Draw a diagram of a TCP 3-way handshake between a web server at 192.168.1.5 and a client at 192.168.1.25, then draw a diagram of the following communication over the newly-opened TCP connection: the client sends a request composed of 1 KB of data, and the server responds with 3 KB of data. Assume a 1500 byte MSS. Ignore payload padding. Do not do pipelining (set your congestion window to 1) -- only one packet in flight at a time, please. Include TCP sequence numbers, acknowledgment numbers, and flags in your diagram. Don't draw TCP or IP headers -- just give the sequence numbers and the flags (e.g. SYN, ACK, etc.). Do not worry about closing the connection after you are done. Your diagram should look a lot like Figure 3.31 in the book, but with flags in addition to sequence numbers and acknowledgment numbers.
