You pick up your iPhone while waiting in line at a coffee shop. You google a not-so-famous actor, get linked to a Wikipedia entry listing his recent movies and popular YouTube clips of several of them. You check out user reviews on Amazon and pick one, download that movie on BitTorrent or stream that in Netflix. But suddenly the WiFi logo on your phone is gone and you're on 3G. Video quality starts to degrade, but you don't know if it's the server getting crowded or the Internet is congested somewhere. In any case, it costs you $10 per Gigabyte, and you decide to stop watching the movie, and instead multitask between sending tweets and calling your friend on Skype, while songs stream from iCloud to your phone. You're happy with the call quality, but get a little irritated when you see there're no new followers on Twitter. You may wonder how they all kind of work, and why sometimes they don't. Take a look at the list of 20 questions below. Each question is selected not just for its relevance to our daily lives, but also for the core concepts in the field of networking illustrated by its answers. This course is about formulating and answering these 20 questions.
New feature: This course will launch the Grand Challenge Homework (GCH) program. Throughout the course, there will be about 10 open-ended, project-like challenges (in social and technological network engineering) provided to all the enrolled students. Associated with GCH is a Industry and Investor Partners (IIP) program. About 10 leading US companies and venture capitalists in the networking industry have agreed to screen the finalists selected by the teaching staff, and then explore opportunities with the selected students to turn their ideas and prototypes into new products and companies. You pour your creativity and energy in this course, we will help create career-changing opportunities for you. The IIP companies associated with this course range from the world-renowned Bell Labs to a startup founded by the father of DSL, and from Silicon Valley VC's like USVP to university-spinoff specialist firms like Osage Partners.
