Topic notes
GATE CS tests TCP across three primary areas: congestion control dynamics (window growth phases, timeout recovery, and round-by-round segment tracking), sequence number wrap-around time and bit-budget calculations against MSL, and connection lifecycle mechanics (3-way handshake flags, state transitions during active/passive close, and crash recovery with RST segments). Questions are balanced between computational NATs involving RTTs and discrete bit math, and conceptual MSQ/MCQs focusing on byte-stream mechanics, piggybacking, and RFC 793 protocol invariants.
