With the implementation of the new ITS Communication Technology Funding Model for network core services in July 2012, it is now possible for the first time in over a decade to plan for life cycle refresh of the campus network hardware.

There are six categories of devices that comprise the hardware capital for the campus network (this excludes the physical layer infrastructure associated with inter-building fiber and within-building copper and fiber):

  • Core/backbone routers
  • Distribution layer switches (Tier 1 and Building Entrance Switches – BES)
  • Access layer switches (End-User Switches – EUS)
  • Wi-Fi (based on full deployment)
  • Data Center switches
  • Network services/mgmt. systems hardware

For the present three-year refresh plan, only the first three categories will be considered; network systems hardware can be included within the annual network operational budget, wi-fi was never included as a core service within the Comm Tech rate model, and the ITS data center switch infrastructure needs are a separate issue.

Based on industry values and discussions with other universities, the lifespan ranges that we have used in the rate model calculation and for planning purposes for these three categories are shown in the table.

Category Lifespan Actual Lifespan (years)
Core/Backbone Router 3–5 years 5
Distribution Layer (Tier1/BES) 5–7 years 6
Access Layer (EUS) 7–10 years 10
