U-M Net Building Connection Upgrade Project

For the past few years, ITS has worked to improve the foundation for all U-M Net network and telecom systems, enabling them to be more robust. The substantial expansion and enhancement of our outside fiber optic plant in particular will enable high reliability and increasingly high performance for decades to come. The U-M Net Core Network Upgrade project contributed to this by enabling any building on campus to connect to the network at 100 Gbps, with many buildings connected at 2x100 Gbps or 4x100 Gbps with dual network switches. With the work to build the new core network completed, the current step is to connect each in-building network to the newly upgraded core network. The transition requires replacing the first network switch in each building (the Distribution Layer switch). 

This project to connect buildings to the new core network is estimated to take about three years to complete. ITS has drafted a timeline to connect close to 200 buildings across these three years. This timeline can be found on the Building Status page of this site. The proposed schedule reflects both a desire to complete the project on schedule and to fit within capacity limits.

ITS prioritized buildings based on the following information:

  • End-of-life date of the existing first network switch
  • Known bandwidth bottlenecks
  • Imminent research needs
