Summary
The objective of the study is about conducting an analysis and discussion on Calasanz School
network requirements and provide description of logical design of the school through
drawing the layout of both wired and wireless networks for the two main buildings of the
school with the help of a simulation tool. After giving the requirements summary, the logical
network design gets explained after the respective diagram. This report carries on to
mention what benefits Calasanz School get from the suggested design. Such benefits come
from the following aspects - performance, connectivity, security and convenience. The
performance of network depends considerably on how network components can be
connected with the rest or even the number of components involved. Then this report
focusses on how security is put in place through the network along with the conveniences of
using wireless connectivity. Thereafter the report ends by providing observations in the
concluding notes.

Introduction
The following report tries to conduct an analysis and discussion over Calasanz School
network requirements while providing description of logical design of the school through
drawing of the layout for both wired and wireless networks for the two main buildings of
the school with the help of a simulation tool. The report begins talking about scope and
challenges and after giving the requirements summary, the logical network design gets
explained with the respective diagram. This report carries on to mention what benefits
Calasanz School get from the suggested design. Such benefits come from the following
aspects - performance, connectivity, security and convenience. The performance of network
depends considerably on how network components can be connected with the rest or even
the number of components involved. Then this report focusses on how security is put in
place through the network along with the conveniences of using wireless connectivity.
Thereafter the report ends by providing observations in the concluding notes.
Network Analysis
Network Scope
 Campuses as well as the 33 classrooms of the school has to be provided wireless
network access.
 Rooms for every six departments in Calasanz School are to have wireless
connectivity.
 WLAN connectors to be placed such a way that both campuses and classrooms can
enjoy wireless connections.
Network Challenges
 Wireless connectivity on school campuses are usually very complex and expensive to
set up than say in classrooms due to the unavailability of power points.
 All buildings will be requiring several switches to make the wireless access points of
the 33 classrooms or outdoor environments stay connected.
 Authentication process of user credentials are resource hungry and specialized
server-based hardware and equipment are necessary.

Requirements Specifications Summary
Total classrooms that are present in each of the two main buildings of the School
amounts to 33. The 33 rooms can accommodate excess of 1290 students plus 83 teachers as
well as other staff of Calasanz School. The high school building comprises of 18 classrooms
and the primary school building is only able to host about 15 classrooms. The two of these
buildings are acquiring network accesses from the school’s core router via respective
network switches obtained from trusted brands [4]. Network connections for specific
devices of every user in the respective classroom or campus of both buildings needs to be
ensured with wireless connectivity [9].
Logical Design of Calasanz Network
Internet access is got from one of the Internet Service Providers (ISP) [2]. These ISPs
are always connected with internet which is only the worldwide physical interconnect
facilitating the World Wide Web (www) [3]. One among the two buildings receives the
internet access before providing the same to the other building directly with ethernet cables
[1]. These buildings relay access to network to intended users in form of wireless
connectivity.

Network Connectivity/Performance
It is explained in the logical diagram how ISPs can be connected to servers of the
networks over the internet. ISP provide access by routing the network for various users
including Calasanz School through different packages based upon bandwidth, usage capacity

and number of connections required. The router of Calasanz School thus connects to the
router of the ISP and routes the network connection received to switches (TL-SF1048) of
two buildings. These switches provide network connections to the wireless access points
(EAP120) installed in each of the 33 classrooms as well as several other areas of the
buildings so that wireless network access is available in campuses also [5]. Each access point
can serve more than 1000 users, therefore meeting requirements of 1300 students and 83
teachers is not even an issue. Thus the low traffic ensures reliable ping and network
bandwidth to all devices.
Network Security
The security in this network is provided by two main ways – (i) user credentials
verification and (ii) through setting up VLAN based networks. Verification of user credentials
happen when members of this school tries accessing captive web portal of Calasanz School
[7]. By verifying user credentials, different access levels to company data can be granted
amongst students and teachers or other staff members. The authentication process of this
login verification is carried out in the Radius servers [6]. Among staff members access levels
can be again narrowed down to departmental requirements. These are the Admin,
Academic, Human-Resource (HR), Finance, Sports and IT Support departments respectively.
The access to the overall network also gets segmented between the network administrators
and the rest of the users of the network with the help of VLANs [8]. These VLANs can be
configured in the two switches that are present in the two main buildings. This is because
VLANs can be used to have different rules and configurations for different set of users by
emulating multiple virtual networks within the same physical network.
Network Convenience
The wireless devices in the form of EAP120 is either connected to switches directly
with no additional power setup like when connected with POE (Power over Ethernet)
switches or even through traditional methods [10]. Thus it becomes flexible to configure
wireless access for campuses with no need of excess spending on complex higher grade
antennas as also physical infrastructure for supporting them. EAP120 also provides with a
network management software application that enables centralized configuration of the

network as well as real-time network monitoring. Tools like these are typically very
expensive and rarely distributed with competing wireless access points.
Conclusion
In conclusion the above report successfully conducts an analysis and discussion over
Calasanz School network requirements and elaborates the logical design of the school
through drawing of the layout for both wired and wireless networks for the two main
buildings of the school with the help of a simulation tool. It is observed that scope and
challenges of the network get their mention in the beginning and after the requirements
summary, the logical network design gets explained with the respective diagram. This report
carries on to mention what benefits Calasanz School get from the suggested design. Such
benefits come from the following aspects - performance, connectivity, security and
convenience. The performance of network depends considerably on how network
components can be connected with the rest or even the number of components involved.
Then this report focusses on how security is put in place through the network along with the
conveniences of using wireless connectivity.
