needs of the organization such as management of the voluntary service in different university
is analyzed and a network solution is proposed for increasing the efficiency of the operation
of the organization. A top down network design methodology is used for the development of
the network infrastructure and the physical and logical design of the network is proposed in
the report. The details of the device required to be implemented and their associated cost is
also given in the report for estimation of the budget for the deployment of the network
solution. A test plan is created for analysis of the proper working of the network and the

1. Project Goals
The main goals of the project is to develop the network design for A4A according to
the requirement and meet all the business needs of the organization. The developed network
is required to be efficient such that it is able to carry a huge number of request and no
congestion of delay in transmitting of the data packets is faced.
2. Project Scope
The scope of the project is to develop the network maintaining the technical constraint
and increase the efficiency of the current business process of the organization. New
technologies are available and it is required to be selected and aligned with the requirement
of the organization to develop an efficient network design for the organization. The network
solution proposed for A4A would help to remove all the constraint faced by the organization
and increase the communication between the branch offices located at different geographical
location. The implementation of the VPN communication would help to remotely access the
organizational resources of the organization and increase the productivity of the employees.
3. Design Requirement
a. Business Goals and Constraints
The business goals and the constraint identified for the development of the network
solution for A4A are listed as follows:
 The main goal of the organization is to connect with the network of different
universities and provide academic related service to the universities for
increasing the efficiency of the teaching process but the for the establishment
of the connection with the university network permission from the university
is required to be taken.

COIT20264 NETWORK DESIGN
 To provide maximum security and safety of the university and student
information by encrypting the communication channel and the database for
avoiding the risk of data theft or data manipulation. A proper encryption
algorithm is required to be selected and it acts as a constraint for the
encryption of the network infrastructure
 The organization should have full access of the network and the components
and limit the accessibility of the members for increasing the security of the
network. The users required to be provided the full control is required to be
identified or can cause a risk for the network.
b. Business Goals and Tradeoffs
The main tradeoff of the business goals identified are listed as follows:
 To maintain the confidentiality of the network solution such that the
authorized personnel have the access of the sensitive information such as the
password and login information of the network.
 To maintain the integrity of the data such that the authorized personnel can
change the network information and protect the network from unauthorized
access.
 To develop a security plan for meeting the security requirement of the
organization and listing of the network service that is required to be offered to
the University for Management of their system.
c. User Community and Network Applications
An analysis id require to be made on the group of users using the network and the
service offered by the organization and different Vlan are required to be configured for
different group of users for securing the network from unauthorized access of the sensitive

organizational information. The main users of the network infrastructure are the small public
and private universities and colleges. Different types of service are provided to the colleges
and the universities for reducing their management cost such as supervising on a research
project for the students and teaching of subjects. The students can avail the service by
registering on the information system of A4A and can get shortlisted by passing an interview
conducted by A4A staffs. The network is thus required to be connected with the university
portal and the registration module is require to be merged to get the information of the
student.
d. List of Assumptions
For designing the network solution for A4A the following assumptions are made;
 To develop a central database for connecting the branch office and manage the
whole network from a central point
 The organization have the capability to grow and the users of the network
would increase with time and the network is required to be expanded
 Proper funding’s would be available during the course of development of the
network design
 All the users of the network would have knowledge and is able to use the
network efficiently
 The servers used in the network is kept under lock and key for securing the
network from physical accessibility

4. Logical Network Design
a. Logical Network diagrams including addressing and naming
b. Explanation and justification of the logical design
The logical design is created to cover the different branches and the university
locations. The routers are configured with proper addressing schemes for connecting with the
interface of the other network. The requirement of the organization is required to be analyzed
and a list of the university to be included in the network is required to be listed for the
development of the network solution. The proposed network solution meets the security
requirement because VPN connection is used for the network to connect with the remote
hosts and the database id encrypted with proper encryption algorithm to secure the identity
and the personal information of the students. There are different alternative of the network

solution available such use of the leased lines network but it increase the cost of the network
and the security of the network can also be get compromised.
c. List of routing and switching protocol and security mechanism
The following are the routing protocol used in the network:
 OSPF
 EIGRP
 RIPv2
 IS IS
The following are the switching protocol used for the development of the network.
 Spanning tree protocol
 VLAN trunk Protocol

c. Explanation and justification of the selection of the device
From the above table it can be alluded that for the preparation of the network design
the above devices are necessary and the minimum and maximum number of devices required
are given for estimation of the budget. A layer switch is used for enabling Vlan and wireless
routers are used for enabling wireless connectivity of the device and reduce the cabling cost.
Printers, server cabinets and furniture are required for installation of the devices. Software
such as Microsoft office suite, windows OS and other development software are required for
the management of the network.
