OVERVIEW OF INTERNETWORKING
Scope of wired and wireless network design
The scope of development of the network for Calasanz school is to provide internet access
to the students and prepare them for future digital education and helping them to get familiar with E
learning. A powerful wireless network is needed to be developed that would help the user to
connect their own devices with the school network. A cost effective network solution is needed to
be developed for Calasanz school that should be easy to deploy and manage such that less number
of staffs are available for the management of the network. The area of coverage of the wireless
signal is needed to be identified such that the wireless network covers a major area of the school.
The network is needed to be divided for allowing access and service to the different group of users
and separate login credentials are needed to be used for allowing the access to different services
needed by them. The device that can be deployed for management of the needs is identified and
installed for enabling easier modification and managing future upgrades. The enthusiasm of the
users are needed to be improved for engaging the in learning and provide maximum benefit to the
user.
Challenges
The main challenges for the development of the wireless network solution is to identify the
service that are needed by the different levels of users in the school. The selection of the
appropriate technology for the development of a cost effective network solution is important
because there are limited number of staffs available for maintenance of the network. A centralized
network solution is needed to be developed and cover the two primary and the high school
buildings. A proper area is needed to be selected or the installation of the wireless access point and
nearby there should not be any other source that causing interference and affect the performance of
the wireless signal. Redundant device is needed to be used such that if any of the device fails the
secondary device can be used for reaching the destination address by the user.
User centric design Concept
The network is designed following the user centric design concept and principles such that
usability of the network increases and the network is designed following the needs of the user.
Different research design techniques are used for increasing the redundancy of the network device
connecting the network device via multiple link such that the network is response time is reduced.
Multiple stage problem solving process is used for ensuring that the structure of the network is kept
simple and the constraint can be exploited for aligning the network with the needs of the user.

Outcomes
The main outcomes of the networking project is to design a wired and wireless network
solution and gaining knowledge about the routing and switching technology and the elements that
are needed for the development of the network framework. It also helps in identifying the network
device that are required for the network development and rapidly deploy the solution without
effecting the teaching schedule of the school. The deployment of the network would also help to
create a strong and stable coverage of the WiFi signal and support education in multiple ways. The
student can find educational resources from any location in the school while connecting with the
wireless signal via different type of wireless devices such as smartphones, laptops, ipads and other
handheld devices. The connectivity issues that are currently faced by the user are eliminated with
the development of the network framework. The network is developed by configuring the switches
with VTP server and the layer 2 devices connected in the network are configured with vtp client such
that the VLAN information configured in the core switch is automatically transferred to the devices.

OVERVIEW OF INTERNETWORKING
The need of training and maintenance for the management of the network platform is needed to be
eliminated such that performance of the network is improved and enables a simplified management
and control on the network.
Limitations
The main limitation identified for the development of the wireless network solution for
Calasanz School is to develop a centralized wireless network solution and management of the access
of the users to the wireless network. For the improvement of the security of the network solution
the wireless access point is needed to be secured with encryption algorithm such that the
unauthorised access can be restricted. The network is needed to be monitored from a central
location for identifying the flow of data packet and eliminate the risk of accessing the sensitive
information residing in the school server.
Conclusion
From the above report it can be concluded that the analysis and development of the
wireless network solution for Calasanz School would help the student and teachers for improving the
learning environment. The technology that can be used for the development of the network at a
minimal cost is identified by researching on the different type of network devices and hardware. A
design of the network is created and the number of department of the school is analysed for dividing
the network with multiple VLAN and enable access to different types of service for the different
users connected in the network. The wireless network device is selected based on the coverage area
and speed that it can deliver such that the users can access the online information form the internet
at a minimal time.
