OVERVIEW OF INTERNETWORKING
Project Scope
The report is prepared for the development of a network solution for Chase Grammar
School and for the development of the network the scope of the project is identified. A case study of
”Case Grammar School Accelerates Learning with BYOD” is evaluated for the identification of the
needs of the school and the proposing the network solution for the school. The success of the
network depends on the selection of the technology an the topology for connecting the different
access point and increase the reliability of the network. The network is developed for implementing
technology for the improvement of the learning procedure and provide different types of teaching
and learning resources from internet sources. The mobile devices of the students are needed to be
connected with the wireless school network for supporting the student learning process. Currently
there is a wireless bottleneck condition and the cause of the bottleneck is investigated for the
increasing the wireless speed from 20 mbps to 100 mbps for each of the user. The real world
download speed limitation and the scope of improvement of the network and the risk of bandwidth
hogging should be eliminated for the development of the network framework. The network is
needed to be sub divided into multiple VLAN such that the problem is resolved and multiple access
point should be installed in the different areas of the network such that more number of users are
allowed to connect with the access point. The network is developed for handling different types of
data packets and ensuring that that the response time of the network is minimum and for its peer to
peer sharing is enabled and a survey is made for analysis of the coverage of the wireless signal and
install the access point according to it and allowing more number of users to connect with the
wireless network.
Challenges
For developing the network solution for chase grammar school different challenges are
faced and they are given below:
Estimating the number of users of the wireless network -
Poor performance of the network – If the performance of the network is poor the user can
face congestion and the data sent between the sources and destination may get lost. The network is
needed to be designed for handling spikes and select alternative routes for increasing the availability
of the resources.
Security – The unauthorised data traffic is needed to be restricted for protecting the internal
data of the organization. The vulnerability of the network should be identified and the tools that can

be implemented for the improving the security should be identified for the development of the
network.
Management of the configuration – The increase in the network size increases the
complexity of the network and thus it becomes a challenge for the management of the firewall rules
and encryption of the data traffic in the network.
Cost - The cost of the network device should be should be estimated along with the service
that is needed to be implemented for increasing the efficiency of the network.
User Centric Design Concept
The network design is created following the needs of the user of Chase Grammar school and
an iterative approach is used for the development of the network framework. The design of the
network is made following the goals and objectives of the organization and the selection of
appropriate tools and technology is essential for increasing the usability of the network. During the
development of the network framework focus is given on its usability and the network is customized
for meeting the needs of interaction.
Designed for users – The users are needed to be provided with access to different service
such that their performance can be improved and enabling them to involve in interactive computing.
Maintaining consistency – The network should be developed with multiple redundant link
and dynamic routing protocol such that if one of the link fails the alternative link can be selected for
reaching the targeted host.
Using simple and natural dialogue – Only the needful website should be available to the user
for allowing them to get relevant data from the network and improve their learning process. The
firewall should be configured with proper validation message and display it to the user when they try
to reach the blocked websites.
Reducing the unnecessary effort of the user – The network is designed such that it
compatible with the mobile and other device used by the user to connect with the network. The
wireless signal should be of 2.5 Ghz that are supported by most of the mobile devices.
Provide accurate feedback – The user should provide feedback if they face any problem
while using the network and it should be eliminated for the development of the network solution.

Outcomes
The report developed for “Chase Grammar School”, would help then network development
and the administration team to reduce the errors in the project. The limitation and the challenges
are easily identified in the previous stages of development of the project such that it can be
mitigated for increasing the efficiency of the network and provide better service to the user
connected with it. The topology that should be used for the development of the network framework
is identified and it also used for the identification of the number of network device and hardware are
needed for the development of the network. The networking protocols that should be used for the

OVERVIEW OF INTERNETWORKING
development of the network is identified and its alternative option is also identified that can be
applied in case of failure of the primary option. The bandwidth allocated to the user should be
managed and the unnecessary broadcasting message should be reduced with the application of
static routing such that maximum bandwidth is available to the user.
Limitations
For the development of the network solution a network prototype is designed in Boson
Netsim but it have some limitation that is some of the network device that are needed for the
development of the network are not available in the simulation tool. A BYOD policy is needed to be
developed according to the business rules of the school and the sites that are needed by the student
is needed to be identified for allowing the user to access them and the sites that may be harmful
should be restricted to be accessed by the student such that it cannot be visited and the network is
kept secured. The end user device connected with the network should meet the requirement such
that no virus, malware or external threats are transmitted through this devices and affect the
network. The interference from the other electrical fitting and device or barriers such as walls and
building structure can also reduce the coverage range and thus the wireless access points are
needed to be installed in an open space to cover larger space and increase the accessibility of the
proposed network structure.
Conclusion
The network solution proposed for Case Grammar School for improvising the learning
management system and allowing the user to access different learning sources from the internet
that is essential for the learning journey. For the development of the project the scope of the project
is identified with the challenges that are faced for meeting the needs. An evaluation is done on the
requirement of the users for aligning them with the project and develop the network solution
according to the needs of the user. The bottleneck situation in the current network that is causing
problem is evaluated for proposing a solution to the problem. The current network solution is
developed by subnetting the network into smaller subnet and allowing the users to share their
resources with the users and eliminating the clogs and traffic congestion in the network.
