Feasibility Study for a Statewide Higher Education Information Technology Network
State of Connecticut, September 18, 1996

Costing Model - Assumptions

  • This document addresses the costs associated with connecting 33 public higher education sites (5 CSU, 9 UCONN, 16 CCTC, Charter Oak, DHE, and The State Library) to a statewide network. Even though the ultimate goal of this network is to extend connectivity to K-12, libraries, private corporations, independent colleges and universities, etc., the costs associated with connecting these additional sites are not included here.
  • This section contains order of magnitude estimates. Accurate pricing requires a detailed network design and carrier negotiations. A detailed design, if performed by a third party consulting organization, could cost $50,000-$100,000.
  • Where possible, a single network demarcation point per institution has been costed out. In most instances, however, network points of presence are required at multiple sites within an institution. Connectivity to specific floors/rooms within an institution are outside the scope of this document, and therefore not addressed in the cost evaluations.
  • The maximum bandwidth available per technology has been costed out (e.g., T1 for Frame Relay, T3 for ATM, PRI for ISDN). Furthermore, the cost models assume any-to-any connectivity between network nodes (without accounting for extraordinary fault tolerance/redundancy requirements).
  • It is assumed that existing hardware cannot support connectivity to the new infrastructure. As a result, new hardware has been costed out at each site. (Carriers were unable to provide pricing for outsourced equipment/management services. Consequently, for costing purposes, it is assumed that all networking hardware is owned by the State of Connecticut.)
  • The existing wiring infrastructure at each site is adequate to support the new network. Consequently, recabling has not been costed out.
  • The costs put forth in this document assume a single implementation phase. In reality, these costs would be allocated over multiple phases.
