Inside campus libraries and dormitory rooms, thousands of students connect to the Internet not only to study with online systems like Blackboard but also to watch movies and TV shows on Netflix. Computers, smartphones, wireless printers, tablets, iPods, Xboxes, handheld gaming systems, e-readers, smart TVs, Blu-ray players--students now bring an arsenal of devices to connect to campus networks, often using multiple gadgets simultaneously. And campus networks, as well as some information-technology staff members, are buckling under the pressure. In a report released last March by the Association of Information Communications Technology Professionals in Higher Education, about 76 percent of chief information officers surveyed said they were worried about increasing bandwidth use. In the same report, 77 percent listed an increasing number of mobile devices as a major concern about future network strain. Video- and music-streaming Web sites like YouTube, Spotify, and--possibly the biggest headache of them all--Netflix are now consuming large amounts of bandwidth. And that is exacerbated by the number of devices all using those services. Administrations must decide how to balance academic uses of the network with recreational uses. That can be a tricky combination to figure out, especially for students who live on the campus.
