Dear Sharvanath Pathak:My name is Xiaoqing Sun,a junior at BUPT(BeiJing University of Post and Telecommunication)in China,majoring in information engineering.I'm writing to ask for some advice about the ModNet.I got started with "Computer Network" at the begining of this semester and my teacher assigned me to study your paper 《ModNet: A Modular Approach to Network Extension》 two weeks ago. I found it's very interesting and meaningful ,thus I want to try it in person. I downloaded the source code from GitHub andsetup the kernel successfully,but I don't know how to test its performance.I'm wondering if you can tell me the concrete steps to make a performance comparison, specifically, how to switch variants,make traffic statistics and finally work out Figure 10"The bitrate of video segments for a synthetic bandwitdth trace for all the three variants:adaptive,truncate and yank" in your paper.Thank you for reading my letter patiently,and I'll be appreciate if you can give me some advice.Looking forward to your reply!Yours sincerelyXiaoqing Sun
