TCP - A story about hope, (pkg) loss && the missing link
summary
Explains how TCP actually guarantees ordered delivery: the three‑way handshake with sequence and ACK arithmetic, the TCP header fields that carry sequence/ack/window values, flow control and a receive window now capped at 1 gigabyte, and congestion control starting from an initial cwnd of 10 that probes capacity, uses loss as feedback and applies algorithms like PRR; shows head‑of‑line blocking forcing retransmits and clarifies what TCP provides and what it inherently cannot fix.
