Part 1: Network upgrade Proposal
Organization details
Wiakato District Educational Institute is located in New Zealand. It is an educational
institute with about 1000 users of the network both teaching staff, non-teaching staff, and
students. On daily basis the educational Institute supports over 500 users. The educational
Institute have five remote campuses which are located across New Zealand. Current the main
branch is located in a four floors building. Due to population growth the educational Institute is
currently upgrading to have a fifth floor which will handle the increasing number of students in
the institution. In addition, the educational Institute carries high student records. In addition, the
educational Institute has several workstations but the main one are the customer care desk, staff
room, the educational Institute lab, the finance unit which is also known as the billing office, and
administrative office. The country requires every educational Institute to be compliant with the
current IEEE guidelines and due to this the institution has employed email protection and data
encryption which they view it as a means of protecting the institution sensitive information. The
education institution also handles online classes to their students
Educational Institute goals
 Increase educational Institute staff productivity: This will automatically be measured by
the how long an employee takes to deliver a certain target and how many minutes or the
duration it takes serve an online student. The current time that it takes to serve a client is
4 minutes which is a result of the poor network design

 Reduce the educational Institute operational efficiencies: The current educational
Institute network availability is 7.4 hours per month. The project network availability is 3
hours per month
 Reduce the educational Institute operational costs: This is currently being measured of
TCO which is currently three million per year and the projected cost will be 1.5 million
dollars (AM Fremont, 2013).
Technical educational Institute goals
 Improve educational Institute network security: Replacing all the hubs with Optical
network splitters. To the sub-stations all the hubs will be replaced by the managed
switches and complying with the HIPPA requirements to protect student data. In addition,
is creating VLAN for the data centers so as to prevent access of the critical student data.
 Improving the educational Institute network speed: The current PSTN lines will be
replaced with fiber optical cables. Optical fiber carries both audio, video, data, and voice
at the same time.
Description of the existing technology
The current educational Institute network uses old model switches from various
manufactures. From analysis they comply with the current IEEE standards although it depends
on when they were purchased. Specifically the educational Institute has five workstations i.e.
class rooms, staff room, the finance unit, administrative unit, and the educational Institute
computer lab. Each of these workstations have sub-stations and the administrative office. The
educational Institute has installed a firewall which they use as a means of preventing
unauthorized access from what one would refer to as PSTN connection into the educational
Institute network. Third, the educational Institute has implemented a cat 5 cable with an internet
