Introduction
The Kudler Fine Foods is one the best fine food stores around. They have come a long way
in such a short period of time; However, Kudler has out grown the old network infrastructure and
is in dire need of an enterprise wide upgrade. The strategic goals of the enterprise network are to
introduce new technologies in data collection, company communication, and information
protection while providing the best data speeds and network access. This is very important
because if this is done correctly, this will increase revenue and reduce the costs of operation in all
the Kudler Fine Foods stores. The new network will bring Kudler Fine Foods back up to
technological speed while as the same time improving the way they keep track of inventory and
sales by using data mining techniques which will be collected and analyzed in real time.
Network Overview
After reviewing of the network at Kudler Fine Foods, the network topology that is being used
is the bus network. The bus network is set-up in such a way that all the network nodes are
connected via CAT5 to the bus or communication line. All of the sites in the corporation are
using the same configuration of workstations, servers, and standalone ups. All of the networks
have one way of communicating to the internet and that is by 56k modem. The bus network is
very cost effective to set-up, but it can very difficult to trouble shoot because if the backbone
goes down the entire network will have an outage. The other aspect of this network that is a pain
is that fact that if two systems are sending a signal, at the exact same time to one another the
network will have signal collision, meaning that both signals will drop. In order to prevent this
from happening (CSMA/CD) or carrier sense multiple access with collision detection will be

set-up. This in effect will put the network into a listen mode to prevent the collisions from taking
place.
Network Response time
One of the major goals is to improve the lack of response time and latency, which is currently
being experienced on the network due to the 56k modem’s installed at all the sites. This is a very
critical issue because it is very slow and if one modem’s goes down, there is no other means of
communication to the internet or other sites. The first problem of response times, latency, and
jitter that are being seen on the entire network are all related and are being caused by not only the
slow network speeds, but the out of date systems being used.
The response time is measured by the time that it takes for a system to respond to user input
command. This is happening because all the host systems at all sites are running Window 98 and
a Pentium II processor, which is over 10 years old. The latency and jitter issues that are being
seen over the network are directly related to the bandwidth available and “Jitter is the amount of
variation in latency/response time, in milliseconds” (What is jitter?, 2006). This is being caused
by the low bandwidth provided by the 56k modem, which can only receive up to 56,000 bps
slow speed (means slow response time). This is also being caused by the fact that all of the
servers on the Kudler network are running Windows NT with Pentium III processors. Once these
have been replace with new systems and a T1line which can receive up to 1.544 Mbps, 27 times
faster than the old modem, the response time, latency, and jitter will be significantly reduced.
This means that the network performance will be able to keep up with all the real time feeds
