Chase Grammer School Network Project: Internetworking Solutions

This project outlines the development of a unified network solution for Chase Grammer School, aiming to enhance the efficiency of both wired and wireless networks. It addresses challenges such as bandwidth allocation, user prioritization, and transmission speed requirements. The solution employs a user-centric design concept, involving iterative phases of specification, requirement identification, design creation, and evaluation. Key hardware components include Cisco routers and switches, along with DHCP and web servers. The project's outcome is to provide improved network performance and security, with limitations acknowledged and future improvements suggested. A network prototype is designed and tested using Netsim, demonstrating the proposed solution's viability and potential.

OVERVIEW OF INTERNETWORKING
Project Scope
The scope of the project is to develop a unified network solution for increasing the efficiency
of the wired and wireless network of Chase Grammer School. New technology is needed to be
implemented for the removal of the bottleneck condition of the wireless network of the organization
is analysed for the development of the network plan. The selection of the technology is important
for the management of the wireless connection and elimination of the network security risk
associated with the development of the network. The communication channel for the wired and
wireless network can be divided for eliminating the data traffic congestion and multiple link should
be used for connecting the network device such that the performance and uptime of the network
can be improved. The requirement of the school and the users connected with the network is
needed to be identified for aligning the network with the needs of the users. The network is
designed for handling multimedia packets and allowing the users to connect multiple device with the
wireless network.
Challenges
There are different challenges faced for the development of the network solution and they
are categorized below:
Identification of data types and allocation of bandwidth – The type of data needed to be
served should be identified and according to it bandwidth is needed to be allocated for the
supporting the transmission of video, voice and text.
Identification of number of users and levels of priority – Priority of the administrator, staffs
and the students are different and estimation of number of users connecting with the wireless
access point is a difficult task. The network is designed by assuming the priority service and sufficient
bandwidth is allocated such that the performance of the network is high.
Identification of transmission speed requirements – A transparency is needed to be
maintained between the user and the network should operate quickly for reaching the destination
address. The network is designed with an average throughput of 20 mbps for each of the user and
for transmission of large files this can cause bottleneck.
User Centric Design Concept
The network solution is designed by keeping in mind the requirement of the user using the
network and it is developed in multiple phases. An user centred evaluation is done for the

improvement of the user experience and an iterative approach is used for the development of the
network solution. The phases involved in the user centred design process are given below:
Specification of the context of use – Identification of the people using the network and the
service and the condition and reason for using the network.
Specification of requirement – Identification of the requirement of the school, goals of the
user that should meet for successfully develop the network.
Creation of design solution – Development of the network design in different phases and
building a prototype of the solution before completion the deployment of the network.
Evaluation of design – Testing the usability of the network by performing different types of
test on the prototype of the network.
Different types of software development lifecycle model can be selected for the
development of the network and a project plan is needed to be created by determining the task
needed to be performed for the development of the network.

Outcomes
The main outcome of the project is to develop the network solution by eliminating the
current problems faced by the users of chase grammar school. The are needed to be covered by the
wireless network is needed to be identified for providing wireless service to more number of user
and improvement of the network performance. The network bandwidth is managed for increasing
the efficiency of the network and two different subnets are created for the network for keeping the
wired and the wireless network separated from each other. The department of the school is needed
to be identified and the network is needed to be divided into multiple vlan for increasing the security
of the network. The wireless access point installed in different location of the network is needed to
be configured with security encryption algorithm for securing the access point form the external
agents.
Limitations
There are different limitation for the development of he network and it is needed to be
eliminated for increasing the performance of the network and improvement of the user experience.
The area needed to be covered by the network should be identified for estimation of the number of

OVERVIEW OF INTERNETWORKING
wireless router needed to be installed for covering the workplace area. The PCs connected in the
local area network should be installed with antivirus software for detecting the malware, virus,
trojan and the other threats such that it does not affect the network security and performance. For
the wireless network the area of installation of the wireless router should be evaluated such that
there is no obstruction or electrical source nearby that can affect the signal strength and quality. A
proper cabling plan is also needed to be created such that it sufficient bandwidth is available to the
user connected with the local area network for enabling them transmitting data packet between
different source and destination address of the network.
Conclusion
From the above report it can be concluded that for the development of the network an
analysis is needed to be made on the requirement of the user and identification of the task that is
needed to be performed for the development of the network solution. Focus is given on the current
challenges faced by the users for using the network and the technology that can be implemented for
mitigating the problem is evaluated for its implementation in the current business process. An
evaluation is made on the user centred design concept for aligning the network with the current
needs for increasing the usability of the network. A prototype of the network is created in netsim
and configured according to the requirement for the identification of the error and improvement of
the performance of the network.
