The University of Michigan Network (UMnet) has a backbone of multiple 10 Gigabit Ethernet (GbE) links between campuses and provides multiple 1GbE or 10GbE links to buildings.
- For a description and diagram of the campus backbone, see itcom.itd.umich.edu/backbone/.
- For information about acquiring a 10GbE connection, visit itcom.itd.umich.edu/backbone/10gbe.
UMnet has two 10GbE connections to the Merit Network, the state’s network, for commodity or general Internet traffic. Merit has multiple 10GE connections to Chicago and Cleveland, with multiple 10GE peerings with other research networks such as Internet2, ESnet and CIC OmniPOP.
Michigan Lambda Rail (MiLR) (pronounced “MY-lar”) is a very high-speed, special purpose, data network built jointly by the University of Michigan, Michigan State University, and Wayne State University, and operated by Merit. MiLR provides campus researchers low-cost, 10GE connections between the three university campuses and to national and international research and education (R&E) connection points.
Both Merit and MiLR have Points Of Presence (POP) where R&E networks interconnect and exchange traffic at:
- Northwestern University (commonly called “Starlight”), and
- in Chicago, where the Internet2 and the Energy Sciences Network (ESnet) POPs are located at 600 W. Chicago.
In addition to general purpose connections, U-M researchers have four 10GEs from U-M’s Ann Arbor campus to Chicago over MiLR that are used for research-specific traffic. They are currently used for large data set transfers for LHC Atlas Tier2 project and uncompressed high definition video collaboration for the School of Information. The MiLR equipment will support 40 and 100 GbE connections. This technology provides great potential for additional connections that will position the university for future CI opportunities.
MiLR also provides Dense Wave Division Multiplexing (DWDM) services, allowing multiple light frequencies to share a single fiber between the three member universities (U-M, MSU and Wayne State) and Chicago, where interconnections with other R&E and government networks are available. Such networks include:
- Energy Sciences Network (ESnet)
- Global Lambda Integrated Facility (GLIF)
- National Institutes of Health

U-M also has a connection to the DYNES Project (Internet2 ION service) for dynamic circuits to participating research institutions. This service has been driven by the Atlas Tier2 project, but will be available to all researchers on campus.
