  1. 1 - Intro
  2. 2 - Pre-Requisites - background knowledge of TCP and UDP
  3. 3 - Twelve Ideas to understand TCP and the TCP Header
  4. 4 - Idea 1 - Sequence Numbers and Acknowledgement Numbers
  5. 5 - Idea 2 - Sequence & Acknowledgement Numbers are tracking BYTES sent and received
  6. 6 - Understanding Sequence Numbers and Acknowledgement Numbers
  7. 7 - Idea 3 - TCP Retransmission Timer
  8. 8 - Idea 4 - Delayed Acknowledgements - Acknowledgments are Cumulative
  9. 9 - Idea 5 - Window Size and Bytes in Flight
  10. 10 - Delayed ACKs vs Window Size
  11. 11 - Idea 6 - Window Size, TCP Headers and Flow Control
  12. 12 - Idea 7 - TCP is Bidirectional - both peers have SEQ# and ACK#
  13. 13 - Empty Acknowledgements, Duplicate Acks, TCP analysis, TCP troubleshooting
  14. 14 - Idea 8 - Initial Sequence Numbers ISNs are Random
  15. 15 - Idea 9 - TCP Three Way Handshake - SYN, SYN ACK, ACK
  16. 16 - 3-way Handshake, SYN flags, ACK Flags, and the TCP Header
  17. 17 - Initial Window Size is set in the three-way handshake
  18. 18 - SYN packets increase the Sequence Number -- The Phantom Byte
  19. 19 - ACK flag is turned on for all TCP segments, except the initial SYN
  20. 20 - Idea 10 - Two methods for TCP to close a connection - FIN and RST
  21. 21 - Idea 11 - FIN Flags and Four Way Connection Closure
  22. 22 - FIN Flags do not need to be sequential
  23. 23 - Phantom Byte inside the FIN and SYN Segments
  24. 24 - Idea 12 - RST Flags instantly terminate a TCP connection
  25. 25 - Want more? Help me blow up these videos and I'll create the full TCP Masterclass
  26. 26 - Networking - The Internet, the Cloud, and everything in between
