Dear Folks, My name is Yifei Yuan, and I am a researcher at Carnegie Mellon University. I am working on a research project related to testing network configurations, where I want to survey the problems that are encountered when conducting testing on networks. I would very much appreciate it, if you could participate this survey, which can be found in the following link: http://cmu.ca1.qualtrics.com/jfe/form/SV_bvE1oBeO9NI5r5X The survey is anonymous, and it would take no more than 5 mins to finish up all questions. Your participation is voluntary with no compensation, and you must be at least 18 years of age to complete the survey. Thanks, Yifei Yuan Postdoctoral researcher ECE, CMU
