OVERVIEW OF INTERNETWORKING
Scope of network development
The developmental scope for the Calasanz school network is provision of internet access for the
students as well as prepare them in case of digital education. This will help in getting familiarity with E
learning concept. For this purpose, the wireless network needs to be powerful as this will enable users
to connect via school network to their individual devices. The network solution needs to be cost
effective in nature for this school which should be easily deployable as well as manage lesser number of
staff members is required for network management. The identification of network coverage area of this
wireless signal is required so that a wide area gets covered. Division of the network needs to be done so
that authorized access is only possible according to valid login credentials. Identification of the device
required for management is necessary as installation and further modification process becomes much
easier. The user’s enthusiasm needs to be properly channelized so that learning process could be
improved. This will result in maximum benefit to the customers.
Challenges
The primary challenges to develop this network is identification of services which is needed for
the different levels in school. Selecting an appropriate technology to develop a cost efficient network is
very important as there is limitation in the number of staff members available for network maintenance
purposes. A network solution which is centralized in nature is required that will cover the two main
buildings of the Calasanz school. For installation of wireless network access point proper area needs to
be demarcated. This is done so that no other source in vicinity can interfere as well as effect
performance of this wireless signal. Redundant device is required in case anyone fails then this device
could be used for the wireless communication.
User Centric Design Concept
The network designing is done by following concept of user-centric design as well as principles
so that network usability increases as well as network designing is done keeping in mind requirements
of user. To reduce the response time of this network, various research designs along with its techniques
are utilized in order to redundancy of this network which will facilitate a reduction in response time
which in itself is very crucial for an effective working of the network. The network issues and error are
solved in multiple stages so that the network’s structure does not becomes complex and it will also
allow aligning the different needs of users with the network.

OVERVIEW OF INTERNETWORKING
The network diagram for Calasanz school is prepared for segmenting the network with the
application of VLAN and Subnet. Here a central router is used that is connected with the ISP for
providing internet connectivity to the users. For efficiently manage the network distribution and the
wireless signals the wireless network is connected with the second interface of the router and it broken
into 7 subnets for dividing the network according to the department name. The first interface is used for
the management of wired connection and allowing distribution to the PC connected in different areas of
the network.
Outcomes
An expected outcome of this network project is designing an effective wireless as well as wired
network along with gaining sufficient knowledge about its switching and routing technologies along with
various other element that are essential in developing a network framework. The above knowledge will
also assist in identification of network devices which are required in network development while
deploying solutions of this network without having to affect teaching schedule of the concerned school.
The successful deployment of this network will assist into creating a stable and string coverage for its
WiFi signal thereby supporting school’s education in several ways. The WiFi will assist users into using
the resources of the school even outside their classroom and library through their laptops, smartphones,
iPads or other smart devices. All issues related to connectivity in the network which was face in pre-
existing network would be eliminated through the development of this network framework. The
development of network is done through configuring VTP servers with various switches along with a
configuration of layer 2 device with VTP clients so that all VLAN information that are configured in core
switch are transferred to various devices automatically. If performance of network is to be enhanced,
need for maintenance and training for management of different network platform should not be
stressed upon ensuring simplified controlled and managed network solution.
Limitations and further development
A deployment of centralised wireless solution within the network structure is an important
limitation that has been identified while developing the network. An enhanced encryption algorithm in
various access points of the network is also among the most important priority that needs to be
resolved while developing network solution. This will enhance the security aspect of this network so that
network attacks could be avoided. Flow of packets of data has to be monitored so that passage or access
of any sensitive information could be avoided. This is to be done by monitoring the whole network

through wireless central location. Avoiding all interference sources while deploying the access points of
the network is also very crucial so that the strength of the signal is similar throughout the network.
Conclusions
This report on the network development for Calasnaz School concludes that developing this
network solution could greatly improve learning as well as teaching environment of this school.
Through proper research and identification of various hardware and network devices, a cost effective
network solution could be design for this school. After creation of an efficient design of this network,
various department of this school is analyzed so that it could be into multiple VLAN which would then
help in enabling access to different services according to different types of users. The selection of
wireless network has been done on the basis of coverage area along with speed at which it operates so
that it's users could access the resources of internet at an effective speed.
