1. Assume the following parameters for Go-Back-N a) N 3 b) Round Trip Time (RTT)10 ms c) Retransmission Timeout period 40 ms d) Segment Size: 1200 bytes. Suppose that Bob sends 7 segments, numbere1 through 7, to Alice using the Go-Back-N mechanism. Suppose that Segment 3 and Segment 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. 2. Assume the following parameters for Selective Repeat: a) N 3 b) Round Trip Time (RTT)10 ms c) Retransmission Timeout period 40 ms d) Segment Size: 1200 bytes Suppose that Bob sends 6 segments, numbered 1 through 6, to Alice using Selective Repeat. Suppose that Segment 3 gets lost the first time Bob sends it to Alice, but reaches 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. 3. Consider a TCP connection with the following parameters: a) Initial ssthresh-8 segments b) Round Trip Time (RTT) - 10 milliseconds c) Timeout period - 40 milliseconds d) Segment size: 1500 bytes The TCP connection was used to transfer 16 segments. While sending the segments, Segment 4 was lost the first time it was sent. There were no other segment losses. Consider that out-of-order segments at the receiver are buffered. What is the average throughput obtained in sending all the segments (in bytes/sec)? Draw a diagram to show your work in detail. 1.
