entries, each with a one-sentence description.\n\n**`seq 1 400`:** the last number printed is **400**."
