Appendix 9: Network Infrastructure
Building a network infrastructure is most easily
described by equating it to the building of our highways, roads and streets.
The part of our infrastructure
that we compare to highways would be our network backbone. Our campus
telecommunications backbone consists of a cable containing thirty-six fiber
optic strands connecting
each of the thirty-two campus buildings to a central hub. Twenty-four
of these fibers (24 of the 36) only have the ability to handle current bandwidth
needs but the remaining twelve have bandwidth limitations far exceeding
and foreseeable technology requirements.
- When the fiber was installed only six of the thirty-six fibers were terminated
(fiber optic connectors attached to the fibers and connected to a patch bay)
for each building. To provide the equivalent of an interstate highway that
we will need to support the traffic many of the applications being proposed
require, we will need to significantly increase the quantity and type of
fibers terminated. We propose that an additional six of the lower bandwidth
and six of the higher bandwidth fibers for each building be terminated.
telecommunications wiring within our buildings, going to offices and classrooms,
could be compared to roads and streets, meaning that these pathways get us
from the interstates and highways to other locations. One of our first priorities
should be to insure that every office and classroom has at least one network
connection capable of supporting current software applications. The Network
Engineering Group has recently completed a study, which indicates that there
are 682 offices and classrooms needing to be wired and an additional 146,
which have been wired but have not been funded for connection into the network.
currently have over 2,200 network connections using twisted pair copper cable
to connect offices, classrooms and labs to the telecommunication backbone.
- Network equipment must provide adequate bandwidth to accomplish the higher
level applications from anywhere at anytime. This includes video, multimedia,
GIS applications and various intensive bandwidth applications.
the campus telecommunications infrastructure does not have redundant paths.
This means that if a fiber is cut between two buildings the telecommunications
to those building will cease to function until repairs can be made. This
could take one to two days depending of the location of the cut. We need
secondary routes of fiber to critical buildings on campus such as Administrative
Services, ECC and Centennial Hall.
- We need to ensure that all network design
and architecture will facilitate smooth upgrade paths.
- We advise the creation
of a Bandwidth Management and Network Use team to provide a clearinghouse
for inquiries on adequacy of bandwidth to support applications.
An example of this would be when KVSC wanted to provide audio programming
over the network utilizing Real Audio which is an Internet application for
audio programming. They assumed that there was insufficient bandwidth available.
If they had known whom to contact, a test of network utilization could have
been performed to determine whether there was sufficient bandwidth available
for their applicaion.
