1) Why does the Segment Sequence Number remain unchanged (indicated by a horizontal line in the graphs) with every drop in the congestion window?
2) Analyze the graph that compares the Segment Sequence numbers of the three scenarios. Why does the Drop_NoFast scenario have the slowest growth in sequence numbers?
3) In the Drop_NoFast scenario, obtain the overlaid graph that compares Sent Segment Sequence Number with Received Segment ACK Number for Server_West. Explain the graph.
Hint:
- Make sure to assign all values to the Capture mode of the Received
Segment ACK Number statistic.
4) Create another scenario as a duplicate of the Drop_Fast scenario. Name the new scenario Q4_Drop_Fast_Buffer. In the new scenario, edit the attributes of the Client_East node and assign 65535 to its Receiver Buffer (bytes) attribute (one of the TCP Parameters). Generate a graph that shows how the Congestion Window Size (bytes) of Server_West gets affected by the increase in the receiver buffer (compare the congestion window size graph from the Drop_Fast scenario with the corresponding graph from the_Drop_Fast_Buffer scenario.)
