TCP Reliability:

Consider the following scenario. (Yes, the same as in the midterm, but now it is TCP instead of GBN or SR. This is also an idealized TCP, (section 3.5.4), in that you should ignore congestion (3.6) and flow control (3.5.5).) For simplicity, assume that each TCP packet contains only 1Byte of data, and that the initial TCP sequence number is 1. All parameters are the same as in the midterm problem: 4 segments to send, window size = 3 bytes (ignore transmission delay = 1 ms for one segment and 0 for the ACK, and one-way propagation delay = 2.5ms Suppose that Packet No. 2 is lost and no other packet is lost. The beginning of the space-time TCP congestion and flow control), timeout-8ms diagram is provided below . Fill out the rest of the diagrams until all 4 packets are sent and acknowledged. Show all packets (transmissions, retransmissions and acknowledgements), their sequence numbers and the times they were sent/received . What is the total time until all 4 packets are successfully acknowledged at the server? 5ms 8 Consider the following scenario.
