Computing on Campus

The computing environment at MIT supports an impressive array of information technologies and resources.

MITnet. MIT’s network infrastructure in the Cambridge/Boston area is made up of more than 7,500 miles (12,070 km) of fiber, over 6,900 wireless access points, and 4,000 switches that provide on-campus wired connectivity. The MIT Kendall Wi-Fi network covers approximately 1,000,000 square feet (92,903 m2) of outdoor space in the Kendall Square area and surrounding neighborhoods. The MIT Regional Optical Network—a 2,500-mile (4,203-km) optical ring—connects the MIT network to New York City and about 10 other locations, including the Massachusetts Green High Performance Computing Center. MIT’s 100-gigabit backbone supports connections to Internet2 and the Energy Sciences Network, which in turn provides access to the CERN Large Hadron Collider. In addition, MIT has 10-gigabit dedicated connections to Amazon, Comcast, and Apple, as well as dual redundant 10-gigabit links to the commodity internet.

Mobility. MIT is a fully wireless campus. The MIT Mobile App connects the community to the people directory; the campus map; information about shuttles, dining, and events; and more.

Cloud-based Infrastructure and Services. Information Systems and Technology (IS&T) provides managed servers to the MIT community through a hybrid cloud computing environment. In addition, the community has access to several enterprise cloud applications, including CrashPlan, Dropbox, Duo Security, and LastPass.

Athena and Kerberos. Athena is MIT’s academic computing environment, which powers computing clusters (labs) with a mix of Linux and macOS workstations, private workstations, remote access servers, and personal machines throughout campus. Kerberos was originally developed at MIT to secure network services on Athena, and is now a widely adopted protocol for network authentication.

Systems. Stellar/LMOD, MIT’s course management system, currently houses 1,000 sites containing course materials, assignments, and other resources. WebSIS, the student information system, provides access to personal records, course information, and scheduling.

Support. The IS&T Service Desk handles approximately 25,000 telephone calls, 10,000 in-person requests, and 55,000 emails per year. Distributed Support Teams provide desk-side support to 53 departments, labs, and centers. An extensive Knowledge Base draws on the cumulative IT expertise at MIT to deliver close to 10,000 self-help articles to the community.
