Computer Networking Lab Week 8
Hi again, this is Sohan and I am working in a computer networking lab this summer at Columbia University.
Once again, my routine this past week was essentially the same as the weeks prior; try to run the test on the Orbit-lab, process the .pcap files, and graph the results. This last time, however, after several attempts, I was finally able to obtain some data as the test bed did not give too many insurmountable issues. With this new data, I am currently trying to run the Python scripts and MATLAB script to complete the post-processing of this new data set. instead of processing and graphing previous data sets. Given that this is a new data set, the post-processing also poses issues as some of the nodes from the test bed cannot properly create .pcap files and thus the Python script cannot process them. My new challenges include trying to figure out which .pcap files are causing the issues and to further develop the script and make adjustments to it so that it can process the .pcap files smoothly without any errors arising.
Also, this past week, we had a lab meeting where all the Ph.D students had to present their recent work, and a few had to practice their presentations for their posters in some upcoming gatherings. The most intriguing, and the one I could probably understand the most, was one on cascade power failures and how to predict which power lines will go out depending on which line fails. Since Varun was at Bell Labs that day (since our project is in conjunction with Bell Labs), me and Josiah had to present in his place. All the other Ph.D provided very constructive criticism and offered other solution to more efficiently process the .pcap files such as eliminating certain steps, like storing the values in an excel file, that can be avoided entirely and save some time without altering anything whatsoever.
Lastly, since our lab is under rennovation, we are currently working in another work area. However, this past Friday, some workers came to put in some cable trays, can be used to pass wires through and create a mini network of sorts. Instead of it taking them one hour to finish as they said it would, it took them five. Instead, the five of us working in this area went into the kitchen area and watched a few episodes of Breaking Bad to pass the time - one of my favorite days on the job!

For that Python exception problem, use "try...except...":
