This report is focused on network design for an organization Excelfior Ltd. which is a Digital Communication Company based in Australia. The organization specializes in various services such as designing, hosting along with management of corporate websites. It has been identified that there are various issues within the existing network as it is old and it is not capable of fulfilling requirements of the organization. Hence, in this report, the requirements has been gathered in context to the various components of the network. The discussions has been presented on the techniques that were used for collecting the requirements and a new design for network has been proposed for the organization. The performance metrics for the network has also been defined in this report to demonstrate performance of the proposed network.
1.1 Requirements Gathering for Users, Devices, Application and Network
The requirements in context to the Users, Devices, Application and Network has been gathered by designing a questionnaire as presented below:
1. Do you think that the existing network is able to fulfil your requirements?
Yes
No
2. Do you think the uptime and bandwidth of the network is stable in the organization?
Yes
No
3. Do you think the network is able to meet your desired goals while operating in this network?
Yes
No
4. What type of applications are being used for your daily work?
5. Is the network performance stable and as per your requirements?
Yes
No
6. Does the network support scalability in case of increase in number of users?
Yes
No
1.2 Techniques used for collecting requirements
For collecting requirements, the various techniques that are used in context to the case of Excelfior Ltd. are discussed as below:
Brainstorming: This technique is used for elicitation of the requirements so that unique and various ideas could be gathered from determined group of users or people. In this technique, all the possible issues and solutions for resolving them has been determined for detailing the opportunities. Through this technique, wide range of possibilities has been analysed in context to the gathered requirements. This technique helps to prioritize the possibilities as it helps to locate smaller things from a wide range of identified possibilities to reflect ideas.
Use of Focus Group: In this technique, a group of people was identified that included users as well as management staff of the organization. The focus group was used to gain feedback about the existing network so that the needs, opportunities along with the problems can be collected for suitable designing of the network The requirements has been collected through this technique and after that refining and validation was done for the determined requirements. This technique is different as compared to brainstorming as this technique is used for managing processes in context to specific participants.
Interviews: This technique involved interviewing the users along with other stakeholders to determine their requirements particularly. The interview was carried out to determine their expectation and goals such that the network can be designed to fulfil their requirements. The inputs from the interviewees are analysed and weighted so that better analysis of their requirements can be done for designing the network.
Observation: This technique comprised of observing the users or a specific group people in terms of their usage of the network or applications. The process flow being followed by the users has been observed to determine the requirements. There are basically two type of observations that is passive and active observation. Passive observation has been used in this case ass it helps to acquire better feedback for refining the requirements however, active observation is suitable for understanding the existing business process.
Requirements Workshop: This technique is also referred to as JAD (Joint Application Design) which comprises of workshops that are efficient to gather requirements. This technique is more organized as well as structured rather than brainstorming sessions where the participants gather together for documentation of requirements.
2.1 Design of the Network
2.2 Justification of the design
The network has been designed to facilitate the requirements gathered for various components of the organization. The network has been designed such that it will be able to support the various departments in the organization. The devices or equipment being used in the network has been implemented according to needs of the various users in the organization. The designing of the network has been done in such a manner that it is flexible and scalable if there is increase in number of users in the organization. The network has been divided into different subnets for each department so that the access permissions or levels can be easily implemented. The design of the network has been developed such that security measures could be easily implemented within the organization. The designed network will also ensure that there is no packet loss or decrease in uptime such that the business performance is not hampered. The network design is suitable for the organization as it would support the increasing number of users within the organization without additional costs which means that the network can be easily expanded.
2.3 Network Performance Metrics
The performance is considered as the major criteria to determine success of the designed network and it can be measured with the help of different network monitoring and analysis tool. There is a requirement that a minimum of 100 Mbps bandwidth have to be maintained such that there is no congestion or heavy traffic within the network. The identification of errors has been analysed with the help of Ping test and show run functionality to show bandwidth of the network.

Conclusion
From the overall analysis and discussion presented in this report illustrates that the proposed network design will provide the organization with a secure and domain based network to suit their needs and requirements. The proposed network design is suitable for the organization as it will help to improve the processes existing within the organization. The proposed network design is scalable and robust in nature and it will be able to handle expansion in the number of users so that there is no modification required with the increase in users. The proposed network will help to control the access levels of the users and prevent unauthorized access with the help of suitable encryption mechanisms. The designed network will ensure reliability and as per the performance metrics it is also does not have packet loss. It means that the network will facilitate data transmission smoothly at a faster rate without any loss of data while traversing through the network.
