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 7,300 miles (11,748 km) of fiber, 5,600 wireless access points, and 2,500 switches that provide on-campus wired connectivity. The Institute also owns and operates the MIT Regional Optical Network—a 2,500-mile (4,023 km) optical ring connecting researchers in Boston, New York City, and about 10 other locations across the Northeast. In addition, MIT has 10-gigabit dedicated connections to Internet 2, Akamai, Amazon, VMware, and the Energy Sciences Network, and a 100-gigabit connection to the CERN Large Hadron Collider.

Mobility. MIT is a fully wireless campus. The MIT Mobile App, for iPhone and Android, connects users to the MIT map, shuttles, news, and events.

Cloud-based Infrastructure and Services. About half of MIT’s managed servers have been transitioned to a Cloud environment. In addition, the MIT community has access to several enterprise Cloud applications, including CrashPlan, Dropbox, Duo Security, and LastPass.

Kerberos and Athena. Kerberos was originally developed at MIT to secure network services on Athena, MIT’s main academic computing environment, and is now a widely adopted protocol for network authentication. Athena provides academic software, courseware, and public computing facilities, primarily to students.

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 central IT Service Desk handles approximately 25,000 telephone calls, 9,500 in-person requests and 55,000 emails per year. Distributed Support Teams provide desk-side support to 42 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.
