Data Network & Internet


Backbone Network

UMnet Backbone

The UMnet Backbone is one of three University of Michigan backbone data networks that connect a building's local area networks (LANs) to the Internet.

On-Campus Backbone Connections

U-M Ann Arbor Campus buildings and data centers are connected to the UMnet Backbone through Distribution Layer switches.

Off-Campus Backbone Connections

Off-campus locations of U-M departments and units can connect to the UMnet Backbone in various ways.

U-M Backbone Interconnect Network (UMBIN)

The UMBIN interconnects the three main campus backbone networks to the state network (Merit) and beyond to the Internet and to private educational and research networks.

U-M Virtual Firewall

The U-M Virtual Firewall Service is a network security service available to academic and administrative units on the Ann Arbor campus.

NOTE: The Virtual Firewall is scheduled to be replaced with a network Intrusion Prevention System (IPS) in 2014. Existing virtual firewalls will be maintained and supported, but ITS will no longer make investments in the service or expand its coverage. Capacity for additional subscriptions is extremely limited. Please contact ITS Information and Infrastructure Assurance (via the ITS Service Center) for assistance. More information will be provided as it becomes available.
