The TCP Handshake and State Machine

This generated surface maps a learner-facing curriculum unit to its canonical source routes.

Curriculum surface​

  • Open learner-facing unit
  • Curriculum path: content/curriculum/systems/semester-05-os-networking/module-05-network-protocols-sockets/concepts/cluster-03-tcp-and-udp/09-the-tcp-handshake-and-state-machine-primary.md
  • App: systems
  • Semester: semester-05-os-networking
  • Module: module-05-network-protocols-sockets
  • Unit kind: concept
  • Curation level: module_curated

Learning objectives​

  • Explain The TCP Handshake and State Machine across protocol layers instead of treating packets, sockets, and applications as disconnected topics.
  • Use The TCP Handshake and State Machine to predict system behavior in tools such as tcpdump, Wireshark, or socket-level code.
  • Use computer-networking, unix-network-programming to connect the learner explanation to packet traces, protocol state, and API behavior.

Prerequisites​

  • Comfort with file descriptors, blocking I/O, and reading system-level diagrams.

Source books​

  • computer-networking
  • unix-network-programming

External enrichment​

  • Beej's Guide to Network Programming (read_if_stuck) - Best reinforcement when learners need to connect protocol concepts to real socket programming practice.
  • man 2 socket (official_docs_companion) - Anchors the networking module in the actual system interface instead of staying purely conceptual.

Source-of-truth note​

This teaching unit is learner-facing guidance assembled from multiple canonical book routes. Use the listed source books as the primary conceptual spine for The TCP Handshake and State Machine, and treat outside material as supporting enrichment only.
