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.
