Description

TCP is the one of the most overlooked concept of a network engineer. This is one of the most important protocol which should be understood by every Network Engineer to do his or her work effectively. Many people failed interview if they do not have complete picture of TCP. This is one of the most detailed video course ever built on TCP protocol. We will take very simple example from our daily life to talk each and every aspect of TCP protocol. Let’s learn Layer-4 in detail. We are going to cover following topics in this course.

  1. Connection Establishment: Sequence number, Acknowledgement, Segment, TCP headers and flags, TCP 3 Way Handshake and lets see all in Wireshark

  2. Flow Control: Buffering, Data Transfer, Windowing, Opening and Closing of Windows, Connection Termination, silly window syndrome, Nagle’s algorithm. Some examples.

  3. Error Control: Acknowledgement, duplicate AC’s, Ack rules, Checksum, Our-of-Order segments, Retransmission. Some scenarios.

  4. Congestion Control, Timers and Options: TCP Slow start, Congestion Windows, congestion policy, RTO, Persistence Timer, Selective Acknowledgements

  5. Let’s combine all the puzzles and create our TCP header. Believe me you do not need to memorize any field of TCP header because at this point you understand why behind every field. You can create TCP header from scratch.

Who this course is for:
