Summary
The purpose of this report is to assess and summarize the requirements of the network and discuss
the logical network design with the help of a logical network diagram of the entire network of
Calasanz School which includes the two main buildings. After providing the requirements summary,
the logical design gets described after the logical network diagram. The report explains how the
network design benefits Calasanz School in terms of connectivity, performance, convenience and
security. For connectivity, it is discussed how the network of Calasanz school meets the
requirements and with what devices, also mentioning the model, manufacturer and count. Based on
the connectivity, the performance estimates of the network are derived. Then the multi-pronged
security gets discussed along with how different access levels are provided to the academic and
administrative staff members as well as how access levels is further segmented among students and
teachers or staff. Following that the report talks about the convenience of implementing the
network and ends with observations in concluding notes.

Introduction
This report looks to summarize and assess the network requirements and discuss the logical
network design by making use of a logical network diagram for the overall network of Calasanz
School detailing network structure of both the two buildings [3]. After the requirements summary I
provided, the logical design is described following illustration of the logical network diagram. The
report elaborates how the network design benefits Calasanz School based on the parameters -
connectivity, performance, convenience and security. For connectivity, it is discussed how the
network of Calasanz school meets the requirements and with what devices, also mentioning the
model, manufacturer and count. Based on the connectivity, the performance estimates of the
network are derived. Then the multi-pronged security gets discussed along with how different access
levels are provided to the academic and administrative staff members as well as how access levels is
further segmented among students and teachers or staff. Following that the report talks about the
convenience of implementing the network and ends with observations in concluding notes.
Network Design
Scope
1. School Buildings need to be able to give wireless connections to all 33 classrooms.
2. Each of the six departments of the school must benefit from wireless networks.
3. Both campuses and classrooms should be accessing wireless.
Challenges
a. Setup of wireless network to premises of school campuses premises can prove
challenging against installing in of classrooms for absence of power jacks.
b. All buildings require several switches for ensuring all wireless access points in each of
the 33 classrooms as also premises is connectable.
c. User login Verification credentials will be requiring significant resources in servers.
Requirements Summary
The two buildings of Calasanz School contains a total of 33 rooms for accomodating more
than 1290 students and 83 teachers. There are 18 classrooms in the high school building and 15
classrooms in the primary school building. Network connections to both these buildings need to be
provided from the main router with the help of a suitable network switch from a leading
manufacturer. Wireless connections in both the buildings must be provided by the appropriate
wireless access points built by a trusted brand.

Connectivity and Performance
Here it can be clearly seen how the main router of the Calasanz School in Colombia accesses
internet from the respective Internet Service Providers or ISPs who distribute internet connections in
several packages based on bandwidth and usage limits [5]. This network connection is further
broken into two sub networks for providing dedicated network connections to the devices of either
of the two buildings with the help of TL-SF1048 switches from TP-Link [4]. This enables to reduce
traffic on a single network thereby increasing network performance by efficiently maintaining the
allocated bandwidth [10]. If problems, network faults or even security risks arise in the network of
either of the building, the particular risk can be isolated to that section of the network only, thus
preventing the total shutdown of network services in both buildings. The wireless connections being
provided by EAP120 wireless access points built by TP-Link on rooftops of the buildings provide
wireless network access to the campuses and classrooms of both primary and high school buildings
[6]. Fast and reliable wireless network connections are ensured by means of installation of a high
quality chipset for strong signals both inside and outside of Calasanz classrooms. This is the
Qualcomm Atheros 560 Mhz chipset which enables network access for both 1000 users [7]. A
tentative strength of students and teachers of Calasanz School can be:
1290 + 83 = 1373
Users supported by Qualcomm Atheros chipset – 1000
Since two of these chipsets are in use for the wireless access points of both the buildings, maximum
supported users double to 2000. Therefore, one can safely say that the network infrastructure set up
at Calasanz School, Colombia handily meets the network usage requirements. The two servers

located in each of the buildings are used for performing network administrative purposes as well as
hosting the captive web portal and running authentication processes for verifying user credentials.
Security
A multi layered security policy help protect Calasanz School from security risks, data theft,
exploits and other cyber security attacks. The login verification process ensures that different access
levels are granted to the teachers and staff from what is granted for students [8]. This authentication
processing is run by a radius server located in each building so that one of them is always available if
faults arise in the other one (DeKok and Korhonen 2019). The network access is further divided
between academic members and administrative members by the use of two VLANs in each building
[9]. These are the ‘User’ VLAN and the ‘Admin’ VLAN. Connection interfaces of the switch with the
main router, the server and the wireless access point make use of VLAN 3 (Admin) while
workstations for academic work make use of VLAN 2 (User).
Convenience
As the EAP120 wireless access point supports POE or Power over Ethernet, it becomes very
easy and flexible to deploy these devices in almost anywhere in the School campus [2]. This
prevented the school from making extra investments in setting up infrastructure for installing these
devices. The device comes with a free to use network management software that offers real time
network monitoring and centralized configuration of the entire network.
Conclusion
To conclude, it is observed that the report successfully assesses and summarizes the
requirements of Calasanz network and discuss the logical network design with the help of a logical
network diagram the entire network including the two main buildings. After providing the
requirements summary, the logical design gets described after the logical network diagram. The
report explains how the network design benefits Calasanz School in terms of connectivity,
performance, convenience and security. For connectivity, it is discussed how the network of
Calasanz school meets the requirements and with what devices, also mentioning the model,
manufacturer and count. Based on the connectivity, the performance estimates of the network are
derived. Then the multi-pronged security gets discussed along with how different access levels are
provided to the academic and administrative staff members as well as how access levels is further
segmented among students and teachers or staff. Following that the report talks about the
convenience of implementing the network owing to the benefits of wireless devices chosen.
