Assume the following parameters for Go-Back-N: a) N = 4 b) Round Trip Time (RTT) = 10 ms c) Timeout period = 40 ms d) Segment Size = 1100 bytes. Suppose that Bob sends 12 segments, numbered 1 through 12, to Alice using the Go-Back-N mechanism. Suppose that Segment 6 and Segment 11 are lost the first time the segments are sent to Alice, but reach Alice correctly when retransmitted. Apart from the above, there were no other segment losses. What is the average throughput obtained in sending all segments (in bytes/sec)? Draw a diagram to show your work in detail.
