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, 6,100 wireless access points, and 4,000 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. MIT’s 100-gigabit connection to Internet2 links the Institute to 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 VMware.

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. Over 85% 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.

Athena and Kerberos. Athena is MIT’s main academic computing environment, which powers computing clusters (labs), 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 central IT 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 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.
