Netw310 Week 6 Lab Report

1. Looking at the above graph, write a short paragraph on what is happening here with the congestion window and the flight size? Based on the graph I believe that the congestion on the server starts around 5,000 bytes and continues to increase for the next 11 seconds of the transmission..

2. In the Results Browser, bring up the Global TCP statistics for Delay (sec) and Segment Delay sec). In a short paragraph, comment on the delay graph. A TCP connection continues to increase w until a segment loss occurs as TCP creates, an end to end, to the IEEE

3. Overlay the statistics for Client Received Segment Ack Number and Sent Segment Ack Number. Zoom until you see a definite separation and shapes as below. Write a short paragraph explaining why the client numbers are so different from the server numbers and a description of what is happening. As for the time-shift, that is caused by the fact that a packet is traveling across the network which takes time (even if it's only milliseconds). The server does not know in advance what the next ACK number is, it knows which segments it has already sent and will continue with the next blocks.

4. Given the configuration of the Packet Discarder, write a short paragraph explaining why the server’s Congestion Window size has this variation. Paste a copy of this window into your lab report. When finished, hide or delete the panel. The congestion window size could vary due to bandwidth variation, packet loss and jitter.
