Network: 2022 Maintenance

The Division of Technology Services is in the middle of a multi-year project that is replacing all of the fiber optic communication cable across campus. As part of the same project, we are upgrading all network communications gear in our communications rooms in each building to align with new physical and logical requirements. That new gear is physically different from the older gear and requires us to physically reconfigure more than 8,000 wired network connections and 1,400 wireless access points campus wide.

DoTS will use the summer months of 2022 to prepare the communications rooms for the new network connections to the new fiber optic cabling and for the new network gear that will begin to be installed in early 2023. The goal is to accomplish all of these changes before August 1, 2022.

There are numerous factors that affect the order and timing of each building. DoTS staff have tried to identify the shortest time frames required to complete the work for each building. There will be a wide range of impacts across all facilities. Some buildings will have a total network (wired and wireless) outage for much of the announced duration and in other buildings a single office may only have a short 5 minutes or less outage. We are unable to predict the impacts due to unknown variables that may occur with the work.

If you feel that the time frame for your building will have an unmitigable impact upon your program, please contact DoTS immediately. As stated, we need to accomplish these changes before August 1; the more time we have to realize a change in schedule, the better.

Scope of each building

  • We are referring to this project as "refactoring" of the communication rooms. We are focusing on a new standardized template for labeling, power management, patch cables and positioning of the gear. The outcome of this will be a reduced outage in academic year 2023 to cut over each building to the new network gear.

  • The last project (2014/2015) avoided re-cabling each communications room; each room has in some cases three decades of patch cable "rat's nests" to untangle. Each communications closet has grown one office or classroom remodel at a time over the last three decades.

  • The new switches have different physical installation requirements. In most cases this requires us to re-cable every communications room. We are taking the summer slow periods to move the old switches to where the new switches will be located. This will aid in a much faster replacement of switches when we move to the new gear.

  • Buildings range in the number of communication rooms from 1 (e.g. RDI) to 13 (e.g. Falcon Center) rooms in total.

  • Each room will take between 1 and 4 hours of work to "refactor" to the new standard.

  • CSH will have the south communications room completely overhauled and brought up to our current standard. Presently, it is just a used radio equipment cabinet bulging with network gear. This outage may be more sustained as it requires complete dismantling of the current infrastructure to move into new racks.

General scope of the project

  • Replace fiber optic cabling that was installed in the late 1980's and early 1990's for all main campus buildings. Project creates a redundant loop to two new central nodes positioned at each end of main campus. Also creates a new redundant loop to south campus creating a new ring to Campus Lab Farm, to Falcon Center and back to main campus.

  • Add additional capabilities at the Amphitheatre and the Intramurals complex.

  • Replace all existing switching gear on a scheduled life cycle; last major refresh was 2014/2015.

  • Create an all-new network topology design with new network hardware that will have "software defined networking" capabilities. This will allow us to implement "cloud like" security features at a much lower (detailed) level than we are capable of now.

  • Collapsing the wired, wireless and VPN platforms into a single secure system instead of three separate systems giving each use a single identity across any mode of connectivity.

  • Increase system to system security to aid in slowing attacks that propagate across the network, such as ransomware.
