  1. multiplexing and demultiplexing and how it is used - perhaps http server and handling multiple requests at the same time can be used to illustrate this in some way.

    • dealing with lost/corrupt data
    • maintaining order, if needed
    • timeouts, ACKS, NACKS, etc
Changed:

<
  1. Performance - sliding windows, selective ACK, go back N, sequence numbers
>
>
    • sequence numbers
  1. Performance with respect to retransmission scenarios - sliding windows, selective ACK, go back N, sequence numbers
