CST 311 - Week 3

This week we covered the transport layer, specifically we learned more about TCP and UDP protocols. First, the team assignment had us work together in order to create two separate client-server applications that used a UDP protocol. I worked on the client portion of part one, where I created a py file that set a timeout value for lost packets and calculated various RTT values from each successful ping. The lab portion of this week's assignment covered TCP and congestion control more in depth. For this lab, we were expected to plot data showing the time and cwnd data points. As was discussed in the readings, slow start, segment/packet loss and congestion avoidance could all be plotted and identified within these graphs. Overall, I learned a lot from this module and am looking ahead to the midterm that will be taking place in just a few days!
