For the past few years, ITS has worked to improve the foundation for all U-M 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 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 for dual distribution layer (DLs) routers. Now that the work to build the new core network is complete, the following step is to connect in-building networks to the newly-upgraded core network. The transition requires replacing the distribution layer router (DL) in each building.
This project to connect buildings to the New Core Network is estimated to take about 3 fiscal years to complete. ITS has drafted a timeline to connect close to 200 buildings across these three years to the new core network. 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 fit within capacity limits. ITS prioritized buildings based on the following data:
- End-of-life date of the existing DL
- Known bandwidth bottlenecks
- Imminent research needs
