> 6. There is no such thing as a TCP packet Because the software abstraction is a stream of bytes; and it's up to the application to decide where the "packets" begin and end. For example, I might write to a TCP socket: 100 bytes, 50 bytes, and then 125 bytes. BUT, the receiver could get: A single event with 275 bytes. Or it could get an event with 75 bytes and then an event with 200 bytes. Or it could get 11 events of 25 bytes. > 5. There is a such thing as a TCP packet This one I struggle with. I think the author is talking about connection set up, acking, and connection teardown.
