1.     Project Scope and Requirements

1.1.           Project Scope:

The purpose of this project is to design the network of the visited industry. The visit was arranged at RMIT (Royal Melbourne Institute of Technology) public research university situated in Melbourne, Victoria. The university requires an effective network design to connect their computers, laptops and mobile with internet connectivity, Not only in single department however overall university campus. In the current scenario, the network is inferior and lack various functionalities. To name a few; colleges go through issues like an invasion of a computer virus, DDoS attack, spyware, phishing, junk emails, and abuse of internet platforms [1]. Therefore, the scope of the project is developing a network design for RMIT University Campus. Additionally, this network can offer solution over security and privacy concern.

1.2.           Project Requirements

The brief session held with RMIT university network engineer at their campus lab. After the current network assessment, some of the new network project requirements are presented.

• Network design requires for campus only through VLAN, and the concept of IPs configuration [2].
• Flexible and reduce complexity in context to cabling, control plane, and manageability [2].
• Use of appropriate protocols, addressing scheme, and budget estimation for hardware/software resources is mandatory.
• Network design with a minimum of 5 routers, 15 personal computers, 4 VLAN, and 7 switches should be available.
• Use of appropriate network simulation software such as CISCO packet tracer is mandatory.

In this setup of the Network, there are 15 PCs, 7 switches, 4 VLAN, and 5 2911 routers.

2.2.           IP Addressing Scheme

An IP address is a crucial part of the network design of the RMIT University campus. Internet Protocol is a mechanism which provides communication on the internet-connected on a network [3]. Concerning the current network IP addressing scheme is identified in the table. The components of the IP addressing scheme are as follows.

• Device: 20 personal computers attached to the network.
• IP address: IP address uniquely identify information from one computer to another [3].
• Interface ID: The interface identity is unique and determines an interface on network link [4].
• Subnet Mask: The subnet mask separates a large number of hosts into a small portion of a larger network [5].
• Class: The IP addresses divides as per bit position of a network ID and host ID in categories A, B, C, D, and E [5].

2.3.           Routing Protocol Justification

In this case, a dynamic routing protocol is implemented to exchange routing information for unknown traffic. The data is automatically gets collected in routing tables. We propose the use of RIP routing protocol for router connection in section 3.3 RIP configuration. RIP protocol is known as distance vector routing that works on hop count to achieve remote network [6]. We are using RIP protocol because it is dynamic and works well in a small university campus. During Access Control List will provide network engineer traffic control over RMIT university campus network effectively [6].

4.    Timeline and Budget Estimation

The time and budget estimation are determined for hardware, software and network requirements. The hardware is required to connect on the network designed for university. As per request, we invested on 15 computers, five routers, seven switches, data cables, and servers. For CISCO packet tracer software, we had licensed copy. Additionally, human resources were implemented from university and network consultant. We estimate a total budget of $25850 out of which hardware and software components are $23,200, and human resources are $2650. Further, the tentative project timeline is calculated as 25 days since the first meeting to the final delivery.

5.    Summary

In brief, RMIT university needed a network which could protect them from threats and cyber-crime. Therefore, project demand was to make a network design that is safe and secure for university staff. We identified project requirements in the first meeting and discussed basic needs with university professional network engineer. He discussed current issues and explored the concept of a network that will provide privacy and security over the internet. The IP addressing scheme is also identified for a large number of hosts in a systematic tabular form. Dynamic routing protocol was established to provide traffic route checking. The configurations are projected with proper snapshots in the report. The total estimated budget for hardware, software and networking components, as well as human resource and logistics, is proposed as $25850. Therefore, network design for university is sent for approval to achieve better employee workspace.
