Detailed Network Design and Implementation for A4A Organization

This report details a comprehensive network design for the Academics for Academics (A4A) organization, which has offices in Sydney and Singapore. The project aims to create a secure wireless network to facilitate online registration for universities and colleges, and to enable volunteer recruitment. The report includes an executive summary, project goals, and scope, along with design requirements that encompass business and technical goals, user communities, and assumptions. It presents both logical and physical network designs, detailing IP addressing, network devices, and justifications for the design choices. The report also covers routing and switching protocols (BGP, RIP, EIGRP), security mechanisms (including firewalls), and a total cost estimation. A test plan and reflection section analyze user, business, and security requirements, compare alternative designs, and discuss the top-down network design methodology. Finally, it concludes with final documentation, designed network requirements, suggestions, and references, providing a complete overview of the proposed network solution.

Executive Summary
The A4A organization interest to design a comprehensive network to provide the
wireless connection for an organization. It has the two branches such as head office and
branch offices. The head office is located at Sydney and branch office is located at Singapore.
The A4A organization funds all of its activities and projects from the public donations. It has
10 employees. The six members are located in Sydney office and four members are located in
Singapore office. It was stablished to help small private and public colleges and universities
in southeast Asia and Australia. It creates the proposed network to universities and colleges
are register the online by using wireless connection. The proposed wireless connection easily
communicates the two offices. It provides the secure wireless connection between the head
office and branch office. It meets the various requirements like security, user and business
requirements. It delivers the secure network services for an organization. It easily enable the
student to apply for recruitment to be volunteers in institutions.

Project Goal and Scope
Main Goal of the project is to design a comprehensive network for Academics for
academics (A4A) organization. The A4A organization has two offices like head office and
branch office. The A4A head office is located at Sydney and branch office is Singapore. The
A4A funds the overall of project and activities for public donations. The A4A organization
has the one team to provide the funds for public donations. It has a team of 10 members. The
six members are located in Sydney office and four members are located in Singapore office.
The A4A organization was helps to small private and small colleges and universities in
southeast Asia and Australia. The A4A head office and branch office are have the local
network. The A4A organization needs to creates the wireless connection by design the new
network design. The current A4A network does not allow the institutions such as universities
and colleges registrations. So, the proposed network meets the various requirements after
analysis of the A4A current network. It allows the online registration by using the wireless
connections. It easily enables the student to apply the recruitment to be volunteers in the
institutions. The proposed network provides the security and productivity and it keeps the
member information securely. The Proposed network design will be identified the design
requirements. It identified the technical goal and trade-offs for A4A organization. The logical
and physical network design will be created. The network component and IP addressing will
be identified.
Design Requirements
1. Business Goals and Constraints
The A4A organization analyse the business goals and constraints by using the top down
methodology network design. The Business constraints and goals are used to gathering the
below information for an organization. They are,
 It provides the high security
 It improves the communications between the client and server.
 It increases the revenue.
 It offers the better customer support and services.
 It reduces the operational and maintenance costs.

2. Technical Goals and Trade-offs
The A4A organization technical goals and trade-offs are analysed by using the top down
network design. The Technical trade-offs provides the following information like response
and delay time requirement, jitter requirements, packet loss requirement and bandwidth
requirement. The identification of technical goals is including the network adaptability,
availability, performance, affordability, scalability, usability and manageability.
3. User Communities and Network Applications
The A4A organization user communities are support the proposed network design. It
provides the end to end network solution and high network performance. The user
communities are including the group of users to sharing the best network practices on high
performance networking to raise the end to end network performance. The user communities
are identifying the set of users and their network performance by requiring the network
applications and resources (Jisc, 2017). The network applications are used to find the network
requirement to design a proposed network.
4. Assumptions
Various assumptions are applied during the network design to increase the network
design performance. They are listed below.
 Compatibility
 Reliability
 Availability
 Stability
 Scalability
 Integrity
